Singapore car repair guide

Mercedes E-Class: Aircon not cold / Weak cooling

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–$350
Red-flag quote
$1,500+
Likely fix
Drain unblock + refrigerant recharge

What this usually means

This is 90% likely an evaporator drain blockage or refrigerant top-up ($150-350). Agent sometimes pushes full compressor replacement ($1,800+). Always start with a leak test + refrigerant level check before any compressor work.

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.
