My sisters a3 is running a little rough when stationary feels like its hunting then on occasion struggles to start i think its a fuelling problem any ideas?

and the engine is?

Sorry 1.9 tdi thinks its 110 bhp or something slower than my gtd 170

105bhp, when was the fuel filter last changed? If she is using supermarket fuel try changing to branded fuel for a couple of tanks.

 

[Matt_j1987]

I changed it about 3 months ago and was changed before that on the annual service she uses supermarket when she has to but mainly branded fuel as she was told about the crap additives in supermarket fuel, i run on supermarket never had an issue runs better and get more to the gallon then on shell/BP i'm not made of money

Lol that made me laugh. U have a GTD but aren't made of money?

Get it off that rubbish and put some decent fuel in. Chuck some forte in and take it for an Italian tune up

Love it when people say they can't afford decent fuel, for the sake of like £5 more a tank I hardly think it'll hurt the wallet too much!

I'd like to stay on topic but the fuel costs more and does less to the gallon so's costing me twice
