Throttle Body problems

[Audiohitch]

Hi, been a while that I've been on here.
Heres the problem;
I have 2009 Audi a4 2.0 tdi 143, the drive of the car is fantastic but I do have a couple of problems, the glow plug light flickers infrequent and the engine management light is on, I've borrowed a basic fault code reader which read p2102 & p2103, I understand this to be some sort of manifold flap??
This has been cleaned out, however oil was found in the electrical connector.
could this be the main source of the problem. A oil leak going through the throttle body into the electrical connection. theres no sign of oil anywhere else or on the outside of the connection or engine.

Probably the inlet manifold flap motor (aka anti shudder valve). Does the car shudder a but when you turn off the engine?
Has been common in VW diesels for ages, oil gets into the plug, the internal cogs shear off and so on.

If that has failed, eurocarparts sell the OEM part cheaper than a dealer.

Just replaced mine, same symptoms. Got it from http://www.darksidedevelopments.co....cr-anti-shudder-valve-asv-03l-128-063-af.html Fitted and cleaned up the EGR too. Runs like new again. No errors and no Shudder on switch off.
