Econ Button wont turn off

Anyone know a fix?

Econ stays on for a number of reasons, it protects the system when theres a fault.
Get a re-gass first.

Hi,

There are quite a lot of threads covering this topic on the B6 / B7 A4 forums (and A6, A8 etc which use the same aircon system). Have a search, but in short; it could be a fault with any one of the following

• The system needs re-gassing (hope there isn't a leak somewhere!)
• The pressure sensor (behind the passenger headlight) is faulty and needs replacing (a very common reason for the ECON light being stuck on)
• The compressor is faulty and needs replacing (£Ouch)
• The condenser is faulty and needs replacing
• The evaporator is faulty and need replacing

Hope that helps
Al.

I bet it needs a re gas as to be fair the Aircon was **** poor. I'll let kwikfit have a go tomorrow as see if that helps.

I've got the same problem, took it to Nationwide Autocentres to get a full aircon service and regas, but they said that their automatic gassing system would not start as there was a fault! They didn't have time to find out what was wrong, but I guess I need to find out if it is any of the other items listed.

How would I find out if the pressure sensor is faulty?

scan for faults with VCDS
