The fault
How you spot it
With the air conditioning on, a whistling noise comes from the dashboard, and the cause is the expansion valve, which meters the refrigerant, so the compressor has not failed and the gas has not run out. Most places first suggest a recharge, but a recharge does not stop the noise: the noise comes back, and you pay for a recharge that does not help.

How we know
Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
