hi ya i own a multipla 2005 1.9 jtd started being slugish 7 months ago did not think much about it untill it went into limp mode with no lights on dash showing any faults. took to local garage where we checked the egr valve, turbo.
to put a long story short the turbo had fallen apart so had to be replaced fiat garages quoted between £1000-£1500 got a brand new turbo from CATS AND CARBS you can find them online cost me less than £500 with delivery.
i would tho recomend u get ur injectors tested to as when the turbo was fitted the car was not firing on all 4 cylinders
now paid for 2 new fuel injectors at a cost of £200 half price of what fiat wanted to charge.
multiplas are very expensive to fix ;(
