Also read and post codes, I assume you are in england, or europe since you mentioned petrol and not gas. Some part stores read codes free look around. Cheap scantool would be a good investment if brother will be working on it!

You say the check engine light is on, that means the computer has stored fault codes, have them read and post them here.
