So no service pack with the car?
I think the brake fluid is done at year 3 and then every two years afterwards.

A hydroscope is a device, similar to a telescope built for observing things underwater

I have always wondered why brake fluid absorbs water, how in a sealed system it absorbs it, and would I want to pay BMW to do this when a local reputable garage can do it much cheaper and just as well.

Ouch!
Now I'm not suggesting you do this (I wouldn't with a car of your pedigree and age) but Halfords Autocentre are currently charging £37.
Maybe time to strike up a relationship with your local indy.

Brake fluid needs to be an incompressible fluid with high boiling point but inexpensive. Most (DOT 3, 4 & 5.1) are glycol based, with one (DOT 5) being silicon based. Glycol based fluids are, unfortunately, hygroscopic whilst silicon based fluid are not but the latter is more compressible. The problem with water absorbed by the hygroscopic fluids is two fold:
Firstly, the water reduces the boiling point of the fluid quite significantly which can lead to gas bubbles in the system and gas is very compressible so a spongy or long brake pedal can result under heavy use. Most brake master cylinder reservoirs are not air tight so air constantly circulates through the reservoir and the hygroscopic fluid continually 'sucks' moisture from it.
Secondly, the mositure content results in accelerated corrosion of the brake pipes and calipers from the inside out. As an example, my eldest lad's first car was acquired when it was some ten years old and the brakes needed a good overhaul. When bleeding the brakes after replacing discs, pads, shoes and all rubber seals the fluid that came out looked like evil pond water - it was almost black. It obviously had not been changed in its life and the effect of corrosion was clearly evident.
Also, only use the correct specification of brake fluid as defined for the system. Brake fluid itself can be very corrosive for rubber seals etc. and the system components are designed for the fluid used. Using a different spec fluid can lead to incompatibility with system components and failure of seals.
This is a very long winded way of saying that regular changing of the brake fluid is a good idea. For normal road use I would not recommend longer periods than every three years.

Should come away with gentle heat (low setting) from a hairdryer. You can specify de-badging when you buy a new vehicle. I know that Mercedes and Audi use the hairdryer method to de-badge cars.sad_old_man wrote: ↑Thu Jul 20, 2017 9:07 pmThanks for the help but what about the residual bits of adhesive tape stuck to the car?MJJamieson wrote: ↑Thu Jul 20, 2017 9:04 pm Brake fluid is hydroscopic and absorbs water so need changing every 2 year regardless of mileage, to remove the badge use tooth floss to slice through the adhesive backing.

I don't think the BMW warranty people like them - I seem to remember they had a clause in the agreement which didn't allow independents ?

and if you prefer not to do it at high speed, just graze a rim, walk back and see a ding is now in your door since parking, or gently bump into back end of a truck or wave to your wife as she drives off in it shopping.

3. Please tell me how to remove the smile from my face which mysteriously appears every time I drive my Z4?
It's oh so easy to push on in the 35is and be lulled into three figures !

I nudged the garage door the other day after ignoring the beeps and grazed the front spoiler in two places - not badly - but bad enough !

£118 for a brake fluid change??????? In my humble garage, its about 30 to 40 quid. Depending on time taken.
Gonna put my prices up...lol!!

Can't understand why the reservoir for brake fluid is not air tight like motorcycle system.
Where a small rubber diaphragm allows for the fall in fluid as pads wear.
