Mercedes B-Class: Aircon weak / not cold in traffic

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
$150–$800
Red-flag quote
$1,800+
Likely fix
Aircon leak test, condenser/fan diagnosis, refrigerant service

What this usually means

B-Class aircon issues in Singapore are commonly refrigerant leak, condenser, cabin filter or fan-control faults before compressor failure. Ask for pressure readings and leak-test proof.

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.

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