Singapore car repair guide

BYD Dolphin: Aircon weak / cabin takes long to cool

If you are seeing this symptom in Singapore, use this as a pre-workshop checklist. The goal is to identify the likely root cause, avoid replacing the wrong part, and know the fair repair range before approving work.

Fair SG range
$80–$400
Red-flag quote
$1,200+
Likely fix
Cabin filter, refrigerant leak check, thermal-management scan

What this usually means

Dolphin aircon complaints can be cabin filter, refrigerant, compressor command or thermal-management software before compressor failure. Ask for EV-safe aircon pressure data first.

What to ask the workshop before approving repair

  • • Show the diagnostic fault codes.
  • • Show photo/video proof of the failed part.
  • • Give an itemised quote for parts and labour.
  • • Explain why cheaper common fixes were ruled out.
  • • Use/confirm: EV-safe aircon service equipment
  • • Use/confirm: EV diagnostic scanner

This is not a final diagnosis. It is a money-saving checklist before you go workshop.
