I have an S plate 110bhp tid sharan.

In 2004 Ac button flashes on ignition then goes of. System was regassed and dye added. It was then retested a week later and degassed, bumper removed and new pipe from expansion valve to low pressure connector - regassed.

In 2008 air conditioning not working, regassed and dye added, leak found from high pressure pipe. Removed parts and replaced, then regassed.

In 22nd January 2009 Air con not working, checked at VAG on diagnostics which showed 1 fault on air blower, evacuate and regas of system.

Yesterday came to use and nothing at all. For the past few months the dispaly unit flashes when i put key in ignition.

Can anybody please advise what they think i should do next and waht the problem may be. I have 3 kids under 4 and unable to use car at the moment.

Thanks

David
