Volkswagen Passat Engine Issues

    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 ~

    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:

    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.

    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):

    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.

    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.

    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.
