    EML Light/IMF again!

    Hi, hope someone can help, I've currently got the EML light on. A quick scan on a cheap vw reader shows 02547 Motor for Intake Manifold Flap (V157), Malfunction. Value of resistance too great.
    + 01254 Motor for Intake Manifold Flap (V157), Open or short to ground. Value of resistance too great. The car starts/runs/accelerates/shuts down fine with no run on/vibration when stopping and turning ignition off?. I replaced the IMF around 18 months ago along with the EGR valve(Euro car parts) because the IMF was causing poor shutdown/run on when turning off the engine. Car is a Jetta Mk5 2.0 TDI 140 BKD and as said, it runs fine. (car has now covered 82000m)

    Check fuse 8 in the engine bay fuse box.

    Any Idea as to why the EML Light is ON When the car drives/accelerates/shuts down ~ No Run On ? or should I just Replace the IMF Again??
    Cheers.

    Could you message me your re number, on some models it is not fuse 8, it is fuse 21 or 22, the green arrow, can’t remember without checking but fuse 8 normally brings up a cooling fan problem

    Fuse 24 on that version BUT if it is blown you should still get a fan controller fault code so your fault code reader may only shown OBDII emissions codes and the fan isn't one. If this 10 amp fuse is definitely not blown then look down behind the radiator behind the left hand side headlight and you will see a black 14 pin multiplug, I am seeing an increasing number of Golf 5's with corrosion damage in this plug, you are interested in the blue/red wire at pin 6 which should show 12v ignition live and continuity back to the output side of fuse 24. Also on the post June 2007 cars (yours is 07-09-2007) there is a modification to the wiring supply to this pin buried inside the harness where the wire went down 50% in size from 1mm CSA to 0.5mm CSA at a welded junction, these can corroded but finding the join will take a huge amount of work.
