Hi there can anyone help me please my golf has no power at all like the Turbo isn't kicking in at all there's no smoke at all I've checked the maf its brand new however when I checked it the lead you plug into the maf only has four pins five holes but the maf unit has five pins so don't know if this is right. I tryed the n75 valve swapped it round with the egr valve same part number but still the same. And when the engine is ticking over it sounds fine but when you rev it its really loud but its not the exhaust and I checked that the injectors were not loose can anyone help me please there is no management light on either although I don't know if anyone has disconnected the bulb cause when I unplugged the maf the management light did not come on and when I unplugged the maf it made no difference thank you in advance.
