Wiring Harness wear causing Check Engine light (2010 Clubman)

Hi all- just an FYI:
Interesting fault with my 2010 Clubman that I thought I'd share (apologies if I missed this reported in a different thread, I looked but didn't see one).

I had a check engine light come on so I brought it to a local shop that has Mini experience (car is under warranty, but I'm 230+ miles to closest dealership- didn't want to send car if it was something really simple/cheap).

The pulled the codes: 2728 Solenoid Valve; 272C pump motor; 272A Solenoid Valve; 272E pump motor; 271B Heater; 2719 Heater
They reset them and they instantly came back.

After checking their subscription access to MINI data, they discovered that that combination of codes has been found at other shops and was related to harness wear allowing wires to corrode.

Specifically they found that the wiring was corroded and broken at a place where it was rubbing against the rear swing arm.

Seems like a bad wire routing plan that is just now raising its head to cause problems.

Although there are no noticeable drive issues, I'm going to see if I can get Roadside assistance to transport the car to the dealer and then bring it back (posting in another thread about best way to use the roadside assistance).

Specifically where was this on the vehicle?
Appreciate the insight; looking for additional follow-up. Thanks!

Sorry, Erik-
That's actually as specific as I have from the local garage. "wiring harness rubbing on the rear swing arm"

I'll ask for more details from the Mini service center once I get it there and I'll post a followup.

Erik- (and anyone else who is interested)
Just got the car back from the Mini service place and got more detail on where/what the fault was-- The wiring that was broken was leading to the DMTL (Diagnostic Module Tank Leakage) Pump -- 3 wires were damaged by chafing against the lower control arm for the right rear wheel.

I just picked up my mini from the dealer for the timing chain campaign. they pulled all the fault codes and cleared them.. this one came back when they started the car to pull it around for me. the tech said he didnt see anything apparent when he was working on the car. i'm wondering if this is a place to start looking.

do you know what they did to fix it?

thanks,
