Hello All, I took my 2011 audi a1 1.6 tdi for the emissions fix in April of this year (2017) it was in perfect working order before I let them butcher it. Within 3 miles of driving it away the engine light came on and the glow plug light started blinking. I pulled over restarted the car and it was ok but it happened again before I got home. I rang audi immediately they said they would call me back the next day which they failed to do anyway 2 months later in June of this year it went into limp mode it' been like this ever since. I had a diagnostics done by a firm who deal with audi,Skoda,vw etc they said it was the egr valve and cooler also possibly (maf sensor which I replaced at a cost of £118) so it couldnt be the maf because its brand new. Anyway they quoted me £540 to get the egr valve and cooler sorted this is money i dont have i bought the car at 5 years old and still have 3 and half years to pay it off. Of course audi claim its not tge fix thats caused it but the car was perfect before they touched it im sick to death of this heap of crap im now stuck with its causing me unwanted stress and im literally throwing my money away im at my whits end with it I should have stuck with the old banger I had before buying a "reliable well built car" what was a dream to drive is now depressing every single second I'm in it. They shouldn' have lied in the 1st place I think they should repair it for free
