Light stays on if theres a fault in the diagnostics. Ie faulty or unplugged sensor. From experience on an audi a4 when you remove the bumper to change a cambelt you need to unplug the pressure switch and if its not put back or in properly it throws the light. I assume itll be the same on your car. Id suggest a faulty sensor is probably the issue.
thx for that info it was workin fine upto a wk ago don't want to take front end off though can I get to sensor with out doing that
the diagnostic came up with a faulty high pressure sensor on air con will be gettin that sorted soon as I can afford it
Ive just fixed mine after a year of no a/c
NEW SWITCH - CORRODED OLD ONE
SECOND HAND PUMP - CLUTCH COUPLING FAILED
NEW CONDENSER - LEAKING
there are a lot of different switches out there and up to £50
some tips:
don't thread the switch on without supporting the condenser port with a spanner (might bend it)
the older B6 pump fits all you have to do is swap the ports over from your old compressor (2 screws)
get a professional to evacuate and regas for £35
make sure all the fuses work there is one that just does the high pressure switch
