Ecu Change????

I just bought a 04 GT and have been reading the posts about ECU replacement. Can someone explain what this is about?? My GT only has ~2000 miles, cuts off a few times when I first start it in cold weather, dies when I try to give it throttle when I first start it, and smokes like hell when I first start it up. I am new to BMWs and not sure what might be up with this. After it warms up it is fine. I saw some previoue posts about the ECU and some of my symptoms, and about a replacement from the dealer. Any help would be greatly appreciated.

Get down to ye olde BMW shop and get the ECU replaced - pronto. Since you're not the original owner and probably don't have a strong relationship with the dealer you should do this before the end of the year. It is not a recall but a "technical service bulletin" # 13 00204 057 (Covers 03/04 K1200RS/GT models). Mention the cold start off-idle stumble and you qualify.

The smoking on start up is because you park it on the side stand and/or do not keep it upright for 30 seconds or so after you stop the motor,to allow the oil to drain back to the sump.
Congrats on your purchase!!

The ECU replacement is free by the way.I think it is for all 03 and 04 RS/GT built before April or May 04.

RUN, don't walk, to your nearest BMW dealer and get the ECU replaced before 01-01-2006. I just had mine replaced this week. The symptoms you describe are most certainly ECU issues. Once replaced, the stumbing and throttle hesitation will cease. As most who have had ECU replacement reported.."It runs like a new bike!" As an added benefit you will realize a noticable increase in your gas mileage.

Don't tarry.....and Good Luck!!

ECU change

Hello guys,

I ride both a 2003 K1200RS and a 1991 K1, and this forum helped to solve a serious problem for me. I bought the RS when it was 18 months old and had 800miles on the clock. When I started the machine it would not idle like the K1, but I thought that it would come 'once the machine was broken in'. This has not happened and when I looked on the Internet for a solution this site, this forum made me aware of the ECU problem. Thanks to you guys I made an appointment with the BMW dealer in Den Bosch (the Netherlands) today to have the ECU replaced under warranty.
As I have had problems with my K1 in the last year I know how much it costs to have the Motronic unit replaced - in my case more than 1000 euro's or some 1200 dollars.
The K1 is well worth it: I consider it a machine with a more 'sporty' character than the K12RS. IMHO I can go around a track faster on the K1 than on the K12RS (never tried it though).
again: thank you guys for the information.

Kind regards,
Frits van Straten.

regards, Frits.

If you can laugh at your own stupidities, you have fun all year round!
