Audi Repair: 2002 Audi A4 3.0l quattro DTC 17550, vacuum leaks, position sensors

Question
Hey hows it going? having some problems over here getting a VAG code of 17550 will not go away. So far I have replaced my MAF and Accelerator position sensors and code just keeps coming back was wondering what the next step is to resolving this issue. bad Throttle Body? or Bad ECU? tired of spending money on repairs that don't fix the problem. thanks in advance

Answer
You need to check the wiring to the MAF, also check very carefully for vacuum leaks, on the connecting hoses near the MAF especially.  Usually this is a split hose, or a bad MAF.  You've already replaced the MAF so check for the cheaper, but perhaps trickier problems.  Keep your old MAF as a spare...  Let me know what you find,  Jan
