Drexler diff upgrade?
My bmw m4 (f82) went into differential limp mode at the track yesterday. I used ISTA+ to diagnose the issue and verified that the wiring harness is not shorted or open. The service procedure says to replace the Differential Servo motor which is $500 new.
Should I bother to throw parts at this or do I spend $3500 on a drexler diff, I hate having electrical failures and this leaves a bad taste in my mouth about the ediff. |

If you plan to ride on a circuit or in the mountains, changing to a Drexler is the best option. Keep in mind that apart from diff you need a left driveshaft and coding.
M2 CSR Drexler diff is a best option. |
