I recently had a rough idle problem with my 02 passat w8. I took it to 2 places both confirmed a cam position sensor code and miss firing in bank 3. The dealer told me that the car required a cam position tensioner and a related gear. The job would require pulling the motor and included an extensive new parts list. The car has about 105k and is out of warranty. The dealer wanted $7500 for the job.
Is this a common problem with the w8? And what is a reasonable price to fix it?
thanks.

semi-common, we had quite a few of these come in. prob'ly an average price. we usually saw them with a torque converter fault too, so check the TCM for faults. then it's about a $12k job...

Re: W8 rough idle faulty cam position tensioner (David R. Hendrickson)

I've heard that there is an improved cam adjuster actuator housing being installed when these jobs are done. I'm told there's a oil screen in the unit that is known to deteriorate on the originals, and has been upgraded.
The adjuster housing part numbers (7D0 109 210 & -204) ending in -D have been superceded by ones ending in -E... maybe there's some truth to the rumor?
Do you know anything about that, David, (or anyone else?)

Re: W8 rough idle faulty cam position tensioner (law128)

i just replaced timing chains and cam tensioners in a w8 a few mognths ago. 7500 is not insane for that job. the one i did was unde warranty and it was just over 3000 for all of the parts at warranty cost. not gonna lie i really don't want to have to do another one for a very long time.

no kidding. didn't know there were that many around here. are you some kind of W8 guru? i'll make sure to call your shop when mine takes a crap. are you at d. harrison? or better yet an indie who appreciates an extra pair of hands and good burbon (after hours)...

im the only one who would touch a w8 at my shop. i work at jim ellis vw in chamblee. every w8 will eventually need this done. but it seems the new parts fix the problem though....hadn't done one twice yet.

Re: W8 rough idle faulty cam position tensioner (sedro)

I had the rough idle problem too and had misfirings. VW dealer is going to replace the timing chain, case and tensioners. I have been quoted over $8000 for the job (over $5000 alone for parts). I bought an extended warranty but they're stonewalling me. It should be covered.. I guess i'll know in a couple days. wish me luck.

By the way, I also had the torque converter problem too. Luckily that one failed @ 54,400 miles (600 before the powertrain warranty was up), otherwise they said it would've cost $2200

W8 passat timing chain

I was wondering if the timing chain tensioner housing can be replaced without removing the engine on a 2003 passat wagon W8 4motion?

Big props to jim Ellis vw . About 6yrs ago my buddy's syncro diesel wagon snapped a couple wheel bolts . Jim Ellis vw totally helped out . We were on route to SOWO from ottawa . Good guys 👍. I seem to remember seeing a w8 with it's trans out.
