It's the same engine that's in my Vectra (Z19DTH (150ps)), not sure what the 140ps version is, but the 115ps version is actually the 120ps in the Vec (Z19DT(120ps) which is only 8 valve, so no swirl flaps. Personally I haven't had great experience with it at all....but I know I tend to pull the short straw when it comes to cars lol.
Anyway, the EGR is stuck wide open on mine, put the half arsed blanking plate with holes in - it did nothing at all so have put a full blank in but that leaves an emmsisions light on on the Vec, may not on the Alfa. Can be mapped out fairly easily but obviously remaps cost money, haven't been able to find a cheap one like I can with certain other engines.
Turbo's whine like a bugger on all of them, so I assume that's not a fault but just annoying as sounds broken lol.
Swirl flap manifolds again are a common fault - usually because of the EGR valve sticking open and clogging the mani and jamming/breaking the flaps. Mine haven't completely broken yet, but are stiff to move and the bar that joins them is loose, only a matter of weeks before that's completely f*cked. There are some cheap bodges for this like gluing the flaps in one place, though Im not sure how good that is in reality.
There is no DPF on the manual Vectras with this engine, so I'd assume the Alfa won't have one either as it cant be any heavier.
Does have a DMF which is shit, the one on mine was replaced at 75k and isn't smooth or quiet despite only having done 30k since.
Thermostats are also a common item to fail, not sure if they're the same across the board but I guess it would be, and as it's the housing and sensors all in one lump it costs £70 for a genuine one!
Also the oil filter is in a stupid place....and pee's oil all over the exhaust when you remove it, so that smells nice for a day or two.
Only other common fault is the same with most turbo engines these days and that's split vac hoses, which cause huge boost lag but are easy to replace.
Oh and the injectors wiring, specifically the third injector plug can break down and cause a misfire, which there is a dealer fix for.
So that's my opinion on the engine lol....but as for the car, the Alfa 156 looks awesome imo, in dark grey as well, mmmmmmm.
