Any help would be appreciated, I am getting a Warning code popping up usually when backing off after boost and braking the error code is Brake fluid level now the weird thing is i have checked the brake fluid level and its full (could it possibly be too full?). on a side note the brakes shutter a bit when braking hard as well. i was unsure where to post this as i could go a few different topics. cheers

I tried to overfill as I am getting this error but it was just getting progressively worse. Took it to the local brake guys. They drilled a little hole in the pipe in the cap where the sensor pipe sits to drain captive fluid. Now its much less frequent but still happens.
I have emailed Neil to see if he has replacement filler caps in stock. In case he doesn't, does any one have a functional second hand one?

Adam, I believe it was the dirty old, full of moisture brake fluid that entered the tube and caused the fault. If that same fluid is still in the reservoir it will again enter the tube and do the same. If the brake fluid is new and the sensor tube cleared of brake fluid then you should be ok but remember to clean out those tubes every time you change your brake fluid and you won't have any trouble from false level alarms.

Dave, I'm still of two minds as to whether or not there should be fluid inside the plastic tube at all. To me it looks like once it is assembled heat and light pressure was used to deform the tip and press the plastic surfaces tightly together. The float on the outside of the tube exerts magnetic influence/force on the switch inside the glass portion of the probe and completes the circuit triggering the warning and therefore there is no need for fluid to be inside the plastic tube. I have a spare used sensor so I’m thinking if I can’t get either fixed I might use a soldering iron to seal the bottom of the tube on one and test my hypothesis.

No, there shouldn't be fluid inside the tube at all. The tube should be sealed, and the o ring at the top where it attaches to the cap should seal the top of it.
Not sure about the old crap fluid theory, I'd suspect that it's only 99.9% fluid tight and over the last 15-20 years a very minute amount has worked its way in each time the car was driven.

You both could be right but fluid has got in once so it will get in again; when I don't know. This business of topping up the level to fix the problem is not the way to go for this type of sensor.
