Had the Disco MOTd and serviced Wednesday, took it on a 250 mile motorway journey Friday and yesterday the bloody EMS Fault light lit up and won't clear.
The handbook states; "Avoid high speeds and consult your authorised dealer as soon as possible"
I've tried searching threads here and not found much of use. Does anyone know if there is a quick reboot I can try? Would disconnecting the battery for 10 seconds help?

Bill at Autoland plugged his diagnostic kit in and it told him there was an EGR fault. It has been reset but if it returns I'm looking at an EGR Valve replacement.
