Splondike Posted February 13, 2020 Report Share Posted February 13, 2020 (edited) Hi all, my little track hearse is playing up. I have not used it for about 4 weeks as I have been unwell, went out yesterday and have the DSC, Handbrake and ABS lights are on and speedo not working. I have had a read up and I know the wheel sensors can cause this ( they were renewed a few months ago and no issue until now ). Also I noticed the blue and yellow wire in the second picture is not connected to anything, could this be related ? as I have not noticed it being adrift before. (before I start removing wheels and checking sensors) Thanks in advance for any assistance Edited February 13, 2020 by Splondike Quote Link to comment Share on other sites More sharing options...
E46Driver330Ci Posted February 13, 2020 Report Share Posted February 13, 2020 Easiest to read the codes with inpa, then there's no need to guess. I can't remember precisely, but I guess 3 lights means the DSC unit. Quote Link to comment Share on other sites More sharing options...
Splondike Posted February 13, 2020 Author Report Share Posted February 13, 2020 (edited) Thanks, so you don't reckon the wire has anything to do with it? Ok, what about the passenger side rear wheel sensor, I thought that could cause what I am seeing, including lack of speedo ?

E46Driver330Ci Posted February 14, 2020 Report Share Posted February 14, 2020 A code reader is a lot cheaper than throwing random parts at the car. The chance of the internet people knowing what the wires are for is very low. So you will have to go find the wiring/circuit diagrams and read them yourself. If the speedo was working 4 weeks ago, and you didn't cut the wires yourself in the mean time, then the wires can't be responsible for the speedo problems. momo 1 Quote Link to comment Share on other sites More sharing options...
Splondike Posted February 14, 2020 Author Report Share Posted February 14, 2020 (edited) Fair point, ok mate thanks. I was clutching at straws a little. Edited February 14, 2020 by Splondike Quote Link to comment Share on other sites More sharing options...
E46Driver330Ci Posted February 14, 2020 Report Share Posted February 14, 2020 (edited) A cheap £5-£10 inpa reader is all you need. Since china is out of action currently, you should go for a local stock seller and pay a bit more. Don't go for a generic reader, it will be useless. To use it, you'd need a laptop, or windows tablet. Edited February 14, 2020 by E46Driver330Ci Quote Link to comment Share on other sites More sharing options...
dontpannic Posted February 14, 2020 Report Share Posted February 14, 2020 If you own an E46 the best investment you'll ever make is INPA. I've had my trifecta of lights on the way back from work yesterday, plugged my INPA cable in and got the exact error within seconds. Quote Link to comment Share on other sites More sharing options...
Splondike Posted February 14, 2020 Author Report Share Posted February 14, 2020 Ok I've ordered one from UK with cable etc. I am fairly IT literate so hopefully will be ok. Guess it will be handy for the E36 too, not so much for the E28 Quote Link to comment Share on other sites More sharing options...
E46Driver330Ci Posted February 15, 2020 Report Share Posted February 15, 2020 You mean to say you have been doing random parts throwing at your cars until now, huh? That's impressive Mr rich guy. The E36 has a round ODB connector I think. You would need an adaptor. Quote Link to comment Share on other sites More sharing options...
Splondike Posted February 15, 2020 Author Report Share Posted February 15, 2020 No, they just have not gone wrong before Quote Link to comment Share on other sites More sharing options...
Splondike Posted March 31, 2020 Author Report Share Posted March 31, 2020 Both rear ABS sensors had been replaced recently (with cheap and nasty ones). So I removed and cleaned out the hubs with brake cleaner and an airline. This brought the speedo back to life but lights still on. I bought a new sensor for the drivers side from BMW and replaced it and now all it back to normal. So buy cheap, buy twice as most of us know. I would not have put cheap and nasty ones on myself but hey ho its working now. Next to replace the cheap and nasty throttle cable that was also renewed at the time as the sensors and has also broken off at the pedal end ! Will get one from BMW when they re-open. Next to install the harness bar and carry on with the weight loss program ! Stay safe everyone. Quote Link to comment Share on other sites More sharing options...
