Love your work scotty love to be a moderator but I am only a diy mechanic.
Also love the car u call steaming pile of junk, Bmw, audi and porsche lol
But love to do my own work on them.
Question I have a problem with my brake on an audi tt 2000. The brake fluid was bleed and it bleed dry.
Currently I have an issue - the pedal is hard when the engine is off .. but goes soft when the engine is turned on ...
Best way to reflush the car to get the pedal hard again when the engine is on?
Love your work.
Fix it
This is how i fixed it ..
I needed a pressure brake bleeding to push the air out of th system.
Scotty showed a video of going pushing it from caliper up I have the one pushing reservoir down. (Fit on the cap)
Pump up the system to 1 unit maximum.
Three bleed points other the caliper.
Clutch and two just below the reservoir.
Bleed this out first (it will be messy so have towel and gloves)
Then bleed from the caliper close the abs unit from front to rear getting rid of all the air.
I give it feel pump on the brake while each caliper is open and if u have friend ask them to watch for air coming out.
Ok once this done test brake pedal.
All was good .. silly money pit cars but i love them
the pedal is supposed to be softer when the engine is running.
If the braking is bad then there might still be air in the system. I don't know what kind of work you did on it, bit the air can get trapped in the ABS system. If not that, then the rubber flex lines could be worn out.
