Yesterday our Roomster started beeping and flashing the warning light about the ABS.

My first thought was to replace the ABS sensors – they are around £7 each and seem to be easy enough to replace by removing the rear wheels. I could also give the connections a bit of a clean at the same time.

What are my chances chances of fixing the issue within 45 minutes of DIY work? I don’t have any diagnostic tools, but if this is a common fault with an easy fix it would be great to know what other peoples experiences.

There are two more sensors at the front wheels, which worsens your odds of a quick fix by blind replacement.

Interesting. So I’m now contemplating buying OBDeleven. I’ve only just found it but people on Reddit seem to like it. It costs €120 and I’m imagining that the mechanic will charge at least that.

Is there potentially anything about this repair that will necessitate taking to a mechanic in the end?

Check some fuses (on battery-top fuseholder) before you go a step further.

Strip fuse No.4 would be my favourite for having a crack in the middle of it, that might barely be visible until unbolted.

Blade fuses 7 and 10 should also be checked

So I was very impressed to see the exact fuse slightly proud (~3mm) of the others when I looked on top of the battery. I pushed it back in but the error still remains.

So my question now is if I pull out this fuse and the others to inspect or check will it create other errors in the process?

Shouldn't add any errors as long as ignition is off when removing fuses.

Thanks Pete.

I pulled each fuse out and tested it with the multimeter for continuity. They all passed.

All fuses back in their slots and the warning light is still on.

What would you try next?
