[EB89]

Ive had this issue twice,

For me it appears for around 1 week, and then went away for 6 months, then came back for a week and then went away and its been almost 8 months now.

I get those same codes

2EOF - Valvetronic System deactivated adj fault to frequent
2DDO - Valvetronic System control deviation warning threshold exceeded

And another that says "valvetronic disabled, adjustment fault to frequent"

When its playing up i have weird sounding down shifts and longer drawn out exhaust noise, instead of a sharp grunt when downshifting its extended.

Then just goes away by itself.
