Hey mate,
Checked with the lad who did it and the error code was ABS sensor - Short. I'll post the exact code when I go round and hook it back up on Friday. My mate said he checked the loom going into the engine bay and it looked ok? For 4 yrs I've had an intermittent issue where the lights would come on but then disappear when you turn the engine off and back on but since last week it has permanently been on :-(
