    B5.5, 1.8T Oil Pressure = HUGE problems

    Hello,
    thats my first post here

    Ok,
    Its a b5.5 2003 1.8T saloon. I bought it around 3 months ago and maybe 2 weeks ago i was driving home and then STOP! light came on, it said Oil Pressure! Stop Motor! Service Manual! hmmm.... not good... and i also noticed that this light comes on only on high RPMs, like 2500-3000. But it runs totally well, no strange sounds, no rough idle, starts fine , everything is just fine. So, as long as its my first car i didnt want to f##k it up and i went to VW dealership for help, they did a diagnostic and they told me that there is something wrong with oil pipe or pump. parts are cheap - 200$ for all of them, but the labor - they told that it is 8-9 hours of work!!!!! and 1 hour in VW costs 110$, so its 1400$ to fix it!!!! they that i can drive it , but slowly and on LOW RPM ONLY, because it damage the engine and then i will a brand new engine. Does any one here got the same problem? Any advises? Maybe i can just buy those parts and take to my local mechanic and tell him to change those parts? I like my car so much and i dont want it to die

    2003 Passat 1.8T, 205.000KM
    List of parts they told me to buy:

    06B-115-251 PIPE 23.30$
    N-028-222-2 WASHER 3.60$
    06B-145-735-F LINE 161.07$
    058-145-757-C GASKET 6.22$
    058-145-757-A GASKET 6.22$

    And please remember that its my first car and almost dont know anything about cars yet but i want to learn! Thanks in advance for your help!
    Thanks again!
    P.S. Sorry for my bad english.
    P.P.S. Im in Toronto, Canada

    Your first post and its about dreaded STOP no oil pressure warning!!
    The 1.8T is known to have this occur. Usually it is because the engine has a turbo and small volume of oil, only about 4L. The oil gets cooked by the turbo heat into coal like particles. This residue called sludge tends to plug up the oil intake screen. Many who have proof the oil has been changed at the recommended intervals have had this problem corrected by VW for free. Read more. Use the search feature on the toolbar to search for the word 'sludge' Good luck.

    If you have documentation that you serviced the car with the proper oil and oil filters at the proper intervals (ie every 5k), the dealer should fix your engine oil sludge problem under the extended warranty. VW sent out an extended warranty that deals specifically with this issue. Run a search under those terms here (engine oil sludge) to find a plethora of reading material about the subject. Good luck. Let us know if your run into any interference from the dealership.

    So if you did the changes at the dealer, or can produce receipts showing your oil purchases from the time YOU owned the car, it should be covered under warranty.

    WOW, you guys are so smart! You all talk just like that guy at dealership, u didnt even see my car and u already know whats the problem! thats a talent... strange thing is that i didnt see that light today, i drive as usuall but that light didnt come up. And also - is it safe for me/car to drive with that light? i should keep in the garage untill i fix it?

    step@[dartmouth]
    well, i changed the oil and oil filter on the second day i bought it, but i think they will not do it for free, or they have to? Because i asked them about warranty - they said no, because if i would buy it brand new - then yes.


    And also - do i need all of those parts? Or maybe i need something else? and would you trust to go to a local mechanic?
    THANKS A LOT!!!!!

    In the USA, there is a eight year, unlimited mileage warranty extension for this issue. You'd be well advised to see if it exists in Canada, as well. As far as "all those parts", parts are minor in this case - it's the labor. Replace anything even remotely wearable or worn in that area, and most especially any seals or gaskets. Local mechanic - this isn't technically difficult, just messy and tedious. I'd still want a VW specialist, if not a dealer.

    Yeah, thats right, but it only applies if:
    1) You can provide them with all reciepts
    2) You bought your car brand new from VW or bought used from VW

    Non of those apply to me, because i dont have reciepts and i bought it from a used car dealership. So they dont want to do it for free.
    And about the car - is it safe to drive it?

    You should get an oil pressure check. The specs are for hot engine, at which 2k rpm should give a minimum of 36psi for the AWM engine (cold engine reading will be much higher, and doesn't mean anything). The alarm will go off if under ~20psi above 2k rpm.

    Not being on at say 1800 rpm does not mean that there is no problem driving at low RPM -- the alarm will not go off there at any pressure. I had my sensor unhooked for a day, while I had an oil pressure gauge installed temporarily, so that I could watch the pressure as I drove. Every time I revved above ~2000 rpm, the STOP light and beeper would come on while I had the sensor disconnected.

    It takes several minutes after the water temperature is up to 190F/88C for the oil to get hot.

    If you drive it you will ruin your engine. There isn't enough oil going through the engine to lubricate it. You need to get it fixed and DO NOT drive it. You could very easily cause 4-5 thousand dollars worth of damage and then you would have wished for a $1400 bill. I would suggest you get them to replace the turbo oil lines and do the professional engine flush if it were my new car. This is a serious problem and seeing how you got it from a used car dealer I would bet this has happened before. The engine is probably full of sludge.

    I already thought about that. And i changed the oil pressure sensor because they told me that it didnt work, after it was changed that light dissapeared for around 4-5 days.

    So the coverage is different from the USA. Here, I believe all you have to do is maintain it properly, and keep your receipts since purchase (from wherever).

    Safe to drive? I wouldn't. Last (and only) time this happened to me, I was in a Jetta in the middle of the night. Fortunately, I had a mechanical oil pressure gauge; I could diddle the RPM to keep the pressure up. I nursed it to the dealer, left it and walked home.

    If you do not correct this problem it will continue to get worse.

    46000 miles ago my 1.8 had the same problem as yours. A can of 5 minute engine flush followed immediately by frequent oil and filter changes (0 mile, 200 mi, 500 mi, 1000 mile) seems to have resolved the problem. Removing the oil pan for cleaning and replacing the oil pump intake is another choice, safer too. Low cost parts but labor expensive.

    Don't drive the car when the warning light is on, sludge has covered the intake screen aand oil pressure is critically low. With the light off there should be suffieicent oil pressure to keep all the moving parts lubricated.

    While you are in there anyway, you might consider changing the oil pump. $139.85 on-line from 1stvwparts.com, or pay the local price if you don't want to wait. I think that includes the oil pickup tube.

    Hmm..... do u think i really need it? because the guy from dealership gave me 3 page of parts, but he circuled only 4-5, because he that those are i basically need and the rest - not really.... and he didnt say a thing about my oil pump.

    so you have changed those parts, then flushed the engine and the problem was gone right? if it is not a secret - how much did you pay in total? And do i get some kind of warranty on those parts?

    thanks a lot

    Yes get a new oil pump and pick up tube, get the engine flush, and I would replace the oil lines to the turbo as well. VW has a professional flush machine (some shops may have them as well). If there is ONE thing you do replace the oil pump as its the little screen in the pick up tube that is clogged. It may get clogged again soon if you don't do the flush.
