Yes a bag leaking.
Common problem but not a bad job to change.

As said above.
You need the module to plug it into.
It cuts the reverse sensors and that kind of thing when you plug a trailer in.
Also stops errors for bulbs cleaver little box.

Has the e53 got a DPF mine didn't. Going to get shot for my next. I have a bmw and a n mb that have dpf's and both of us are retired now so they only do short trips.

Fingers crossed for help.

Could well be a dodgy recon injector.
Personally i won't buy from Euro for the same reason had a few dodgy parts from them.
