#227 of 489 97 Passat GLX sedan, mystery oil loss and shifting.
Jan 15, 2008 (12:13 pm)
Hi, I have a black 1997 Passat GLX sedan, 6 cylindar. I bought this car six months ago from the local VW mechanic. When i bought the car it shifted a little bit hard, but other than that, no problems. The person who owed the vehicle before me had put around 2 grand into the transmission, it would not work right. She had taken it to the VW Dealership in State College, PA, and got tired of throwing money into the car and sold it to the guy i bought it off of. He put a new transmission in it, and fixed a few other things before selling it to me.
Now soon after I bought it, my car began slipping gears. It got so bad I had to shift manually. It was never in the right gear, sometimes it would pull out of an interesection in 3rd gear and just dog along. I discovered the only way to make my car run correctly, was to floor it. As odd as that sounds, every time I floored my car it stopped slipping gears, stopped slamming into gears, and ran fine. I no longer had to manually shift it. So i thought I was alright.
Well about a week ago my car started doing something else. It stopping shifting right altogether. It wouldn't go out of first gear until (according to the RPM gage on the dashboard) it hit bewteen 40 RPM's and 45 RPM's. But it has quit slipping gears. Then between 2nd and 3rd gear, it wouldn't shift until it hit around 50 RPM's. Even then it was sometimes a fight to get it into 3rd. The ONLY way to get it to shift is - you guessed it - flooring it. Once I did that it would go into the right gear, and not mess up, and continually shift correctly until I stopped the vehicle.
Now the computer in my vehicle was thinking that every time I hit the gas on my car, that I was flooring it. When I actually did put the pedal to the medal it seemed to override that and run properly. It got continually confused, sometimes on my dashboard all the gears would highlight like my car didn't know what gear it was in. Also, when i pulled out from places or headed uphill, it would jerk forward and back for a few seconds until I floored it. It was explained to me that this computer thought I was hitting the brake and gas at the same time to cause that effect. Now my mechanic has replaced this computer, which resolved some of the problems, but my car is still not sure what gear to go in or what gear it is in.
Also my car is suffering from a mystery oil loss. I have to add about a quart every 2 ro 3 weeks. It is not burning any (nothing coming from the exhaust except in extreeme cold weather) and not dripping anything (I keep a close eye on it and have had my mechanic take a look at a few times).
It has stumped me and everyone else I know.
Has anyone else had this problem or one similiar to it? Or perhaps know what could be wrong? I appreciate any response!

I have a 2006 Passat 3.6 that, for now, the oil changes are being done at the dealer. I am tired of paying $80 for it. Yesterday I went to the dealer and got a filter and 7 quarts of oil. They use Castrol Syntec SAE 5W-40 that has "specially formulated to meet the needs of BMW, Mercedes-Benz, and Volkswagen." On the back it has VW502 00 and 505 00 as well as standards for Mercedes-Benz and BMW. Also states "Offers full synthetic performance specifically to meet the Volkswagen engine warranty requirements, including testing in VW TDI engines." At $6.44 a quart at the dealer I hope to find a better price.

What specs must you meet with the 3.6 engine? You might want to investigate whether Mobil 1 Euro formula (0w-40) fits your needs. It will definitely be less expensive than the dealer's Syntec at regular prices and even moreso when on sale (although that seems to occur more rarely these days).

Our local AutoZone sells both Mobil 1 0W-40 and Castrol Syntec 0W-30 for less than $6.00 per quart. Both oils are significantly more robust compared to the oil you just bought because not only do they meet the 502.00 gasoline oil spec, they surpass it by meeting the VW 503.01 spec. FWIW, 505.00 is for Diesel engines, and both of the two oils I mentioned are certified to meet that spec as well.
FWIW, the Mobil 1 oil can also be found at our local Walmart as well as many of our local NAPA dealers.

