OK, now I am irked at my dealership. I had the 20K service done, and the fuel filter replaced. After getting the car back, I noticed a hesitation or stuttering when first starting the car. After waiting a week and a half for it to clear up, I took it back to the dealer, thinking the problem was the air bubbles I could see in the diesel fuel line. The bubble is bigger if the car sits longer.
Initially the dealership manager seemed to agree this was a problem, but now claims that "every car on the lot" has air bubbles in the fuel line. I'm no mechanic, I don't know...
So, is a 1/2 to 3/4 inch air bubble in the fuel line normal after a TDI (2003 Golf) sits in the parking lot for 10 to 12 hours on a cool day?
My theory is that there is a slight air leak somewhere around the fuel filter, causing the power loss and thence the air bubble. I never noticed air bubbles in the fuel line before, but I rarely look under the hood so that may not mean much.
Car is at the dealership today being looked at.
