And the saga continues...

Trying to get some trust back into my car. So far the 50+ year old classic has fewer issues.

2009 Mini Cooper S (r56) 117,000ish miles Sunroof 6-speed

Background: Just got the dash put back together after sending the CAS, ECU, and Key fob out to get checked out. No issues where found with CAS (My scan tool agrees).

Yesterday: Got the dash put back together. Including some hose clamps on the sunroof drains. Tested both sides and water drains to the outside (just behind the front tiers).

Started it up and checked codes:

• A87E - Ultrasonic sensor, line fault
• A6CB Relay, wiper stage 2, for front wiper
• 9E2F PT-CAN wake-up line - plausibility error
• A8AF FRM Brake light right, faulty
• A8AE FRM Brake light left, faulty
• E72C No message(position EFH driver's door)

The brake lights do actually work, I'm guessing the A87E line fault is a broken wire in that circuit.

The biggest issue I have is that every time I move the right multifunction lever / switch (windshield wipers) my car alarm goes sounds. I don't understand what the two have in common.

TL:DR Car alarm sounds with the use of windshield wipers (and randomly sitting unlocked in driveway).
How should I troubleshoot this?

Thank you for your help.

 

Did you send off your footwell module to be checked? Most of the functions that you have faults for are a FRM function.
