09 S4 B8 Stage 1.. i bought it recently at a good price but have a problem...
the gear changes are smooth at relaxed driving...
but under a heavy right foot there are half second flat spots when changing up through the gears...
mechatronic repair was fitted in Nov 2018 when the car was at 90k
cars now at 1o6k
any ideas on why the sluggishness?
Does the gearbox need a tune?
Is the mech unit failing again?
Many Thanks in advance
;-)
