:welcome2:
First off, you need to get hold of the EASUnlock Software and Connection Lead....
You would have to obtain the lead or make one and The Software is free from RSW Solutions, or alternatively the best solution would be to contact a member on here called Datatek, for the princely sum of around £11 & p+p he can kindly supply the Software and a manufactured, tested Lead.
Once you have this to hand, you can plug in the lead and read the fault codes from the ECU....
Unfortunatly without knowing what has caused the fault, we could be flying blind.
Luckily if it hasn't sunk to the bump stops, things *might* not be to bad and might only be a height sensor or a pressure switch....
(Also, put your location in as there may be someone local to you who can help for the hugely extortionate price of a bacon sandwich and posh biscuits)
Again without the fault reading....its hit and miss.
I don't think you have bought a lemon (depending on fault codes..!!) as the RR P38 EAS is a weak point of what is otherwise a great car....
The Wammer and Datatek are geniuses on the EAS system, but first Contact Datatek for a lead and software....damn sight cheaper than you can find on Fleabay or elsewhere....
