Citroen Relay P15BE 72 & Hill Start and ESC unavailable

Unread post by RelayLoser »

Hi, I hope someone can help! I had a CEL appear and got a scan done from a garage, P15BE 72 DPF Spark Plug Relay - Blocked Open

I checked the 25 A fuse which looked ok and tested the relay for the circuit which seemed to work. Put it back together and had no more issues until the other day. Light popped back on and van in limp mode.

When starting the van up I now have ESC and Hill Holder unavailable! I scanned but no other codes present...

I have no wiring diagrams so I'm struggling to diagnose further..

Any advice from you gurus?

Would I be wrong in assuming you have resolved this by now? :)
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Hah, unfortunately Mick you'd be wrong!

I was away in Europe during that and after clearing codes and letting her sit for a while turnee off the fault cleared. Nowadays I've been getting a P0234 turbo/supercharger pressure error which then activates the ESC and Hill Holder unavailable errors accompanied with the limp mode; it apparently just randomly occurs, I've had no luck trying to recreate it. It hasnt happened much recently but I'll maybe try get my hands on the manufacturer scanner and diagbox to do a proper delve. Happy for you to close this if you're doing housekeeping and if I have this same issue I can make a fresher post
