My 2004 C70 is exhibiting an odd problem. After starting the vehicle, normally all electrical systems turn on immediately. About 6 months back I noticed a delay before the headlights, dash lights, turn signals and a few other items would come on. (Not all systems are affected -- the radio is fine.) That delay can now be up to several minutes.

Anyone experienced this? Suggestions?

Thanks very much.

I have a 2010 C70 D3. A while back I returned to my car to find that all of the windows were open. I put it down to perhaps accidentally pressing the all window open button when I shut the door.

The other day I again returned to my car to find all the windows open. However, it had been raining heavily that afternoon so I expected to find the interior sodden. To my relief there was no water at all in the interior of the car. This would appear to prove that the windows all opened of their own accord some considerable time AFTER I had parked up that morning.

Has anyone else experienced this problem? I am now paranoid and keep having to check my car every 30 minutes or so. Fortunately my parking is always in a secure area but I worry that the next time this happens I won't be around to catch it before it rains again!

Hi. I just picked up a 1999 C70 with a canvas convertible. The convertible top seems to not be completing its cycle. It goes down fine. When closing the top, it appears to work fine, until the very last step...wherein the rear window latches itself down to the rear trunk lid. It doesn't go all the way down....any ideas? Has this happened to anyone else? Hhhheeelllppppp!!!!!

Help please!!!
I have an 04 c70 and I first noticed that that the rear window demister was not working. I have also noticed that the chime at the end of the lowering or raising of the top does not sound. Also the windows do not lower when the top starts its cycle.

From what I read on VADIS the control module is suppose to lower the windows 5cm at the begging of the cycle. Also the boot is not suppose to be able to be open via the switch (I can open it while lowering or raising the top but it does stop). Also the rear defroster is shup off when the cycle is not complete which is why I think the defroster does not work.
I have checked the fuses and they seem to be fine. I found a buzzard or Relay that reads "Audible Hood Warning Unit 8611543" I204
I am not sure if this is the relay for the chime. I tried to test it by putting power to the connectors but I did not hear a click.

Any help is greatly appreciated. Thanks..

Good Afternoon,

I have a 2004 C70 convertible... This car has 100K miles and has been great... Just strted having a problem.... the passenger side window started not working... this problem is intermitent... sometimes it works just fine and other times nothing happens when I press the window button either on drivers or passenger side... When the window does work, it operates perfectly without any strange noises.... or issues.

Other windows operate perfectly.... I have noticed, when I shut the passenger door a little hard, the window starts operating again.

Any advice would be gretly appreciated.

Thanks

The driver seat in my wife's car is having some issues.

The seat will move back and forth but only to about half the travel available for the seat. This doesn't present an issue for her since halfway on the track is the perfect distance for her driving the car. On the other hand, If I need to drive the car I feel like I'm crammed in to a Yugo.

Any thoughts on what is causing this issue? Once the seat reaches the half way mark the motor just cuts out and it wont go any further.

Just had something strange - she started running very rough, with cylinders starting to miss over about 1600rpm, and running really badly about 3000rpm. Lots of noise and some clattering sounds on starting her up.

The cause? Automasters found that two of the little rubber straps that suspend the exhaust had snapped, allowing it to 'bounce/bang' on the top of the transmission. Replaced the two rubber straps and she's back to how she was. You'd not think a loose exhaust could cause the engine to misbehave or produce so much vibration...

Hi (Apologies for posting my last post twice! Rookie error

)

I was just wondering if anyone had any experience of tuning the T5 (particularly in the C70)?

I am seeing a few cars for sale that are 'chipped' to 300BHP - Is this a standard tune for this engine? I know that other (newer) models like the S60 (R?) come with the higher power, but I don't know if it is exactly the same engine etc.

Are the any problems with tuning to this level, and is there anything you should look out for? Any thoughts / general info?

Thanks, Oliver.

Hi all,

If anyone knows of a C70 T5 coupe, with the 5 speed automatic gearbox for sale, please let me know.
I've been trying the usual places (Autotrader / eBay / Gumtree), but there aren't many around in good standard condition / in my price range. There also seems to be a lot of dealers that don't know the difference between a T5 and any other turbo model...

