Hi all,would a bad MAF sensor cause low tubo boost,got 2 codes relating to this problem,now and again going into limp mode,car juddery at times,but ok on idle/tickover

Problem 1 if it keeps happening try a static regen if it still occurs after that then you need a new vapourizer but first check the sensors wiring is ok going into the exhaust just beneath the front seats.

Problem 2 check the MAF wiring and if ok try to clean it.

Problem 3 check for loose pipes by taking off the undercover rear part. Also check the boost solenoid is not blocked it can make a strange noise and can be found on the right side of the engine near the fuse box.

Had a new vapourizer fitted 2 months ago

I would try to force regen it then clear the error and see if it returns and if so check the sensors. It might even be due to the others setting limp mode that the regen conditions are not set so fix the easy stuff first.

Hi all,changed the MAF,still the same air flow too high,tried to do a static regen,aborts after about 14%,get the engine service now malfunction,not engine management light,hoses and wires seem ok

Problem sorted,3" split in turbo hose,took to local garage,I had given up,£400 for the pleasure,dont know if overcharged,but guy said most is labour
