This has been a super useful thread.
Just booked my GTS ST 2yr service with Colchester, £600 including blake fliud flush. The service advisor said the brake recall (which I have just had done by Hatfield) only bleeds the brakes a little so isn't a full flush by any means.
Saved £200+...
I had the same set of messages as OP had. Also had camera issues (intermittently various cameras not working) and dealer thought perhaps linked. The camera system is now scheduled to be completely replaced.
I have a very similar spec ST GTS and had a rattle from day 1 - turned out it was the 2 part rear parcel shelf. The two sections need to be pushed into a snug fit, else a little rattle. Simple to fix and fully sorted!
Dealer said to me that they were having to give all prior allocations to customers ahead of me who were getting delayed by the heater issue and hadn't got the car yet. Said that the factory had stopped issuing new allocations.
I am going to try phoning around and see if other dealers are saying...
Arrrgh! I was given an allocation for delivery June 23. Dealer just called to say that due to heater issues the allocation is cancelled and now delivery likely "sometime" in 2024.
Give me strength
