If the battery was the same specs. as the BMW battery that behavior is illegal in all 50-states. A simple filing in small claims court would have won you damages. It's extraordinarily difficult to void a warranty in this country. I've written about this many times (search my threads).

You can do whatever you want to your car, within reason, without fear of voiding the warranty. Don't let some BMW tech with a junior college degree (if that) tell you what you can and can't do with your vehicle. You can put any brand of oil in the car, any brand of filter, etc. As long as it meets factory specs or exceeds factor specs., you're WELL within your rights.

In court, these cases are notoriously losing propositions for dealers and factories and they'll back down 99.9% of the time with a stern letter, within an amazingly quick time. They know, and are well aware, of what they can and what they cant, get away with. That doesn't mean they don't try to get away with pushing people around like this all day long. It makes them money, lots of money, which is why when these types of cases end up in front of a judge there are often large punitive damages awarded.

Don't let your dealer push you around like that. You're entitled to buy a battery of your choice, and if it exceeds factory specs so much the better.

If my dealer pulled that with me, I'd file a claim against them the next day in small-claims and refuse to settle, just to piss them off.

That's B.S. and the laws on this matter are as clear and in plain language as can be, for a reason.

I'm sure lots of lawyers lurk these boards and will be happy to add more.

Use whatever oil you want as long as it meets or exceeds factory recommended specs your fine. You need not use the same brand or a genuine BMW filter. That's ludicrous!

FWIW, two things:

(1) The "1" part number seems to overwhelmingly show up on foreign language sites, not English, and,

(2) The two filter cross reference tables to non OEM filters both showed the "1" and the "0" BMW OEM filter cross-referencing to a single non-OEM filter, i.e., these two filter manufacturers consider the BMW 11427788461 and BMW 11427788460 to be the same filter for replacement purposes.

I don't disagree with anything you say (at least for those who live in the US, as the rest of the world doesn't have the Magnuson-Moss Act). However, implicit in your post is the assumption that the battery referenced above does meet the same specs. It may not have.

Oil is easy to meet the manufacturer's specs for. BMW publishes requirements for oil, and API SL or SM usually meets those specs. No manufacturer will require that you use their own oil. The one caution I would throw out is in regard to filters, your last example. BMW can't require you to use a BMW filter. However, they can require you to use a filter that meets the same specs, and those specs aren't published. That means that you may end up having to fight with BMW (or any other manufacturer) about a warranty claim if BMW believe it was caused by your aftermarket filter, and you don't agree. The safest is to simply use a BMW oil filter and air filter, or be prepared for a potential fight if in fact you have a failure that can in some way be related to the aftermarket filter. There aren't a lot of failures caused by filters these days, but I would put filters in a slightly higher risk category than batteries and oil (which essentially have no risk, given the ready availability of published specs).

Just my $0.02

That good to hear :)

BTW when you changed your oil was your original oil filter a 11427788461 or 11427788460?

Oddly enough, I didn't compare the part number to the old filter when I took it out, but just did a visual comparison. However I did check online to see if the part number was right, so I expect it was the "0" that realoem and bavauto show, as those are two places I checked for confirmation and if they had been different, I would have noticed. (bavauto.com shows 11 42 7 788 460)

In regards to the 2 oil filter part numbers, the Internet Parts Manager from Tischer BMW writes:
I'll order a kit soon.

Oil analysis results for those that are interested

The Tischer parts manager is right. The part number of the FILTER is 11427788461 the part number of the kit w/ the filter, etc is 11427788460. And the proof has been in the OP all this time :wow:

Look at the picture of the old and new filters side by side. It's hard to read yellow on white but the part number on both filters is 11427788461. BTW the part number on the new filter is upside down. The last few digits are closest to the camera.

Doh!

Reminds me of the time I bought my first oil filter for the 2008 Ford Taurus. The part number listed was FL-400-SB12. The FL-400 filter was commonly available, but I assumed the "SB12" suffix was a variant of the FL-400 filter, since the Taurus engine was in it's first-year update. After much searching I finally discovered that the "FL-400-SB12" was a bit of a mistake in the manual, and the "SB12" meant it was the part number for a box of 12 FL-400 oil filters.

Doh!
