2nd Turbo just stopped working

Strange connection of pipes as Martiny said.

Is there a boost controller fitted?
Would capping off the two nipples restore boost to how it was before?  The top one is causing the hiss and must have been capped off, it normally goes to the wastegate actuator but another pipe is on there now, so deffo try capping that one off.  Not sure about the lower one.

Ok just had another look and I see there is an electronic boost controller fitted I think.

It\'s been plumbed in strangely, so as to control the dip/spike at transition with the boost controller.

If you want to keep boost the same as before, plug the open top nipple with a piece of vac pipe plugged at the end.
Then make sure the other nipple on the pre control actuator is connected to the solenoid, looks like the pipe is still there just needs pushing back on and securing.
(Having said that, I wonder if that nipple was capped off too, to stop the solenoid bleeding the pre control because the boost controller is now connected to it.)
I would try re-connecting it 1st and see if the boost controller is controlling the transition dip/spike, it should.
Hope you get that lol.

Ah-ha - we found the problem!!! It\'s on the pipe from the turbo to the intercooler. It seems that the claip has slipped somewhat and partially come out.

Yesterday we tightened it up and the boost came back. Hooray  Then it went again

Today i will be mostly........... pulling the whole part and relocating properly.

Yeah, good news mate - how embarised do I feel that we tok half it apart and didn\'t check that!!!  At least we found other stuff which will jst make it better!

Yeah, I pulled the hoses out at the weekend, and relocated them. Everything seems to have been slightly out of place as if it had moved over time. Everything now working nicely.

Cheers for all the help guys, i\'ll move onto fixing the other bits and pieces over the winter.... but i\'m sooooo glad to have my boost back. Scragged an M3 last night on way back from Stratford....hahahahahahaha i LOVE kicking Beamers!!!!

So can you now control the transition dip/spike with your boost controller? You should with that set up.

I wish my fd boosted to 7 bar

Hello - fellow rotary member here!  



The actuator problem sounds like it is the prime suspect except for the overboosting - 0-4,500 revs flip is getting 3.5bar and after its about 7bar.



Thanks guys :wave
