Bad wastegate actuator?
As anyone ever had a WG actuator fail? I'm having huge boost spikes (hitting fuel cut) with my TD04 and have tested or replaced pretty much every control component including the boost map itself. My actuator seems hard to move by hand, the flap is moving freely though.
Any thoughts?

My spring/arm seems hard to pull out and sounds dry or rusty. I'll remove the actuator and bench test it with the air compressor. I assume it's a standard 0.5bar/7psi actuator, should it be fully extended at 7psi or just starting to move?

To be honest, is so easy to make, I did it myself, just welded on a v band flange to a japspeed up pipe which the wastegate went on to, welded the turbo internal wastgate shut and its done tial 38mm wastegate was only thing I had to buy at approx £200 which is worth it in my opinion... Future proof too.

Haha! Nice!
Yeah some photos or something might be of help. I have a MIG at home and have already welded bosses and so on to my exhaust for wideband and EGT sensors so welding a section of pipe in shouldn't be any hassle for me.

I actually tested it earlier. Starts to move at 6psi and is fully extended at 13psi and appears to work pretty normally. I don't have another one to compare it to though.
