99 1.9tdi 110bhp AFU has suddenly lost its umph & developed a very harsh diesel knock under acceleration.
First diagnostic check showed MAF faulty but new one didn't cure the problem only clear the code.
Tried a different diagnostic test & that showed up 2 codes & one was throttle pedal sensor & the other cold start injector.
Any ideas as i was thinking on the lines of the variable turbo veins stuck?? & the ECU telling the pump to give it the fuel it would normaly need causing the diesel knock??
Starts like a dream with no smoke even underacceleration & ticks over sweet as a nut but a little harsher than it used to.
