Hi help please -
I bought my 159 2.4 JTDm 6 months ago. 57 plate.
It has 70 k on the clock. Recently it's starting juddering at very low revs pulling away gently.
This cleared if I put my foot down. As it's an semi auto box I can't dip the clutch as on a manual. It feels like a misfiring spark plug .
I have been back to the garage I bought it from (Mazda and Subaru) specialist and they re set the diagnosis.
It's now picking up an alarming shuddering at cruise . 70mph at 6th gear and the car judders and won't accelerate. Turbo needle seems to be bouncing up and down.
I dropped I to 5th and the same applied , 4th and hard foot down and it cleared.
It's now becoming a regular event - I have read various peoples views.
Use better diesal , use an additive, Epg block off .
I have been back to the garage 5x with this car in 6 months - I still have 6 months full warranty left but feel reluctant not going to an alfa garage .
Any help would be appreciated. I have lost confidence in the effectiveness of overtaking if the car is going to die and lose power without notice ...
