Hi all, just after some help, I have a 2011 30d x5 which won't start. Battery is fine , ignition comes on. But won't turn over. No warning signs on dash. When you press the start button you can hear the pumps working, but won't turn over. We have had hump leads on it. A local mechanic has tried to read fault codes but the ignition switches itself off after about 30 secs. Eventually he read fault codes and only thing that came il is 49a6 LIN BUS. I am hoping it just could be the starter but wondered if anyone has had similar problems. Many thanks

When we had our x3 it would not start because we had a faulty key.  The car would not read the imobolizer transponder from the key.  Sometimes it would start first time,  next time you went into the car you had to try the key about 50 times.  Bought a new key from BMW and the problem was solved.
I have no idea if this could be the same with the e70.
But it's something to consider.

If you have a second key try it as the car is about the right sort of age to be a dead key
