Overheated now won't start

Hello all,
My 05 330 Ci overheated on my way home. I pulled into a gas station and let it cool off. Being it was dark and I had no tools I called for a tow and had it taken home.
Now it will crank but not start. I pulled codes and got P0300, P0303, P0306, P0117.

Any ideas?

Thanks in advance.

The p3xxx codes were thrown when the engine was still running so they aren't relevant.
P0117 says the engine temperature sensor is shorted to ground. I don't know if this would prevent starting.
Try disconnecting the sensor.

Thanks for a quick reply.
Can you direct me to the temp sensor. I'm not new to cars...just to THIS car.

How far did you drive it while it was at higher than normal temp? Any sort of overheating is the kiss of death for this engine.

My 528i survived couple of gently driven miles with a stuck closed thermostat.

The temperature sensor has a negative temperature coefficient. Low resistance means high temperature. My guess is, due to the short the DME thinks the engine is hot and it doesn't inject enough fuel to start the engine.
Check the engine temperature in the hidden menu of the instrument cluster.

Maybe yours didn't overheat, just the temp sensor went crazy.

You are describing a seized engine...due to catastrophic 'over-heat' and combined oil viscus starve....however short lived.

Anything...and everything...is NOW within grave question for the integrity of your BMW engine.

If you are an Irishman...you might have LUCK!

I too am hoping here!

Depending on his skill, he may find the way to turn the crank.

Honestly, it is a challenge to find any entry to actually turn the crankshaft on not only BMW but almost if not all modern cars today.

If he is not a moderate back-yard mechanic, he needs help.

Thanks for all the input. Let me repeat the symptoms. The engine WILL crank and sputter as if it will fire. I tried to crank while the accelerator pedal was floored to get maybe a "limp mode" start. to No avail.
I have many years of experience with cars and do my own work on my others. This BMW is new to me. This engine is most certainly NOT seized. There is no evidence of coolant in the oil nor oil in the coolant.
While I cannot rule out a blown head-gasket or warped head, I'm intrigued because the engine appears it is attempting to start.
Thus the inquire ....I'm just wondering if there is some simple issue indigenous to BMWs that I'm not aware of. I have intention to try disconnect of the temp sensor as advised by acoste. I will have to go to the cars location.
Thanks again to all who offered info.

Easier to read the temperature on the hidden menu first before disconnecting it because it is underneath the intake manifold. Hard to reach.

According to the wiring diagram, the one in the rear under the intake checks the coolant and the one on the oil filter housing checks the oil temperature.

When you are cranking the engine is the sound it makes while turning over about the same as before the incident.

Yes Rusty...the cranking sounds are normal. Nothing metalic. NO knocks, bangs, tapps or clunks.

If not for the overheating, this would be a nondescript crank/ no start issue.

Perhaps I should look at it as such. Being unfamiliar with BMWs I was wondering if there was some odd occurrence that was common such as ( when overheated, the CPS fails and the result is a no start. For example.)

Thanks to all for your input. This forum has offered info much quicker than any other I am member to.

I'm lost too. Good that it is not seized shut, but damages detrimental should not be ruled out.

An examination, or survey, by qualified, should be a next move. Here you will receive a good news, or bad news report...and you will have to pay to get this info...but you need to know whether to bait or cut bait! I'm rooting for you...Good luck
