1G (1995-2004) S40 Forum -

Under the hood of the S40 there looks like what seems to be (2) O2's in the front exhaust manifold. This is a 4 cy. I picked up a manual for the S40 on ebay, but when I plug in the vin # it doesn't show (2) sensors. Both sensors plug into the bracket located top and center on the firewall. Far left is to be the O2. I have an identical plug with the black, gray and two white wires in...

Wondering if anyone has ever experienced this problem:

2000 Volvo S40 1.9T
103,000 miles
Recently serviced, new timing belt, new fuel filter, new engine mount.

The problem began in park while idling. The engine began to rev to 1,500 - 2000 RPM on its own and than come back down to normal idle. It did this spontaneously many times. Thinking I could reset it by...

Hi all,

I've got a 2000 S40 with a double DIN radio (CD and Cassette). Anyhow, I have decided to get the replacement pocket from a dealer, as they seem to be hard to find - at least ones that will match the current interior.

So my questions are:
• If I were to try to install a new radio for myself, what should I look out for?
• I'll installing a...

Hi all,

I've decided to change OEM radio to pioneer. wired everything as should be (at least tought so), and found that sounds is comming only from front tweeters.
Did the long way of trying to sort it out. even get to justwnswer.com where all kind of "Experts" giving advises. Anyway ended up by finding DIN connection on the back...

I have been wondering what might be involved in correcting power lock issue with the back door driver's side. It only works manually it will unlock by pulling on lock only. It stays in the position regardless of locked or unlocked when the power lock button is used to lock or unlock with either the dash button or key less entry.

I guess my question is how do I open up the door and...

Hi,

I need to run a 12v feed from the battery to run an amplifier in the boot / trunk.

Can anyone tell me where I can get access.

From previous cars I presume there is a rubber 'grommet' somewhere but I can't find it.

I have a right hand drive model but I'm not sure whether this matters.

Any help would be great.

I want to know how to remove the back bumper so that I can fit a tow-bar. If I need to access the fixings via the inside of the boot - how do I take the buttons out? Would a claw hammer do the job?

Thanks in anticipation
Steve

Hello All,

Brand new to the forum, I've had a look all over the forum for this fault but not found anything to cover it off. My car is a 2001 T4 which has never skipped a beat in the 1 year I have had it.

However I have noticed over the past week that the car has a misfire when 1st started, this lasts for around 20 seconds and then dies off, although I am sure that it is...

Hello!

Is the Volvo S40 MY2002 equipped with rear seat belt pretensioners?

Thanks!

I am driving a 2001 S40 and I had it more than 4 times in the shop since I bought it not even a year ago. Right now it drives ok except one problem that kinda goes on my nerves. When I slow down, like rolling out to a red light and I dont push the gas or the breaks the car is shifting VERY hard at around 15 or 20 mph. Its an automatic transmission. When I accelerate there are no problems at all...

Hi all,
I'm looking into buying a 1998 model Volvo S40 2.0T.
The problem is the Speedo has stopped working (which won't really be a biggy to get fixed) and the ABS warning light is on. I know from other cars I've had in the past that this can generally be any number of minor faults but apparently it had been intermittent but is now permanently on. Does anyone have or has...

I was wondering how one would calibrate the trip computer so that the cumulative fuel economy that is displayed on the trip computer is what the actual calculated. Any ideas?

Hi to all,

Firstly thanks for a great informative forum. I have a couple of questions regarding my volvo (I've only had for two weeks so far).

1. I had the oil topped up and now I get an oil smell in the car. I check for spillage bt cant find any.

2. There is a ticking sound when the car is started from cold but goes away once the car is warm. It sounds like...

Hi,

The turn signals on my car are fussy - sometimes they work, sometimes they don't. It seems that they don't work when I first try to use them the first couple of times, but after that, they seem to work fine. I changed the fuse and when I first tried them they worked. However, the next morning, the same thing happened. They didn't work when I first tried them the...

I'm new to this site and I'm asking for help with my S40. Love the car but have a problem. I have oil coming out of the oil filler cap and the dipstick won't stay down. I checked the o ring on the dip stik it's in place. It's not a great amount of oil but I don't believe this is normal by any means. Is there a PVC valve on this car? It is a turbo. This is a great car...

