RS6 Air Con stuck on ECON

[chris.parcell]

Can anybody help: just recently my aircon has got stuck on the econ setting (econ light on switch is constantly on). Has this happened to anybody before and if so is it easy to sort...

Thanks

I suspect your air con needs re-charging. The unit has a failsafe to stop the air con being used when the gas is low. This is to stop damage.

might have a leak?

I have spent a bit of time looking into this and saw a message within another forum (based on A4) that said it could be a pressure sensor for condenser radiator. The cost for this part was £40 and sounded reasonably easy to fit... Has anybody heard of this? Audi wanted £70 to do a diog and said a recharge through audi would cost £100...

The first procedure is to establish wheather or not the system is low on rerigerant,because ive had a few where the high pressure switch plug has had a poor connection or even broken wires around the plug,Maybe after a cam belt change)The easist way is to do a diagnostic on the climate itself to elimaniate any electrical trouble,failing that if its a low refridgerant problem its worth have a nitrogen test done or refilled with a dye. ( its worth looking through the bumber grille look for any oily or slightly dirty patches on the condensor. to see any sign of previous leaks..Quite common!
shame you wasn't a little closer to suffolk i could investigate for you!!
