BMW Software Update - ECU Locked - Tuners Beware!

So, I just went in for a software update and as a result, tuning through the OBD is now locked. My tuner managed to do a Bench Flash by removing the ECU, so I'm all good!

This is just warning for all you out there who run a remap, it looks like any new update may lock out remapping through the OBD. This was only an issue for M Performance vehicles for a while but now it looks like the new updates are affecting everyone.

P.S+ Here are some sound clips of the new revised exhaust. Stage 2 + Decat downpipe + added a secondary box in the middle along with a smaller backbox.

Yup I got locked out as well. Iím driving an hour tomorrow morning to have my ECU unlocked at a tuning shop. Iím not even under warranty any longer, so thatís really annoying.

Update: the shop (Alex at Performance Eurowerks in Buffalo Grove, IL was awesome) was able to unlock my ECU. I read my ECU and sent the files to Evolve, still unflashable via OBD, it seems another restriction is the cable used by many tuners. So luckily Alex was able to bench flash my stage 2 file back on the X1.

Cold start deleted and kept my O2 sensors enabled for when emissions comes around (big daddies garage mini cat cel adaptor)

Overall really happy with the service and timing of it all. Had it not been for the hiccup I wouldíve been in and out in less than an hour. It was definitely worth the 60 mile drive each way.

Yeah, I was surprised by this update. Got the update and went directly to the tuner and as he uploaded the file, it failed! Those pins are the ECU are so small too, never gonna update again.
