2.0 CDTI (A20DT* / B20DTH): DPF and EGR coking

expensive

The Insignia and Astra 2.0 litre CDTI (A20DTC/DTL/DTJ/DTH/DTE/DTR, later B20DTH) is a diesel. If it warms up regularly, the particulate filter regenerates. The three common faults are: DPF blocking on short trips (no regeneration), EGR coking (loss of power, rough idle, occasionally limp mode), and at high mileage injector imbalance.

Show the rest

The timing belt interval is 120,000 to 150,000 km or 6 to 10 years.

If the car only ran in town, the particulate filter can block because it does not regenerate, and the EGR cokes up.

between 120,000 and 220,000 km

What to check

  • Ask for a full fault code read: DPF differential pressure, EGR, injector correction
  • Try it on the open road: is there limp mode, loss of power, a DPF light
  • Ask whether there was a forced regeneration, an EGR clean or a DPF replacement: ask for the invoice

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.
