The fault
How you spot it
On the N43 direct injection four cylinder the plastic guides of the timing chain can break. The broken pieces fall into the sump and block the screen of the oil pickup. From then on the engine is starved of oil, and that takes out the bearings first.
If the chain is rattling, the debris may already be on its way to the oil pickup, so leaving the replacement for later is not enough.
On the same engine the injectors, the ignition coils and the NOx sensor can fail too.

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.
