    Got my A4 2.5 TDI chipped by Upsolute. Runs fine but at about 1900rpm if i lift off gradually in gears 3-5 the engine makes a strange 'metallic' sound. Upsolute engineer cant say for definite but thinks it may be the diverter valve.

    in 6th at the same revs the engine stumbles/hesitates

    Neither of the above happens with the standard chip.

    Does anyone have any opinions, only i was told by someone else that diesels dont have diverter valves?? /ubbthreads/images/graemlins/confused.gif

    Its probably the EGR valve operating - you normally hear a small pssh when changing gear
