Breaking wiring harness under the driver's seat: airbag light

critical

The wiring harness running under the driver's seat kinks and breaks from the seat being adjusted. The sign is the airbag light staying on on the dash. With the airbag light on the system will not work in a crash, and it fails the roadworthiness test too. The part is cheap, the fault finding is the expensive bit, and many sellers mention it as "just a light".

What to check

After switching the ignition on, watch whether the airbag light goes out within a few seconds
Slide the seat fully forwards and backwards, and watch whether the light flashes up
Look at the wiring harness under the seat: broken insulation, chafe marks

Door seal: water in the front footwell

expensive

The door seal ages, and the water runs into the front footwell. It stays in the foam under the carpet, so for a long time only the misting windows and the musty smell show it. The comfort control unit and several connectors run in the footwell: if they corrode, the fault is electrical from then on.

What to check

Lift the front carpets and press the foam on both sides
Run your finger along the door seals: hard, cracked rubber is porous
Smell the cabin when cold

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.
