    Hi all I'm having a bit of an issue with my vec c gsi it has an intermittent starting problem where it sometimes just clicks as if the battery is flat on the chance that the battery isn't up to the job I've replaced it but it's no different ,also when driving it cuts it occasionaly but restarts straight away ,has anyone had a similar issue ? I'm thinking it can only be a poor conection or something as it's not bringing any lights on the dash earth possibly ?

    Sounds like a bad earth, chase the earth strap from the battery to make sure its not loose.

    Think the earth goes under and attaches to the gear box housing and oil and crap get under the fitting mite be best removing it and cleaning where it makes contact

    Well the plot thickens ,I've stripped and cleaned the earths I could find in and around the engine bay tried them dry and laced with copper slip to no avail,however I sat for a few minutes tonight with the ignition on 2nd click and I noticed when I press the accelerator peddle the engine management light goes from static to flashing intermittent ,not quite sure what to make of that ,this must be a common issue that these gsi's suffer I've read a few threads where people have posted exactly the same symptoms as I have but as of yet I've not seen if anyone has got to the bottom of it

    Yh as samson said as if it flashes like morse code that means u have fault codes stored having the key on ignition with lights on and pressing throttle does the pedal test to check for fault codes if you do it again and check to see if you have any codes stored

    Tried it again today and it didn't do a thing no lights ,with it running I've repeatedly blipped the throttle the same as I did last night and the car cut out I started it again no problem and did the same and it cut out again ,,be unplugged the peddle and plugged it back in as all the connections are clean and double checked the earth on the steering column ,now I don't seem to have any issues at all it starts good although I've not taken it out for a drive yet ,I wonder if it's worth trying a different peddle I can borrow one from a lad who is breaking one that was running with no issues

    When the eml was flashing it was more like a poor conection rather than in any sequence ,the spanner light came on also

    That means there is a fault somewhere then.
    turn the ignition to postion 2 so all the lights come on and press the brake pedal and throttle at the same time and hold it there and the eml will flash the fault codes if it flashes continously then there is no codes present if it flashes and pauses for a second then flashes again then there is codes present and u need to count the flashes to get the codes

    it all seems to boil down to the motor that controls the butterfly in the throttle body it would appear that breaks down and that’s been causing the cutting out
