So would that be pulling the plug connectors off each one and sticking a multimeter across the pins? Are there three pins per plug or two I can't remember? Well worth a try though and we didn't check that yesterday.

Agreed - it's not easy and there was some car cursing when we were refitting ETM's but was worth ruling a few things out and yes hopefully nothing too hard to fix (will take to GRN or HLM soon).
