My car doesn't start upon pressing the Start button, if I put the key in and wait a minute before pressing the start button it starts up. Error code thrown in ISTAD is 00A0B4 CAS:Engine start, starter operation.

Battery was replaced 6 months ago and checked the voltage, is there a way to tell if the starter is bad or just the solenoid.

Well, do you have power at the starter when it's asked to start?

Hear a click?

[here] - does the quick fix work?

 

No click can be heard upon pushing the start button and the noise is like as if the car is struggling to start and few seconds later it just dies (no noise at all, pushing the button again does nothing). I take out the key and put it in again (without pushing start), wait for a minute, then attempt to start, car starts up fine. Problem repeats more often when the car is left overnight in cold outside.

Not sure if the one minute wait is letting the solenoid/starter energize enough to start the car.

 

That was the last straw with my old 335i.

In the good old days when men were men and Welsh sheep were very nervous...my Mini 1000 put me thru this crap. From memory there was a dog that used to stick on the flywheel. A tap with a hammer or rocking the car whilst in gear would usually shift it. Also changed the solenoid...but one could easily reach it in a mini to check if power was going to the starter after it clicked. Dodgy earthing was also a factor at one time. The starter motor was dead easy to change too.

Falling that...

If engine is turning over check battery is charged and alternator is charging.
