C4GP B78 active cruise

Hi all new to the forum

First of all can you edit or confirm the year - this model was not produced in 2004 if that's what you mean by 54 from your first sentence. A VIN will be better though as I can see exactly what you do have and what equipment.

Replacing the brake switch was unnecessary on the face of it, as most faults relating to speed / engine will result in the a lot of functions being deactivated like cruise control whilst the fault is active. Of course, clearing the faults won't do anything until the underlying cause is fixed. Many generic code readers can't access the extended / constructor-specific codes on modern vehicles, so there may still be codes presenting that you cannot detect.

Once I have your VIN I can look at the codes you have listed as they relate to your vehicle.

Thank you for replying and offering some help! Yes apologies it’s a 2016 (now edited).

Yes I agreed on the brake switch but I thought it could be sensing an occasional rouge signal bd besides it’s was a cheap part to change.
I will PM you the vin again if that’s ok

Thanks again

Please put your VIN here, only staff can see it as it is automatically masked from public view on submission by our software.

Ok, so after checking your VIN, there would appear to be an outstanding after-sales campaign that must be carried out on this vehicle. Therefore I suggest before you do anything else that you contact your local Citroen Dealer and quote your VIN.

I can't tell you what it specifically relates to, but I had another member yesterday who had a recall he was unaware of and when he called the dealer they booked him in for a complete timing belt job urgently, and they picked up the entire bill at over £500.

It may be totally unrelated, but I know that some of the codes you have listed are included in a Technical Service Bulletin, so there is likely a known issue. Might be worth letting them know those codes at the same time.

Sometimes the dealer network loose contacts of vehicle owners once the vehicles change hands on the second hand market and new owners don't use the main dealers for servicing. I doubt it is an urgent safety recall as this would be a VOSA recall I suspect, but may still be important.

Hi Marc
Yes there is a recall outstanding-engine electronic cooling management. This is to adjust the ecu parameters to stop any overheating issues. Due to family Issues towards the end of last year and now covid I never did make the dealears for the recall. Problem is now they will not carry out a recall in the situation the car is known in.
If you have access to the technical service bulletins, could you please share the one relating to the dtc’s that I have. If it’s a paid for access I would be happy to pay

Again thank you for your help
