I have noticed a couple of times, that the idle sits too high - just over 1100RPM, I have checked the diagnostics and it records a 3-1-1 fault codes which appears to be speedometer signal missing so wonder if this is connected? I have a copy of the LH 2.4 for the B230F engine on a 240 and this refers to a blue wire to pin 34 is this the same on the 2.4 fitted to the 740? The only thing I have done recently is remove the dashboard to fit new panel lamps, I can find a blue wire and removed and refitted the plug to see if this cures it but is this the wire the manual refers to. Thanks in advance.
