DIY boost leak fix

[noone]

Sure its a leak?
If you're getting nothing I'd think the loose connection will be very obvious, a flashlight and some time poking around under and down behind the headlights / up through the foglight grills should give you a glimpse.

Check the actuator rod is still connected to the wastegate flap. Just read your first line again, no boost at all.

If you had a massive boost leak, I am sure it would stutter like mad, my S3 did when the elbow off the turbo split. As soon as you got to atmospheric pressure it fell over.

Well it still drives 'okaaaaaay' albeit with no grunt.

It picks up off the lights, gets to 1400 or whatever revs, builds 2-3psi, then pulls all boost back to vacuum again.

Very odd. I was under it yesterday but didn't notice anything glaringly obvious as far as loose/split plumbing goes.

Up on stands tomorrow and have a gander I guess :/

If you see any boost then the actuator is probably ok, unless the nuts have nearly wound right off? I am really thinking a decent split in a hose, that holds boost, then gives up.

Wastegate who in the where now? Turbo stuff confuses me greatly.

I can build a hot mini engine though!

Got a boost gauge in the cabin or access to something that can read a code mate?

I'm thinking disconnect the N75 and see if that changes anything boost wise first. How long were the stages? Also thinking sustained punishment could have sent something into safe mode.

Gauge, yes. Code reader plugger-inner, no.
