Well that will teach me to read and not just look at your sig pic! In that case you should have measured the pads and entered the thickness when you changed them +++

Could be you are within a tolerance, but probably worth running the adaption when you get vcds!

Thanks I'll check to see when it arrives

The D3 definitely needs to know pad thickness as it uses that to calculate when the pads are worn down and hence control the light. If you change the pads without telling it the thickness of the new ones one of two things happens:

1, it still thinks it has old, worn pads and puts the warning light on before the new pads need it

2, it has no idea what pads it has so doesn't both with the warning light at all. The first sign you get of worn pads is it wearing through to the metal and destroying the discs! That is assuming, of course, that you rely on the warnings to tell you when the pads are worn.

It uses the servo in the motor to determine how much the piston moves by when it applies or releases the parking brake, but it doesn't know the absolute position of the piston, hence why you have to tell it the pad thickness so it can calculate the change from the piston movement.

Is this a sign for the future?
Mikki knows something about D3's
Is there hope for the lesser ones amongst us?
If I don't fall of my perch could it be that my D4 could feel the touch of her gentle hands?

I know many things about D3s. These things are exactly why I only work on D2s :ROFL:

Well, that put you straight Ray ! :ROFL:

I am pleading Old Age, I didn't mean it Guv.
It was the Leprechauns that made me do it, honest.


My D4 passed it's MOT today. It had been delayed by 6 months due to Corona.
It came up with 14 days to oil change so that was done at the same time with a new filter. I can't complain, cost me £100. Parts only, no labour cost.
I am so lucky, the way I am looked after.

Ah, the "Big boys made me do it and then ran away" excuse.... or in your even less credible case, the small boys.:tuttut:

Good to hear you got the MoT though, Ray +++
