What to check when buying one
Built from the faults above- DPF blockedAsk how it’s been used. Mostly short trips and a DPF light on the dash point to a blocked filter.
- Oil dilutionCheck the dipstick: oil above the max mark on the 2.2d is a warning sign.
- The MOT historyAdvisories noted at more than one MOT are worth asking about. Listings with a plate show the record; for any other car, look the plate up on GOV.UK.
