BMW Brake Fluid warning message on
 

BMW Brake Fluid warning message on. What needs to be done? I took it to a shop that does Oil change, they said they can't assist. I took to a mechanic he said add brake fluid. But I don't think he knew what he was talking about. Any Ideas

2009 4.8 X5

Can you post a picture of what you are looking at?

The E70 has a bunch of different warnings to include "Service" notifications. There is a Service Notification for flushing the brake fluid every 2 years.

Make sure what you think is a brake fluid warning is not just a 2 year Brake Fluid Flush notification.

You can access the Errors/Service notifications in the iDrive system.

You've got two places that can SEE the warning and they dont know, yet you think we will know from 'brake fluid warning'?!?!


TAKE A PICTURE.

Or, if that is too much- you can google images, find the one that matches ad link that here

Don't have a picture right now, but is here. This one is green, but the message is red here under brake fluid

Standard CBS based "brake fluid needs to be changed" warning.

So get a brake fluid flush.

It should be in the owners manual too....

BMW Service : Service from BMW : Condition Based Service (CBS)

Time to dive into the owners manual and learn about your vehicle.

X2, however, are the shops that you go to qualified to work on your 4.8? I'd be careful because it is a pretty complicated motor...seems like a pretty simple diagnosis

This issue is so utterly basic...that 'complicated motor' isnt the issue. These bottom feeder, idiot tech, cheap crap shops should never touch ANY car.

LOL And we're not talkin' about Jiffy Screwed

Born and raised in NYC.

'Car Service Center' by day, chop shop by night.

It is funny how the desire to 'find a cheap place' or 'see if I can get some free advice' results in people going to some very sketchy places. Combine that with people not knowing much about cars, and almost anyone in greasy pants looks like an automotive genius.

;)

OP excluded of course!

so what's the DIY procedure? I searched the forum but could find none, is it the same as on the older Bimmers like our e39s (I know you are also on m5board, I'm Brent_M5) and use the Motiv pressure bleeder at @ 15psi? I'm assuming so but this is my first BMW build after 2000 and it's clearly more tech and computer/module heavy so I'm still lost as to what that increased complexity does to previously simple procedures (like swapping a freakin battery being "hard" now)

In my very humble experience 2 years brake fluid interval is bit overkill.

I do my own (someone inside doing the old school "brake - open bleeder - release - pump 3 times" routine), and quite frankly if I go every 2 years I have a hard time distinguish the new from the old fluid when it comes out. So I reset it and do it every 4...

But obviously to each his/her own...

typically brake/tyre/exhaust shops do it for less than $100 all in.

Out of interest re fluid changes:-

Years ago when main dealers and manufacturers started suggesting 2 year fluid replacement I purchased a proper fluid tester, one that actually measures moisture content and then boils a sample to test it. I have yet to find ANY vehicle where the fluid is anywhere near out of spec even after 4 years of not being changed! YMMV

That is very insightful, thank you for sharing...
