Hi all, I have been working on my neighbour's Q7 for 4 weeks now now trying to sort out a P102A00 Torque Restriction due to coolant temperature fault and I'm at my wits end with it. Has someone else come across this fault before and got it rectified, if so, how? I have replaced water pump, coolant regulator valve, G83 x 2 temperature sensors, checked resistance & voltage at sensors & ECU, rewired corroded connector plugs and still can't get it sorted...PLEASE HELP. With engine idling it doesn't throw up fault but it does the minute you start to drive it.
