Hi guys, I’m totally new to this forum, and this is my first forum entry ever. I hope an entry under this forum is the right kind and wise help to get. I’m Dane and that’s why my German is not flawless, but hopefully it’s enough to participate in this forum. My problem is like many others the vulnerable ABS on my BMW R 1150 RT. I’ve read a lot of things about the others in this forum that have also tried different things n not to buy 2000 EUR or more in the BMW contract workshop. Like many before me I also have the blinking of the 2 control lights (ABS and warning symbol). ABS lamp clocked in 4 seconds. Warning lamp is on. I have read about the possible errors causes (moisture damage, defective components, capacitors, rust on the pistons etc.) The question is however, why does everything work with me when the motorcycle is cold and does not have a certain heat – self test before starting n (brake lever and foot pedal tested many times over 10 minutes) and after the start of the engine everything went still OK (many times tested as before the start of the engine) – but after 5-7 minutes lesson run 600-1500 around (can unfortunately not drive in the weather – too much snow) the warning lamp starts to flash again in 4 seconds. After 15-20 minutes cooling everything is OK again – no ABS flashing and selfest OK. Incidentally – brake fluid has been changed 4 months ago. Hope One of you has an idea. Greet Steen
