MHD valvetronic system: warning threshold value, feedback control deviation exceeded

moegd55 · 04-04-2021, 08:48 PM

For fun i decided to scan for error codes and I got Error 135704 (valvetronic system: warning threshold value, feedback control deviation exceeded).

Car still running strong and smooth.

Anyone experienced this before? Thx for your help.

Im just experiencing this now.. but sometimes theres an unusual rough idling when engine is running on a traffic light.

Would appreciate any info from your experience.
