The fault

How you spot it

The injector does not close fully, and with the engine standing fuel drips into the cylinder. The symptoms are hard, long cranking (mostly after standing for a while), smoky first minutes, a hesitant idle, and dilution of the engine oil: the oil level goes higher, it smells of petrol, and the diluted oil lubricates worse. It shows up on cars built between 2018 and 2020.

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.
