Hi can anyone confirm that if I disconnect my battery I will not loose the revo map, had the car mapped yesterday stage one on a golf gti mk5, the ecp light comes on intermittently and the car goes into limp mode, if I turn the ignition key off then restart the car all is fine for a while then the light comes back on and back in limp mode,
I have been advised to do this
epc is related to throttle etc hence Electronic Power Control
so more than likely to do with DBW, see what code is in it but for the time being dissconnect the battery (make sure you have the radio code), re-connect turn the ignition on(leave on for 30sec or so) then start the car.
This will have done a TBA which eliminates one potential factor!
Thanks in advance
