I have an Audi 1.8T 2004 4 dr. Quattro. 96K. Just did long dfrive from Denver to Phoenix, now I hear a constant clicking moise coming from the mid point of the car. It is there whenever the engine is running (idle or ingear going). Nothing is loose under the under carriage. My ideas so far:
1. fuel pump
2. oil pump
oil pressure and all gauges read nml no warning lights, still runs and temp is in nml position. Any thoughts? and if so how much for parts or to have local garage replace it?
