My 330e touring is produced in July, meaning model year 2021 (suppose all 330e touring are). Have the 20A engine.

Hello,

I have a model year 2021 G20 330e Xdrive and it seems that BMW/Bosch has locked the back door for ECU tuning. Two local tuning company stated this info to me in this week. Any idea how or who might have a solution for this issue?

ps. my motor type is B48B20A

hybrid motor adds weight and from what i've seen, despite the power increases the net effect of adding a hybrid motor doesn't really impact 1/4 mile, but may be faster due to additional torque off the line.

Ask the tuner, i think VipinLJ mentioned bm3 asked him to send something / come in for an unlock?

The DME in my car needs to be bench unlocked and I found out about all this much before there was info regarding BMW increasing the security on the new DMEs (back in December). No one knew why it happened then because everyone thought only the new M2C and F80 M3/4 had the security lock, not a measly 330i!! We found out after my car was bricked that that was the issue.
I haven't been in touch with PTF personally after that incident because I'm wary of shippingy DME and worried about the shipping company losing it. But I know of others who have shipped their DMEs to get it bench unlocked and have been able to flash their car. If there was a brick and mortar place near where I live that could do it, I would've taken the chance!
