Hi peeps

 

Switched my air conditioning on today and all was fine. Suddenly loud groaning and vibrating sound and sounded like a bag of bolts knocking under the car! Switched it off and all was fine..car ticked over and drove smoothly and quietly. Now everytime I switch my heater on it rumbles and vibrates. Switch it off and everything fine. Car drives great still but can't demist the car and it's a nightmare! Any suggestions as it sounds like the engine is gonna blow up when I need my demister/air con!

Thanks in advance.

It sounds like the air con pump is going? If you can get it off the car there is a label on it with the part number. Secondhand one from the for sale forum or new from courtesy parts.

if you press the ECON button does the noise go away? IF it does then its a compressor problem

sounds like magnetic coupling in the pump.

if it makes noises, disengage immediately and try again; it will probably engage properly next time.

Coupling costs 350 euro vat included

cheers
