The dealer I work for has some advisers that have been dealing with the same customers for over a decade and are great to deal with, and a few techs there including myself have customers that request us only to do their work. You can fix the situation, and the service department is usually happy to do whatever it takes to remedy bad experiences.

Very true- but from a civilians point of view it is SO HARD to manage the relationship. Often times the dimensions of your screwing only become apparent later, and the dealership 'closes rank' to protect their own... most owners are clueless, and just have to trust what they are told... they don't even know when to ask for help or other opinions...

Also, you work at a good shop. There are some toxic dealerships out there, with predatory policies that induce dishonest SAs to 'shade' the truth and maximize their income - in competition with other SAs to save their jobs.

You're lucky and I'm lucky. But many are not.

Yes, we can choose new SA and new dealer. But, what if you are living in a small country like me? Only one BMW dealer in the whole country. Atleast my SA is very helpful and honest. Hope that my car will not have high battery drain message again.

Pick my X5 up yesterday and it seems to be fine. New battery is in black unlike the previous one which was white. The only thing I notice is that the dome light turns off much quicker than before. Other than that my X5 still run great.

The battery was switched over from lead acid to AGM, and the vehicle was programmed for the retrofit. The AGM batteries are better but use a different charging profile from the lead acid hence the programming. And the software also changed up a few things to help with power useage as well.

Thanks Weasel!
Can you please enlighten me about AGM battery? What is AGM stand for anyway?
Is it the same like those maintenance free drycell battery in the States?

Good luck but my 07 X5 4.8 stayed 8 weeks in the shop over several vists for this. The dealer when stuck has to do the steps that BMW wants them to take and they are very slow. Mine was just waking up and drawing too much current. It does wake up every 70 minutes or so to check on itself.

BMW ended up taking my car back but it took pressure in the form of a lawyer and writing to Munich. That said my 2010 X5 3.5D has been flawless for 4 months now and it was at no cost to me.

I think they concluded it was a battery computer module on my old X5 but they always replace the cheapest parts first. I was on my third battery.

Here's a helpful link to tell you just about all you would need to know about the different battery types and what all the different numbers/ratings mean.

The battery/electrical bug has hit my 2010 35d.
Battery holds a charge for an hour and no help until Tues at the earliest.

Wish I had my old truck back.

My 2010 had the battery discharge the first night I brought it home. I played with the settings and after a few nights I was finally able get it to go away by changing the pathway lighting setting to 0. I've only had the message come back one time and the interesting part was that was after my dealership installed and programmed my hitch. I check and sure enough my setting had been cleared with the new programing and pathway lighting was back on. I turned it back to 0 and have never ever had the problem again.
