car was in the dealers today ( see date ) for a basic interim service.
Whilst there I was advised of an issue with my "Inlet manifold actuator".......stuck / not working or similar and needs replacing.
I'll get round to doing some more intensive research, but in the meantime can anyone offer any help on this?
What is it exactly and where is it fitted on the engine ( Inlet manifold obviously ) before anyone pipes up....lol
Any pics of it? And location?
Prices expect to pay? Audi are around £15 but the labour to fit will make it around £280 all in
I'll probably go with Aud to be fair, but still like to do my research for future reference.
Thanks to anyone with any assistance on this

Ok, so had the car back in at Audi today as this juddering / violent shaking at certain times is concerning.
I've also thought I noticed an increase in fuel consumption too, enough to make sure I get to the root of the cause. Just as an add on I feel sure that the car is under powered from where it would be normally, just a little but definitely there......
Audi tech came for a road test today after I had explained the issuesm then the car was put onto diagnostics and the Intake manifoldactuator again came back as faulty and needing replacing. As already discussed the part itself is around £12 but fitting requires the removal ofthe EGR valve and then the intake manifold, so around 1.2 - 2 hours is allocated and hence a price of £266
I've just decided to bite the bullet and get this done ASAP, and the car's booked in for next Friday morning.........It's a lot of money for what it is, especially at this time, but if it resolves the issue I'll be happy enough.
Of course I'll report back when its done.

I feel I've noted a significant increase in fuel consumption from where I would normally be.
I refuelled today with DIS showing 35 miles till empty and spent £91.00 filling with 61.95 litres of Shell VPower diesel with miles travelled of 469.6
As stated the car is always serviced regularly, has had sometimes 2 oil changes per year, new air filter, new fuel filter in July, was Terracleaned as well as cleaning my EGR valve too.
After all that the mpg was good for sometime, yet recently has begun to drop IMO.
I have also had issues with the car getting to temp I believe so have had my thermostat changed a few weeks ago.
The only thing outstanding is this Inlet Manifold Actuator which will be replaced on Friday at which point I'll monitor it again. Depending on the results I guess I'll be looking at the MAF / MAP sensor ( need to check ) and go from there.
As stated I'm hopeful that the IMA wil resolve my issue.....If not I guess the MAF will be next.
Any helpful comments / suggestions are welcome as always
