2007 Audi A4 Quattro ProblemsCheck Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump
2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.
2007 Audi A4 Quattro QuestionsThe wipers start and stop at random and the hazard lights won't turn off. (1 answer)
We have tried to replace the comfort module but it did not help. When I put the wiper fuse in they start and won't stop.
It would lose power only now and then and specially I when I step a bit more on the gas. And the engine light comes on and flashes for 4-5 times and goes away. What does this mean and am I able to fix it myself?
I have checked for leak and there seems to be no leak.. Now it's showing that the car needs to be serviced . Do you think anything is wrong with the gauge?
