E-diff issue - please help!

I recently purchased a 2014 F12 with 22k miles. I have developed a random but somewhat frequent problem with the e-diff where it lock up during sharp low speed parking lot turns. It acts like an old 4x4 when driven on pavement in 4WD low. I get no codes when this happens, but if I turn it off it will turn back on in limp mode with an e-diff and manetino failure. If I let it sit for 30 minutes it fixes itself and drives like normal. .

I do not have a local dealership and my local shop does not have a Leonardo. My shop used their universal scanner and recorded the following errors…

App electronic differential pressure drift invalid signal (electronic differential pressure sensor drift)

Electronic differential pressure too low

I spoke with a specialist who assured me it is probably not an internal mechanical failure. He said it could be a relay, manetino module, or e-diff pump.

I’d like to start with the relay, but can’t find any relay that seems to control the e-diff.

Would love to hear from anyone who has had an experience like this. Any input would be appreciated.
