Volkswagen Passat Engine Issues



  • I just had my driver side cat replaced on my 2001.5 GLX, and when I got the car back there was no heat. Is this a coincidence or could they have bumped something? Before I spend thousands replacing heater cores and water pumps I want to know if there is a logical first step.

  • Thrown a code on cylinders 2 and 3, purchased 2 new coils and put them on 2 and 3 and also put in 4 new spark plugs. It continues to run like crap..
  • I am a third owner of a 2000 VW Passat and ever since I have owned the car, i have had nothing but issues. I recently (2 months ago) have replaced the Turbo in the car (1.8) ~$2000.00 later, my new and honest mechanic, who openly told me, get rid of the car, because its only going to give you more trouble. What I dont understand is VWOA is responsible for these issues, and they should take full responsiblity that they made a hunk of junk. The guy who sold it to me totally stuck it to me, he new i was desparate for a car, and not knowing because im a broad he took total advantage of the situation ~ To all the people who are even looking at the VW Passat turbo especially, dont buy it, you will be in for a costly ride. My car also does something funky in the morning ~ if the temperture is above 35 degrees, when starting it starts doing what i call the engine dance, the check engine light blinks and then after for about 2 minutes, it stops blinking and the engine stops making noises like its going to blow up. If the tempature is below 35 degrees, it doesnt do it at all, just the stupid "Emissions workshop" light goes on after i take off ~ anyone ever heard of this? What a PIECE OF CRAP, VW of America, go back to Germany, I hate you! Oh, and a FYI: I am the victim of the oil sludge issues that are happening with these cars, my mechanic cleaned out my car for hours ~ If you live in RI and you need a excellent mechanic, A & W Tire in Smithfield, John the owner is a GREAT GUY and very very honest!:mad: :lemon:

    I'm afraid that I need to rain on your parade a little. The VW (and Audi) turbocharged engines are no more or less reliable than any other turbocharged engine, ASSUMING that they are properly maintained. Said another way, you cannot simply dump in any old dime store brand of oil like you would for a 1975 Chevy and expect it to continue to run.

    If you read through the posts regarding the care and feeding of VW turbocharged engine (on this and other sites), you'll notice that a high quality fully synthetic oil is REQUIRED, and if you don't, sludged engine and coked up turbocharger bearings will be the guaranteed result. In your case, blaming VW for the failure of the first two owners to properly maintain your car is a tad disingenuous don't you think?

    Im not going to disagree with you there, the previous two owners obviously didnt take care of the car. However, you simply cannot deny that there has been issues with the 2000-2003 Passats on the turbo issues and the sludge problems. I knew a person that bought the car brand new, that experienced sludge issues. the only thing I need to do is try to get an oil change every 1500.00 miles to make sure the suldge doesnt build up again. Yes I do blame Volkswagon of America for not looking into these issues, even the NSTA (hope i got that right) has statisics on these cars that they (VW) made poorly. Google VW passat, you find more problems than praises... :lemon:
  • shiposhipo Posts: 9,152
    Sorry, I still disagree. For the 2000-2003 1.8T engines, once VW identified the need for synthetic oil, they published the 502.00 oil specification and announced that the oil requirements for the older cars were retroactively changed to require oil that met the new spec. In addition, they extended the warranty of the older engines so that if you could prove that you'd maintained your car to the requirements in effect at the time, they'd buy you a new engine if yours failed.

    The problem here is that many service centers, dealership based, chain (Jiffy Lube et al.) and independent shops chose to ignore the new directives and continued to use whatever oil was on hand. The obvious result was a bunch of 1.8Ts that were sludged to the gills. Once again, not VWs fault, they took action when they recognized a problem and then had to deal with the fall-out of folks not heeding the new standards.

    FWIW, I've owned a couple of turbocharged engines myself, and after hearing the horror stories of oil belching turbocharger bearings, I always used synthetic oil in my engines. Not surprisingly (to me anyway), both of my cars made it past 100,000 miles with zero hint of any issue with the turbo. Back in the late 1990s when the 1.8T made its debut, I told everybody I knew who had one to make sure to use synthetic oil. Those who did never had a sludge or turbo problem. Those that didn't... Well, you can guess the rest.

