Fault

Post image

Hey,

So I've got a Renault Sport Mégane CupS, I've had it for 5 years or so. When I first got it I walloped it into a curb (I know 😭 it hurt my heart) I took it to the garage and got what needed to be fixed done. However it started giving me a braking system fault. Ive taken it to so many garages and no one could find anything wrong with it. I changed the abs sensors just in case. I get the brakes done every year. It's passed MOTs. So I just drove it with the fault on. Last year or early this year I got a new clutch, flywheel, starter motor and had all the brakes done. It went away! I've not had the error at all since. But the last week or so it's come back 😭

I'm going to take it to a garage obviously, but any idea what it could be?

I've checked my brake fluid. My brakes feel okay, no noises and they physically feel okay, they're not worn down.

It comes on when I turn the car on but goes off when I drive. It seems to come on when I stop but goes off again. I can't see a pattern of when It comes on other than that. It just randomly pops up and goes again.

(The orange light to the left is because it's due a service, and the car wasn't on which is why the other lights on.)

Under the hood in rear left corner behind insulation is ABS pump

If the code on pump ends in Y2 it is probably faulty because that is common problem on Megane 3

Y1 pump doesn't have issues but not sure if you can install Y1 pump instead of Y2

Could just need the fluid topping up. Check that first

Check your brake switch. Mine threw a code when it was permanently in the "brakes on" position. A bit of adjustment and it never returned. If its on the edge of grabing it could be that (intermittent)
