What are the most common ailments for our W8s? I'll start the list...please help out and I'll update this original posting with the general consensus...it would be great to capture rough mileage timeframe and cost to repair as well...

1. Tourque Converter, 30K+, $$?
2. Cam Tensioners/Screens, 30K+, $5-$10K depending on one bank or two?
3. Coilpacks
4. Radiator
5. 02 Sensors
6. Thermostat
7. Steering Wheel Radio Controls
8.
9.
10. Seat Heater ( do recalls make the list? this one was a "hot" item for me when my pants started smoking! )

Some items I've had done but are probably not common...Rear Hatch Open Indicator Light failed, Backseat Ashtray broke (not a smoker, but if you bump into it it opens on occasion and one day it just broke), Steering Wheel Controls for Radio stopped working.

Hmmm, maybe this list of "common" doesn't need to go to 10...that would be good news...although #1 and #2 are doozies!

Backseat ashtray is a must! Thermostat as well. Anyone else have the leather on the front of the front seats pulling up? I've had fuel sending unit go out from moisture under the trunk. Also rear transmission seals were shot. What about CV boots?

I've replaced my radiator but coil packs are fine. I got the recall for the seat heaters but never did it since the are nice and toasty in the winter.

W8-specific, or Passat-specific? I think you'd have a tough time coming up with 10 troubles that could legitimately be considered "common" to the W8.

Thermostat for sure (had mine done twice); I haven't noticed rads or O2 sensors come up as problematic. O2 sensors often get replaced during any engine-out work just as preventive maintenance, but I haven't seen many actual faults reported.

Many folks have had issues with the FIS (cluster) display (heat fade), and the steering wheel radio controls not functioning - again, though, not necessarily W8-specific.

I had my radiator and thermostat replaced at about 36k miles.

Take my advice...get that recall on the seats done. A year or so ago I pulled into a restaurant parking lot and my wife said...who's been smoking in your car, there is a big cig burn hole in your seat next to your leg. I jumped out of the car and you could literally see the sparks flying in there. I don't know what the recall process is but in my case, they had to replace the entire seat cover. New leather is nice but it is not aged exactly the same as the passenger. A year or so later and you really can't tell but for a while there was quite a mismatch.

At 95k miles, O2 sensor is my only problem.
Don´t think anything have been changed, hopefully it wont need it any time soon.

I wasn't looking for W8 only...just the things that seem to go wrong on our W8s. This isn't too scientific, I'm just looking for common issues for w8 owners regardless of whether they are common for Passats in general.

It's a good "question"... could form the basis of a solid reference post on "what to look for in a W8" - a question I seem to answer every month or so.

Take the Top 10, and then attach each item to a thread or post that discusses the issue, and possible solutions.

Is replacing an O2 sensor at 95k miles considered a "problem"? Some routine maintenance is required, after all - nothing lasts forever. That being said... what would folks consider to be a reasonable life expectancy for the O2 sensors (pre and post cat)? Does 95k seem premature?

I meant that in a good way, ofcource things brake, unfortunately it´s to expencive for me to be worth fixing, the only thing it does is randomly throwing me CEL, complaining about a catalyst problem.
