Update! Went to my local Audi specialist. He told me there is no way you can get around 26mpg driving town/stop start in a 3.2!?! He wouldn't even entertain the conversation. He has however agreed that 19mpg is a little low......he thinks it should be around 21-22 for my driving style. Goki and whodafunk - you must just have two diamond 3.2s of the production run......no two cars are the same I guess. Booked in for a software check and connection to ODIS to see if my car can take the software update I referenced in my original post. He is also going to do a general investigation into mpg, checking all sensors and exhaust etc to see if there are any issues. Thanks for all your help and advice so far on this...I really appreciate it.