    Don't believe me? Ask around here; there are a number of folks who post from time-to-time who have your same engine in their VWs and Audis. They'll tell you that the 1.8T is a very good, very strong engine that will easily last the life of the car, IF properly maintained (i.e. VW 502.00 or 503.01 spec oil and no oil change intervals of more than 5,000 miles).

    Best Regards,
  • yes i was just wondering if a vr6 motor from a 93 passat would fit in a 94 passat? I believe they have the same engine but was just wanting to make sure.
  • shiposhipo Posts: 9,152
    I'm 99% positive that the 1993 mill will fit in a 1994 Passat. You could call your local bone yard and ask them to check their interchange guide.

    Good luck and keep us posted. ;-)

    Best Regards,
  • Nice response, shipo - couldn't have said it better myself..:)

    Being a current owner of two 1.8Ts (2003 Wolfsburg Jetta @ 107,000 miles and 2003 Passat GLS 1.8T @76,000 miles), I definitely concur... These engines will last a long time with proper maintenance...

    Welcome to the era of personal responsibility (or lack thereof) - buy things on emotion without doing the proper research or homework (especially on a big-ticket item like an automobile), don't take care of said item properly, then find someone to blame (sue) when something goes wrong - the Great American Pasttime (nowadays) :(
  • I own 99 VW Passat GLS, everytime I gas up the car does not start I have to pump the gas pedal a few times, then it eventually gets going again. I recently change the fuel thinking that was the problem, well it was not. Anyone have the same problem?

    Sorry to hear of your troubles with your Passat. Too bad you hadn't found this website before you made the purchase. I guess now you know why the guy sold the car. Being desperate is the worst condition to be in when car-shopping.

    Personally, I would never buy a used turbocharged vehicle, period. Too many issues can come to haunt without full knowledge of the previous care and feeding of the engine.

    Oh, and Shipo, the 2003 manual (see below) doesn't specifically say you need to use synthetic, but if you read between the lines and the specs they want, you'll realize it soon enough. When I bought my car, the recommended 5w-40 was only available in a synthetic formulation, to my knowledge. The manual, IMHO, could have been clearer.


    Here is a link to Motul's outline of what the VW specs really mean:
    Motul VW Spec Sheet.
  • shiposhipo Posts: 9,152
    Interesting page. Thanks!

    One thing I find interesting is that your manual doesn't seem to allow for 502.00 oil. That seems to be contrary to what the bulletins that VW and Audi have published over the last couple of years have indicated. Hmmm. That said, I wouldn't use anything less than a 503.01 anyway so it won't be an issue for me if I end up with an A3 2.0T (I drove two yesterday and geez, what a fun car).

    Regarding the Motul link, that was pretty informative too. That said, I'm stunned to see that they're recommending an OCI of 18,600 miles when using a 503.01 oil. I'm thinking that only a fool would go more than the recommended OCI on these cars regardless of whether you're running Motul, Mobil 1, German Castrol, or any other approved oil. :confuse:

    503.01spec was really difficult to find in '02 when I bought the car. I received the addendum to my manual from VW that in fact lists 502.00 oil as the recommended spec. I'll post that when I have a couple of minutes.
  • shiposhipo Posts: 9,152
    I got my first BMW in 1999 and that car needs oil that meets BMWs LL-01 oil spec, a specification that generally runs hand in hand with VWs 503.01. Back in 2000 when I did my first oil change on that car I had to buy Mobil 1 0W-40 from a Porsche dealer down in Dallas vial mail-order. By 2002 I was able to occasionally find 0W-40 at my local Autozone, and once the started occasionally stocking it, they were more than happy to order me those 6-quart mini-cases and even sell them to me at a slight discount if I bought four or more cases at a time. That was when I started using 0W-40 in all three of our cars (even though two of them call for 5W-30). ;)

    Owner's Manual update for use of 502.00 Spec Oil (sent to me by VWoA for my 2003 1.8T model):



    And here is the Time/Mileage Chart from my manual (basically 5,000 miles or 12 months unless driven under severe conditions):

  • shiposhipo Posts: 9,152
    Color me shocked. :confuse:

    So, let me get this straight, the owners manual that came with your 2003 Passat specifically recommends 503.01 oil for your gasser Passat. Sometime after purchase, VW then sends you a suppliment that calls for 502.00 oil. Hmmm, odd.

