Hi, I'm up on the Sunshine Coast, Qld. I have a 2008 C5 2.2L HDi Twin Turbo sedan, VIN VF7RC4HSJ76838887. Economy has suffered over this last year dropping from about 7.3L/100k to 9L/100k (around town) and similar reduction on Highway cycle economy. It is also running a bit rough on idle. So I am looking for a good man who realy knows his stuff when it comes to servicing this diesel engine. Can anyone give me a good contact for me to follow up, preferably local but if I have to go down to Brisbane (150k), so be it. Thanks.
