DIY boost leak fix

[h100vw]

Gav what's APR's valet boost level again? Do you think valet mode could have been accidently activated? Just thinking 3 to 4 psi is even too low for a boost leak??

Not sure you could turn it down that far? Worth checking though.

Only the one APR program loaded, no valet setting here.

Would setting the tune back to standard reset anything of sorts?

I assum the N75, like anything else, can fail.

If it failed, it would be open and you would get 6PSI so that doesn't work for me. A scan would be a really good idea. I'd expect that cycling the ignition, would clear anything that going to the std tune would do.

Any other VWs in the Rally that might have a scanner?

Wastegate rod still attached and tight.

All engine bay plumbing appears to be ok, looks like it'll be a long day of searching!

Well, removed, cleaned, checked all plumbing from turbo to throttle body.

Found one hose had come awry on the steel turbo charge pipe behind the engine cover. Left the battery of while checking everything else, put it back together and we have boost again...

Was that the big diameter pipe to the diverter valve.

No, little one to the right.

Maybe

I'd had enough by the end of yesterday, someone else can have a go now with a fresh set of eyes.

The exhaust flange has never faulted before, but at this point in time nothing would surprise me.

Thanks for all your help guys!

The turbo bolts you can feel from above, I've not had any issues with them since I last replaced and used a metal repair material to keep them in.

Car has to be cold, so much heat from the turbo even if its just been idling.

Hoyhoy.

If it is loose turbo bolts it would sound like a tractor, so I would say that idea is out.

Fixed - was the join from the hard line to the silicon hose up to the throttle body. Seems mostly OK now, but certainly not the car I had two weeks ago.

Boost used to peak 19psi, settle around 17 or so - Now it'll peak at 15 and hold maybe 14?

Man, I need to get educated about these things. Considering the N249 and SAI delete.


Now that we've got a sensible for the girlfriends daily , I'm getting serious about planning a turbo upgrade/exhaust/gearbox/diff/cage and entering some big stuff.

Hoyhoy.

Sounds like Stu's getting the disease, poor bugger.

Always had it. This is the car which has remained mostly standard for the longest time. Always had hot cars

Living in a pertol-headed, circuit-racing family is no help when you're desperately trying to save for a house. Then I go to work at ARB and watch people throw $18k+ at their cars. Gives me the itch!!
