Re: OBDII Codes for Multi-Jet 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.

Re: OBDII Codes for Multi-Jet Engine

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.

Question Re: OBDII Codes for Multi-Jet Engine

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....
