Hi
We have a 2005 307 1.6hdi which has the engine cooling fan staying on after the engine has been turned off, also the power is down (have to change down up hills etc). Yesterday the anti pollution message appeared along with the EMl. I have connected planet and got the following perm faults:
1) EGR circuit air flow measured higher than the ref value
2) particle filter. Particulate emission filter overloaded
3) heater Circuit relay...

I have tried a forced regen but I get the message 'forced regeneration impossible'
Any ideas?

Yes, check the parameters measurement to check points 1 and 2.

Do a components check on the fan and relays for point 3.

No fan working = no regen = blocked filter.

Hi
I have checked the fan relays and both work from the laptop, the fan comes in when the engine is switched off (occasionally whilst running)
I also checked the additive pump etc, no problems
How do I check the parameters for 1 and 2 (what am I looking for)?
Thanks
