Battery replacement
I bought a 2005 Z4 and it seems like the battery may be nearing its end of life. I keep the car in the garage and after sitting for a couple days at about 30-35 degrees farenheit, the car is hard to start. It does turn over, but it seems to struggle. Also sounds as if it is low on oil, which I know its not.
In any case, wondering what the typical life is for the original battery based on your experience (the car is from Mass. and I'm in Pa.). Also, is this something that I should try to get replaced under warranty? Thanks. |

Your right doc. It is an '06. I am at just under 8k/year (28k at 43 months). I'll take a look at the terminals though and consider the tender too. Thanks.

I have a 2006 Z4 3.0i and just experienced the identical problems, in addition to the DSC and ABS lights coming on occasionally on start. New battery solved the problem although it wasn't covered under warranty due to driving history.....not frequently enough. My local dealer cut me a deal, I bought the battery and a tender and they didn't charge me labor for installation. Total bill was just under $270. Now it starts great....problem solved.

My car wasn't used much before I bought it last March. It did have a tender on it but still I ran into issues a few months ago. Dealer ran some diagnostic on it and got a code that was covered under warranty. No problems since.

My '03 still has the original battery - 38,000 miles driven about twice a week. I'm living on borrowed time I think.
How does a motor that's low on oil sound? You may be hearing valve "chatter" due to oil draining away from the head after sitting for an extended time. Hve you checked the oil level? If it's truly low on oil, the sound you would hear is the motor self-distructing. |

The oil level is indicating that it is full - "OK"
The sound, to me, is more of a metal-on-metal sound, or a poorly lubricated engine sound. This may actually be the case until the oil actually starts circulating and warms up. |

All due respect, take your car to a mechanic you trust before YOU RUIN THE ENGINE. A forum is not the place to diagnose something like this.

dillrob, I have an 06 Z4 3.0i and just had the cylinder head replaced under warranty. The N52 engine has had a few issues with the oil circulation around the lifters (not a technical guy here) and results in a "ticking" sound when starting and randomly after warming up at least in my case. BMW has a service procedure designed to address this issue and if it doesn't work after a couple of times, the dealer can ask BMW to replace the head. In my case, persistence paid in following the suggested service recommendations. I think I may have posted on this post under "ticking sound after engine start up" and got some great recommendations from other members.
