Another stupid error i made was to only drive the 1 159 which is the 1 i bought so i need some stupid reassurances from you.
1.Driving i traffic i can feel the engine engage the clutch. Its not a clunk i can just feel the transition, is that ok?
2.I noticed a little puff of white smoke/vapor from the exhaust when i started up from cold, is that ok?
I know i should have tested alot more 159's to get a feel for the car, but i wasn't able. stupid me!!
car is 159 JTDM 1.9 lusso 16v, 08 plate 109000 miles, full service history, cambelt changed 77000, last service 103000, mot done last week.
Your views and most probably opinions on my stupidity will be appreciated.
By the way when driven hard the car is awesome, i just want to get the traffic jam side of it sorted.
Welcome to the world of Alfa 159 ownership - and Alfa ownership in general if this is your first.
Taking your points in turn.....
1. There is a general rule of thumb you should remember, which goes as follows:
... lack of power below ~2500rpm means EGR issue, lack of power above ~2500rpm means MAF issue.
As a general rule of thumb this works.
The best way to try and rule out the MAF would be to unplug it and go for a drive and see if the car responds better. It will give an engine management light with it unplugged but don't worry too much about that, that will go away again after a few engine starts (assuming you plug it back in).
2. Clutch engagement.... are you running a manual or auto box? Be aware of issues / funny noises and slack nobs in 5th and 6th gear on the manuals. I don't think you've got too much of an issue there though, long as you're not suffering anything like vibrations or juddering.
3. Smoke on start = normal. Seems some of them do it, some of them don't. My 1.9 JTDM is in the does it camp. It would seem that the crank case ventilation system pumps a lot of oil vapour back around the engine. My theory is that when left to sit and cool, this oil vapour condenses and ends up being fed into the cylinders on start. So long as this disappears after a couple of seconds you're golden.
Keep an eye on the cambelt change regime. it is well respected law that you don't push your luck with the Alfa cambelts.
According to the service manual you should change the belt at least every 5 years, regardless of mileage, or every 4 years for heavy use, meaning a lot of around town driving or in cold climates.
Judging my 109k miles on the clock it hasn't been an around town car so you don't need to worry about that, just ensure it is changed around 5 years for safety's sake.
Also be aware of oil change requirements - the car has an oil degradation calculator built in. When diesel cars run a DPF filter regeneration it is well known that diesel fuel can make its way into the crank and therefore get into the oil. Too much of this occurring will mean you need to change your oil - which the car will tell you. Just don't write it off as "oh, I only did that 6 months ago, why am I doing it again, stupid car". If she tells you to change the oil, change it.
Sounds all big scary stuff but forums are full of people trying to fix problems, so don't read too much into it!
