Re: GT Parking Sensors - They've died :(
Well mate when it comes to body controls I have been there done that, bought the T-shirt and written and directed the play. Mine started with all the same problems as you, I am awaiting my 3rd one at the mo, and I have a GT as a loan car. If you want my advice you need to speak to Daniel at Alfa on 0800 718 000 and tell him your car is exhibiting the same symptoms as mine. You will have to be a little insistant and if you read the other threads I have posted on it you will see how insistant, but you will be able to get one. Don't expect a quick fix and I hope you have your security codes. As for dealers I would say E S Jones in Dobshill, as they have plenty of experience, but its a bit of a way to go.
Good luck, if you need any other info just ask, I have lots
