Sunrise v. W. Had my 2009 Jetta tdi in their shop yesterday, and after diagnostics informed me that I needed both cooling fans, and the intake manifold replaced. I have geico mechanical break down insurance. The adjuster only approved the replacement of the cooling fans. On the way home my check engine light came on, I heard a pop sound from the engine, and lost all of the cars power. This loss of power happened while traveling in traffic at about 30 mph. I believe the intake manifold failed, and caused the loss of engine power. The car was then towed back to sunrise v. W.
I bought my brand new 2009 Jetta tdi on 5/28/2009 and 2 days later after I had only driven the car for 200 miles, the air conditioning stopped working when the car was sitting still. I opened the hood after I got to my destination to realize that the cooling fans were not working at all. They would not even come on to cool the engine. This occurred on a Saturday, and the vw dealer where I bought it was closing in an hour. Their master tech agreed to stay until I got there and he ran some tests on it, and told me he simulated a severe engine overheat and the fans still did not come on. He said the car could not be driven and it would have to stay at the dealer. He said the fan relay was faulty and would have to be replaced. Then Monday morning the service manager whom did not believe the master tech decided to drive my car with a non-functioning cooling system to see if he could replicate the problem. He called me to discuss the fact that the air conditioning worked while he was driving to which I said it will when you drive it, however, it does not work when your come to a stop because the fans do not turn on. He finally decided after a day of wasted tests to order the part. I finally got my car back today after they had it for 5 days of the first week I owned it. I am so glad I purchased the 100,000 mile warranty, because that sort of problem after 2 days of ownership does not say much for vw. Everything was covered under warranty, but I was still without my car for just shy of a week. Diagnosed part= cooling fan module failure.
