Before. I was hoping to find them worn when i took them apart.

Pads don't tend to cause an ABS fault, if they have a wear sensor on them it will usually have it's own warning lamp on the dash, seperate to the ABS lamp. Does the warning lamp literally say "ABS" or does it look like a brake drum/shoes?

If it is the ABS lamp, you can try cleaning the surface of the ABS sensors, metallic particles can cause a false fault. Also check the toothed target rings, if rusty you can try wire brushing them but the most common problem with rings is that they fracture and come loose.

It could be a faulty sensor, but you'll need Smart Car specific software on a reader to find out for sure.

If it was the Rotor/Reluctor ring, on start up the ABS light would go out. It would only come on when the vehicle was driven. This is because the ABS ECU wouldn't like the signals it was getting from the Rotor/Reluctor ring then assume there was a fault and ping the light up. It would happen like this every time you set of. This is also assuming it is an analogue ABS system. A digital system has the pick up built into the wheel bearing, this is known as a "Hall effect" system. As geared has said it is more likely to be a sensor itself and there is four of them. Could also be a faulty wire/connector, and worst case scenario the ABS modulator itself. First things to check though would be fuses and earths.

Thanks all for sharing your knowledge. I have repaired both front ABS sensor cables last year, when ABS light came on. Maybe I'll just change those two (£33 each) and see if it makes any difference. I'll also give everything a good clean whilst I'm at it. If that doesn't work I'm going to need proper diags.

Thanks to everyone for attempting to help here, especially the 2 members who got their heads together to get a diagnostic reading for me 😉 (you know who you are)

Front passenger side ABS sensor it was, as diagnosed. Cost me £33 from Eurocarparts. Bit of a pig to change due to access. 

I haven't drove the car yet but I have started it and the lights went out almost immediately.

Puegeot 307 2006, firing but not starting

 

Hi,

The car was sorted last time, it was a broken immobiliser key(tx SF'ers), it then ran ok for a while, but today tried to start the car and it just won't start: if fires up, and that is it, the immobiliser key is fine, the battery seems ok, charging another one,

Will it push and bump start ok? 

 

If so its the starter. Even if it sounds like its turning over healthily.

Highly likely this is the coil pack, that's assuming it is cranking. Then start looking at fuel delivery ie pump and circuit opening relay etc. If it is a coil pack issue, I would strongly recommend you replace the spark plugs too. Worn spark plugs over work the coil packs due to the increased gap, seen loads of destroyed coil pack due to this.

 

This is also assuming it is a petrol.

 

Get it code read first though. :)

Ticking at idle is usually the injectors, some cars are noisier than  others. If it is the injectors, this is normal. Another thing it could be is the tappets, not sure if they are hydraulic on the i20, they were on earlier models like the Getz i believe.

If they are hydraulic, a good oil and filter change usually sorts this after a good run.

Citroen C1 engine fault.

 

It's a Mk 1 at 57k miles. Other night I filled up at a garage in S5, I had let the fuel run a bit low and was about 10 miles into the reserve.

 

A mile later the engine began to misfire and hold back when accelerating, it would run even at light throttle but when depressed the revs took time to catch up with the throttle opening, worse on the hills.

 

Pulled into a car park and in neutral the engine could be revved freely once it caught up with the throttle opening, and it would tick over as normal.

 

Managed to nurse it to my destination and parked up, ticking over ok. Next day the engine eventually started but ran lumpily so I switched off. Smell of petrol from exhaust. The management light did not show at any time.

The AA man said no faults were showing on his diagnostics, crank sensor read ok, and was inconclusive about the fault. Possible coil pack (3)

 

The symptoms (on older cars) were classic fuel starvation/blocked fuel filter. Any suggestions please?

Nope, even on a older car that was not fuel starvation.

If the exhaust stinks of fuel it's simply not burning it, indicating an ignition problem not fuel delivery.

 

Change the spark plugs, coil pack(s) and ignition leads (if it has them)
