So I've had the d4 for 2 years now. Recently I noticed reduced engine performance. This was only for a few seconds so didn't think anything of it.
Yesterday it went into full limp mode 4 times in 30 miles before finally coming up with an engine warning light.
In Vida, the errors were
- Cem-u030141 (software incompatibility)
ECM-00be00
ECM-p241300 (egr performance)
ECM-226200 (low boost)
I wiped the codes this morning and gave it a drive l, everything seemed fine until I almost got home, switched down to second to turn a corner and it went into limp mode again
Checked the codes, same codes
I left it until I finished work, went to start the car. It started but only idled for maybe 5 seconds then you could hear it lose revs and stall.
When I checked the codes again, the only change in codes was the CEM-U030141 error.
Could the software be cause all of these issues?
