Hey everyone, here's a puzzle:
So the turbo on my d40 blew up. Replaced it with a Japanese ebay turbo and works great. However before I pulled the original turbo out I gave the engine bay a wash and unfortunately water got into the brake reservoir and destroyed the master cylinder so had to replace that.
Before now, it was realised that applying the pedal actuates the waste gate vacuum on the turbo. So today I replaced the vacuum tubing connected to the turbo.
Now the problem follows that when the car is turned off and you apply pressure to the brake it behaves like every other car turned off and builds up pressure. When the car is turned on the pressure disappears and the pedal descends to the floor.
Prior to today, before I replaced the vacuum hose. The brakes worked but would lose vacuum if pressed repeatedly before stopping. Now after replacing the vacuum hoses the brake still hold pressure when the car is off but now when on, the brake pressure disappears until the pedal touches the floor, brake barely working.
The brakes have been bled to infinity and the turbo valve solenoid (14956u-eb70b) was tested following this video: and appears to work.
We have a advanced obd2 reader that can run individual systems in the car and in an attempt to bleed the abs pump, the pump runs and then a prompt appears saying that, that function is not supported
We are at a loss with the only feasible idea being that a vacuum is being created in excess. Any advice would be greatly appreciated! Thank you
