Re: Car won't accelerate
That sounds like your car is stuck in first gear. its not a good idea to keep the engine rpm's up that high as it will cause damage to the engine. check the transmission fluid level in accordance to the owners manual, if the fluid level is ok and the fluid isn't burnt, it may be a control module, sensor, or solenoid malfunction that's causing the car not to shift. if the fluid is burnt or smells really bad that would be a sign of transmission slippage. in which case it would best to have it looked at by a dealer or reputable shop. hope this helps.

sounds like an exhaust restriction or a transmission problem causing your problem. check trans fluid level and condition. you can have a test done for the exhaust restriction by doing an exhaust backpressure test at idle and at 2,000 rpms. if this is good then have the transmission checked for a problem.
I don't know what whosing sounds like, but I have a high pitched whirring noise coming from my somewhere in the engine bay, my noise starts when the car starts and continues while driving, goes away at around 60 mph but will come back when I accelerate or decelerate, I have a friend that is a master tech at volkswagen, he suspects the alternator is making the noise, this is my first TDI, I bought it with 150k on it, I don't have any experience with TDI's, but am a Service Advisor, and it has been my general experience that all volkswagens are posessed! :) Always having some sort of electrical issue, Not sure if that will help.... Good Luck!
The whine sounds like the power steering or the alternator, as far as the idle issue goes try this clean the intake throttle body and idle speed control valve with carb spray, disconnect battery for 5 min. then reconnect and drive a few miles to reset idle strategy. The car will try to die when you spray the intake, hold the idle up to prevent that, use at least 1/2 the can of carb spray.
