We have cleaned the breaks etc with break cleaner as well as refurbishing the hubs themeselves and giving the struts a good clean up.

We had not got round to the rears as we ran into more bad weather.

Yipeeeee - one of my sons was home this weekend (he works on race and drift cars in the week so only gets home some weekends) and tested all of the sensors.

It could be a bad connection where a sensor plugs in, but carefully check ALL the pads.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all - I was wondering if anyone can help?
I have a 2005 Carrera 2 and the dash break pad light came on this morning. I have checked the pads and they look good.
Is there a possible malfunction on the sensor and can it be re set?
Cheers
Steve
Steve!
The wear sensors are on a loop circuit that goes from wheel to wheel, and to the instrument cluster. If there is a break in the loop, or it goes to ground (by a worn sensor) then the light comes on.
It could be a bad connection where a sensor plugs in, but carefully check ALL the pads. Don't assume that because the outer pads are OK then the inner ones will be the same.
Once you sort out the problem, the light should go off by itself.
Hi Richard - many thanks for your swift reply - it's obvious that you are the man!
This afternoon the light went off for 30 mins and then decided to come on again after I had been parked for a while!
I will have a good look at the weekend re the inside shoes just to make sure.
How long can I drive if the sensore is not faulty - the light has only just started to come on over the past week?
Many thanks
Steve
The sensors are about 5mm diameter, so as long as the pads are wearing evenly (ie not tapered) then you should be OK for a while.
Was it wet when the light came on? Maybe water in the connector on one of the sensors?
Hi Richard - many thanks - yes I was starting to come to the same conclusion as the light does come on as and when!
I was looking to do it today - then the weather really got horrible.
I will have a look at the weekend.
By the way your C2 looks very nice indeed.
Cheers
Steve
Hi Guys - well my son and I have had all wheels off and inspected the pads - they are all fine, in fact they really look nearly new to be honest with plenty on both sides all round!
We did find a sensor conector zip tied on the front offside and placed it back in - the sensor warning light came on straight away so we disconected it and re zip tied it!
We have cleaned the breaks etc with break cleaner as well as refurbishing the hubs themeselves and giving the struts a good clean up. It all lookes good but the light still comes on as and when!!
Is there anything else we can try or is it a trip to a service centre for a diagnostic?
Cheers and a happy easter to you all.
Steve
I don't think a diagnostic check would tell you which sensor was causing the problem. If it was me I would change all four. They are about £35 a set from somewhere like Euro Car Parts.
Hi Guys - well the saga continues - we took both front sensors off and the light came on all of the time - so we put them back after a good clean and the light is still on! We had not got round to the rears as we ran into more bad weather.
I have been on to the Euro Parts site and they have them in stock. The only problem is that they only have the Eicher for the front and Sebro for the rear, is it ok to mix.? Luckily I have a branch ten minutes away from my home.
By the way I live in North Staffs so I would either go to a Manchester OPC or a specialist which is much closer called JMH - they have a good web site and the prices look to be half the OPC prices.
Anyway thanks for your support and advice it's been a great help to a novice.
Cheers
Steve
It would be fine to mix-and-match. They work in exactly the same way, no matter what make. A genuine set from an OPC are a shade under £60 inc VAT, and they list the same part number for front and rear.
Like I said, the circuit is a loop from wheel to wheel, so if you disconnect any one the light comes on. Also, if there is a short to ground on any sensor the light will also come on. So you would need one sensor, and swap it from wheel to wheel until the light goes out. Unless you have two dodgy sensors, of course....
Like I said, if there is a short to ground, or break in the circuit, anywhere in the loop, it would cause the light to come on. I'm not sure a diagnostic check would tell you exactly where the fault is, but it would be worth a try.
The only way I can think of to eliminate the sensors is to unplug all the sensors and put a loop wire in place of each to see if the light goes out. If it doesn't, then you must have a problem in the wiring loom somewhere.
Yipeeeee - one of my sons was home this weekend (he works on race and drift cars in the week so only gets home some weekends) and tested all of the sensors. Guess what it was one of the new ones that was faulty!!!!
Anyway it's now sorted - many thanks for your help.
Regards
Steve
