can anyone help me with fault code U1711,it's a manual not a selespeed.it stopping me from revving past 4500 rpm.... :'(
Others may help on this board, but I'd also suggest searching and/or asking on alfaowner.com.
Good luck!
Possibly an odd one. I don't know how to interpret it, but I believe U1711 means:
U1711 CAN Network (NCM - NCA)
Thus, a CANBUS communication network error between the engine management ECU and.....err, automatic gearbox node. :o
Obviously doesn't make sense for your car, so I don't know...
'U' should mean 'communication network' (ie: CANBUS). '7' should mean the transmission. Was any work done on the car? Any chance a plug/loom could be disconnected? Have a look, see if anything seems unplugged around the gearbox.
