Starter Motor Delete

    Just a warning for anyone with a right hand drive V12, BMW no longer have any starter motors for this car worldwide. I just obtained the very last one for a CSi I have here at the moment. Just as well maybe at £375.00 plus VAT each!!!


    It will therefore be up to the aftermarket now to attempt to supply this and with it being such a limited market, I would expect it to be all special order.


    I am ordering one from BMW Germany as a back order - no delivery expected just in case they find one for my CSi as a spare, she's a bit hefty to bump start and thats just the ex-wife!


    Hopefully BMW will have an agreement with Bosch to supply these in limited quantities through the BMW network but don't hold your breath for delivery times.

    That's interesting to know. thanks.


    Electrically, however, the starter motors are not difficult to service. Brushes and bearings can be replaced and armatures rewound. Pinion gears may be a bit more difficult, though.


    I guess the CSi version is the same as other 850's ...or even 750's?

    Yes, same ones are even cheaper on ebay US, but I wouldn't trust one of these to work for much more than 5 minutes.


    If I really needed one, I'd find a used one and recondition it.


    Same thing with just about any automotive part these days. I bought a Bosch MAF sensor a couple of months ago, which when it arrived was clearly a clone, and a badly made one at that, when compared to the original. The ends were not even round and the filter mesh was not on straight. But you can get these in bulk, directly from China, for USD 10 each, so...


    (Even found cloned "Yamaha" flutes when looking for a flute for my daughter. You neme it, they'll make it.)


    Of course, the worrying thing is when it gets to safety-critical items such as brakes and suspension components ... and there are plenty of those offered on the 'bay.

    Chinese MAFs, O2 sensors etc are useless. However they are sensitive measurement equipment, a Starter isnt nor is it a complicated device by design.


    Even if they worked for 60k miles vs 120k, at £80 you are still well ahead of OEM RRP and if there are no OEM models, then its a no brainer.
    However I have no idea how difficult or time consuming it is to replace the starter on a M/S70, that would be a key part of the replica part consideration..?

    Unfortunately, ECP and GSF also sell these items in a nice retail box, for alsmost the same price as originals. After seeing it, I sent it straight back for a refund.


    Does anyone know how to get genuine Bosch, non BMW stamped MAF's and O2 sensors?


    BMW just simply add crazy markups to these parts

    Unfortunately, the MAF parts for the 850 are no longer in Bosch current production, so it's down to whatever stock is left in the BMW warehouses or 3-party "equivalents" (read made-in-china). MAF technology has been changing radidly. The 850 versions are probably 2nd generation and have real platinum wire. We are now at 5th+ generation and the new versions are modular (one sensor, different housings) and use a thin-film sensor. It may be possible to find a modern MAF sensor in the Bosch HFM-5 range with similar output characteristics, if not precisely the same. The engine ECU will in any case self-tune itself to some extent using the lambda sensors in the exhuast.


    I think the lambda (O2) sensors are still easily found as Bosch generic versions, although you may need change the electrical connector to suit.

    You think its bad on the 850, try the CSi! I could get Bosch Reman 850 parts from a Motor Factors no problem, genuine Bosch but no good for the CSi.
    Does anyone have detailed operating range details that could be used to find a similar MAF?


    Also, I was sent this previously, they replicate OEM MAFs with firmware upgradable versions:

    I am in complete agreement with posts 9 and 10 but kept shtumm as I didn't want to sound a smartass against the other posters whom I know well anyway. Everyone to their own etc.


    There is NO WAY I would spend the huge time and effort replacing a V12 starter motor and then give the owner a warranty on my labour with an ebay starter! I wouldn't do it on my own car so I wouldn't do it on a customers car - period. :naughty:


    A 5 minute job on a £50 Escort maybe but not on this. The old one has faithfully done 15 years and thats worth the cost of a genuine one if you get another 15 years from it and the reason this one has failed anyway is a severely worn clutch and flywheel filling it up with swarf and clutch dust.


    Chinese knock-offs are rubbish and you get what you pay for. This CSi is getting done properly if I am doing it unless the owner wants to take it elsewhere for an ebay job. Try doing a labour claim against those ebay vendors if the starter fails! :rofl: You MIGHT just get a replacement rubbish starter AFTER you have stripped it all down again and sent it to them. :motz:

    Gerry I think for many of us commenting on here it was about what the alternatives were not what we would buy. I would alway go for the BMW product if available. The lifters I bought recently from a internet parts dealer were BMW but just a lot lot cheaper (they were in a OEM bag/s) as for my alternator I had it rebuilt by a company recommended by BMW Chiswick because I was worried about the point you were making about quality etc. Like everything in life you get what you pay for and for now at least I save on the labour most of the time so spent the money of the real deal but not everyone has that option. If its the differance between breaking a car for parts or using a third world component the decision always rests with the individual.
    But for now no price is too high to keep my baby on the road (just dont tell the wife!) although I will always check the market to see what the options are.

    :driving2:Its been a year since I sold her and I still miss her.......

    The car with the malfunctioning starter motor Gerry is working on is my CSi. I have been down the road with cheap starter motors before with my Pantera. I replaced the original bulky starter with a smaller high torque unit as they were available from a well known De Tomaso parts vendor for just $110. One year later, while in France, the starter lets me down!!!
    I now have a unit sourced directly from the engine manufacturer, and four years on it is still perfect. It is easy to remove a starter on a Pantera, with a lift it is a 15 minute job, on a CSi it is several hours, you get what you pay for, simple as. I will gladly pay for a OEM starter for peace of mind on a car of this calibre.
    Another lesson learned with the CSi, once you feel the SLIGHTEST symptom of clutch wear, such as a minor judder, or slip, get it seen to. I allowed my car to be used by a friend briefly after the clutch began to judder, along with some noise from the release bearing, with the result that the entire clutch, and flywheel needs to be replaced. !!