For instance, I'm very interested in something like this: http://www.ebay.co.uk/itm/Volvo-C70-2-3-au...l-/321040373602 But according to the DVLA, this is actually the 2435cc model...

I'm looking at spending around £1500, so I'm not expecting anything brand new obviously.

Thanks, Oliver

Hi all, my 2006 C70 T5 has recently started to randomly display the anti skid service required display. Coupled with this, the wipers start going and the indicators cannot be used! The car runs ok but is obviously dangerous as I can't indicate. Any help will be gratefully received before I have to take it in to be ripped off. Many thanks

So I replaced the heater core in my 2002 volvo C70 about 2 years ago and everything had been running fine. Now all of the sudden I have coolant in the floor pan on both the driver and passenger sides of the car. When I replaced the heater core before, the coolant was underneath the carpet on both sides. This time the coolant is not under the carpet, it is even further down below the carpet, under the rubber and foam that is just above the floor pan. I have pulled back the carpets and cut open the rubber and the foam to expose the floor pan. Here is the strange part - the heater core doesn't appear to be leaking at all and even after running the car for over an hour with the heater running full on, there are no visible leaks. Last time it was easy to see that the heater core had gone bad and was leaking. I also looked at the ac drain that is just under the heater core and that appears fine as well. I am pretty stumped here. Has anyone else experienced this or any ideas what to check? Again, no drips or leaks from the heater core and I can't see anything coming from the 2 coppers pipes in the firewall. Is there anywhere else that coolant could be leaking from that I haven't mentioned?

Thanks for any thoughts,

Mike

Hi I recently purchased a used 2007 Volvo C70 t5 hard top conv. with 60,000 miles on it. Runs great and we love it. The other day I noticed some type of oil or lubricant on the rear bumper that looked like it came out of the trunk lid. Appears to have the consistency of vegetable oil. I opened the trunk and the weather seal was covered with this oil. I think it might be for the convertible roof operating mechanism but not sure.
Has anyone run into this problem before and how expensive was it to fix or is it something I could handle myself as I usually do all the regular maintenance on my vehicles. I have tried to find a service manual for the car but no one seems to carry it.
Thanks

Hi, recently my car battery died so i went and bought a new one, once id fitted the new battery on my c70 it started misfiring and the revs were going up n down, i checked the label and noticed that the new battery reads 72 ah but my old battery reads 70 ah does this mean they have given me the wrong battery and is this whats causing me the problem? thanks all

I have a "bulb out light" on my dash, but all of my bulbs are functioning. I understand that you should change bulbs in pairs (or at least make sure the bulbs are the same wattage), but I have not changed any bulbs recently.

The light just came on.

I tried uninstalling and reinstalling all the bulbs one by one to no avail.

Anyone know what can cause this?

Thanks,

Paul

Hi everyone

Any help is much appreciated.

Hi all,

Desperate for some advice, the sat nav screen in the dashboard has started popping up displaying the message 'please insert disk' this only happens in the cold weather (ie first thing in the morning) but is really annoying. How do I eject and reload the disk, and is it likely to be a connection issue at the back of the unit I can fiddle ith myself?

Thanks

Good evening everyone, I have a 2004 C70 Convertable Turbo with a transmission problem. Here are the symptoms. when I first crank the car in the morning and take off its fine and within about 10 miles the Transmission starts to have a shifting problem from first to second but once I get over about 20 MPH its seems to be ok. well when I start slowing down it has a hard down shifting but this only happens when the car is warm or hot. However, when I am on the Interstate I have no problems. Took it to a Volvo Dealer and they said a transmission, but why does it only do it when its hot and not cold. I know the Volvo C70 has a shift soleniod around transmission and a few other electical components. Can someone please help me pinpoint this problem before it costs me a arm and a leg.

Hello all,

My wife just got a 2007 C70 with about 60,000 km on it here in Switzerland. Bought it through a used car dealer and other than regular services nothing else noted in the service logs.

About 1 week ago she started it and on trying to pull out of her parking she got a fault message displaying (in French...rough translation was "engine fault") and noted very little throttle response. After restarting 2 or 3 times error message stayed but she could at least get home. During some of the trip she found very little response from the throttle.

