2016 Sprinter W906
Hi folks,

I've spent a good few hours trying to find any information I can on 4 error codes that popped up yesterday.

I have a 2016 Sprinter W906. Last few weeks it has had a minor coolant leak that after lots of troubleshooting I've managed to source to the water pump. I've booked it in to have the pump replaced soon but in the meantime the dreaded check engine light came on yesterday.

There's 4 new error codes, ignore anything relating to NOx. Unfortunately my diagnostic tool doesn't offer any insight as to what on earth those might be. I don't have a service manual, I wouldn't mind paying to get one but would appreciate if someone could point me to a reliable source, prices seem to vary wildly from a quick google search and I have no clue what to look for / expect.

All I want is to figure out if this relates to the water pump leak and will be addressed by replacing that or if I'm looking at some other expensive issue. I have a 2,000 mile work trip coming up soon and need to sort this out asap.

Many thanks for any help and pointers.
