159 fuel consumption
I have just joined the forum so apologies if I have missed previous threads. I though I had posted a reply but it appears to have been bounced so I will try again. If it appears as a duplicate it is operator error.
I haven't visited car forms for any previous cars but the 159 has changed that. I have just bought a 170 jtdm Ti Sportwagon with 4K on the clock. Having read about tyre wear issues I had these checked before buying an knew there was an issue with this one, but thought that it could be sorted out with correct alignment. Having had the car a week I realise there is more going on here. I have had two 156s, a 1.8TS saloon and a jtd sportagon. The saloon scrubbed the fronts, the diesel didn't. The petrol did 28 to 31mpg, the diesel 45-55mpg.
I then moved to a Saab 9-3 as I was too tight for a 159. It had the 1.9jtdm Alfa engine with a Saab/GM map. The car was good returning 40-50mpg before fitting a module when it went to 44 - 52 mpg set to its maximum performance setting and a big boost to performance. As I always felt the Saabs handling to be loose I was drawn back to the Alfa 159.
After aligning the wheels the handling livened up a little but still feels insecure at the front. I did 800 miles on Sunday/Monday and it retuned 35.5mpg, rarey exceeding 80 as it was a bit snowy. the Saab was driven faster and would have been hitting 50 on the same run, and would have been driven harder as it was much quieter.
What is going on here? Is it rolling resistance, engine or both? The Saab wore 215 tyres compared to 235 so not much difference. The weight and dimensions are virtually the same. I don't think it is wind resistance as the trip shows bad fuel consumption at all speeds, not just when you hit the wall at about 80. Why do they vary so much?
My previous experience with Alfas are mixed. The 1.8TS was never right and after 2 years of complaining to the main dealer and being assured it was correct, I took it to a specialist who eventually found both cams to be one tooth out despite a cam belt change. Set correctly the car was great except for water around the plugs which was cured by removing the seals. the jtd was bought as a stop gap measure on ebay and was great and did 85K over 3 years with only a blown turbo hose.
So back to the Ti, while driving it yesterday I was trying to put my finger on what it felt like, I finally got it - it felt like a van. So with that out the way, do I persevere with what I think is a bad car, or cut my losses? Do you fix a bad 159, or does it just get less bad? My worry is that if I part with this one, it will be my last Alfa.
