Hi , I have a 2013 sportage 1.7 CRDi , I had a problem with smoke out the exhaust and the car started to run like s##t , took it to the garage and was told we needed a new turbo , this was done at a high cost, we got the car back and it was still smoking, was told it was burning off the oil ! It never stopped so we took it back and have now been told it’s something or other that’s pushing oil back in ?? and was advised to get rid ? I haven’t got a clue what they are on about and I think I am being conned , can anyone advise me please as we are desperate
