540iA stuck in 1st and 2nd gear
So I was out tonight, driving the 540i and it was fine. I was driving for about 4 hours, not roughly or fast but driving the whole 4 hours. The gearbox then suddenly at around 50mph went into 2nd and refused to shift out. I put it in Steptronic and it would still not go out of 2nd. It'll go into first but not third, four or fifth. There is no check engine light, ABS or traction control light. This literally happened 20 minutes ago so I haven't had the chance to see if "letting it cool down" and starting it tomorrow will fix the issue but I'm really scared now because it wasn't a pleasant experience driving in a 80km/h zone in 2nd gear at around 40km/h. Luckily I was close to home and so I managed to snail it home at very slow speeds. The roads are clear at night which is good. What do you think guys?