    BTW, thanks for the pages. ;)

    "Yes" to all of your points. 'Course, I'm using 503.01 M1 now, though.
  • Hey folks,

    I just read in another forum that there could be a potential issue with the V6 engines on the newer B6 Passats.

    Has anyone here ever experienced an Oil Pump Bolt failure in their V6 Passats?

  • I bought 08 Passat 2.0L 4cyl Turbo 6A. The country of origin of engine is Hungary and transmission is from Japan. I wonder if all Passat engines are from Hungary. Is there a concern that the quality of the engine may be inferior than if it's made in Germany?
  • From my experience with cars in general (and VW is no exception) reliability is always a factor of Design, Part Quality and Build Quality.

    The older Jettas had a ton of issues in the US, but hardly any in Europe. The design is the same, but the parts and final assemblies were different - with obviously different results.

    The VW Bugs are so badly designed (electrical), even the Puebla plant couldn't possible make it any more unreliable like they did with the older Jettas.

    I don't know about the quality of the Hungrarians, but from personal experience, the Mexican and Brazillian plants don't know the meaning of the word "Quality." The only VW cars I will ever buy have to have the major components from Germany or Japan - because VW has poor quality controls on their outsourcing / off-shoring operations.

    That said, this is the Passat, and VW will be shooting themselves in the foot if they allowed an inferior built engine into their flagship product.
  • I searched a little bit and found it has been a few years that VW use engine made in Hungary on a few VW lines. other owners may confirm this.

    Question is why VW move the most important part out of Germany? Are they completely satisfied with the quality of the engine made in other country? Are they regarded as identical? I guess the quality was acceptible by them. I red on this forum that some kind of ring went off the engine and the mechanic said they have seen a lot of this problem.
  • altair4altair4 Posts: 1,469
    Question is why VW move the most important part out of Germany?

    The answer, as it almost always is, is money. The pay rate in Hungary is considerably lower than in der Homeland.
  • That's a safe bet only if the quality remain the same. If the engine became mediocre that car line will go downhill. Even they can maintain the same quality it still cast doubt in many consumers. That's a strategic move for them. Maybe they believe they will never catch up or beat BMW or Mercedes so they try to compete in the family cars like Accord and Camry.
  • altair4altair4 Posts: 1,469
    All I can tell you is that the Audi engine plant at Gyor has been in service since the early 1990's. They built the 1.8T's there, too, used by Audi, VW, Seat, and Skoda. They make 12 cylinder engines there, too, not just the 4 bangers.

    I wouldn't sweat it. Now, the electronics, OTOH....

    Motto : "Timing is everything"

    I scheduled "Engine Coolant Temperature Sensor" replacement with independent mechanic on Monday and this Saturday I got a letter from VWoA that beforementioned sensor is now covered by extended warranty (10 years or 100K miles).

    I think it is 6th service/recall with this car.

    In my car the temperature gauge is capable of dancing from normal to 0 and sometimes back. Warm/hot air comes out but gauge shows 0.

    Apparently it can cause even more problems, the biggest one probably is that some states fail emission test because the "Check Engine Light" (MIL[Malfuction Indcator Light] in VW speak) is lit.



    PS I will cancel my visit on Monday to have it done for "free" at dealer.

    All VW & Audi engines are made in Hungary. I was in Wolfsburg (VW World Headquarters) and Ingolstadt (Audi's World Headquaters) and both companies confirmed all engines are made in Hungary.
  • VW have better update those CAR stickers then - since they point the v6 engines to be from Germany.

    ... unless Germany "annexed" Hungary... :)

    Wrong. Only the Volkswagen R32 qualifies itself as a full German-made Volkswagen with engine and transmission Made in Germany. The 2008 R32 is predicted to be the last full German-made Volkswagen vehicle ever made.

    I had a diagnostic done to my 02 Passat and said It had a misfire on coil #1. So I put a new one on. The problem wasn't solved. Then I also changed the valve ( or whatever that part is called ) that goes beside the coil and the problem sill wasn't solved . I'm a girl. Help me. What could It be?

    I have two 1.8Ts (Passat and Jetta). I have a rule of thumb. If one coil goes out, replace the entire set (around $35 for each coil x 4 coils) - because chances are more than one coil has failed.

    Let's put it this way - spark plugs aren't changed one at a time - they're usually changed as an entire set. The same logic should be applied to the coils.
