Discovery 2, 3 amigos

Afternoon.
This morning I bypassed the shuttle valve in the hope of removing the 3 amigos. It hasn't worked.
What else should I be doing to resolve this issue. MOT on Friday.
Thanks Andy

Hi. The only straight way to fix this is to read te fault code cos even if it's a simple thing like a sensor you can't just guess which one so as you wasnt lucky enough to be a SVS related fault you definitely need to plug in a scanner now

+1^ sadly.

There is a test which you can do with multimeter but quite unikely to find something unless one sensor is fubar. You can unplug and measure ABS sensor's resistance, a good one should have between 950 - 1100 Ohm, also check if the two earth points in front of the airbox are OK. That's about all you can do without a proper diagnostic tool

Thank you very much for advice I'll try your suggestions, if it doesn't work i'll will get it scanned.
It is just getting to point of is it worth the hassle of fixing all these age related issues.

You have to regard hubs as being like tyres and brake pads. Consumables, not really anything else, and not enough to condemn a vehicle. The sensor is basically telling you it is time to replace the hub cos the bearing's knacked.

ok thank you I will get a diagnostic scanner onto it asap
