Puegeot 307 -ABS light

[Oscar]

Thought I would ask the experts !! Got a 03 reg 307, 1.3 petrol with 109 k miles which I bought 8 months ago as a run about and is fine. Last week out the blue ABS light comes on and stays on dash. Every time stop engine it resets itself and randomly comes on within a mile some times or not at all on a 25 mile trip yesterday or any where inbetween. Always resets itself on stopping engine. Anybody know anything about this system and point me to it and a cause ??? [loose connector maybe?] many thanks O

My Astra van does exactly the same, in my case it'll be a wheel sensor more than likely it has been on all the other vauxhalls I've had. Not difficult or even that expensive to change I might even have 1 kicking about but I just can't be arsed tbf !.

Yep more than likely a wheel speed sensor , trouble is you have to get a diagnostic tool on it to find out which one , they don't cost much but its finding which one that costs

need to plug it in

Uneven wheel size on the same axle, but that's unlikely?
I'd disconnect each sensor and look for green corrosion in the connector/s ................
Shake wheel at the top to make sure you haven't wheel bearing trouble?
Take sensor/s out and clean toothed rotor with an air line.
If above fails, local mechanic will plug it in for small money, just ask how much first. This will also narrow the hunt down to one corner.
OBD2 readers on E-Bay for the same price as a read

Thought I would ask the experts !!

Cheeky pup ...............

had light come on in the van a while back and was brake pad sensor wiring. wire broken about 1ft up the loom cause it took me till the last corner ripping all the wiring out the looms till I found it

Cant remember if it was the ABS light that came on or the Handbrake light now?

Start simple. Are the brake pads worn?

After that sensors.

Check each sensor, they are bolted on with a single bolt, rust builds up between the sensor and the hub it's bolted to, the rust pushes the sensor away, it's plastic and flexes, resulting in the sensor not being close enough to the sensor ring. Remove them, clean the mounting face and refit, a bit of copper grease when refitting on the mounting face helps to hold back further corrosion. It will only cost a bit of time.
Done several on those in the past, never needed a new sensor, despite the code reader saying they were faulty, it registers a fault because it can't 'see' the wheel, but it not necessarily the sensor itself, but I did have the code reader to point me to the sensor giving trouble, but no reason you couldn't have a look at each one and eliminate them.

Don't waste your time checking or changing wheel sensors, it may not be the problem. I've just changed an abs pump and ecu module on an 02 bmw after we had the same warning light on the dash. Get someone to diagnose the fault and then decide how you want to sort it. I bought a complete used pump and ecu from a breakers yard for £40 and fitted it myself. Needed recoding so the chassis numbers matched up again but I already had cheap diagnostic equipment which was able to do it. None of it was difficult and there are plenty of guides on YouTube if you're not sure where to start.
