However, I had a chat with Nick at Austin Garages and he suggested I check out the ECU (Engine Control Unit) for water damage, so I did that and lo and behold, there are marks in the ECU which indicated it's been wet at some point.
So what I've done is sent the unit off to ecu-doctor.co.uk for them to check over and repair. I'm hoping that when it comes back the problem will be gone.
A few weeks ago at the recent Nano meet, Duncan checked my car with his T4 (Testbook version 4.Computer Diagnostic System) (thanks Duncan). It didn't find any issues with the ECU, but it did flag something up for the glow plug relay. I suppose it could have been damaged at the same time as the ECU - seeing that they co-habit in the same enclosure.
I'm worried now that if my glow plug relay is faulty, it could damage my recently refurbed ECU. Is this possible do you think? I could replace it, but don't want to splash out on the part if it's not necessary - they're Ã‚Â£80 from Rimmers.
The car starts OK by the way, so I've never suspected any glow plug issues. I suppose the glow plug relay error could be caused by a dodgy ECU?
Any comments or advice greatfully received!!