Day after everything was fine.

She took it to our Volvo dealer mechanic and the Volvo diagnostic kit showed an error code associated with the accelerator pedal. Advice was wait and watch as the car at that point was running normally.

Today it happened again. I've since googled throttle C70 etc. and seen that earlier model C70s did have some problems with their throttle modules. Not sure if and when it changed but if I read things correctly may have been 2006. As above, this is a 2007 model.

What do people think we should do? At this point my plan is to go to our local Volvo dealer who has started looking after the car (the used car dealer we purchased through is 3 hours away in another part of Switzerland), as they said when my wife took it in for its first service that it would be under the 10 year/100,000 km warranty. I would like to know before talking with the local Volvo dealer if there is a known issue with the throttle module that applies to the 2007 models.

Thanks for any advice,

Dave M

Hello

This is my first post in this forum.
I hope You understand me because sometimes I have a problem to translate the "engine parts" from polish to english, but I will try.

Ok, the main problem is, that my C70 don't have ~240 hp. Now..it has about ~200 or less and about ~280 (not 330) of torque.

My C70 is 2.3 T5, from 08.1998 - so when I decode my VIN number I get that my car is 1999. (I have a electronic throttle, coil, 2 lambda)

What I checked and repaired:

- new (regenerated) Turbo - I changed from 16T to 19T
- new TCV (pierburg)
- all pipes between Turbo and TCV are also new
- new first Lambda
- remove catalyst
- ECU software - is oryginal
- MAF sensor - I checked about 3 different and new MAF sensors
- timing belt - here everything is ok
- no "leaks"
- electronic throtte (magneti marelli) - is clean
- Crankcase Ventilation System - is clean

There is no Check Engine, no errors, but it still has no power.
Few days ago I drove C70 2.0 225 hp and it was much faster.

Tomorrow I will replece new "knock sensor" - and this is the last part I will check, because I have no more idea what can I check.

Do You have any sugesstions what can I check?

Thanks

I maybe due for a battery replacement at my 09 Volvo C70. Volvo OEM battery is similar to one at my dad's car like almost 40 years ago :-). My BMW motorcycle came with a Gell battery and I later upgraded to an AGM Oddysey battery. One reason why I want to upgrade the battery to AGM is that I drive my C70 only once or twice a week. It seems that AGM batteries hold charge better for longer time. Any ideas to which battery to get?

I have a Volvo C70 T5 Hardtop (2006), when the roof is closed I get an annoying noise coming from just above my head (in the driving position) to the right where the roof slides into the strut on closure. Its like somethings loose and bouncing around, do/can these roofs need adjusting overtime ? Is it something a Volvo garaage can undertake ? I also get an annoying squeeking coming from the rear of teh car when teh roof is open its liek 2 bits of rubber or leather rubbing together.

She's a lovely car and after awhile your brain blocks out these annoyances but I'd love to get them fixed, anyone had similar experiences ?

regards

Carl

I have 2004 C70 in NY I have to do inspection I replaced the ambient temperature sensor that is on the bottom of radiator and deleted code P0072 sensor was broken I plugged it in and have it tie rapped because it was hanging and I didn't have time to lift the car up to find location where it belongs.Also I have no temperature reading on my dash which has been like that for a while which I assume is the other sensor in the right side mirror.Now I have the I/M monitor on my OBD showing C EV O but no other number codes anymore.Also when ever I plug in my OBD on the first reading it shows ok but after that everything shows
C EV O even when I drive with it.
I understand that you have to drive the car for a few days/miles to go back to normal Does anyone know how long it will take to reset(days/miles) I just want to make sure that its not another problem I drove about 60 miles
Thank You

Hi All - First post here. Trying to get some guidance selling my mother's C70. This is not my car so I dont know every detail about it yet. It is in great shape overall and has relatively low miles (102k). My ad and some pics are below. I have it listed at $7,250. Besides the classifieds here where else should I post? Is my pricing too high or too low? Anything else I should put in the ad? The car is located in Houston, Texas. Just looking for some feedback from the enthusiasts. Thanks.

