Disco 2 TD5 brake warning light on

benh999 · Oct 1, 2021

Now I assume this will be related however I need To ask the question. I’ve had my drive shaft oil seal replaced today. Picked up the truck this evening and the handbrake warning light is constantly on. On the start up the light also stays on(doesn’t come on then off then on again if that makes sense)
I assume this has something to do with today’s job as I’ve checked fluid level and the handbrake sensor..

Any suggestions please clever people?

All three brake lights are working?

Are the "3 amigos" coming on then off after ignition? If yes, make sure that the fluid reservoir's plug is well connected, eventually unplug it and bridge the pins to rule out the level sensor, if the 3 amigos are not working it's possible that they should be on and there is a fault logged in the system probaby on that ABS sensor's circuit where you changed the seal, check the connection.

So the three amigos have always had a
Mind of their own. Sometimes they go out, sometimes they stay on.

when they do stay illuminated, the ABS light is always the one that stays on before the other two light up again.

since I’ve had the oil seal repaired they stay on and as before the ABS light stays on however now the Brake warning light is on.
I drove it to the garage fine however from the moment I collected her the brake light is constantly on.

You should have said from the beginning the 3 amigos thing... the read brake/hanbrake light is part of the fault protocol together with the 3 amigos, it should be on all the time but in reality it comes on with 3 amigos when the fault is a permannent short or open circuit.
The so called "brake" in the table(which is for handbrake or fluid level too) is on too now on your's... the simplest way to find the fault is to read the code
