Upon further inspection the light unit was corroded and weirdly still illuminated but also sent a fault back to the car.
We have an issue as well with the light warning light where in it displays that a light is out but all the lights are actually working. We just put up with that, has been ongoing for about a year. Though it might be worth me checking out the lights to see if I can fix that problem too. Cheers.

After that suspect the Oil pump before going to problems within the engine ,hope this helps
To be honest I don't know. It's always been serviced when it should and taken in ASAP for any warning lights etc... I'll get them to check as they have serviced it for the last 3 years.

It doesn't come on from cold. Just random times. I think I had the engine running for about 10 mins the first time. And on the way into the garage yesterday it must have come on within about the same time I guess. There's no noises that are out of normal.

I'll call them tomorrow and ask what they have tried and checked etc... If I get anything back from them I'll report back here.

I don't want to get rid of the car as we've looked after it and we like it. I'd much rather get it fixed if possible. Fingers crossed.
