Hi one and all. Purchased A5 40 tdi just over 12 mts ago and been pleased up to now!!! Then woah and behild add blu fault comes up on dash, top it up still wont go off!! Took to independant garage who diagnosed tank replacement but couldnt say why or the pump. Dont really want to take to Audi and was wondering anyone else had this and any advice. Also dont know if anyone could recomend anyone in North Wales to look at it as independant garage said it needs to go back to audi as they re programme it. Any advice info appreciated abd sorry fir long message. Says wont be sble to start in 20 mikes as well????