Hi Guys,

There is a company in South Africa called Steves Auto Clinic, They remap the software on The T4 to push out 190 kw or 258hp and a top end of 290km/h or 180mph. The cost is R4500 or +- $ 700.00

Beyond the oil issue I presented I'm wondering if anyone is getting great gas miliage. I've tracke my car for the last two months for gas miliage. City and highway. The most impressive is the highway miliage. I changed to the K filter and installed NGK plugs with the addition of synthitic oil.
When I first started out I could push 38 to the gallon. After the changes I got 41 to...

I've just purchased a 2002 S40 1.9T, and It is just drinking the gas. On this tank, I have driven about 150km's and I've already used half a tank. The garage checked all my sensors and they say everything is fine...I can't even go 400km's on a tank. Does anyone else have this issue? Or does anyone have an idea what's wrong? I'm not driving the car hard either. ...

This is for those who have not read about my rather unusual (and drastic) solution to clearing a P0015. CMP sensor malfunction.

This pertains only when you are sure that the vehicle is running properly, all wiring has been checked, and the engine oil is clean and of the proper viscosity rating.

Try adding a pint of a product called "Seafoam" to the engine (in the...

Hi, i thought i'd put this question out to the experts out there, i have been told that to upgrade the turbo on a 1997 2.0t i can just bolt a t4 unit on, is this right? or is it a bit more involved than that? just wanted a bit more oomph, but dont want to part with the trusty steed yet default/blush.gif' ...

Hi

I bought a 2002 S40 T4 about 8 months ago and. I've been noticing a whining noise from what sounds like the turbo. This usually happens between 3k-4k RPM when I'm just starting to give it a bit more gas. As I press the accelarator harder the noise changes pitch, and if I give it enough gas the noise goes away, but as soon as I let of the gas again the noise comes back again....

Hello there. I was wondering if anyone has a clue about what's been happening with my 2004 Volvo S40.

About a dozen of times now my ignition key gets stuck after I try to turn off the engine. This happens basically at random times. I will park my car, and will be unable to pull out the ignition key. Sometimes all it takes to pull it out is to start up the car again, drive back and...

Hi all, I'm new to the forum, and having problems with my 99 S40 2.0, I noticed one of the headlights wasn't on so I went and bought a new bulb, fitted this and no difference, it seems the old bulb was fine too, when I moved the plug around (at the back of the bulb where the connections are) I heard the sound of a motor kicking in, then stopping, I'm assuming it was the height adjuster...

Hey guys, I have a problem. My 2004 Volvo S40 1.9T needs a new battery, and I can't find one at the local car parts stores (the battery books go blank when I turn to the Volvo page).

You mentioned you use Mobil 1. I also use Mobil 1 and have been for years in all of my cars. Do you think there might be a chance that the Mobil 1 is causing the problems?

I thought about changing the oil next time with the Mobil 1 High Mileage formula because they say it breaks down sludge and dirt deposits left in the engine from conventional oils.

Hello All,

For the first time ever, when I started my 2001 S40 and pulled it out of the driveway, a dashboard light with an upward pointing arrow lit up. As I had never seen this light before, I pulled over and turned off the car. After waiting 5 minutes, I started the car again and began driving and the arrow light was off. That was one day ago and it hasnt shown up again. Has this...

Hello,

My check engine light keeps coming on. My mechanic says it's sludge that needs to be cleaned out, but they would have to tear the engine apart. Does anyone know of a simpler way around it? Like an engine cleaner?

Hi,

We have a 1998 S40 2.0i and it's been a top performer over the last few years. However we were swapping the position of the cars on the drive earlier this evening and when I came to move the Volvo it just would not engage reverse.

You press your foot down on the clutch and the pedal is very floppy. You try and enter reverse and it just grinds like you haven't...

Hello All,

I have both read and posted previous messages about a Check Engine Light caused by a coolant error. I took one posters advice and purchased a Wahler thermostat. I now have two questions: (1) could someone give me quite explicit directions on how to replace the thermostat myself (2) tell me where and how much I can purchase a sensor?

Thanks much in advance!

Hi all - new guy here.

I have a 1999 S40 which has developed over the last couple of days an annoying idle problem. Today it got so bad that everytime I stopped, the car stalled. RPM speed does vary but car usually sits around 450/550 RPM. Lately its been jumping from 200 up to 1000 and it gets worse when I brake.
