Service detail

Climate systems serviced as carefully as the engine.

Modern prestige cars run two refrigerants, two evaporators and an electronically commutated compressor. We service the system the way the marque designed it — not as a bottle-and-go recharge.

Recovery and recharge equipment connected to a luxury vehicle

What we do at every visit

  • Recovery, vacuum and recharge for both R-1234yf and R-134a refrigerants
  • Calibrated weight measurement, with a printout of the recovered, vented and renewed quantities
  • Leak detection by UV tracer dye and electronic sniffer
  • Evaporator cleaning and antibacterial treatment for cabin odour control
  • Compressor electronic coding and clutch-air-gap adjustment where applicable
  • Cabin filter renewal with the marque-specified part number
  • End-to-end functional test on dual-zone, four-zone and rear-roof climate panels
Common climate complaints

What we typically see

Slow cool-down at idle

Often a tired condenser fan or a partially blocked condenser. We measure subcool and superheat across the system before recommending replacement.

Musty smell on first start

Biological growth on the evaporator. A two-step ozone and enzymatic treatment usually resolves it without removing the dashboard.

Compressor cycling rapidly

Refrigerant charge drift, an O-ring leak or a tired compressor control valve. Diagnosis takes about an hour.

Climate display freezing

Common on certain BMW and Mercedes-Benz platforms. Usually a software update on the central gateway, occasionally a CAN-bus issue we trace by oscilloscope.

Refrigerant note

Why we recover, weigh and document every gram

R-1234yf carries a much lower global warming potential than its predecessor, but it is also four times more expensive. We use a dual-refrigerant station that records the recovered weight, the renewed weight and the vented oil — every print-out is signed and attached to your job record.

Topping up "to feel" is a habit we do not have. If your system has lost charge, there is a leak — and we want to find it.
