Will do, thanks! :thumbsup:

I have inpa but not really sure how to work it :oops:

I have the below when I go through error memory. I have no idea what any of it means.

I had these exact 2 lights come on and then around 5 mins later the battery charge light came on. I took the battery out and charged it put it back in the car and cleared the faults (it was showing pressures sensor) and it ran faultlessly for a week just doing odd little runs and then the same thing happened again.

This time i checked the alternator and it was only putting out 11.17V so charged the battery again cleared the faults and took the car down to the garage who confirmed the alternator was indeed NFG. So one alternator swap later and everything is now fine and the car has run for a few weeks now with no more sign of the warning lights, it could be pure coincidence that this cured it but if you have this fault my advice would be hook up the multi-meter if you have one and just have a check

Had the same two lights on my dash last Sunday. It was suggested that a slightly depleted battery may have triggered it after some work on the car necessitated a few hood operations without the engine running. A decent drive home (ie charge the battery) didn’t make them go away, but a few minutes of the battery negative terminal disconnected did. They have not come back yet. Half expecting it to happen again and if it does will suspect a pressure sensor.

I had the DSC telltale and the exclamation mark light up recently when touring Dartmoor, it was during our recent heatwave and it seemed as though it was only happening on days where the temperature was up around 30C.
That would make a good smoking gun, however my battery has died and needed replacing since then.
