Replace brake fluid warning.
Replace brake fluid warning.
The replace brake fluid warning light on my 1998 2.8 Z3 has come on and there are still 3 service lights to go b4 the next service. Is it possible to reset it without resetting the lot, if so how ? I don't want to go to a stealer when my friendly & reliable local garage can change the fluid a lot cheaper. Mike Fishwick to the rescue ?

Re: Replace brake fluid warning.
Others may be able to confirm, but i'm pretty sure the brake fluid light comes on when the water content in the fluid reaches a certain limit, when you bleed the system through with new brake fluid the light will go out on it's own, easy job with an easy bleederZedona wrote:The replace brake fluid warning light on my 1998 2.8 Z3 has come on and there are still 3 service lights to go b4 the next service.

Absolutely not, it's a timer. It comes on two years after it was reset. It is independent of the SI lights.
Most of the consumer reset tools don't reset it. Not sure if there is a sneaky way of shorting two pins together to reset it though.

I also want to know how to reset it - cant do it with Carsoft, Draper tool or the sneaky wire shorting trick.....it seems to be dealer only. rrrr

There is indeed a "short" way using a bit of wire in the diagnostic portRobert T wrote:Not sure if there is a sneaky way of shorting two pins together to reset it though.
IIRC it was pins 7 and 12 for 2 seconds - but don't quote me!
I'll post link if I can find one.

Re: Replace brake fluid warning.
Sorry but mine was changed by BMW in 2004, and then by myself in 2007 (but no light on), and now three years later....still no lightRobert T wrote:oakley6691 wrote:Others may be able to confirm, but i'm pretty sure the brake fluid light comes on when the water content in the fluid reaches a certain limit, when you bleed the system through with new brake fluid the light will go out on it's own, easy job with an easy bleeder

It's just possible that the warning light "bulb" may have failed.......
Sounds like a teacher telling a pupil of
And then before you use your car again make sure it has some nice fresh, dry brake fluid - please
Apologies Oakley - no offence intended - another example of the reading being different from the implied written word.
On a serious note, I wonder if there is a way to to "test" the warning light since it appears not to have worked for at lest 4 years.
It should be a simple 2 year countdown.

Clock
Yes - the clock symbol is operated by a simple timer two years after being reset. Sensing moisture in the brake fluid - you must be joking!
The SI reset is controlled by the data link socket, which is alongside the engine, with a circular screw-on cap. Removal of the cap sets the system into 'Service' mode.
The clock cannot be reset without also resetting the SI lights, as it takes about 11 seconds of joining the contacts of the data link socket, whereas the SI lights only require about 8 seconds of joining the same contacts. (I forget the exact periods, but you get the idea)
Don't take any notice of the SI lights anyway - you are better off changing the engine oil every 8 to 10,000 miles, and resetting the lights a bit after the second light goes out.
After this the performance deteriorates, and fuel consumption goes up - I bet the SI circuit sends a signal down the data bus to the engine ECU, telling it to begin retarding the ignition a few degrees every thousand miles. This means that after paying maybe £400 for a fancy oil change, the car goes a lot better, and the owner thinks that it was money well spent!
I once ran mine until the orange 'Service NOW' light was on, when the engine was really sluggish and struggled to make 30 mpg. I then reset the SI lights, and it was like having a new car!
To reset the SI system, get a piece of wire which fits firmly into the sockets of the data link connector under the bonnet. Now turn the ignition on, insert the wire into the sockets which are in line with the 'beak' of the hole at the centre of the connector, on the outer edge - pins 1 and 7.
After the appropriate time has passed, pull the wire out, and turn off the ignition. When you turn it on again, all 5 lights should be on, and also the clock symbol extinguished.

Re: Clock
No i wasn't joking because when i'm joking i want people to laugh at what i say and it's already been made perfectly clear i was wrong.....so cheers for keeping onMike Fishwick wrote: Sensing moisture in the brake fluid - you must be joking!
Does this help, says for oil but as there's only two holes it might be a case of holding it longer (see text)

OK, now you’re ready to reset the oil service light, so turn the ignition key to position II, but don’t start the car. Get out of the car and go to the data port. Always connect pin 7 first. Once you’ve inserted one end into pin 7, insert the other end into pin 19 and hold it there for 4 seconds. Then remove the paperclip. Check the dash and the oil inspection lights should be reset. The reset occurs upon removal of the clip.

I must be missing something here. I've read that link several times and it appears to me that connecting of pins 7 & 19 only resets the service lights (the green, amber and red squares) and nothing specifically refers to the brake fluid clock reset.
Is your reset device from Bavarian Dominator the one with three buttons where the yellow one resets the brake fluid light?

If you just want to reset just the service lights you remove the link after 4 or 5 seconds if you want to reset the brake fluid light you leave the 2 pins connected for longer, i think you`ll find using this system you can only reset the service lights & the clock symbol
Incidentally my reset tool is the 2 button version, my zed`s a 99.
Hope this helps, regards Gary
