πβ‘ Peugeot 508 Hybrid β High Voltage A/C Compressor Replacement β‘βοΈ
This Peugeot 508 Hybrid came into the workshop with a rumbling high-voltage air conditioning compressor that had become noisy whenever operated.
Working on hybrid and electric vehicles requires the highest level of safety.
Before any work began, we:
π§ Cordoned off the work area and displayed high-voltage warning signs.
π¨βπ§ Ensured only authorised technicians were permitted in the area.
π Followed the manufacturer's technical procedures step by step.
The vehicle was then safely isolated by:
π Removing and locking out the high-voltage safety interlock.
π Disconnecting both 12V batteries. β‘
πDisconnecting the traction battery's main high-voltage connectors. β‘
β
Carried out dead testing to confirm the system was fully de-energised before any repairs began.
With the vehicle safely isolated, we replaced the faulty high-voltage A/C compressor, fitted new A/C pipe seals and then recommissioned both the high-voltage and 12V electrical systems.
βοΈ The air conditioning system was placed under a deep vacuum to remove moisture before being recharged with the correct quantity of R1234yf refrigerant.
After thorough testing, the repair was a complete success! π
The air conditioning is now operating smoothly and quietly, with the rumbling noise completely gone, leaving the customer with a cool, comfortable drive once again. πβοΈ
At our workshop, safety, quality and following manufacturer procedures are never compromised, especially when working on hybrid and electric vehicles. β‘π§
