Hi All.

My Audi 2014 Audi A6 C7 2.0tdi ultra Stronic. Few weeks ago whilst driving Glow plug light come on the dash
along with a orange triangle with explanation mark in the centre.On my display it read GEARBOX MALFUNCTION YOU MAY CONTINUE DRIVING LIMITED FUNCTIONALITY. The car would go into Limp mode and jerk and skip gears only selecting Gears 2,3 and 5 (very confused)
sometimes the problems will disappear 30-40seconds,other times i would have to stop,switch engine off then restart and will have no problems.

I have changed Gearbox oil and filter

Also i have connected to VCDS

:P0736 Transmission input speed sensor (G182)

My mechanic wants me to change the Mechatronic unit,
which is costing north of £2000+VAT
Anyone has similar fault!

Any advice or help from anyone would be great thanks
