Has your rev counter and ABS stopped working too? Any worrying lights on the dashboard? First, try an ECU reset, see if that 'resets' the problem.
ECU reset: Disconnect battery for 15 minutes, reconnect battery, turn key to MAR (ignition lights on but not running) for 90 seconds, turn key to OFF for 90 seconds, Start car without touching the throttle and allow it to Idle for 5 minutes, after that you need to go for a drive, 5 minutes easy on the gas and another 5 giving it a bit more of a push.
If that doesn’t work, try checking the ABS sensors, and at the same time check to see if any plugs are loose or contaminated. There is one particular earth lead that is under the filter box, next to the cooling tank (I think – yours is a lhd GTV, so might be the other side….), check that first.
If your ABS is not working, and none of the above fixes the issue, then your ABS module might not be working…. Hope not though!
