i have a S40 T4, and have had a software upgrade done on my car. i have read that i should upgrade my diverter valve to avoid any problems that might occur due to my software upgrade.

what are the facts behind this? should i change my diverter valve or should i keep it as stock and fit a dump valve instead.

Also, how do i go about...

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.

My car is at the...

Hi!

My center console lights are out. I have checked my fuses and all are fine so I started to take apart the center console. I got everything off except the plastic piece with the gear indicators on it (it surrounds the gear shift) anyone know if it comes off, or where those bulbs are located? I have a 2003 S40. Thanks in advance!

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...

In the past 2 days my car began having starting problems. When it sits overnight and I try to start it it just keeps cranking for a long time. When it finally starts it stalls right back out. It takes me about 2 minutes to get it running, and when it does run I have to keep it reved up for a minute or so until it clears up cause it sputters like all hell. Once I get it going it runs great as...

I have a few minor problems that I could use some help on...

First, my headlights seem to be adjusted too low. I know they can be adjusted, but I can't figure out how to. I think there is a screw?

My gas gage and trip computers calculation of fuel left seems to be erratic after about 1/2 a tank. This is only a nuisance to me since my OCD causes me to want to top off just...

I have two questions. Does anyone know if the 2001 Volvo S40 1.9t already has a Blow Off Valve on it stock. And my other question is if there is a stock BOV already on it, do I have to take that one off first before i put an aftermarket one on?

Hello All,

I have noticed a few things with my newly purchased used Volvo (2001 S40, 66,000), namely: at stoplights when ideling it sometimes surges/jumps; when ideling in reverse it sounds rough and recently spit out moisture from the tailpipe; sometimes when trying to accelerate quickly it revs too long before switching gears (it is an automatic). Some things to note, I have filled...

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.

Have had this problem before and the main dealer replaced...

Hi Everyone i'm new, Just bought myself a Volvo S40 and was wondering when the timing belt should be changed, so far the car has 46,000miles on the clock.

Hello

I need some help. I have a Volvo s40 1.8 xs W reg year 2000 and the fog lights don't work front and rear. I have replaced the light switch with the correct part number as I was told by Volvo Dealer. Checked the fuses and they are ok. My car doesn't have a relay switch to change so am not sure what else it could be. I don't get any lights on my dash either to say that...

Help! I broke my power antenna and the car wash and ordered a replacement. Step 1 says to remove the nut the is holding the mast in outside of the car. The nut turns and goes up the bolt it then gets near the top but will not come off. It just keeps turning and turning while it stays in place. Is there a trick to getting this nut to come off so I can remove the old mast?

My volvo headunit has died & I'm looking to replace it with a Sony Headunit - the only problem is that my S40 has an external amp. Has anyone replaced a headunit & cut out the amp? If so can you please offer some advice?

I have a 1999 2.0 T SE S40 that runs great considering the mileage but pulls very badly to the left.

I have been trying to get to the bottom of this for some months so there is a lot of background. Apologies in advance therefore for my long first post.

Although I can't remember exactly when this started to happen I do know it's been going on for some time (6 months...

Following bad idle/cutting out problems with a UK '99 S40 T4, the ECU is currently under diagnostic testing but the problems may also be caused by a sticking EGR valve. However this is proving difficult to track down on this particular vehicle - can anyone please confirm that the UK T4 specification does include an EGR valve and if so, where it is located? I realise this may be under the...

my engine management light wont go off ive taken it to a garage and they are saying nothing is wrong with the car but i have noticed a considerable difference in the acceleration of the car does anyone know anything that it could be???

I have a puzzling question......My 2004 LSE with 70,000 and good tires has developed a wierd problem....at low speeds, the steering wheel will turn itself left and right at least a quarter turn in each direction on it's own! At higher speeds it's not as noticable, but still present.

Soe people have told me it could be a speed sensitive steering issue, some say it's a...

Hi all, i am wondering if you can help me out. I need to know how to remove the door ding gaurds(or the trim on the doors that is black) to get them color matched to my car? thanks

Hello All,

I also have a check engine light on. I took it to a mechanic near me and he used a diagnostic tool that gave P0128 (coolant temp too low) error code. I called the nearest volvo dealer and told him this and he said the code means nothing since certified volvo mechanics have a specialized tool and the code I gave him was irrelevant. Is this really the case? I read the thread...

I found an MAF on eBay for the 2000 S40. Does anyone know if it will work on the 2001 model?

