Dear Alfa Lovers,
I bought a 57 Alfa 159 2.4 Lusso last year and up to now I have been extremely unlucky with this car.
I had a full list of problems including failure of ABS pump shortly after I bought it, power steering failure, cold start problems, etc.
Over the last 4 weeks I developed a DPF fault (already had a forced regen a few months before) which did not respond to the normal regeneration. I decided to try cleaning the DPF using TerraClean - it showed a drastic reduction in the pressure difference between the exhaust areas before and after the DPF, which suggested that the filter was cleaned. However, it was not possible to do a forced regen and I therefore drove the car at high revs for 50-60 miles.
Whilst doing the above I noticed vibrations in the front of car and a few days later my car went into limp mode again and smoke was coming from underneath the car (I suspected the DPF filter). The strange thing is that the smoke was coming out when the engine was OFF and only after a short distance of driving.
I got the car on the platform to my local garage and in the end it needed replacing both the clutch and the dual mass flywheel.
After I took the car back I noticed that there were still some vibrations/ miss firings present (though the clutch sleeping and dual mass flywheel symptoms disapeared). In the end the engine light went on and the car went again in the limp mode.
The car was taken back to the garage on a ramp and this time the lights indicated a problem with the injectors. They took out all the injectors and serviced two of them, as they had problems when revving. When they put the injectors back they was also spotted that the common rail pipe was leaking and they replaced it.
Once they re-assembled everything back, another DPF error appeared. They took down the DPF filter and to their surprise (and mine) the middle inner section of it was MELTED!
They fitted a new DPF, started driving the car, and after 5 meters - BOOM! A braking noise was heard and a cloud of smoke, to both my despair and my mechanic's!
They suspected that something more sinister has happened and took the TURBO down - they explained to me it has basically snapped in two pieces and they would advise me that engine needs stripping down at a SPECIALIST GARAGE, as parts of the turbo may have went into the engine (and therefore replacing the TURBO may be futile and increase the overall costs, without making sure that the engine is right).
They also think that my car may have had some symptomatic problems that led to the current ones, especially speaking of the DPF - they were saying it's NOT normal for the DPF to melt.
I suppose that by now you can understand my frustration with this car.
TBH it could've been even worse, as part of my expenses up to now were covered by WarrantyWise.
So, if you did bear to read the above, I was hoping that you could give me some views of what the problem may be and what would you do in my place. The warranty should cover the repairs as there clearly was a mechanical failure of the TURBO.
The car is on finance as I couldn't afford a newer car (lesson to be learnt). In an extreme situation I may need to scrap it, but on the other hand I replaced a lot of the other bits already so I would rather try to sort it so that it wouldn't hopefully brake anytime soon.
As a side note, I completely trust my mechanics - is a well respected local garage that I have been using for years. They are honest people and sometimes helped me at their expense (like fitting things for free as).
Please help me with some thoughts/ advice!
