Citroen Xsara Picasso Ecu

[Mazzer]

Hi everyone knew to this forum and I need some advice please, I needed a new clutch fitted on my Citroen picasso year 2000 so took it along to a mobile mechanic ,clutch was fitted okay but when he tried to start the car it just wouldn't go, anyway to cut a long story short, after 2 days of fiddling with electric wires earthing them etc he eventually got it started and some things working except the most important thing as I live in spain ,My Air Conditioning, the fan works fine but not the aircon, so we came across a this website www.the-ecu-doctor.co.uk apparently you send your ecu to them they diagnose the problem and then its up to you if you have the work carried out the price for a standard rebuild is £120 plus parts which doesn't sound too bad. My question is this, has anybody had any dealings with THE ECU DOCTOR before I go to the trouble of sending mine back to the UK etc. Just not sure what to do whether they are trustable or not any advice would be very much appreciated.

Thanks
