Ever Had Cold Start Issue?

beemerfreak · 01-09-2013, 03:42 PM

My car is a 2005 545I
I know this is off topic but hopefully I can get help from u guys.
My car has a cold start issue.
It doesn't start under 50 degree weather.
It cranks but won't turn over.
Anything over 50 degrees it starts and drives normal.
No cel.
It currently has no codes but had codes when I first scanned it.
I've changed battery, spark plugs, cam shaft sensor, and IVM module.
We've checked fuel pressure etc..

Any help?

Cold start sensor - my 02 325i just had the same problem.

Crankshaft sensor(s) or software.

mine starts right up even at below freezing. maybe try leaving the key in the on position for a few secs to get the fuel pump running, then start

The fuel pump only needs to prime for a second or so to provide adequate fuel for ignition, no?

Fuel filter would be my guess, it's an 05...
