Thank you all for your kind thoughts. Gareth when I say I made a fuss what I did was to firmly state when offered that I had heard many reports of affected performance and mpg from this software tweet and given the option I would prefer not to have it. I was concerned that the car would be plugged into a central server at some point during the service and this adjustment would be made inadvertently. I asked the service manager to acknowledge my request in writing which he was most willing to do. So not really a fuss. My main concern is that there appears to been a general fault with my era of A7 and who knows other vehicles fitted with the same motor. Here is an extract from a mail to me from their my Huddersfield service consultant. “Following on from the conversation with Audi UK, as I mentioned to you on Tuesday as a centre we have experienced similar noises on the A7 3 Litre's previously. Along with this a modified Camshaft has in fact been released from Audi as oppose to the original camshaft fitted within the vehicle from factory & we have confirmed similar faults with our technical team in Milton Keynes.
Here is a link to another forum on this site “
This clearly indicates an serious wide spread problem which A Mr Nasar, end of the line at Audi UK, explicitly denies exists. At this point a have to say that I think Audi Huddersfield have been excellent and given me as much support as they can Audi UK however seem to be in denial. I wonder why. Comments Please
