159 1.9 Diesel Problems

I have had a 159 Ti 19 Diesel for just over a year and I have had nothing but trouble with it. The main concern is the engine which at present sounds like a 200,000 mile taxi cab thats never had a service. It has had various sensors changed througout the year but the problems always return. At idle the car shakes, pulling away the car shakes and in traffic while crawling along the car shakes. Does anyone have any advice for me before I set fire to it?

Have you had it in the dealer for repair?

Yes it has been in and out of the dealer for this fault a couple of times. Initially it seems to be sorted but then the fault returns. I do over 100 miles every at motorway speed so their argument various sensors becoming choked over time doesn't seem to stack up to me. It's booked in on Monday next week for it's 42,000 mile as well as the rougness of the engine. I'm really hoping they can sort it as it's a beautiful car with every optional extra added (bar the sunroof), but it's being ruined by what seems to be a crappy engine.

Engine shouldn't be that rough - not by any means.

I also think there is a lot of flannel over sensors blocking up - I bet if you asked them to be specific about which sensors they would fluff their lines.

Is there the chance that the cams are misaligned throwing the timing out. Being a diesel its never going to run like a sewing machine but, if theres nothing detectable in the engine, maybe they should start looking for broken engine mounts? Not sure what part of the country you are in but it might be worth trying another dealer for a second opinion.

Where are you filling up ? Have you tried different types of diesel \ supplier. The only time my previous car ran badly ...figured out it was always when I got fuel ( was a petrol car ) at one particular garage...not sure what they were selling but made engine run like muck.

Yeah - throw petrol on it first!

On a serious note - I would try a friendly local independent Alfa specialist!!!! Sometimes stealers are not best place to go for finding faults! (as they will have to fix at own expense)

The suggestion would be to go to Alfa specialist - find out what the problem is and then take it back to the stealer with the specific problem already identified!!!!!!!

Good example of this on a motorbike (the problem was a bent gear selector fork) Whilst the dealer found nothing!!!! As soon as the bike was started up at the independent specialist - just by the noise, the fella was able to identify the issue!!!!

Give it a try!

I will see what the dealer says on Monday and then make a decision from there. If it wasn't a company car I would take it to an independent alfa specialist for sure but fleet companies will only use main dealers. Regarding the fuel, it only ever gets the good stuff BP Ultimate or Shell Ferrari duel. I have even tried adding Redex in to the mix but it doesn't really make any difference.

I have a 1.9 jtdM in my 159. This is no joke, today at a course I was on in Livingston, one of the guys remarked on how quiet and vibration free my engine was at tick over. I don't mean to rub salt in, but it goes to show there is defo something wrong with your car. Am I right in saying there was issues on earlier cars with one of the engine mounts? Not sure how old your 159 is like, but its a starting point.
