    More issues are adding up!

    Hello everyone,

    The S3 seems to have a new illness every single day, latest issues are puzzling me:

    The speedo dies and I can't even read it from the climate control!

    VCDS: 16885 - Vehicle Speed Sensor: Implausible Signal
    P0501 - 35-10 - - - Intermittent


    when the above happens car feels extremely sluggish, hesitant and feels like it running on 3 cylinders after 2k rpm.

    The second issue is the fuel gauge moves up and down by 1/4 of a tank! one second the range says 0 miles and next second it goes up to 80 miles!

    I am thinking another coil or two might be on their way out. how do you measure it on vcds? I used block 026 and had very different reading at 3k rpm: 3v 6v 1.5v 2v respectively?

    any help is appreciated.

    S3-8L REVO stage 2, Milltek, 3" DP & custom 3" decat, RS2 spark plugs, 4 bar FPR, Green-Cotton uprated upper/lower boost hose & TIP, Front Zimmerman & Ferrodo. LCR spliter. boost gauge, smoothed AB. Aero blades, H&R 5mm spacers. Best time 14.03sec, 0-62 in 5.7sec. 207gs @ 25psi , polished inlet mani. VAGCOM 805.1

    Check for stripped wires in the engine bay my reverse switch had 2mm of cover stripped this caused a short and my speedo to stop working and my fuel gauge to read randomly.
