Good morning I have in the workshop a Peugeot 208 1.6 HDi, engine code BHW and registration FD601AK, year 2016.

It has the following error codes:

P1435-00 multiplex additive pump can network error or pump error _present

P0460-00fuel level sensor, signal invalid-present

U1218-81 bsi-present communication fault

P2A00-00 NOx sensor dosage failure measured-intermittent

I should point out that the car does not go into recovery, the engine and service lights come on while driving and go out after about 30 seconds, only to come on again after another 30 seconds.

The engine light that comes on is the one with the exclamation mark inside, different from the one that comes on during the start-up check.

Do you have any information on this?

Thank you
