My car sometimes runs like crap so plugged in and code 83 pops up which is Crank Shaft sensor. Also MAF and O2 sensors cum up but only because there out of sync because car is running crap!!!

Have ordered a genuine sensor from BMW @ £85 and am going to replace tomorrow but where is it located???

I can see where it plugs in next to cam sensor but hard to see where wire goes looks like it goes to the back side of the engine but BMW said it should be at the front???

98 registered 523i M52

Thanks in advance guys :)
