I was driving to work, which includes crossing a toll bridge daily. I was on the bridge, which is only a 2 lane bridge, when all of a sudden my diesel engine failure light began to flash. I lost acceleration and was able to pull off to the shoulder safely and turn off the car. I sat there for a few minutes contemplating if I should call aaa to get a tow to the dealer. Seeing as I was only about 5 miles from the vw dealer, I decided to see if my car will make it there. It started back up no problem and I was able to accelerate back into traffic and make it to the dealer with no further issues. I explained the problem to the service rep. And they checked in my car and I waited for them to call me with the issue. Later in the day, I received the call from the service rep. , and he informed me that the high pressure fuel pump failed, and they will have to rebuild the fuel system, as there were metal particles found in the gas and gas lines. He said this sometimes happens when a customer may use biodiesel fuel or a lower grade of diesel. He also said that they would have to send the gas samples off to vw lab to review in order for the repairs to be approved since I have the extended warranty. I am shocked that this occured, seeing as my car is only 4 years old and less than 50k miles on it. Thankfully, there was not an accident and no one was hurt.
I was on my way home after work approximately 6-7 pm doing 45 mph. I looked down to my instrument cluster to check my speed to make sure I wasn't speeding. Then I saw the glow plug light blinking multiple times then about less than 5-10 seconds later my engine cut out. I cost off into a harper college parking lot came to a stop. I tried to start the car 2-3 times, each time the engine was crackin over but wouldn't start it up. I called the tow truck company and had the vehicle towed to vw dealer in schaumburg, IL ( fox valley vw) dealer said the high pressure fuel pump failed. Vwoa cover this under power train warranty 5/60k warranty. The dealer replace hpfp,lift pump, pump in gas tank,fuel lines to engine,coils etc. . . Repairs came to roughly $5300. 00. Vwoa only give 12/12k miles warranty on the hpfp. This is a known problem on some vw with cjaa 2. 0l turbo diesel engines and vwoa has not found the defect in the hpfp. Vwoa should extend the hpfp to 100k miles due to deft in the hpfp since they haven't found the problem and corrected it.
The fuel pump in my car's 2. 0 tdi diesel engine broke.
