d241 error SDAR antenna

2012 W221 Bang and Olafsen
My sirius XM satelite quit working and their tech support could not cure.
DAS shows this code: "D241 The antenna cable from the component N87/5 (SDAR control unit) to component A2/82 (SDAR antenna) has an open circuit."
Has anyone else had this and fixed it?
WIS says tear the trunk inside panels out and replace N87/5, hoping there is an easier solution.
Thanking you in advance!

not unheard of for the Sat receiver (tuner) to die - check ebay - license fun ensures
you could try a cheap aftermarket antenna as germany have no clue how to make these work even when new
tuner sits in the left rear wing near the tail light - trim remove is OK... once you have battled the ridiculously mounted plastic trim panel across the back of the car - all the clips will break and its mounted more securely than the from crash structure of most new cars

Measure the resistance of the SDAR antenna wires in the boot behind the left panel.
If it's coaxial, it should be 50 to 100 Ohm.
Otherwise it should be "low".

Thank you for the advice. Reviewing those Wis Instructions. I hate trunk work, bending awkwardly and busted fasteners, Could live without it... we'll see.

the only hell is the bit across the boot catch - it comes off but they all break - very easy to replace (as if they designed it like that !!!!!) and these days most after-market shops stock better ones as they are utter crap from the factory - no doubt REAL Chinese tat using a less UV sensitive and more flexible plastic that's 10 times better than the designed to snap German crap plastic they peddle

four or so out there under $60 - make sure you have return policy as they DIE
