SDARS antenna open circuit and TPMS error
I'm having some weird issues with my satellite radio and I'm wondering if anyone has any advice.
For about the last year it's been intermittely cutting out, I usually lose reception for about 10 or 15 seconds every 5 to 10 minutes. And sometimes it will play normally but either won't list the channels or I won't be able to change the channel. I have an A536 code for SDARS: Satellite aerial circuit open.
I checked the trunk for any obvious wiring damage and I don't see anything, also cleaned the connection for the antenna on the satellite module. It's a used satellite module that I installed a couple years ago (I had the satellite prep but it didn't have it installed before). It worked fine for the couple years until it started doing this. It mostly seems to play normally until it cuts out, then it's fine again when it comes back on.
I've tried the Siruis refresh signal a couple times and it hasn't helped - the open circuit code seems to indicate the circuit is intermittently dropping out but I'm not sure where to look since I don't see any wiring damage, at least in the obvious areas.
I also recently got codes 604E RDC System and 6056 Wheel electronics, rear left. I'm not sure if the TPMS sensor is just dying (I believe it's original from '08) or if might be a problem with the wiring for the rear left transmitter, possibly on the same harness as the antenna? I'm planning to swap the rear left and rear right wheels to see if the code moves along with the sensor.
Any other ideas on where I should look next? It's a 2008 528i
