Peugeot Partner fault codes

[Bolln]

Hey

Have a Peugeot Partner 2013 Diesel, 9H06 1560cm3, 66.0kW (90hk)

I have e warning in the display " Engine need repair" and the risk of clogging of praticelfilter.

Fault codes that is active:

P1435
Multiplexed Additive pump. Can Network or pump fault
DTC status:
Permanent

P1434
Multiplexed Additive pump. Pump fault
DTC Status:
Permanent

P1434( yes 2 of the same faultcode)
Multiplexed Additive pump. Pump fault
DTC Status:

P3008
Air Circuit. Air flow higher than recommended
DTC status:
Intermittet

P2562
Fixed Geometry Turbo. Position incorrect in relation to the reference value.
No enough turbocharing
DTC status:
Intermittett

what to do?

Is it possible that my additive levels are low, so i can just refill the tank?

If it was empty you would get a specific dash message, so it's either a fault with the pump, or the wiring to it. These are similar to the Ad blue tanks, in that the pumps only come with the tank, at vast cost - if you can even get one at the moment! Failure rate is much lower than ad blue tanks, so a used part is probably OK.

So it is eolys fluid in this car? I got a tip from a local mechanic that i should try to refill first before i did something Else. I have had de car for 3 years now and never refilled the tank.

Is it now possible to just buy the pump ND replace it?
