Sounds like lots of things to check for the dealer. Let’s hope one of them solves the issue and doesn’t point to the dreaded control unit death. I know what you are saying Nick but I’ve been persisting for 3 years now so had enough and as soon as this is sorted it will be going into Revolutions on a SOR. Someone will get a car that has had a lot of work done to it mechanically and with my luck will probably have no issues forever more.

Can I ask if these control units are a weak point on all versions of the Aero or is it just the S1?
