I bought a used Brera 3.2 V6 two weeks ago (from an Alfa Romeo dealership) with 98000Km on the clock with full service history (oil temp sensor not working which they will replace as soon as the part arrives). I believe it is a 10 hour job.
Previous owner had apparently driven the car on a dirt road as he lived outside of the city.
Must mention that the car had a full valet before I took possession of it. The engine was also washed with high pressure jet hose,etc.
While filling in the forms etc, my son was with the sales person and the workshop manager as the car would apparently not start.
They had then also apparently put the diagnostic computer on which showed no errors.
Well I got in and drove it away unaware of what had taken place while I was signing the finance forms (until my son told me a week later).
The first week I drove it accelerating in the slip lane onto the freeway at 100Km/h in 5th gear and it started spluttering and jerking.
Took my foot off the accelerator and it stopped spluttering. Changed gears and drove normally up to 120Km/h and then accelerated again in sixth gear and it spluttered again, took my foot off and it went normal again. Drove home and while in 3rd gear at 3500 RPM it did it again, take your foot off and it's fine.
The car went fine for a week until I returned from a 60Km trip on the freeway it suddenly cut out and spluttered as if on one cylinder and I could not get the engine to rev over 500 RPM. All kinds of lights came on and eventually the engine died. Tried a few times to start it and then it suddenly went as if nothing happened. A few Km's down the road it did it again and then another few Km's along the road once again. I drove it in first gear putt, putting along by what sounded and felt like one cylinder at about 5 Km/h till it died completely.
Managed to start it eventually and drove the last 1/2 Km home in perfect order, engine revving at 5000 RPM without a problem.
The fuel was between 1/2 and 1/4 but my trip counter said "Trip distance exceeded" and also "vehicle break-in detected"
I called the Alfa garage and they came and towed it to the workshop.
They called two days later saying the diagnostic computer did not detect anything wrong.
They said the coils were fine and they were going to still check the pressure from the fuel pump.
They had driven it up and down and also had it idling in the workshop and no cut out of the engine at all.
Surely there must be something wrong somewhere which the computer diagnostics does not show.
How can I be sure this won't happen again? Help anyone !
