Hi All,

My Ford Focus tdci 2008 is throwing up lots of error codes

P0234 - Engine Over Boost Condition

P2458 - Diesel Particulate Filter Regeneration Duration

P0340 - Camshaf Position Sensor Circuit Malfunction

P0335 - Crankshaft Position Sensor "A" Circuit Malfunction

P0087 - Fuel Rail/System Pressure Too Low

P2585 - Fuel Additive Control Module Warning Lamp Requested

P2584 - Fuel Additive Control Module MIL Request

The car drives fine.  I have had it in a local garage who said that when they took of the pump off that adds the fluid to the dpf no power was being supplied to the pump and that the car needs an auto electrician.  Anyone come across this before?

Thanks

These may be old codes clear them then see what if any come back up

They have been cleared, same code pop back up as soon as it has been started back up.

Bit of an update I found the Fuel Additive Control Module under the back passenger seat and unplugged that and all errors go away.

Could that module be faulty and can I just swap it out for the same one?  Or am I just removing the part that is telling me the car has problems?

Car ended up going to Ford.  They have said it needs a DPF Sensor and tank refill quoted me £845!

Is changing the Sensor just a matter of making sure the pipes are clear and swapping it? Or would programming be needed?

it will need the pcm learnt values reset for dpf sensor. easy enough to replace , but make sure you check the pipes are fitted correct, and if using the existing pipes just double check they are not split/deterioated.
sure you can buy a refill kit and diy.
