Hi All,
On my drive to France last week the engine management came on, this happened when accelerating away from the toll gates. There was obvious loss of power or anything else but the cruise control and A/C was not working.
Once back home my laptop for diagbox played up but I eventually got the following codes
P1445 Additive adding ---- The quantity of additive injected into PEF has exceeded the max threshold. PEF must changed.
along with P1496, P1497 P149C Variable resistance turbocharger
P0234 Charge Pressure regulation
I suspect they are related.

Re: c5 x7 fault codes
Hi Kenny I can't locate your VIN, so if you can provide that I can look into the specific codes for your engine.

Re: c5 x7 fault codes
Ok, so basically P1445 is telling you that the filter is at the limits of the unburned Cerine that remains in the particle filter.
Additive injected into the fuel system over time to lower the combustion temperature for burning of the particulate matter has a downside. It contains Cerine which contains elements that cannot be burned off and these remain in the particle filter, leading to its eventual blockage. The engine ECU records the amount of additive injected since the car left the factory (and whenever you refill it when resetting the additive counter to zero). This is recorded in grammes. A weight - to mileage table is used to estimate the amount of Cerine dumped into the filter based on distance travelled. So you have probably reached the upper limit. How many miles have you done?
Here are the faults codes and likely suspects:

Re: c5 x7 fault codes
Marc,
Mileage approx. 151,000miles, top up additive approx. 18 months ago.
So, having PEF deep cleaned or replaced would help ?
This one has me scratching my head.

Re: c5 x7 fault codes
Aha! So recommended replacement of the particle filter on this engine is 120k miles Kenny.
So a deep clean (but be wary of the internals as the ceramics can crack if cleaning) may be a solution, then you will have to tell it that it has been replaced and again reset the additive counter after.

Re: c5 x7 fault codes
Well spoke to 3 companies who have the equipment to clean the dpf but they were not willing to just clean dpf without a checking for the faults and sorting the faults first.
2 did not give a price saying it would depend on the faults but on quoted £200 minimum.
So I replaced the cat/dpf which cost £410 and I'm going to reset the counter for fluid.
Where is the replacement exhaust 'button' hidden ?

Re: c5 x7 fault codes
Yes, you will need to go into the engine ECU, then repair menu and there should be a section in there for the particle filter - and again somewhere to tell it you have replaced it. Must do that so it can zero out the soot loading back to 0 Gms.
I also note that there was an engine ECU software update Kenny from RPO 13512. Your RPO is 12296. So at some point when the wallet has recovered, it might be worth swinging by the dealer and asking them to update the engine ECU software as you have had the DPF replaced.
You can check your software in the engine ECU - there should be a section giving you the current version - the table below is the updated version:
