Blown Turbo in my 04

Don't get me wrong, when I hit the right place on the accelerator the car shifts along no problem but I have never had to push down so much to accelerate, it is to me at least very noticeable. I'll give it a few more days and see how things go. I understand that the cats are a sealed unit so couldn't exactly be cleaned through. I was told today by the garage that the car was quite smokey on friday and it wasn't acceptable to give back to me in that condition. After 120 miles drive on the motorway yesterday with plenty of foot down experiments with the turbo I can honestly say that it's hugely less smokey that it ever has been in the 3 years I've owned it.

You have to ask your mechanic those questions,especially if he updated ECU!

That black box is the vacuum reservoir and has 2 pipes.Not unknown for this to crack and loose vaccuum !Connect the 2 pipes together to bypass the reservoir just to test.If no different ,connect pipes to reservoir again.

The cat is a sealed unit but what I meant was if the mechanic checked if there any turbo parts blocking it ,as usually when the turbo breaks,the turbine falls down the downpipe and stops in the cat.

Hang on ,you said that the garage said the car was quite smokey on friday and it wasn't acceptable to give back to me in that condition.Well,they must have remapped it back and reduced the fuel and hence your lack of performance and smoke.Could also be they put a smaller turbo,like a 2056 off a pre-facelift 3.0D and then the injectors were over fuelling the car,so they had to drecrease the fuel amount debited!In anyway,this is very unprofessional and they should at least have let you see the car when finished the turbo replacement ,for you to see if the smoke was as before.On no account should they have messed about with ECU,without asking you first as this has nothing to do with the work you left the car with them for!

Ok, here is a bit more on this.

I took the car out this morning and tried the 'adaptive throttle reset' procedure. To be honest I'm not 100% sure if this works or not and have seen about 3 different techniques to do this but I used this.
Turn key to position 2, press accelerator pedal fully to floor and hold for 25 / 30 secs, then release pedal and start car and drive off.

It does seem better through the rev counter but hey, that could be just me. I tried manual and auto through the gearbox and am much happier (placebo or not, lol).

I noticed that when I got my car back the washer reservoir had been drained and refilled with plain water to the brim. My front windscreen washers didnt work so I fiddled about and got them going. I still dont have my headlanp washers working now and they definately did before taking it in as I use them a lot. This is being looked into now!!!

Then 20 minutes ago I thought I'd recheck the vacuum resrvoir like you said Powers1. I removed the left hand pipe from it yesterday (nearest the drivers side wing) and it had a good suction. I wondered where the 'other' pipe is as you said above and connect the two pipes together....I dont have the 'other pipe which fits to the other end of the reservoir. Now, I've checked RealOEM parts diagram and one end goes to the turbo pressure converter and the other end goes into some more piping which hides under the engine cover.

Will this have any effect on my turbo perfomrnace? I'm sure it must have some effect being a vacuum. Part No: 9 is missing!

I'm searching as to what this actually does.

Edit: I have looked under the bonnet again and have found that the pipe (no 9) in the diagram actually is there and it goes to the left hand side of the reservoir. I stuffed my hand down towards the turbo and felt around and have found the other pipe which comes off of pressure converter just dangling around. Which pipe goes to which side of the reservoir?

Whatever next?

Seems that with the pipe off you get hesitation and power loss. read this on a different forum. This explains all my problems with lack of power, more pedal pressing and then finally boost kicks in. I'm off to the garage to see what they have to say.

........and finally after taking the car back to the garage and getting them to stick the pipe back on to the vacuum reservoir all is FIXED. Now I have lots of power through the gears like it used to. Think the turbo spinning up is a bit louder too, could hardly hear it before even with the window down.

Thanks for all the reply's guys, much appreciated.

Sorry mate,I just seen your message now.You seemed to have figured it out yourself.2 PIPES must always be connected to the vaccum reservoir,which is why I asked you to join them together,to eliminate any vaccum leakage from it.Since you could only find one pipe,that made it obvious that the garage forgot to connect one pipe which goes to the turbo solenoid and now with this pipe connected (thanks to your findings) your car is now fine again .
Either pipe can be connected on either side of the vaccum reservoir but you will find that one is shorter than the other.
Had to be vaccum loss as I said or at worst ,they fitted a different turbo.
Now,the question is ,what did they do to stop the car from smoking so much?
I bet you they left that pipe off,on purpose?
Anyway,glad you got it sorted mate

I don't know how much smoke was coming out of the exhaust to be honest but there isn't any now. I'm just assuming it was simply the last bit of oil in the cats and pipe work etc. it's just nice to get back in the X

Glad you got it all sorted.
That smoke you are talking about is "white" smoke ,which as you said is due to the oil that found its way to exhaust system when turbo broke and has now almost cleared.
Hope all else is fine with car and the garage didnt forget "anything" else

Depending upon where you might be in the UK you could always look up BWChiptune to get Jason to have a look at the mapping etc. There's an active UK Forum too now (helped out by XOutpost. ) at Xdrivers dot co dot uk that will be able to help out with UK Spec cars if you get stuck too.

Thanks for the info. I was planning on selling the thing at the end of this month and this happened. Only thing I need to sort out now is the headlight washers. These don't work now after this little job (neither did the windscreen washer jets either but they are now). I have checked fuse 28 which I believe to be correct and that's fine. Can't hear the pump going though so that's a bad sign. Did try sticking a meter on the pump plug and with lights on and pressing the S button on the stalk got no voltage! It was dark though when I did this. Will continue investigation when I get a chance.

Hi im glad you got it sorted,
