#3223 of 3341 Need Help from Korea!
Apr 03, 2011 (9:49 pm)
I'm still stationed in Seoul, Korea and still own the 2003 VW Passat GLS 1.8T. Recently, I've noticed an extra vibration and a low humming sound when I turn the steering wheel at low speeds. It's okay in the morning, but as the car warms up and when I try to steer the car at speeds less than 5 mph (in the parking lot especially), I've noticed occasional humming sound accompanied by a little extra vibration in the steering column.
Additionally, I've noticed sporadic rapid ticking sounds (akin to fast water trickling sound, but more distinct) coming from the middle ventilation vent. I've initially thought it was some kind of water leakage, but could it be somekind of lifter or ignition coil sounds?
The car currently has 49K miles on it and am ordering parts to replace the timing belt and water pump, but am not sure what else need to be addressed on this car.
Thank you for your advice.
#3224 of 3341 "Brake" warning light -- 2000 passat
Apr 04, 2011 (4:56 am)
Appreciate any insight/suggestions.
The other day "brake" warning on my dashboard display started flashing for quite some time, together with the ABS warning signal coming on and "see service manual" messages. Stayed on the entire time I drove. The next day, nada. None of them came on.
In the previous few weeks, for one or two seconds, about once a week, they came on annd then stopped. Car braking handled normally.
Think it could just be the sensor? Will take it in to the shop for a diagnostic and repair but would like a bit of an idea of what I'm heading into. Love the car but at 114k miles, something needs fixing every month and it driving me nuts.

For what it's worth my 99 Passat exhibited the same symptoms, although my tachometer also stopped working in tandem with what you describe. It started out intermittent, but eventually the behavior became 100% consistent.
Ultimately, it was the ABS controller that needed to be replaced. Somehow it was electrically affecting the other displays, as replacing the ABS controller fixed the other symptoms.
The dealer originally wanted $750 for parts and labor, but agreed to fixing it with 1 yr warranty for $500.
These cars get very expensive after 80K or so.

Navy Guy: Humming, vibration, ticking? Any or all of these MIGHT be signs of deterioration/failure of the CV joints. Not normal for a V-dub with 49k, but being 8 years old, you should check the CV boots for failure. If they're cracked or torn, the joints may be been contaminated with grit and water, causing the joints to fail. If you are a DIYer, it's not a difficult job...you can obtain both joints on line (Rock Auto, Autohaus AZ, etc.) for less than $175-200. Check all the prior posts for instructions and tips. One other question...why are you replacing your TB at 49K? ALWAYS good to be cautious with the V-dub TBs, but I'm thinking 75-80k, not 49. One other thing...you probably already are aware of this...be ABSOLUTELY sure that you (or your oil change guy/gal) is using only, I repeat...ONLY, 502.00 spec VW-approved oil, e.g, Mobil 1 0W-40) in that 1.8T, or you could have major probs down the road! Good luck...VW Dawg

Thank you for your advice.
1. Timing Belt: As far as the TB, I'm being cautious because the car is 8 years old and although the mileage is relatively low, there has been alot of short drives (numerous 2-3 mile trips). Besides, I'm trying to take advantage of cheaper online parts and leverage the cheaper labor charge in Korea.
2. Humming and vibration: It's coming from the steering column when I'm turning at very slow speed in the parking lot, and it almost always happens after the car warms up. Still think the the CV joints?
3. Ticking: The sound comes from the center ventilation duct and almost sounds like a more muffled pebbles (small rocks) being slowly being poured into a plastic can or water trickling sound. It has no rhyme or reason to it. It usually happens after hard accelerations.
4. Motor Oil: The previous owner used Royal Purple synthetic and for the past three years that I've owned the car, I've used Mobil 1 0W-40 synthetic.
No engine problem so far, but I'll keep my finger crossed.
Thank you again for your note.

#3229 of 3341 Fan behind radiator drains battery. VW Passat 2.0T 2006
Apr 11, 2011 (7:47 am)
I have a 2006 VW Passat Sedan 2.0T. My radiator fan keeps running endlessly after my car is turned off. It had drained the battery. I have since got a charge in the battery and now the car is sitting idle with the charge taken off. I have looked endlessly for manuals on where to locate the relay to see if that needs to be replaced (no luck). I am looking for a solution so i dont have to unhook the battery every time I stop somewhere. I dont mind taking it to the shop, but they have already quoted me a couple of hundred dollars for what I see is a easy fix. Just trying to see the option of locating and replacing the relay myself (if that is the problem). Is there any help for this issue?

The fan is allowed to run for up to 15 minutes after the engine is shut off. So anything under 15 minutes is normal, and if your battery can't handle that, then the battery or charging systems is substandard.
if it runs longer than 15 minutes---what I'm seeing in the database is that there is an engine temperature sensor located in the upper coolant lines (diagram is a bit vague), which should be tested, and there is also a Cooling Fan Control Module, which is integral with the cooling fan itself and must be replaced as a unit. Diagnosing that is probably something you can't do without proper equipment and instructions.

Navy Guy: Nothing wrong with being conservative here, especially if lower labor and parts costs are available. I just changed the TB on my '02 1.8T Passat at 92k...obviously taking a chance there. Do you use a good independent shop that might be able to inspect the existing belt for crackling or fraying? In any case, at 49k, and if the car is otherwise in good shape, for your peace of mind maybe just go ahead and get it done.
Humming, vibration and ticking...tough to comment without actuallly hearing the noises, but still think it could be CVs or something else in the front suspension. Get it up on the hoist and inspect thoroughly. Good to hear that the prior owner used Royal P, and that you have continued with Mobil 1. I seriously doubt you will have engine probs under that scenario, but check the prior posts concerning new info on VW finally getting their act together on warranties against sludge & other oil related issues. vwdawg

Can anyone tell me when the timing belt should be replaced on a 2008 Diesel Passat, I have spoken to Volkswagen but they just tell me to talk to my dealer