The ad: Selling this one owner C70 for my mom! The owner is a grandmother in her late sixties. Car has been exclusively dealer serviced by Autobahn Motorcars in Ft. Worth. Nonsmoker. Kept meticulously clean and regularly maintained. Fueled with super unleaded only. Clean CARFAX available for review. Includes car cover (looks to be rarely used as car was always garaged), tool kit (still wrapped in original plastic), owner’s manual, 3 keys plus valet key. This low mileage car is a rare find. Its overall condition is well above average considering its age and mileage. The interior and engine are in excellent condition. The body has several minor cosmetic scratches and dings but nothing extraordinary. Michelin z rated tires are new. The passenger seat does not move back and forth. Other than that, there are no other known mechanical or other issues with this Volvo. This vehicle is being sold "as is". As with any used car, the buyer should have the vehicle inspected by a reputable mechanic prior to sale. Many additional pictures/videos available on request.

So - every once in a while, I come out to a dead battery. Electrical system checks out fine (alternator, ground, terminals and check for amp draw when the car is off - all good).

But - it still happens. Now - I have found a way to duplicate it - but - I don't know WHY it happens. Here is how I can drain my battery in a day, without leaving anything on (that I know of):

1) - Park car too close to garage to get garbage cans out (car outside as nice weather is predicted!!!!)
2) - Unlock car, put key in ignition without starting, just enough to release trans.
3) - shift to neutral and coast down driveway 10 or so feet.
4) - back in park, pull brake, turn off car. Lock doors.
5) - Consistently - by the next day - the battery is dead.

This happened several times, but, now it's happened 2 times on "purpose" to make sure that's what's happening. Even put in a new battery before "try" #2.

Anyone ever see something like this - where turning on the car but not starting it leaves something "on"? I couldn't find a post that referenced this scenario.

I have a busy week coming up- but next weekend - going to try and duplicate again - and after I cycle the key, transmission, brake - and shut everything back down - I am going to look for a drain on the battery and see what fuse makes it stop.

Anyway - I welcome any thoughts on this subject (including that maybe I am just crazy!)- but - this has been driving me nuts for a few years.

Hey Guys,
This is my first post on the forum and this is my first Volvo. I just purchased a 2000 C70 for $1500.00 and it has a few issues. The biggest one being that the drivers window won't go down. When I hit the switch I hear the relay towards the dashboard click but I don't hear the window's motor make a noise. I heard that there is a master controller for these cars but all the other windows work. If I am able to get the motor to run by hooking it up directly to the power source where should I look next for the problem? Also my convertible top is completely up and it won't go down. I'm assuming because the driver's window isn't working. But there is also a warning light blinking on the convertible top control button and a beeping starts when I put the car in motion, which I understand is a warning that top isn't up all the way. What could cause this issue? Could the two be related? and what is the troubleshooting process to find the problem. I can fix almost any automotive issue, I have lots of experience fixing my 1.8t Volkswagen so nothing surprises me and replacing the hardware won't be a problem I just need to know where to start looking. I don't have a lot of experience troubleshooting window and convertible top systems and I am confused as to how the two systems tie in together. Any input you might have will be appreciated. If you guys need any more info on the car please ask and I will post a response as quickly as I can.
Thank You,
-Marcus-

Does anyone have a wiring diagram for the heated seats. I have checked the voltages at the switch, the front connector of the seat and then also at the back of the seat. the switch and to the seat is good. In the back I get voltage going into the seat but it looks like it should return back to the connector, and it does not.

Also, if anyone has any good sources or suggestions for new elements and leather covers I would appreciate it. Thanks

I have a black on black on black 99 C70 with 95k, the wife liked driving to much so we just traded here 01 S80 for 02 C70 (Moondust Metallic, with beige top and interior, really nice car, drives much tighter than mine. Everyone around me probably thinks we are nuts; the 2 of us having the same car but I hated giving up my convert so we both have one now

It only has a few small problems:
1. Both side mirrors don't work
2. Heated seat on Drivers side does not heat up
3. Could use a new leather for the drivers side seat
3. All windows button only works going up

I'm am searching the forums but if anyone has some ideas on fixed I would appreciate it.
