#348 of 357 2006 Passat 2.0T - oil question by 17345 Aug 28, 2009 (3:23 pm)
I've been pouring through these posts until my contacts are glued to my eyeballs.... I bought an 06 Passat 2.0 Turbo from a dealership (they'd got it from an auction) with 50k miles. Yes I bought an extended bumpter to bumper warranty. Within the first week of driving it, I got a Service Now and then a check engine light. The dealership where I bought it doesn't have any VW certified techs. Nearest VW dealership is 3 hours away. I took it to a "foreign make" repair place. They attempted to run a diagnostic and could only say they couldn't communicate with the engine controller. I took the dealership PDI/UCI form (indicating they did a 50k check, oil change ect) to the VW dealership 3 hours away. They ran a diagnostic, said the engine was showing a low-voltage reading, asked if someone had disconnected the battery. When I said I didn't know. They cleared the error, drove it for 8 miles and deemd it "fixed". That afternoon the Service Now message displayed and the next day the check engine light came on. Everyone kept asking me "is it running fine? If so, it's not an emergency". So I drove it one weekend and stuck in traffic, running just above idle and the car was WHINING. (I was in Sport mode) Ug. Finally figured out it was MY car. Drove it all the way home. Can't get it to recreat the whining now, but I finally found a place in town that has techs that are newly VW certified. I explained my two issues - the service advisor thinks the oil is the issue with the whining. That the dealership might have put in the wrong oil. Upon confirmation, it's true - the went by what AllData told them - 5w30 if 5w40 wasn't available. Nothing said about synthetic! And no the car didn't come with a manual. The service advisor at this new place said to use 505.01 Pentosin. I did some research and it looks like it's only for diesel engines. Mine is not.So I called her back and she said they've been using it on ALL VW and Audi's, Turbo, Diesel or Gasoline. Just clear across the board. In the meantime the dealership where I bought it scrounged up 5 quarts of Castro SLX and are replacing the oil as I write this. (Who were told that VW was switching to Mobil as the preferred synthetic oil).   I'm frustrated. I can't find a flippin' manual. Everyone keeps giving me a different answer. I don't know if my two issues are related. Monday I have an appointment for the check engine/low voltage reading. I sorta half thought the whining might be the alternator slipping which could account for the low voltage reading, but the belt seems fine. Ug. Any thoughts?   Sheli Replies to this message: lserve (Aug 31, 2009 7:49 pm) vwdawg (Sep 01, 2009 10:20 am) shipo (Sep 01, 2009 11:05 am) altair4 (Sep 01, 2009 11:11 am) and 1 more...

Replying to: 17345 (Aug 28, 2009 3:23 pm) Can't help on the diagnosis, but the vw dealer who services my '07 only uses Syntec 5-40, which is one of the approved synthetics. It indicates made for VW on container. Commonly sold at Pep Boys, etc.   Good luck!

Replying to: 17345 (Aug 28, 2009 3:23 pm) Hello, 17345: Not wise to use ANY oil that is not on the VW-approved listing (I believe altair4 posted the actual list a couple of months back, so check it out). Also wanted to respond to the comment on Alldata's alleged advisory that it's "OK to use 5W-30 if 5W-40 is unavailable". That advice is, I think, directly from certain VW manuals (my 2002 Passat 1.8T manual, for instance). HOWEVER, there is one critical part of that advice that is missing, and that is that 5W-30 is ONLY OK for TOPPING up, and only when 5W-40 in unavailable, not for actual oil change applications. Seems to me that there IS one 5W-30 that is approved (Syntec European Formula?), but can't recall which one. Good luck, but proceed with caution! vwdawg Replies to this message: shipo (Sep 01, 2009 11:05 am) altair4 (Sep 01, 2009 11:11 am) shipo (Sep 01, 2009 4:06 pm)

Replying to: vwdawg (Sep 01, 2009 10:20 am) Common VW 502.00 oils available in the U.S.:    - Castrol Syntec 5W-40  - Castrol Syntec 0W-30  - Mobil 1 0W-40   All three are acceptable for primary use during an oil change as well as for topping off in between oil changes.   Best regards, Shipo Replies to this message: altair4 (Sep 01, 2009 11:11 am) shipo (Sep 01, 2009 4:06 pm)

Replying to: shipo (Sep 01, 2009 11:05 am) Shipo, maybe you know the answer because I don't, but what is the VW Spec for the 2006 2.0T? That's what the original poster has. I know 502.00 was okay for the previous gen Passat. Not sure if that applies to the B6 version. Replies to this message: shipo (Sep 01, 2009 4:06 pm)

Replying to: altair4 (Sep 01, 2009 11:11 am) Yes, in the States, VW 502.00 is specified for both the FSI (through 2008.5) and the TSI (2008.5 and later) versions of the 2.0T.   Best regards, Shipo
#354 of 357 W8 Passat by dcolosimo Oct 04, 2009 (6:17 am)
I bought a 2003 w8 Passat in 4/09 with 48000 miles. The other day I started the car and it was missing bad. Took to dealer codes for misfire cyls 5,6,7,8 and cam adj advance. Dealer seems lost on W8. Says he has to take engine out. My warranty won't pay saying they believe it is a sludge problem. Dealer wants to flush motor. I have complete history since new and car has always been serviced. Any knowledgeable people out there on W 8 with any answer and how do I get my waranty company to cover repair?

Replying to: dcolosimo (Oct 04, 2009 6:17 am) Realizing it may have been serviced timely, but what oil type (synth or regular) and grade was used? In other words, was it completely compliant with VW's specs? That might determine whether it was sludged or not.   Did you buy the car from a VW dealer? Was it CPO?   Also, bear in mind that the W8 was a fairly rare engine for some dealers. Not all of them are conversant in problems with that engine. You might want to consider having another service department look at it.   At the very least, post the codes that the engine gave through the OBD.   Oh, and who is the warranty company? You might save someone else from dealing with a difficult provider. Replies to this message: dcolosimo (Oct 05, 2009 9:27 am)

Replying to: dcolosimo (Oct 04, 2009 6:17 am) dcolosimo: Wow, what a horrible mess. I agree with altair4...get a second opinion from a either a good independent repair shop or another dealer. Sludging at 48k sounds pretty outrageous, and if VW-approved synth was used, then VW should definitely be covering this regardless of mileage...contact VW America to complain. I think the extended sludging warranty runs ten years if you are using the correct oil. And, why do they need to take the engine out to de-sludge? Is that the normal procedure for that? Good luck. vwdawg

Replying to: altair4 (Oct 04, 2009 3:48 pm) Thanks for your reply. The car was serviced by a VW dealer in Rochester, Ny since new. I purchased it from the original owner with a complete service history. Oil has always been approved synthetic and even when I changed it the shop used synthetic every 5000 miles. The original dealer is aprox 150 miles from me so the VW dealer I took it to is about 100 miles. I did call the original dealer 4 times and have yet to receive a call back. The codes I have are 16406 bank 2 cam adj adv, 16684 random misfire, 16689 cyl 5 misfire, 16690 cyl 6 misfire, 16691 cyl 7 misfire and 16692 cyl 8 misfire. The warranty company is Universal and they were highly reccommended but now I question that. I did call VW and open a complaint and ask for a QTM to be brought in since the dealer didn't seem to be too knowledgeable. I have not received a call back from VW yet either. I love this car but I am sorry I bought it. I am hoping the problem to be electrical or ignition or something other than the $8000 fix they said it might be. Anyone want to buy a mint W8 Passat? Any help would be appreciated.
