P068500 Circuit 87 combustion engine

[K1AN1]

Hi All,

So the woes with my 220cdi continue, I'm currently at a loss as to what this code relates to. A search of the internet doesn't bring much up. Im wondering if this has anything to do with way the car keeps going into limp mode.

Ive replaced boost pipes, that were leaking, DPF sensor and regened, Boost pressure control "A" (under the inlet manifold) although its kicking the error up again.

So now am stumped. Just wondered if anyone has had any experience with the above.

Many thanks

Dont know about all code readers but my star gives some help in diagnosis for a fault code .think u need to find something similar. If yr going into limp mode something must cme up.

Any chance of a picture of the fuse/relays under the bonnet

Sounds like an air leak to me....boost pressure control is usually a loss of boost pressure!

It did indeed have an air leak, a local indi did a leak/smoke test and the only place it was leaking from was the intercooler boost hoses which have been replaced. It's booked in to go next week. Just bugs me when I can't figure something out myself!

Did your internet search have any reference to
"Check ECM power supply relay"
"Check harness to the ECM for any fraying"

Hi Matt,
I have a 2014 250CDi Blue Efficiency sport and had a P068501 fault code with those items listed. So far can't identify the fault
