Ring Antenna

[JIm]

Hi,
I know thete is a thread somewhere on here about replacing the ring antenna but I can't find it.

Caplain paranoia is making me think of carrying a spare, if I can change or use it quickly it may save a day or two in a dealer on a trip.

I was wondering how much they were and how you use the spare, I read somewhere that you plug the new one in but "tape" it to the bars and stick the ignition key through it?

Thanks,
Jim

Just part of your query Jim. Ring Antenna £38 plus VAT.

ITS MORE LIKE £83 ISNT IT??

I have my Invoice in front of me now. Part No. C61.35.7.705.247 Ring Antenna. Unit Price £38 plus Vat. I also bought a Spare Orange Indicator Bulb. Total Bill inc VAT is £46.85

Maybe they've come down in price because they're in great demand (NOPE, THATS NOT HOW ITS MEANT TO WORK)

I got quoted £83 a couple of weeks ago.

Hmm, I got one a month ago for a R1200GSA (2008 model if that makes a difference)
C61.35.7.717.136 £70.94 + VAT

Which leads me to wonder if I,ve been given the correct part. Can anyone confirm the part number, thanks.

 

[JIm]

Ok, thanks,

I did read a few weeks ago on here, and still can't find it, that when you change the antenna, you plug the new one in and have it taped to the bars, I think it is not simple to remove the old one? I cant remember if you have to have the ignition key in the antenna all the time or just "dip it in" then start the bike or have it placed over the top of the old one with the key in?

just picked one up in blighty last week, 38 squid +vat. nice surprise they quoted 118 euros in rennes!

Mike, yours is the old part. You want the one with '247' as the last three digits of the part number. That was issued by BMW the first week in May.

BMW did confirm to me yesterday that the new part is considerably cheaper than the old one.

Given the failure rate on your part number, I would lobby BMW that they have sold you a part which they know full well is prone to failure and demand a refund and/or replacement with the latest part.

Has the sky started to fall!!!

An updated (and hopefully improved) part that is almost half the price of the old (and faulty) part.

Wonders will never cease.

Thanks for that Andy, luckily I have mine on an "return if not used basis" which I thought was good of them, so when we get back from France they can have it back, Thats if we don,t need it of course !!.

 

[Our Gee]

Hey Andy, the last three digits of the part number "are" 247 as in my post above, so I must have the latest type, Yes !!

Can the switch that this "Ring Antenna" closes to allow starting be shorted out?

Then the bike would work like a normal one with a key and no gizmo's

Mike - yes '247' is the latest post May 08 part.

Waldon - I'm not technically astute enough to answer your query. The best I can offer is that my understanding is the Ring Antenna simply talks to the Immobiliser to confirm it likes the key and that the immobiliser can tell the system to start the bike. All of the posts I've seen on this site seem to suggest that to by pass the bu**ered one you need a new unit and a spare key.

If you can find a way of doing it by shorting the system out I'm sure that there are a lot of people who'd like to know! I think you might come up against Canbus problems the moment you short anything out, but I'm not the expert.

I don't think the ring antenna closes any switch. It is just an antenna that receives the key code from the chip in the key, which is then read by the central control unit. This then allows the bike to start. A bypass would involve reprogramming, not just frigging a switch out.
