Multiplexed additive pump DS5

[DinuIoan]

Hi guys,

A friend of mine has a Citroen DS5 2015 2.0 hdi. We put a lexia on his car and it showed up an error U0118 87 which means that is a communication error with the multiplexed additive pump. What do you think? It’s a communication error or it can be the pump?

Thanks.
Ioan.

I had that error message on our 2015 308 Blue HDi. I had to change the Adblue tank.

But he doesn’t have the P1435 00 code. Maybe is just a communication error

Do you know if the P1435 00 comes after the U0118 87? I mean, when the car is trying to use the adblue sistem

Interesting as that is referring to the Eolys additive tank for the DPF.
What is wrong with the car? warning light on?

Yes, he has the engine light on. We think maybe the can bus is frozen, because is freezing outside, like -5 -10 celsius

Not sure what the freeze point of electricity is
