Thank you for your reply, am about to try this. Sorry, if the answer is obvious but what do you mean by "contest Bart with volt meter"? Many thanks.

I don't think you should do that , better get another opinion , at any rate now you know that modern cars with all their electronics should not be giving jump starts , like many other things in todays world they can't handle adversity

Error code for airbag/restraint systems have now gone but a system fault for the DSC system has now appeared. Frustrating.

Attempted to clear clear the DSC fault with an OBD device. It kept returning until I cleared it and then drove the car a few 100 metres. Let's hope neither fault returns. Many thanks for your help. Happy motoring.
