Audi A4 2.0T 25,000 Mile Update

Jiffy Lube and other oil change vendors recommend changing your oil every 3,000 miles. My dad (who worked for Getty Oil & Texaco) always told me that anything less 5,000 miles was unnecessary. Audi recommends this service only every 10,000 miles or after a first service at 5,000 miles. Which brings me to the topic of this post, the 25,000 mile update on my Audi A4 2.0T.

On Monday, I dropped off my car at Rusnak Audi in Thousand Oaks for the service that was due. I make sure to mention that I do have a “chip” or ECU upgrade on my Audi A4 just in case the notice anything abnormal. It helps that Rusnak and Neuspeed have an excellent working relationship. My service advisor mentions that there is a ECU upgrade from Audi, so I may need to have the software re-installed at Neuspeed (no charge) if it happens to wipe it out. The only other major item done at 25,000 is replacing the brake fluid.

A few hours later, I get a call that my car was ready and by the way we had to replace a valve, under warranty. Immediately I was concerned – just a couple of months ago (link here) my turbo bypass valve had to be replaced, which I possibly attributed to the additional boost coming from the ECU upgrade.

Fortunately, the valve issue was quite different – something that my service advisor mentioned was more common on these A4 2.0T’s. Basically, the crankcase breather valve had to be replaced along with the associated gasket – as a whistling noise was detected from the engine during the test drive. Here is the text from the service receipt:

“Whistle type noise coming from engine. Crankcase breather valve sticking. Causing excessive crankcase vacuum and oil leaking from filler cap. Perform GFF. Replace crankcase breather valve.”

When I read this, I realized that when I had the previous problem, I noticed some oil on the top of the engine. So, most likely this was an issue when my turbo bypass valve went causing the check engine light to come on. So it is possible, that this has been an issue for the last 5,000 miles or so.

Let’s just say at this point that I am glad this car is a lease car. And, if I end with a 2009 A4 or S4 model when this lease is up – no question I will get the extended warranty should I decide to purchase it.

Would I have had the problems without the chip? I am not sure, but it seems like the crankcase breather valve is more common than it should be according to Audi.

On all other fronts the car is dong very well. The most exciting part is that I still have over 30% left on the tires. Which, according to Brian – he’s surprised that with the way I drive I did not burn through these higher performance tires in 20,000 miles. It looks like I can make it to the end of the lease without needing to replace them. Exciting!

While I was not able to capture the details about the version upgrade for my engine management system on the A4, I can tell that it did not wipe out the Neuspeed ECU programming. The same power is still there in addition to whatever else Audi decided to add in. I may give Neuspeed a call to see if they want to flash it again – just in case parts of the program need to be adjusted. completely remove the ECU (chipped) programming from my Audi A4. I do need to call Neuspeed and get the programming updated.

But other than the 2nd valve problem in 10,000 miles – the Audi A4 2.0T still looks and runs great. That should not be news, that is what you expect from it just 25,000 miles into the car’s life.

For what it's worth, I have an '06 A4 2.0T Q and had the same problem with the PCV valve at 16,500 miles and mine is not chipped.

Good to know, thanks for the comment. Makes me feel much better about the issue. :-)

We have an 07 A4 Avant without a chip and also had this problem. All the oil had come out of the filler cap and was all over the engine. The dealer replaced the valves and cleaned it up and so far we have not had any more issues.
