Just had my a/c serviced. They reckon the gas depletes after two years. They valeted the car as well.
Apologies for going off topic, but if the dealer was going to valet my car as part of an a/c service, that would be a good enough reason for me not to get the air con serviced!
The standard of VW dealers courtesy car washes is pretty poor IMO; usually a very poor washing technique - a single bucket of water that’s been used on the previous service washes (so the water can be quite dirty), and a gritty sponge, and dried with a dirty chamois. The perfect recipe for inflicting swirl marks on your paintwork.
When my car goes into the dealer for servicing or warranty work, I put my ‘please do not wash this vehicle’ hanger on the rear view mirror;
I also tie a ‘do not wash’ tag on my keys and get the same instruction added by the service advisor to the worksheet.
Overkill? I don’t think so. My car goes into the dealers with clean, swirl-free paintwork, I don’t want complimentary swirls added by the dealers sponge monkey! ?
