Hi guys new to the forum and to audi and I am in desperate need of help, I brought the car less then 2 months ago I've already spent over 500 pound on the car, with the car having a new turbo and full service history I felt I had a strong chance of a strong reliable car so I bought the audi a4 sline on a 55 plate being 19'getting this car was like winning the lottery compared to my treved up astra i had before hand but the audi is equipped with a blb engine(now knowing the blb engine is the worst sort). Firstly my pipe split between the egr cooler and the egr valve £85+vat then a pipe comming off the egr cooler split can't get one from anywhere except audi and they charge £350 including vat and then I have to pay for labour because personally I'm not great with mechanics, so I got that sorted bit my tounge and paid out for it hoping it would be the last for a little whole, mistakenly thinking my new audi would be reliable, so I was leaving brandshatch on Saturday to make my way home and as I start it the car is ideling funny and I stall the car I accepted it the first time but after the 3rd time I knew something was wrong after many revs I managed to get driving the engine warms up and seems ok I then notice a loss of power below 2.5-3 revs and whilst heavily putting my foot down to solve this I am getting a lot of thick black smoke from what I can see in my rear view mirror so I'm getting flashed by the other drivers I stop accelerating and sit at a steady pace which is easy to do with no black smoke I couldn't get to a garage the past couple of days seeing as I've been working so leavin for work this morning I decide ill rev the car before leaving and when the car is cold I doscover recon the car it gets very lumpy at 2000 revs and struggles to get past it.Apologies for the long post I hope someone knows what's going on and. An help me it would be much appreciated if in need of any more ingot please don't hesitate to ask thanks Stephen
