(phone on a mount on side window, sorry for vibrations)
1.9PD 130 AVF tiptronic with 226K miles on it.
Around 1700rpm the car seems unable to maintain steady revs, dipping / surging by around 250 rpm on a quite regular cycle.
It was in cruise control with the gearbox in manual mode, 5th gear. 4th also does it, and I think 3rd. Checked cruise mode to be sure there is no issue with the pedal.
Disconnect MAF doesn't make a difference (other than car no longer pulls properly)
No fault codes in VCDS
VCDS timing appears ok (-0.6-0 degrees).
Ideas anyone, or further investigations that make sense with VCDS?
Thanks!