Anyone seen this particular combo. Had a bit of a hassle passing state inspection last time and was told I had a coolant temp problem - came up as 0128. Don't even get me started as to why a vehicle could fail a state (NH) safety inspection due to a slightly out of range coolant temp. What the hell ever happened to "Live Free or Die"?!! Bunch of ...

hello everyone,

i have a question about the difference between the T (160 hp) and the T4 (197 hp) versions of the S40 from the 2001 model. if i've driven a turbocharged S40 (with automatic gearbox), and there has been in it a button that increases the turbo compression and makes the performences much better - does it mean i've driven the T4 version? or maybe both versions has...

hi, I am wondering if anyone has experience installing the exhaust system Eurosport Tuning offers for Volvo S40's (2001-2001) or anything similar to it. If so, can you please tell me if it was hard to install at home; or if this job should be done by an actual exhaust or auto garage. If this installation should be done at an auto garage or exhaust shop, around how much do YOU think it would...

Good Afternoon All,

This is my first post after visiting several times to look for answers.

My situation is this: I am changing the plugs on my 2003 S40 for the first time. (Thanks to other posts, I was able to locate them and know that I needed a T-30 socket to remove the cover!) However, when I removed the original plugs, I noted a 5 digit designation on them: R6...

hope someone can help me..my heater/air cond controls don't work such as the fan control. I have checked the fuses and they are ok. I didn't know what else to check to locate the problem. Possibly a relay???? your help is greatly appreciated

Hi guys,

perhaps some of you already replaced your turbo units and will be able to help... I am looking for a replacement turbocharger for my 2003 S40 T4. My engine type is B4204T5. Can anyone tell me the right part number? Or will any S40 turbo unit fit? I know only that there is a high pressure twin scroll one and a low pressure one but that is all...

Cheers

I filled my tank up last weekend. I have put 90 miles on since the fill up. I currently have 1/2 tank left. This is not normal. Any ideas what may be going on?
I drive to and from work, highway 20 miles round trip daily.

I am running a little low on antifreeze. (New volvo owner) I noticed that there is a sticker that suggests to use "Volvo" formul antifreeze. Is this a must or will a good high quality alternate brand suffice? My nearest dealer is 3 hours away. (tough to get parts and service)

Hello all, I just bought an 02 s40. As far as i know in the u.s. you could only get a 1.9 t engine. I cant figure out what type of turbo they came with, I assume the t2 but was hoping someone could clarify. Thanks. cheers

Hi there,

New to the forum so thought I'd just say Hello to everyone right off the mark.
I have a 2001 S40 Sport 1.8. Excellent car, love it. Although, I'm here to learn so... Anyone wish to share any things I should look out for while its in my ownership?

Any info would be greatly appreciated.

Trying to clear a "Check Engine" situation.

Most recent state inspection revealed a discrepancy between the coolant temp and the OEM thermostat spec (192 F I believe). I have learned from this forum that the code was most likely P0128 - I didn't ask. Anyway they cleared it for me and I was not overly concerned. However, my wife, who drives this car on a daily basis is...

i've got these black channel like parts that have come unglued from somewhere in/around my sunroof. the curved one came out today, its been clanging around the front of the sunroof for a couple of days. the straight one's been sitting in my trunk since it came out last year. that one was clanging around the rear part of sunroof....

Hello All,

While backing up, I hit a post and cracked the back passenger side tail light. I could just take it to the dealer and have them buy the part and replace but I am guessing the cost on that would be through the roof.

My second option is buying a new (quotes at about $125) or used (quotes at about $75 + shipping) piece online and having my local mechanic...

Hello all, this is my first post (probably of many)

does anyone know (without cutting through the lid) how I can open the bonnet.
The release lever in the car is loose when you tug it, so the cable must have become detached from the opener at the bonnet end.

I have tried pushing my arm under the car and moving the release lever, but this does not work, no matter how hard...

ac blows out cold air but when you turn the dial above 2.5 the dashnoard rattles and shakes. Also the auto function doesnt work anymore. anythoughts as to what it is before i take it into a service station?

I have aticking under the dash of my s40 thtat is related to the A/C some how. Depending on what buttons on push o hte A/C or air flow directions, I can make it start or stop. Any ideas how to fix jit?

Ok the dealer said that my suspension sway bar/bushings needed replacement ($430 quote). The bushings are rubber, I understand that they would wear down over time. He stated that the car is pulling left a bit and it could be an axel problem, could be suspension sway bar/bushing, etc. BTW, the car is making no noises in regards to the suspension. I'm thinking this is an early sign but...

Hi, I just found this forum, which hopefully will help me to solve my bonnet problem
I'm from Austria /Europe and I hope my english is good enough to understand what I tell you.

The problem is that my car makes very loud noises when it starts, I think the V Belt should be changed (1K kms ) so I wanted to take a look at it to see if there are any damages on it.

I was just wondering if anyone has the Air Intake System from Eurosport Tuning? I was thinking it might make more power because the factory air-box seems to be restrictive. I figure turbo cars suck a lot of air so a more open filter system might increase performance. It looks really nice in the picture too.

The following link will take you to the item I am looking at.
