It the speedo sensor. On the back of the gearbox
Re: Electrical problem - ben87 - 17-03-2012
is that the white plug you can access from beneath the battery tray?
Electrical problem - Matt - 17-03-2012
I believe so. Tbh I didnt replace mine. I made the garage do it while it was in for the mot lol
Re: Electrical problem - ben87 - 17-03-2012
ill take it off and give it a good cleaning firstly then if it keeps happening ill grab one,think they are cheap as chips anyways cheers matt,thought it would be there but wasnt sure if it was something else again will go sort it now i think and see what items i got to service the car same time lol
Re: Electrical problem - mark_airey - 17-03-2012
Speedo sender unit is on the dif part of the gearbox just above where the drivers side drive shaft goes into the box
white sensor held in with 1 allen bolt IIRC mate

Balls it means I got to jack the car up haha will do it now then
Re: Electrical problem - Niall - 17-03-2012
Don't have to jack the car up. Take your air filter hospusing out if you have one and you should be able to get to it no problems.
Re: Electrical problem - ben87 - 17-03-2012
yea had a look niall and got to it,cant undo it as i need a small 6mm allen key which i dont have at the mo. unplugged it and soasked in wd40 and see how that works first of all..whilst i was there i found my pipe next to the cam (which goes into the air routing) was off so put that back on also,that probvs aint helped things and makes sense why my arm is black

Tbh I don't think they clean up. I think it's a internal fault but it's worth a try! There easy to get hold of if you need a new one and I think there even quite cheap from pug. Let me know if you want me to have a look if you don't have service box.
Re: Electrical problem - haggis@home - 17-03-2012
were you driving and recording at the same time ?
Electrical problem - ben87 - 18-03-2012
Yes I was driving at same time, yea it happened again after I cleaned it,they are bout £20 on eBay.
Naill if you could please mate I won't have a chance to access SB till Tuesday
Re: Electrical problem - Connor - 18-03-2012
Mine does this too lol and you can definitely feel the difference in power lol
Re: Electrical problem - cully - 18-03-2012
epic 0-60 time
im guessing fuel magnets and an electric turbo ???
Re: Electrical problem - Poodle - 18-03-2012
Lol@ Cully. But yeah, speedo sensor, would recommend genuine or decent oem manu replacement rather than ebay fella.
Re: Electrical problem - Niall - 18-03-2012
Apeed sensor - P/N 6160 70 - £52.25.
Bit more than I though :/
Re: Electrical problem - Grant - 18-03-2012
Mine does it quite frequently. Need to replace the speedo sensor but haven't been bothered yet lol
Electrical problem - ben87 - 18-03-2012
At that price cheers fella....going to have to be eBay this time
Cully - sheep fuel mate
Re: Electrical problem - Eeyore - 18-03-2012
Mine does this. it doesn't fluctuate at the bottom. It just sits there! Cant really feel the loss of power however normally im driving down liverpool streets past speed cameras petrified of being caught speeding!
Electrical problem - ben87 - 18-03-2012
Had high speeds 60mph etc you feel the power straight away. Lost it once pulling out and that was scary

Re: Electrical problem - ben87 - 10-04-2012
changed the speedo sensor and now its not working at all!!! changed it back to the "faulty" sensor and now thasts not working either FFS!!!!
Re: Electrical problem - Niall - 10-04-2012
Sounds to me like a faulty wire down by the back of the engine. Time to get the multimeter out!
Re: Electrical problem - devils_fuel - 10-04-2012
or it could be the plastic ribbon on the back of the dials with the copper tracks in, i have the same with my rev counter and speedo...sometimes you have dials, other times you don't.
I just need to get a set of broken dials so i can peel the plastic ribbon off with copper tracks in it...all my sensors and woring seem ok!

That's a good point. Very easy to check if you have a multimeter!
Electrical problem - ben87 - 10-04-2012
Dodgy wiring at back of dials wouldn't cause me to lose 10+bhp
Re: Electrical problem - Niall - 10-04-2012
Hmm didn't read that. That is weird and weird normally means earth fault!
Check your bay earths. There's one on the box right near the speedo sensor. Also below the accelerator pedal. Give them all a good clean and check for broken wiring.
Re: Electrical problem - Connor - 10-04-2012
The fault isn't causing the loss in power, the lack of speedo is causing the lack of power. Im assuming that the map needs to know the speed as one of the variables to determine how much fuel to inject. So when it doesn't know the actual speed, it goes to a "default" map, kinda when the maf sensor dies, it reverts back to a default map. That's what i assume is happening
Re: Electrical problem - ben87 - 10-04-2012
yea connor sounds about right..it feel more than 90bhp but it certainly aint 130ish lol
so maybe my clocks/dials are to blame then???
Re: Electrical problem - Niall - 10-04-2012
No they won't be. Speed sensor goes to the ecu and dials get there Info from the ecu.
