The fault
How you spot it
On the T-Roc diesel the AdBlue system fails and the particulate filter blocks, and the warning light stays on. Short urban use speeds both up, because the filter does not reach regeneration temperature.

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.
