I've been having issues with my 03 tdi. I took my turbo apart to clean it and I tried spinning the turbo blades on the exhaust side and they would only spin about a half turn before it stopped. Should a turbo in good condition spin more freely? Also are aftermarket MAFs any good? thankyou

By aftermarket MAF do you mean Bosch? Bosch makes the MAF sensors. It's hard to say how hard you spun it and how it was sitting but that sounds about normal. It should rotate without resistance and without grinding.

What about the aftermarket MAFs on ebay for $50-75? And I bought a brand new Bosch MAF because my old one wouldn't go above 550 and the brand new one had the same read out and I was wandering if you ever heard of a car destroying MAFs or if it was perhaps a defective MAF.
