BMW F20 after reflash cannot go beyond 30 kph

Post by hubabuba254 »

Hello,

Today I tried to reflash the DME with new maps, I tried two files and I had simmilar problem with both.
Car accelerates nicely, but I cannot go beyond 30 kph (rpms are not limited as it happens on every gear).
After error scan there is 201101, is that relevant for the issue?

Can it be related to the DME program date being 2019? Can I solve it by downgrading DME with E-SYS and copying relevant maps?

Many thanks for assistance as I'm beginner

Wait, copying relevant Maps? Did you flash file from another car?

Not really, I did VR of my ECU and then sent it to the tuner. After that flashed it and had the problem with 30 kph.
I had two separate tunes of the same VR and had the same issue with both.

When i flashed back stock it was normal...

You have modified some data that should not be touched.

Ok guys, problem fixed. Just Virtual Read was from different version most likely, I downgraded DME to earlier I-Step and flashed again. Now problem is gone :D
