ABS light coming on when tank half empty

[stuart bowes]

I don't pretend to be aware of how it all works but it does occur to me that the fuel gauge is part of the DIM which is known to be problematic

But then the failure symptoms are perhaps controlled by or at least passed though the CEM which is also a known weak point

I would probably start by emailing Tilbury volvo diagnostics and asking them if they think there's any way a relay or dry joint etc could cause these issues. Seeing as an email is free and takes all of 5 minutes

That is unless someone else comes along with a better idea

Is it possible the cause and effects are not actually linked or do you fully trust the info to be logical and throughly tested

There are some under seat connectors which could be more likely, would a yaw sensor for example if fitted affect abs when it fails (?) And obviously the seat heater connector would be in a similar place. But how that would relate to fuel level I don't know. Possibly just all coincidental and nothing to do with it

None of this is based on 1st hand knowledge
