Hi,

I agree with you AUDI seem to know nothing about this problem! NOT!!!

After reading the forums I'm going to replace the EGR Valve & see if this sorts the problem out Audi Part Number 1H0906627. You can get this from Euro Parts for approx £59 + Vat it is £20 cheaper than Audi Dealership. I think they call it a Pressure Convertor! I think Audi will only wake up to the situation & put their hands up when somebody has an accident or worse!!!!!

Try cleaning the hot side of the turbo first!! I did and it's so much better

your right and even then most of the cars with problem are 3 years old and more like mine so thay prob wont take anything to do with it! we are changing the accelerator pedal today! coz its fly by wire (if i have that right!) theres a box on the side of the pedal that has a chip board in it (I opened it this morning) so i'll let you know how we get on with thiat.

before the audi i only ever had vauxhalls! (in the good days) one of the used to not idle properly and would shudder on the off take and stall but once your re-started it, it corrected its self and i was told it was the EGR valve! i replaced the air flow meter and the idle control valve and the thing ran like a dream, but different car so not sure if it would be the same .

Hi,

I know it's been a longtime but thought I would let people know what sorted my A4 out!

I have a friend who works for the AA - He cleaned all the pipes to the turbo -cleaned out the EGR Valve & cleaned the actuator!

Hey presto it's working !!!

If I took it to Audi they would have charged me the earth but I hope this helps other users because it is a common fault but Audi will go through the motions of diagnostic.... blah blah... just to incur more cost to the customer!
