#177 of 411 Passat trouble
Jan 28, 2008 (7:51 am)
I have a 2003 VW Passat V6 4-motion automatic. Today, when I started it up for a 2nd time, the ABS light and the caution light both came on. I have an automatic, and it seems to have a problem varying my speed. It usually shifts around 3,000 rpm, and now takes it up to about 4,500, and there is a noticeable lack of horsepower from normal. Does this sound like something is wrong with my all-wheel-drive? Any advice!?

Sounds like limp mode to me. Perhaps caused by the ABS fault.
If you need a ABS controller you might want to look at this site for an ABS controller rebuild. http://www.autoecu.com/ I had them rebuild my ABS controller for my 2001 Passat 2.5 years ago. It cost $250 plus return shipping. They pay for shipping to their facility. I had it back in 3 days and it has performed flawlessly since. They even guarantee it for 3 years.

Wow, that was quick. Thanks man.
I was also considering getting new tires, balanced and aligned, although my tread doesn't appear to be too low. I've heard that on all-wheel drive cars, if your tires are out of alignment, it tends to throw off the abs performance. Do you think this would be a waste of money? I just bought the Passat in July, and have only driven it for 4,000 miles, and the tires don't look too terribly worn.

If you are concerned about alignment, I would suggest getting it aligned. This is a lot less than $250 for a rebuilt ABS unit. If you still have the problem then you haven't really lost anything because your tires are now aligned.
When I had the ABS controller on my Volvo replaced it had to be off the road. I did my own ABS controller on my Passat but I had the Volvo garage do that one. If you plan to do it yourself I would suggest researching if the car can be driven without the controller in it.
#181 of 411 Electrical Probs with Old Passat
Jan 31, 2008 (4:22 am)
Hi, I posted before about electrical probs like electric windows not working/working on their own, remote locking not working etc. and someone suggested it might be the "Comfort module" that has got damp in it. My floor at the rear on the passenger, right, side is very wet like someone else suggested. I had a friend look around but I don't seem to have a "Comfort module". My Passat Estate was built in 1994 and is left hand drive. Does anyone know for sure if this model has the Comfort module and if so, where it might be.

I have been reading posts, and trying not to be redundant in my own post, but... I think I may have CCM problem but not sure, have tried to diagnose/fix but now I'm stuck: 2000 VW Passat, 71K, automatic trasmission
History: Big rain storms 1 week ago. Found 1/4 inch standing water drivers side (you see where this is going). Wet corner near drivers side of sunroof, and flooded sun roof gutters, suggested that water leaked in through sunroof and came down column near rear view mirror and onto floor. Car seemed otherwise fine. Has worked fine for a week, including being driven long and short distances, and multiple errands (on/off/on/off with electrical, engine, etc).
Symptoms: Last night left work, remote key did not work to open car. Opened with key manually. Found that the following did not work: dome lights, trunk release, sun roof, windows, unless they were lowered/raised by using the key in the door, and car would not turn on. The headlights and radio did work. Needless to say jump start did not work. Had car towed home, as was 9pm and did not have mechanic to drop it off at (long story). Found that key batteries dead too (tested w/ volt meter); replaced batteries in case alarm was preventing car from working, didn't help, but needed to be done anyway.
Plan: Mechanic friend came last night and tested battery and all fuses, all checked out normal. Not much else he could do at midnight and not in his shop. Today, after talking to 3 mechanics, determined that CCM most likely problem. Pulled up carpet, located CCM, removed. Condensation found around cable bundles/under carpet and insulation, which are still very damp. No condensation inside box, opened CCM, no evidence of moisture in there. Put heater in car to dry, left CCM open (but covered to avoid dust collection) for several hours. Carpet dry on top, still damp underneath of course. Plugged CCM back in, checked all plugs near where those cable bundles go into car on left, below fuses, to make sure dry and not loose.
Status: ARRGGH! Still won't work! My CCM did not seem wet. Is it possible it's done for anyway? Or is the problem most likely elsewhere? Any ideas for my next steps?

I've been going through the same problems as you. Although it doesn't appear that my sunroof was the issue. After I got the wiring harness good and dry (like 2 days dry) my problem seemed to resolve. This site http://www.headfuzz.co.uk/?q=vw_ccm , if you haven't seen it already, shows a good example of the CCM problem. You might want to inspect the wiring harness pretty well to make sure that the wires haven't corroded through. There is also a computer on the passenger floorboard. I forget what that one controls though. My Passat had water throughout the entire car. So you might want to look into pulling up the carpet on the passenger side and in the rear seats also. Good Luck...I feel your pain!

Thank you! I will try your suggestions, and welcome more from others.
#185 of 411 '98 Passat
Feb 06, 2008 (1:52 pm)
I recently bought a '98 Passat. I noticed the rear defrost and cruise control was not working. I checked the fuses and sure enough there were not any in those particular spots. I replaced the one for rear defrost and now it works fine, however I noticed there is no wiring coming into the one labeled cruise control. I was wondering is there an easy way to take the wiring from another fuse of the same amps and hook it into that one? Or does it sound like there's another problem w/ the cc all together?

I am having similar problems with my 2002 Passat. The car has been "flooded" twice in the past two years. Dealer didn't do much about it, and I didn't have any electrical problems until this week. Problems include power locks aren't working, car won't start until after I turn the key on and off a few times. I use the key in the outside driver's side lock to supposedly lock the entire car only to find it completely unlocked when I arrive at my car after work today.
Any chance I can "fix" the problem myself (or my husband, who is mechanically inclined)?
