Why the recharge Shelly? Stopped working or just not as efficient? Make sure they do a leak test
I’ve had the car for 17 months and it’s never worked
So I just thought it needed recharging
Thank you for asking me that question, I’ll ask them to do a leak test first and I’ll let you know what happens

Shelly most of the modern air con machines are like a washing machine they have 4 cycles.
1. Drain
All old gases and oil removed.
2. Vacuum.
The system get put into a state of Vacuum usually for about 20 minutes.
3. Leak.
System then gets leak tested takes about 10 minutes to make sure holding the Vacuum.
4. Charge.
If all checks passed then system will be filled will new oil and gas.
After this if system full again and aircon turns out not working there will be a mechanical issue ( compressor fault) or electrical issue ( sensor or wiring fault)
But I'm sure it will just never been gassed and low or none left.
If it fails the leak test it will need a dye test ( where an amount of gas with a uv dye is added system ran to locate leak with uv lamp then system drain again.
If it does have a leak most likely place will be the condenser at the front they can get hit by stones etc through the front grille areas.

Sorted out the air-conditioning on my Z3 today. Roof down, that's it done.
A bit late now but if it didn't work when you got the car that was the time to take it back and have it put right.

Did you have it regassedSorted out the air-conditioning on my Z3 today. Roof down, that's it done.
I got my Z in the October, so I didn’t use the air conditioning until about 8-9 months later , I didn’t think about trying it when I brought the carA bit late now but if it didn't work when you got the car that was the time to take it back and have it put right.
