Rear differential error

[adawine]

If you’re on RSR EDC Cancellers, make sure the rears are on the correct side. The pictures in the instructions are kind of disorienting. Switched them to their correct side and never had this error again.

Unfortunately, it didn’t. We did try. But… when my windshield got replace, the installer had the Toyota techstream software and reset it for me. It’s never been back since.

So update; I don’t know what I did other than the car must’ve decided it would be accepting of the new suspension parts and alignment… all I did was raise the car back up, check all the plugs/sensors to include the differential wires/plug, the ride height/headlight level sensors and the electronic damper plugs, then I unplugged the negative on the battery, let it sit for three days, charged it up, plugged it back in, immediately flashed both the engine tune and trans tune and went for a drive of about 100 more miles. When I went to start it up the morning of last weekends track events; NO CODES at all and the car ran great… I don’t really think anything I did above really did it… chalk it up to the bmw in it just needing some miles to “relearn”?!? I'll take it either way…

here's something else that can trigger the warning.. your Ground connections.

Recently I had my car towed into the Dealership as the car was cranking, but there was no ignition.
The Tech came to find that the bolt responsible for grounding the fuel pump had worked its way loose. I had removed the bolt to install Dynamat LAST YEAR (and re-tightened), and it just came loose now. I was also having the Diff Error come up intermittently over the past couple of weeks, which is now gone as well.

Yea that happens sometimes. An earth strap bolt you have removed and tightened totally correctly just mysteriously comes loose. Happens all the time

It’s a bolt with a nylon insert, apparently. I’ll be taking a better look at it tomorrow.

Regardless, it still took over a year for the ground to come loose

I keep getting this but only when it sits for a few days. I think mine is related to possible low voltage.
