Ok here is a good one for you, I have a 2003 beautiful S Type, I can travel anywhere in the UK and sometimes do with no problem, but on a stretch of road that runs past a huge vegetable packing  place my engine management  comes on (not every time) , I have a friend with a P38 Range Rover and it brings his EAS light on, on the very.  the same stretch of road.

hi

no HV pylons near you when it happens, 

some pylons with heavy load can cause large amounts of interference, could be a possibility 

its got to be interference of some kind

cheers

Joe

Come to think of Joe there is, the 88000 volt ones.   , when I tell anyone they think I am crazy.  Cheers. 

Remember that P38s just like to flash their lights to remind you that they are there, and that they'll be draining your wallet soon. Lovely cars, but needy!

The P38 may not have the latest version of the IR receiver and they are easily confused by interference.

Yes I had one of those, never again, driving 40 miles on the bump stops because the suspension decided to lower itself.

Nah, this is clearly a case (or two cases) of demonic possession. You will need to have the car(s) exorcised. If that doesn't work, there is no alternative but to switch off life support and provide a decent burial.

Nah ??   is that some kind of Chinky takeaway.
