#235 of 291 Start Problems, CCM? by 2003vdub Sep 14, 2008 (5:07 pm)
Hi,   I have a 2003 Passat V6 MT. Here is the situation:   1.Wednesday: Wouldn't turn over- just the click click of the starter. AAA gave me a jump; started right away. I then drove aimlessly for half an hour trying to charge the battery. Got home, parked; tried to start again, no luck. 2.Thursday: Got another jump and drove to the shop, where they checked the battery and said it wouldn't hold a charge. New Interstate battery; also, changed the cabin air filter while they were at it. Drove around a bit, made several stops. No issues after new battery. 3. Friday: Ran a few errands, no issues. 4. Saturday: Went out for a few hours, on the way home the instrument panel started flashing random fault lights and beeping at me. Pulled into the driveay and turned off the engine. Immediately tried to start the engine and it is dead- this time not even the click click of the starter. No accessories working, very dim interior lights only. 5. Sunday: Wake up, try the car and it starts no problem! Go to the museum, get in the car to go home and click click. Got a jump and drove it straight to the shop, where it is sitting because it is Sunday.   Sorry about the lengthy description. Here are some thoughts.   1. If there was an issue with the alt and the battery was not being recharged, I probably wouldn't have been able to start the car this morning after a seemingly very dead battery yesterday. 2. It has been a very dry summer in MN, but raining these last few days. 3. I do recall at some point seeing some water in the trunk, sort of made a mental note that it was odd and then forgot about it.   So I have been reading all the informative posts and noticing a trend with the fuel control module and the CCM being affected by moisture...thinking is it a coincidence that the problems of the last 2 days occurred on rainy days?   Any thoughts would be much appreciated!
#236 of 291 Flasher Relay problem by homeall Sep 25, 2008 (2:31 pm)
My turn signals and emergency flasher are not working. I am convinced that the flasher relay needs to be replaced. After searching in vain to find the location of the relay I went to the dealer to buy the flasher relay. It turns out that the emergency flasher switch and relay are one unit. My problem now is I don't know how to remove the dash panel in order to replace the the flasher. I tried removing the glove compartment thinking that I can get access to the back of the relay but I could not even get my hand in there. Can anyone tell me how to remove the dash panel? Or is there another way of replacing this switch (without going to the dealer)? Replies to this message: ramonago (Oct 04, 2008 7:25 pm)

Replying to: johnrbek (Aug 25, 2008 12:34 pm) To: johnrbek THANK YOU. I found the fuse you described - it was blown - replaced it, and everything works... except... following my installation of a replacement fuse, I started the car (successfully), then turned it off and exited the car. Used my key button to unlock all the doors, and went to put some tools away. Within a minute, the car beeped all by itself, and all the doors were locked! I tried this three times; car will not stay unlocked for more than a minute! Soooo, the underlying problem causing the blown fuse is still out there. But, again, thanks - you have saved me mucho mula. Replies to this message: homeall (Oct 02, 2008 1:45 pm)

Replying to: rick120 (Oct 02, 2008 1:26 pm) The Jetta's and Passat's have a security feature that when you unlock the door/s and then don't actually open the door/s the car automatically locks itself back after a few seconds. I believe this is to protect you from unwittingly unlocking the door/s as you walk away from your car leaving your car vulnerable.

Replying to: homeall (Sep 25, 2008 2:31 pm) My dad just found a website that describes the replacement process step by step (my mom's car is doing the same thing). He found it at ehow.com. I noticed that Recalls had been instituted for the same years of cars for Volkswagens GTI and Jetta. And just like the Passat, the relay and Hazard Flasher were one unit. One would think that VW would be willing to replace this as well since NHTSA considers turn signals a safety item.
#240 of 291 2007 Passat - electrical Issues by tigerroars Oct 22, 2008 (6:43 pm)
My Passat randomly turns on warning indicators i.e. door is open, airbag fault, steering wheel fault, low tire pressure, etc. When this happens the doors lock and the car will not unlock. If i shut off the car, it will not restart. In 1.5-2hours the car resets itself and is fine for another 3 or 4 weeks. The dealership says their are no fault codes. Is anyone else having this problem?
#241 of 291 Fuse question by vwp2000 Oct 23, 2008 (7:36 am)
Hello,   This morning, I tried to unlock my car but to no avail. I tried to start it and nothing. No lights, either. Basically it was dead. I just got a new battery so I'm pretty sure it's a problem w/the fuse as discussed.   So, I opened the fuse box to see which one was blown...the only question is how can I tell? They all looked okay. I'm assuming they look like a light bulb when they burn out, but I'm probably wrong. Need help. Thanks.
#242 of 291 Volkswagen Passat electrical issue by rockman1020 Nov 17, 2008 (12:12 am)
Just replaced the blinker switch on my steering column this week. After switch it out. I realized that now the blinkers and windshield wiper both don't work. I believe that I probably blew a relay of fuse. The fuses are all fine but where is the relays for the blinker & wipers? Are they both run off the same relay??

Replying to: rockman1020 (Nov 17, 2008 12:12 am) Thought it might be battery, so took it out (it's a new battery). The shop recharged it so now I'm thinking...alternator? Maybe the alternator drained the battery.

Replying to: rockman1020 (Nov 17, 2008 12:12 am) I am not sure where the wiper relay is but the turn signal relay is incorporated with the emergency flasher switch on the dash (at least on my 2000 Passat). I had a problem with the turn signals and could not find the relay switch. I just went to the volkswagen dealer and ordered it. Turned out the 4-way flasher switch and turn signal relay is one and the same. Just order the wiper relay. Once you have it you will know what to look for. However, the two relays going bad at the same time is highly unlikely. There may be another problem.
