2001 golf gt tdi diesel. Traction light comes on now and again by itself other times it's fine.
Also same car has power problem. Runs fine then sometimes i have no turbo power at all. I switch off then re start & seems to be fine until it does it again. No eml lights on. VW specialist code read it & says its a alternator problem also high lighting voltage regulator ??? Already cleaned egr valve. Many Thanks for any help

Hi, The EGR valve itself is on a set of flexible pipework - usually stainless steel - which runs between the inlet manifold and the exhaust manifold. The EGR actuator valve is pneumatically / vacuum operated by a solenoid valve, controlled by the ECU ( aka the brane). It's not usual for the EGR valve itself to fail, more likely the solenoid valve or its electrical connector getting dirty. If you google for VAG TDI N75 valve you should get all the info you could possibly ever need :-)
Hope this helps, D.

It's probably the turbo you're hearing. They spin very fast and make a noise like that. Ever hear an 18-wheeler go by you and accelerate and they make that high-pitched whistle? That's the turbo spooling up. Now, if it sounds like a dentist's drill, that's usually a sign that the turbo is failing, but I'd bet that since your car is under four years old, as long as you've kept up on the maintenance, it's the normal turbo spool.

Hey spend the extra cash and go direct to VW web site, most manufactures offer online manuals for a small fee. well worth it, especially on newer timing belts. its not your old 85 toyota. good luck

check the turbo hoses, they are renound for dry cracking, very hard to see at first glance
