Tubofords New Member 14 Member For: 5y 3m 1d Posted 20/08/22 01:22 AM Share Posted 20/08/22 01:22 AM I'm having the overboost problem (and going into limp mode) and am trying to diagnose. I have tried to manually move the wategate lever but it only moves about 10mm. (Trying to move it by pulling it with a hook) How much movement is there on the arm usually?

Tubofords New Member 14 Member For: 5y 3m 1d Posted 20/08/22 02:53 AM Author Share Posted 20/08/22 02:53 AM Thanks, I'll test it with 7psi of air. Hopefully it's just a leaky hose. If it's the actuator leaking, do you have to remove the turbo to replace the actuator? Link to comment Share on other sites More sharing options...

I took a video and it moves only about 5mm. Is this right? Link to comment Share on other sites More sharing options...

I don't know how much pressure it needs to rupture the diaphragm but it's not something you want to find out on your own car. The amount yours is moving is nowhere near enough. Either something is physically stopping it from moving, or the actuator is farked. Apply a small amount of air to the actuator via a rubber hose so there is no leak in the air feed. If you can hear air hissing from the actuator, it's farked. Link to comment Share on other sites More sharing options...
Tubofords New Member 14 Member For: 5y 3m 1d Posted 25/11/22 09:09 AM Author Share Posted 25/11/22 09:09 AM (edited) 😂 yeah I just kept dialling up the pressure till something moved, but I just had the air spray nozzle jammed in the inlet pipe. (and yes the car is 100% stock) I tried pulling the lever back more with a hook, but it would only move the amount in the video. So I guess I also need to now work out if the actuator is stuck or the actual wastegate. Edited 25/11/22 09:15 AM by Tubofords Link to comment Share on other sites More sharing options...
