Shit-Hydrolock?
 

Yesterday I was unable to start the X, because of what I assume is a dead battery. I have not yet jump started it.

After some reading I am afraid that this may be CCV related.

How do I know if this is the battery, or if my engine is already screwed because of hydrolock?

When I turned the key, it made the clicking nosies, and all electronics and indicators worked.

After repeated attempts I drained the battery pretty much fully.

Is there something I can check for before attempting to jump start, so that I may avoid further damage if it is the CCV?

Advice please?

For anyone who was interested:

I dodged the CCV bullet for now. A friend helped me jump start, it took a while because the battery was completely drained. Key is now dead. Friend probably had a good laugh regarding the German engineering that is BMW, while he sat in his Dodge.

I had to jump start directly from the battery in the back because I was boxed in a parking space. I attempted the manual tailgate opening procedure. It did not work. I had to remove the tire, cover, etc from inside with the seats folded. What a bloody horrible design, thanks BMW.

I drove for a good hour after jump starting to hopefully fully recharge the battery and burn off some moisture.

Temp gauge still out of whack.

When is that far dead you will need to put it on a trickle charger. The alternator alone will not charge it all the way. Get the battery tested and see if it's still good. Good luck, it most likely the cold weather.

Thanks for the response.

If it happens again, I may have to opt for a new battery. Frankly it is due for replacement, I am pretty sure its the original battery.

Battery in the trunk is a great design! What other make can you jump from the front AND rear?

As for the electronic latch.. Not the best design but its industry standard it this point.

The tailgate should have opened once you pulled the green wire, as described in the owner manual. It doesn't pop like the usual opening, it just needs a push from the inside.

I wouldn't wait for it to happen again - just change it out now and def. before the real cold weather hits. If that is the orig. battery then you were on borrowed time anyway.

hydrolock is when you have liquid in the combustion chambers.

You will need to reinitialize the key fob,search for the threads here,I've done it twice myself in the past.All the keys need to be done sequentially.Otherwise your starts locking/unlocking and a spare one stops.
