So just removed the MAF and attempted to clean with proper cleaner , also removed the n75 valve and cleaned some dirt removed from both items re plumbed back in started the car all fine except the friggin traction control light now on as well as the Engine check light.  Have disconnected the battery for 20 mins to see if that clears the faults and lights anyone got any ideas on why this has happened????? Get ****ed now !!!

So nearly 5 hrs working on the car new MAF purchased £110.00 euro car parts bosch remanufactured unit fitted and traction control light off now and staying off I hope.  Also engine management light off too for now how long who knows??? Also checked all PCV hoses under the manifold cleaned and replaced new clips oh and a new air filter too!!!!

 

Engine idles fine revs cleanly but still no turbo boost???? Air is being sucked in to the diverter valve hose on the top when removed sucks at your finger and can hear the diver valve click when I  're attached the hose on the top so I assume that's good ?? Must be some pressure there now.  Also checked throttle body to intercooler hose and gave it a good clean and tightened the clips so that's all ok now.  Took of the n75 and cleaned this too.  Blowing through the valve it's aĺl clear and good pressure.  So now I guess it's time for a vag com scan
