The fault
How you spot it
The timing chain stretches from 80,000 kilometres, and the cause is the exhaust-side chain tensioner: it is undersized and does not hold the chain properly. Short city use speeds the process up.
The symptom is a rattle on a cold start. The stretched chain makes the timing slip, and if the chain jumps, the valves and the pistons meet.

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.
