Ok just for the record some kind soul put the error codes up on this forum. If Bert had been around he would have pointed you to:
viewtopic.php?f=5&t=19051&p=226355&hilit=error+codes#p226355Now assuming the tilt switch is actually Ok but is being reported as being faulty, in conjunction with the fact that your instruments seem
to be playing up (maybe I imagined that), doesn't that seem to point to a problem in the headlight wiring?
Lets just assume that the wiring has an intermittent fault with the tip over switch (as well as other things). What's going to happen - well
for a start the tip over switch will start to turn off the engine. Then it might think "Oh dear, its now Ok, no need to cut, I think I'll turn it on".
Same with instruments.
I'd be looking very closely at the wiring within the headlight. In particular the pins and sockets within the 12 pin connector but also the line
that goes to the Alarm LED (2 wires) which is necessary for instruments to light up and work (2007+).
Another very remote thought is ECU. I've never heard of anyone having a problem but it's possible. Even more possible to have a loose connection.
Edit: You mentioned roll over sensor removed a couple of months back. What do you mean? Totally removed or removed and replaced? If the former what
did you do to get the voltages correct? If was by resistor or some such is this where a problem might be?
