Could it be that the pump is changed and the reset process is done that I need to fill the car up 10L or more and just give it a drive? Or since you said that it is not the correct pump then nothing will make it work? Also on the new pumps packaging there was a sticker that said : adaption with diagbox is necessary however the ECU workshop that I went didn't have the diagbox setup specifically. Maybe it is worth give it a shot with diagbox?GiveMeABreak wrote: ↑28 Oct 2023, 21:39 Ok, so here is the fault descriptor for P1494 96:
As far as regeneration goes, essentially there won't be any additive mixed with the fuel in the tank, so it means that assisted regeneration won't be possible and the particle filter will have to rely on passive regeneration which only happens at 550 °C (so on a long motorway journey where the exhaust gasses reach this temperature). So be wary that the filter doesn't start to block as anything over 70% full can result in regeneration being ineffective and the filter will need removing for cleaning in this case.
Fault Code: P1434 96 Description of Fault: Multiplexed additive pump: Multiplexed pump fault. Particle filter additive system: Electrical failure.
Detection of at least 6 faulty items of information sent by the multiplexed additive pump.
The time of appearance of the fault code is 6 seconds.Conditions for Fault to clear: The following conditions have to be met:
- Addition of 10 litres of fuel
- Driving with the engine hot for 5 minutesDowngrade Modes whilst Fault is active: - Symptoms:
- Lack of power
- Absence of automatic stopping of the internal combustion engine
- Starting problem
- Deactivation or switching off of the cruise control/speed limiter function
- Fluid leak/smells (diesel fuel, oil, etc.)
Suspect Areas:
- Electrical harness
Connector- Additive level

- Additive injector
- Multiplexed additive pump
- Fuel pump - gauge module
As for official part numbers, we can help if you need an original, genuine part number or part diagram, and can't already find the info you need on the Forum. For this service, we do ask for a membership upgrade for official parts data as we are in turn charged for this. It will cover you for future part number requests for up to 2 years, so excellent value.
If interested, links are below, then provide your vehicle's VIN in full, which will be masked automatically when you submit your post.

Also was thinking about maybe filling up the old pump and give it a try.
