Just to update everybody of my misfortune lol
I took the 350 to Ancasters of Croydon. I phoned them up and the main guy in the service department said "come down and talk to john, he should be able to help"
I thought great!! Maybe he'll do something there and then to help. I drove 45 minutes to meet him. He looked at my car for 1 second and said yep you'll need to book it in!!!!
he could have told me that on the bloody phone! anyways
i had to wait nearly 2 weeks before they could fit me in. I took it down yesterday hung around in croydon for the day then at 3.30pm he calls me up and says they won't have time to do it today cos all but 1 of the mechanics have gone home! so you better leave it overnight. (eveb tho when i retuned to the garage to get a courtesy car i counted 4 mechanics hanging around, including 2 working on MY car!!
Cut a long story short i wasn't impressed with the way they ran their business.
Picked my my car today and they said the exact same thing as the 1st place i took it too. It needs a new ABS unit. Costing £3,500, plus £200 to fit. But i have to order it but it won't be available till mid July! Guess more 350's are getting this problem!
