Right ive had the sai incorrect flow code n now maf code n also esp mk60 code abs front sensors + engine control moduale summit dtc etc. I cant believe they all come at same time!!? I had the maf off to clean as i thought it mite help with the ibcorrect flow issue n put it back in. So once back in these other codes came up with the esp light on , tryed to erase codes but light staying on with maf still an issue . Not sure wats causing these to happen. Also i thought i would check that the sai pump was working so i pulled the 100 relay fuse to jack the socket with the inlet hose disconnected next to maf meter but that didnt even flicker (not sure if i did it right )surely the pump would blow air out of that pipe ?the car was on idle aswell . Hope the pump aint gone aswell seems to be having a fookin party of its own at my expense!
