    2nd Crank Sensor failure in 6 Months...

    Cheers chicaneuk, to be honest I normally take that approach with most bolts etc.! - I expect there are compression limiters in the part to stop it being crushed at least so should be ok, I'll potentially be doing it tonight....I'll try to remember to feedback on anything I find!

    Incidentally does anyone know the torque value for the thermostat housing bolts? - I don't have a bentley manual etc. for this....

    You would have thought BMW would be right on top of that wouldn't you? - unless there were some obvious downsides?

    No stress, part was only 12 quid and I've disturbed it twice already doing the crank sensors, I'll check out the hose situation, I can't recall if my M52 has the plastic hose connections or is standard old school rubber hoses and jubilee clips...

    Have you had a diagnostic on it to see if CAM / Crank sensor fault logged?

    Febi one on its way! Can't hurt to swap it out anyway as preventative maintenance if nothing else.

    Hi Gents, I may look in to replacing this (Thermostat housing) then as Mine is 21yrs old and original I think!! Mines not a TU, just a single Vanos job which I think has a slightly different design but might be wrong, but the housing is still plastic, and coolant does disapear even after hoses and radiator etc. have been replaced. I'll have a look at costs...

    Hi Keliuss, Good call, I will have a look mate, I had to loosen 1x thermostat securing bolt to remove the front lifting eye to route the wire so this could be the case.... I will check to see if there is a leak when the missus gets home. By the way BMW UK don't want to know, told me to take it up with the stealership as they are all privately owned and set their own costs and rules.....Well done them for not giving a crap!

    Maybe coolant temperature sensor saying the car is too hot?

    I've e-mailed BMW UK explaining the situation and asking what they'd like me to do! - We'll see...

    One thing I did notice was how stiff the sensor wire had gone even though only 6months old, I guess a bit of thermal degradation to the insulation is to be expected but surely a more suitable insulator material should have been specified considering where it sits!

    Hmm, thanks Clavurion, I'll look on Realoem for the part numbers and ask if BMW want to supply the updated set maybe FOC! - Yeah right
  13. Hi Guys, I had what I assume to be the original 1997! BMW crank sensor fail back in May I think, duly replaced with a new genuine BMW part at £123 and now this one has failed checked on me laptop, also same symptoms as before..... So thinks me, I'll call up the BMW parts dept that I bought the sensor from to see how to go about warranty replacement etc. - So says they: 'You have to bring in the vehicle for diagnostics check, if it shows faulty sensor then we will sort it and diagnostics is free, if not you have to pay for the diagnostics.' I asked if they can perform a bench test of the sensor and I was told 'no, it must be on the vehicle in case it is a wiring issue etc...' (Surely a bench test of the sensor would make more sense as it rules out wiring issues?) So I asked them if they keep the sensor in stock as last time it had to come from Germany, 'none in stock and we won't order it unless you pay for it...' And then I asked how much the diagnostic check is.... '£168+VAT'!!!!!!!!!!!! WTF - how much!! - I confirmed that would be the cost even if I just want them to look at the crank sensor signal only! So effectively to keep continuity of driving my vehicle i need to stump up nigh on £300 You can drive it but it has stalled a couple of times and mostly the Mrs and kids are in it. Sod that, so I bough a HAAS unit for £58 and swapped it in, car fired up straight away and all fine. fearing a wiring fault and me fitting the new sensor just nudging wires back in to contact etc. I swapped between the BMW and HAAS unit 6 times and the fault 100% followed the sensor so I am as sure as can be the sensor is faulty. So, am I being overly sensitive! - It's an old car and not many seem to appreciate them anymore, everyone just wants a range rover on hire purchase etc. but customer service seems to have been lost a bit here really, so I'm thinking of writing a slightly pi$$y e-mail to BMW UK demanding they bench test the sensor or send it to the OE supplier to test and then refund me the cost... Anyone done this before? - Any luck? - I want my £123 back! - or another BMW part at least for when the HAAS one fails! Can the ECU kill its own sensors? - The one I removed seemed ok, no damage to sensor, wiring or plug... was it an inside job!

    Btw e39 525i cuts out....

    Doesn't sound like fuel filter issue to me really. Fuel pump itself then maybe, not the relay. When you say it runs fine at high revs is this under load or just revving in neutral? When it re-starts after 5 or 10mins does it start immediately or after a few attempts and is there a strong smell of fuel out the exhaust? I assume you haven't had a diagnostics scan done yet? When it stops after 5mins does it start to missfire and run rough or is it like someone turned off the key?

    Be careful that you get the right prop as 328 box is longer than 325 from memory!
