Turbo issues, 159 ti 2.4 jtdm wagon. VIC

[NewtoAlfa159]

So as my Christmas present and thanks to the wife working 2 jobs and me working 3. I've finished paying off my mechanic the $10,000 worth of work he did to my 159.

But my mechanic isn't a specialist in turbos, and despite me saying to him that it's got a vacuum leak they've driven it, hooked it up and done their version of testing to no result.

But I can hear the damn thing. It's a 2.4 jtdm ti black wagon that just ticked over 120,000 ks. It runs beautifully but I think it just needs maintenance that I don't have time to do myself otherwise I would.

Does anyone know someone who'd actually know what they're doing and be able to diagnose where my turbo leak is coming from? It also has a couple other issues which I think aren't helping, which is the throttle body needs a clean, as does the EGR.

Can anyone recommend someone?
Pretty please? Hopefully someone who won't make me wait until the end of January, I need the car as I work three jobs and I feel if I leave it to end of jan it might develop more problems.

Thanks in advance for any help.

Common problem with the 2.4L JTD engines is the Diesel Particulate Filter (DPF) soot build up, especially if driven in short low speed journeys. Refer to following link for Symptoms for bad DPF.

As you are located in Melbourne contact any of the Alfa specialist, refer to club sponsors list at the following link.

To help clear out the DPF somewhat, short story is it needs to be heated up to a certain temp where it starts burning the built up particulates. If it was blocked up enough then you will actually get a warning on the cluster with a symbol representing it. So if you haven't got that yet then your DPF probably isn't that blocked up.

However, there is something you can do yourself in the mean time which is probably just as good as taking it to a mechanic. Just to be clear, I actually had the DPF warning come up so I knew mine was pretty blocked up and when I did this method of treating it, the light went off when it was better.

Find a stretch of road where you can drive continuously with no stops and preferably no corners at around 50 to 60kmh in 2nd gear which is around 3000rpm and do that for about 15 mins.

Due to the continuous high revs, this will heat up your DPF to the high range necessary to start burning off particulates. In my case after about 15mins of driving in that way, the car finally jolted a bit at the moment that the light went out. At that point I knew it had done enough.

About your turbo leak, if the mechanics have tested it and say there is no leak, why are you so certain there is one? Do you know what a waste gate sounds like? Maybe this is what you're hearing.

You say you can hear it but what exactly are you hearing and when?

I'll also ask, what makes you think you have issues with these items? Could you give us the symptoms?

Also, who is your current mechanic/specialist?
