Hello, Im looking for a bit of advice. My car is a C3 II 2010 model 1.4 hdi with 82,000 on the clock. Yesterday I started up the car, everything fine but a message appeared 'Anti Pollution Faulty' and the light came on the dash. I got home and looked at the error codes, it came up with P1162 and P1351. I cleared the codes of the ecu. I started the car a few times throughout the day all with the coolant over 20 degrees, nothing wrong. I started the car this morning with the coolant at 13 degrees and the error code P1351 came back on the ecu. If anybody has any thoughts/previous experience please let me know. Many thanks Will
