Does anybody have a complete list of the OBDII Error Codes for the multi-jet diesel engine.

Is there a specific list for the 1.9 Multi-jet engine?

I cannot find codes P1205 and P2453 in the above list.

The engine management system is EDC16 CF39 I believe.

Code P2453 = Diesel Particulate Filter Pressure Sensor A Circuit Range / Performance

P1205 = Particulate Filter.
P2453 = Differential Pressure Sensor Signal.

I have been getting these 2 lately, and according to a german alfa forum it is most likely cracked or chewed 5cm long tubing between the dpf sensor and the dpf unit causing no pressure difference to be read on the system and throwing a fault. Will have to check it out this week and post back.

This is all very interesting - in my case I removed my DPF unit 8,000 miles ago and these errors are now permanent.

Obviously without a DPF unit there is no pressure difference. I left the sensor in place on the DPF unit. I wonder if I could duplicate the correct pressure reading to fool the ECU that everything is in order....
