Hi went to write this last night but somehow managed to delete it
i recently bought a vauxhall zafira 1.9 cdti 150 and have had it remapped due to previous problems of the dpf being blocked and really bad mpg ie 32
it was done by midland remaps who did a diagnostic on the car first and said that there was 2 Fault codes,one was relating to the dpf fault and the other was related to low boost pressure or something along those lines.I did the DPF removal as promised along with the deletion of the reGen mode and the deletion of the EGR valve.
once this was done he took it out for a test drive and came back saying that one of the original codes to do with the vacuum leak would not go out and it was causing the turbo to Stop boosting over around 2.5k to 3k
i can tell you all the other little fiddler bit afterwards as this is taking up too much space but the short of it now is my mpg isn't very good still the turbo makes a whining noise like a police car which i've been told is now due to their being no back pressure as there is no dpf internal and when the turbo is pushed it makes a weird Warbling noise and get a dump valve chatter when changing gear along with the code p2279 air system intake leak
got it booked in at puma build birmingham For the diagnosis but i would really appreciate any information given to save my time and cash
