This happened right after the flex part of the exhaustpipe broke. Exhaust pipe repaired.
Wire harness from transmission and other wires in the are do not have any signs of damage or overheating.
This is a USA sprinter, not sure how I end up in UK??

Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
I am here Sundays through Thursdays from around 5 am to 2 pm Mountain time.If you respond and I do not respond back right away I will do so as soon as I can.

If you clear out all of the codes do any of them come back right away or soon after running the vehicle?

Let me know,thanks Pete

Those are all the codes that come back. Sprinter is in permanent limp mode= 2nd gear.
ESP and low oil light on dashboard, but oil level is good.
Are you familiar with Sprinter can bus?

The exhaust pipe broke at the downpipe after the catalityc converter at the flex join.....it may be related or just bad luck coincidence.
I have an Icarsoft MBII with me to give you any data you want

O.k., some of the codes are not coming up for me here on this.I wanted to see if only some came back that I could help narrow down the fault with.

Unfortunately, this is all of the info I have on this myself here.Others here may be able to help further on this with the information you need.I will opt out and open your question up to everyone else here to see if they can help with this.I hope you can get this resolved with ease.

Thanks, Pete