I have a 2001 Passat 1.8t with an oil pressure / sludge problem, so I was browsing these posts. I found this post that might help with the transmission problem... http://forums.fourtitude.com/zerothread?id=3471982
I hope this helps..
As for my oil pressure / sludge problem I have chosen to try the Auto-RX cleaning procedure. http://www.auto-rx.com/pages/heavy_sludge_app.html
FWIW... This oil pressure / sludge problem has manifested itself in a cam chain tensioner indicator code in the computer and a dash oil light on a few occaisions. VW wants to replace the Cam Chain Tensioner, a $900 repair. I figure the Auto-RX solution (about a $60 endeavor) was worth a try.

While you're not going to lose much by giving the Auto-RX a try, I seriously doubt that that stuff will even put a dent in your sludging problem. Assuming that you get little or no benefit from the treatment, your best and cheapest remediation measure might be to have the cylinder head, oil pan, and oil pickup pulled and cleaned. With those our of the way, you have a pretty good chance of keeping your engie running for quite some time yet (assuming that you use a good VW approved oil and change it OFTEN).
Keep us posted.

I have a 2003 VW Passat, 1.8 liter turbo. I got a low oil warning ("Low Oil Pressure: Stop Now"). Anyway, my car has 95,000 miles on it and it is 5 years old.. still VW fixed the "slug" issue for free.
I was told that the the VW 1.8 turbo's heat will slug the oil as there is no after oil cooler; moreover, the oil pan is too small to allow for adequate heat dissipation. The best prevention: don't skimp on non-synthetic oil (use recommended oil--see manual) and have the dealer run a cleaning/deslug procedure ever 20,000 miles (about $100). The synthetic oil should be changed at 7,000 or when it gets dirty looking (dark), which ever occurs first (my experience is about 5,000 or 6,000 miles).
The fix: The dealer checked for cam and crank wear, saw none... and cleaned/replaced the oil pump pick up screen. Then ran some sort of approved solvent/oil mixture through the engine to clean it and changed the oil twice. The total bill was about $650, but VW's warrantee took care of the bill.
I believe it is well worth the effort to keep the engine running clean and correctly. Afterall it is a well performing vehicle, otherwise. Also, note that the mechanic said that the engine has such low tolerances that it is best to use the oil specified to ensure low engine wear and problems. Do not use cheep oil, for your own good.

I'm not sure where you get your information from, but 7,000 miles in a 1.8T, even on the best synthetic oil, is waaaay too far. Per your manual, 5,000 miles is the maximum oil change interval, and not just any synthetic oil will do as only oils that are certified to meet the 502.00 and/or 503.01 VW oil spec should be used.
Regarding how oil looks, its relative darkness is completely irrelevant, there are plenty of used oils that are as dark as coal that are still extremely serviceable where there are other used oils that are as amber as honey that are completely exhausted. The only way to know for sure of your oil is holding up is to have it analyzed.

It looks like a mix of some truth and plenty of misinformation.
Like shipo wrote the max OCI is 5000 miles. The oil MUST meet VW oil spec 502.00 or, if you are really crazy, newer 503.01.
No car should require regular desludging.
PS I have Subaru Legacy GT (the one with turbo engine). Subaru started with 7500 miles OCI but recently changed spec for newer cars claiming that all turbo engines should be maintained per severe service schedule (3750 miles OCI).

I too have been a victim of Volkswagen's neglect and VW not standing by their product. My car has been in and out of the dealership since I purchased it NEW. Over and over again, oil is disappearing and not in the car at all. Several times I have had to stop my car immediately and have the car towed to the dealership because I could not drive it due to no oil in the car. The engine light went on and specifically told me to "Do not DRIVE". This is absolutely absurd with a new car. I would not recommend a VW to anyone. They are highly unreliable and unsafe as far as I am concerned. Buyer Beware!! VW will not stand by it's product. I have repeatedly gone to the dealership to have this repaired, but the same problem keeps coming up over and over again. VW will not do anything for you. Please save yourself some problems, do not buy a VW as they continue to be out for themselves.
