I didn't get around to changing the oil as I just gave it them back and asked them to sort as their own mechanic stated it didn't seem right after test driving. So we will see. I does drive like it needs a four wheel alignment, but that can be done later, if all else sorted.
Something else that keeps reappearing is the emissions light. Apparently, the diagnostics stated a lambda sensor and so this was replaced on one bank. Then it came back on, again suggesting a lambda sensor. It has subsequently come back on so needless to say I have asked them to look into this. The garage says it could be another sensor. Is there really four of them? However, my garage mate is more sceptical and fears something more to it and that all that is being done is a reset of the light. I did point out that the emission must have passed the test for an MOT, but I guess this can be bypassed.
