Yes, that seems right, the EGR valve should be black and dry and if clean, then coolant is leaking and steam cleaing the valve. I assume that you also have white smoke from the exhaust and missing coolant from te radiator.
What is "engine lift?"
I will look out the instructions this evening and post some more information. PM me your email address.
I recently bought a new Q5 3.0ltr and my company has kept my old one as a pool car. The EGR warning light came on a few weeks ago but didn't effect the running at all. The quote from Audi was £1350.00 to replace and just had it done by an independent garage for £313.50 including VAT and all labour. The part was £163.50 and labour 5 hours at £30. Light is now off and car as good as new with 113000 miles and still running sweetly.
Swirl flaps are located in the inlet manifold and looks easy to replace. Not really part of the EGR.
The air induced via the front end flows along a plastic air line to the
throttle valve. After leaving the throttle valve, the recirculated
exhaust gas is admitted to the intake line in a flow-optimised
fashion via a thermally decoupled sheet-metal intake made of
The geometric design of the exhaust gas intake helps to avoid
build-up on the inner wall of the plastic tube at all operating
points while ensuring a good degree of mixing.
Throttle valve control unit
Twin-fl ow intake manifold
Central swirl flap
In the new TDI engine swirl is controlled by a single swirl flap, as
compared to the six swirl fl aps used previously in the (first generation)
3.0l V6 TDI engine. After the central swirl flap, the intake
manifold has a twin-flow configuration up to both cylinder banks.
The upper half channels air into the swirl ports and the lower half
into the charging ports.
For this purpose, plastic intake manifold comprises three frictionwelded
shells. The intake manifold geometry was enhanced over
the course of several calculation loops with respect to pressure loss
and uniform distribution of the air fl ows to the individual cylinders.
If you PM me you email address and I can send pictures.
Thanks - that sounds like good news then - it sounds like a problem on the old car. A case of too much googling by me! Audi did not suggest replacing the swirl flap links etc - so I shall just let then get on with replacing the erg cooler - Im guessing the only difference I will notice is the lack of orange glow from the dashboard as otherwise the car ran perfectly. Thanks Mark
Just had a look at my A7 3.0tdi and can see that in rider to remove the egr valve, you have to remove the inlet manifold and hence the swirl flaps. The swirl flap looks like its electrically controlled and not a cheap item. In any event it is easy to replace at ant time whereas the egr valve is a bit more involved.
Five stars for Liverpool Audi. Please pass our appreciation of their excellent service. I would however like you to answer the following questions in order to understand whether this is normal practice or did they do something special for you. Did you buy the car from them? Did you buy it new? How many cars have you bought from them? Did they service your car from when you bought it? Is there anything in your relationship with them that encouraged such a service? I feel that these are important answers we would like to know in order to understand what drives good service. Thanks
Lol, It's just good service. I have no special connection with Liverpool Audi. I have had my cars serviced by them for the last 5+ years. I have not bought one from them yet, but that may change next time round. I am the second owner of the q5, having bought it with 73k miles on it.
I do always make sure I say please and thank you though!
