Hello - and Welcome..

My name is MIKE - it would appear that the previous person that replied to you has now opted out of this question without letting you know - so I can help you from here..

Before we progress - can I just ask, have the fault codes been read... and if so , what are they?

Too - what sort of garage is doing the diagnostic checking for you ?

Also - please give me the cars Full reg number - and what is its service history like ?
