OM651 P0101(29) & P0102(00)

[Lugy]

Hi folks, I'm trying to trace a fault with my 2013 313 Sprinter. It dropped in to limp mode a couple of weeks ago and threw a flashing EML.
The codes were P0101(29) and P0102(00), along with P2BAC (which I believe isn't a fault as such).
I've tried another MAF sensor with no luck and also had the EGR out to check it was clear.
I'm going to check the wiring today but beyond that I'm a bit stuck.
From what I've read, it's not an uncommon issue but it seems the solution isn't!
Any pointers from anyone?

Cheers!

Yes, that certainly does! Even more so that I've re-read it properly where it mentions it being the lambda adaptions that need reset. That could be a good place to start!

I *may* have solved this issue, I've reset the lambda sensors as per Tony's link above, currently there's no fault.
Fingers crossed it stays that way!

How do you reset these sensors? I don’t have a xentry
