X5 30d won't start please help

Post by Tommyx5msport » Thu Aug 16, 2018 3:30 pm

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

Glow Plug Controller / relay....if its like my e71 its under the intake manifold, yes you have to take the manifold off, not to bad, took me 4hrs off/on....the code given is for that.

Don't think it would stop the car from starting glow-plug controller that is.
Not sure what the problem is but i am sure you will get the answer shortly.

Im just going on the code supplied, my local indi did have an X5 in, think it was 11 plated, they couldn't find what was wrong with it even after three mobile diagnostic chaps trying, in the end it was transported to BMW..after two days it transpired that both the key transponders had lost its security coding with the ECU.

I will try that aswell many thanks, it just baffled me because when u press the start button u can hear the pumps kicking in, but not do much as a click from the starter.
