trust me mate their is deffo somethin wrong!
why would the VSA come on when nothing is going wrong? 25mph in 3rd going right kills all power etc..
the track rod ends wouldnt cause this notchy feeling its really strange! and didnt happen untill the clutch and dmf where changed...
surely honda would know to check things like tyres etc?
Depending how bad the geometry is if you accelerate in a bend the VSA will kick in.
The triangle flashes for VSA, EBD and ABS as well as traction control
But there may be a problem with the ABS wheel speed sensor that plugs into the hub.
You might want to unbolt, clean it and replace.
Take the wheel and brake disk off if you want to see whats going on with the sensor gear...might be covered in crud.
Tyres, pressures and their condition is your repsonsibility and not hondas.
Unless its service time
You say the steering is notchy... which is unrelated to DMF/Clutch.
Notchy steering is normally rack, or seized track rod end.
CV joints/driveshafts can give a going over bump feel when turning.
Take it to a car park...put it on full lock in both directions and slowly accelerate.
If you hear or feel a rythmically clanging/banging and possibly lurching with wheel rotation then the CV joints are shot.
