Thanks for the tips.....I get fuel from morrisons or asda mainly,no longer near a shell station.
Ill get it scanned again as my vagcom is out of date I believe
Thats your problem then, did you not see that programme on Petrol, Morrisons came out worst off ALL the petrol stations in the UK.
They buy a basically watered down version for much cheaper. Switch to Shell or main petrol station for a week and you will be blown away with the difference. Shell is like 4p more a litre , so like £2-£5 depending on how much you put in, but will return Soooo many more miles.
Let us know after a week
