How do you get at the cog? Is it easy to take the unit apart?
I can open the "inspection hatch" on the side of the unit but can't see any broken cog teeth. Happy Easter, all John

A lot of effort went into this, but costs would be too high.
We contacted the commercial division of one of Melbourne's leading universities.
The idea was to re-manufacture the cogs in metal using 3D printing. When I was at their premises, they were manufacturing a part - incorporating three different alloys - for an aviation company. The staff told us that all their 3D printers are from Germany and that the aircraft part would take 24 hours to complete. At the local International Air Show (it is a biennial show) they displayed a working jet engine that had been totally made on their 3D machines. One of my fellow club members later discussed the proposed manufacture of our cogs. We didn't want plastic as there is quite a sudden impact when the gears reach the stop "buffer" - I liken it to a rail vehicle hitting the buffers at the end of a line. My son-in-law prepared a set of cogs in plastic - only for checking against our drawings. We intended to have the cogs made in a strong metal that would withstand jarring - the company uses titanium in a lot of their work. However, considering the time to clean-up the prototypes - supports have to be included in the programme to hold parts during manufacture and later, these "supports" have to be cut out and the items cleaned up. We would have had to place a minimum production run to reduce costs and even then it was considered that members would prefer to continue with the second hand plastic BMWs units - whilst these remainl available. I did consider placing a photo of the two main cogs - formed in a blue plastic. Saddened by the fact that we couldn't get this project off the ground - after so much effort. |

I am happy to print them out. I believe John Chambers from the SA Rover club is going to bring some over to the Australian convention this month for those in Oz that might be interested.
I considered printing them in metal but was concerned they would then damage the smaller cog instead. That is a much harder one to replicate so I stuck with plastic. I can print the plastic at home as well so it makes them a lot cheaper to manufacture. Without making this an advert they don't cost much ($16 AUD ea) but the postage is $8.50 anywhere in Australia for up to 500gms so as they don't weigh very much at all it is better to combine orders through clubs. I am also happy to send o/s but don't know the postage costs. Anyone who wants one can send me a message. Cheers Last edited by Ameph; 3rd April 2018 at 07:49.. |

I have developed a problem with the abs and brake warning lamps staying on when engine is running, when I first switch ignition on I used to hear like a self test whirring I think coming from the traction control unit. Is it possible that this unit has failed as thread describes or am I clutching at straws ? Any help or advice would be very much appreciated.

Hi Andrew Thanks.... that would be good. I might try to remove my unit, open the inspection flap and shake it to see if any teeth fall out! I've read somewhere that if that happens the unit may still work. Will have to see! Cheers f'now John

Sorry, I can't help as the car is new to me, my previous one didn't have TC and my TC warning light (only) is always on. So I don't know if I should be hearing a self test whirring sound! Hopefully someone more experienced will come on thread and advise. Good luck! John

Hi Ameph, I'm very keen to buy 2 of these cogs that you have re-manufactured - with hard to get parts I always like to have one as a spare. How do I go about ordering and paying for 2 cogs? I am in Boronia Vic 3155. Cheers, Bill
