Hi guys just an update

Came back from the workshop and he said that it was likely the actuator on the turbo that is stuffed overboosting the turbo causing it to whistle.

I advised him at first that it maybe the gasket between the manifold and Turbo so he opened the bonnet and reved it. He said if it was a leak he would have heard it.

So we then went for a spin and at times the boost would spike to around 13-14 psi and make that whistling noise. When the boost only when to 10 psi it wouldnt.

So his diagnosis was that since he had removed the boost controller and put the stock bits in and it was overboosting that it is probably the actuator that is stuffed causing the turbo to overboost and make that noise.

Opinions please? Sounds plausible? Should I get another workshop to look at it before I decide to shell out for a new turbo.'as he said I just may as well buy a new turbo.

Any help much appreciated :)

I would say hes probably telling you the truth. I've unfortunately got an exhaust leak from my rear turbo and the sound doesn't come or go, it's always there. You can hear the 'airy' sound on decel and it runs like a bucket of shit. Have him finish of his work and before you pay the bill ask him to come for a quick lap to see if it's still doing it.

I doubt you need a new turbo.. more like the actuator hasnt been put on properly or you have a leaking hose, why not get in there yourself and eliminate all these possible causes, source a second hand acutator and try it yourself

i leaking hose would give you overboost, cost to replace =zip

get a bright light in there and look for any soot gather around the gaskets which = leaking gasket

make sure you dont have some garrett highflow, i never knew myself until i was told,

you dont have a cheap split dump pipe do you?

Just an update guys!

So after 2 weeks of being told the noise is my boost controller, then my turbo , then my actuator and dismissing that it can't posssibly be the gasket between the turbo and manifold, I dropped off the car to Rob at Sabbiddin Automotive to get the car checked out. I've had my car for their for mechanical work in the past and respect his professionalism.

I just received a call from Rob just then and hey prestoooo...It's the gasket between the turbo and manifold, and that there's a bit of shoddy work from the previous work :rolleyes:

Regardless I'll be eventually getting a new turbo soon, but didn't appreciate the advice from the previous workshop even after telling him what was the problem.

So just a shout out to everyone that helped and especially Daniel from Elite Racing :cheers:

I won't publicly name the workshop as that isn't appropriate & allowed and to a certain extent everyone makes mistakes, but I will say this workshop is in the South-eastern suburbs of Melbourne and is a workshop referred onto by one of the top Tuners in Melbourne that is regarded on this forum.

:thanks: to the SAU Community :action-smiley-069:

Glad to help. It's good that you found someone to sort it out for you. I was going to suggest someone when you asked but thought again about it. I was absolutely certain it was going to be that gasket so it is a good thing you persisted with it or you end up like every other poor bastard around.....even poorer and still without a fixed car.

Rule #2 is: If it smells like shit, feels like shit and tastes like shit....it's most likely not going to be a cheese sandwich

Just picked up the car and it feels great again. Rob said some bolts were missing, some bolts not tight, hoses weren't in properly ahhh i just had to laugh.

Now its time to save up for some ID 1000 injectors and a Hypgear turbo :thumbsup:

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
