Hello and welcome to JustAnswer BMW,

My name is XXXXX XXXXX it will be my pleasure to assist you today.


what does it do when it does not start?

Customer: replied 4 years ago.
Not much all of the lights
R on in the dashboard it seems to act normal

but you say it doesn't start


so you press the button, what exactly happens when you press the button and it does not start?


does the starter motor turn over? does literally nothing happen? do you hear noises? etc?

Customer: replied 4 years ago.
Starter does not turn , the only noise I hear is like a clicking sound like maybe a relay or something

do you have the last 7 digits of the vin available?

Please do not select either of the two lower ratings - please reply if you need more information








even if you "expected more" in terms of good news, please do not select a low rating as it PUNISHES ME for my honest answer.









your symptoms point most likely to a failing / failed IVM module (integrated supply module). This unit contains the starer relay.


this is a very common cause of an intermittent no start on your model / engine (as confirmed with your vin).


A replacement IVM is about $120. it is located in the electronics box in the engine compartment


Remember, a low rating PUNISHES me for my honesty - thanks.


Please use the "reply" or "continue conversation" link if you have further questions. Otherwise please select a positive feedback rating (FAR RIGHT) so that I may be credited and compensated for the assistance I have provided.
