    Road Speed Sensor

    I thought i would post this tip..

    My car has a 20v turbo transplant and when the lights are on i.e. electrical load it used to suffer from occasional stalling when pulling up at lights etc.

    I put it down to how much i have lightened the bottom end.

    However having studied many pages on here and elsewhere together with VAG COM indicating 5 kmh when stationary, it appeared that it could be down to the road speed sensor not being connected. as a consequence i made up a short loom to connect/convert the old ur one in to 5v and connected the appropriate signal to the ecu, pin 50 in my case. Hay presto no more stalling and a smother tick over.. Simple job to, don't know why i didn't do it before..

    Thought it may come in useful for other converters..

    I can't remember wiring that up on my UR, must have as it never stalls, however my RS2 after along run mostly motorway always stalls at the next atempt at tick over, restart and ticks over spot on. Perhaps a its similar cause. nothing on vagcom.. I will have to have a look one day when I get chance.
