885i IGNITION WOE

[sTe140Ve]

I took my 1999 885i to the only place within 70 miles of home, that had Triumph diagnostic kit. The bike had a running problem (engine warning light showing). Their diagnostic showed a fault with the ignition coils. They ordered a new set of coil packs and when they had not arrived after 10 weeks I bought and fitted new ones myself. OK so far, except there diagnosis was not completely on the ball. I still have the fault and the bike is getting increasingly hard to start. I bought a Dealertool DIY diagnostic program that shows all 3 coil packs are "open circuit". The wiring diagram for this bike completely bamboozles me - Does anyone have any suggestions as to what I could try next? Cheers!

Get a copy of Tuneecu (free download) and an appropriate cable. Do a search here to find out what it does.

I would be very surprised if all 3 coil packs went down at the same time. Your dealer sounds (sadly) rather typical.

Is it showing them open circuit with the engine running??

Thank you Ian. I have not heard of Tune ECU before but I will be downloading it shortly. It should be a useful tool for future problems as well.

In reply to Bob - I assume that the "open circuit" condition is present with the engine running because, on one occasion the warning light came on whilst I was riding.

Other thing you might want to look at is the Underside of the ECU and the plug(Just 1 on the 885?) and contacts, I think on the 885 they are in the same place and if the holes in the mudguard havent been sealed, well,  a few know what can happen

Thanks, I'll be having a look at that.
