Hi, firstly I am new to this forum, and have read already a few threads, and can see you guys love Alfa's and a lot of you are knowledgeable. I owned a 156 2.4JTD a while ago, enjoyed it. I just bought (Friday 20th April) a 2007 Brera 2.4 jtdm, and it has broken down Sunday morning. I am positive some Alfa genius will point me in the right direction.
I am very mechanically minded, and capable of this type of problem solving (I run a business that restores classic cars (SouthCoastMustangs.com - Classic Mustang Specialist
)), but I don't have any experience with modern diesel engines.
Here are my story, symptoms, Brera-life-story in order...
The car sounded a bit rough when idling, but it is diesel and I haven't heard another Brera or similar to compare.
There is very poor low end power - from 0 to 10mph it is very sluggish, until the turbo kicks in. I understand that it is normal for a surge of power when the turbo catches up, but the lack of performance at low revs was very surprising. A smart car out accelerated me. The same is the case at low revs in 2nd, 3rd, etc.
There is 0 pressure on the turbo gauge at idle.
Upon starting it on Saturday, it stalled (I wasn't moving at the time, so it's not my clutch control). No big deal I thought. So I started again, it ran a bit rough, I brought up the revs immediately, and it seemed to cure. I drove, and it was fine.
Upon starting it on Sunday, showing a friend the car, it turned over a few times, fired up, but a lot of smoke came from the exhaust and it sounded rough. Like a van, not an Italian car. I brought up the revs and it cleared, and went on my journey which was fine.
I picked up another friend (a girl, who may have been impressed). On the motorway I started to lose power, I was in 5th in cruise, at about 50 or 60mph, and it started to lose speed. so, I dropped a gear and accelerated. Not long after, I came off the motorway, and a warning came on the dash:
"insufficient engine oil pressure" or "insufficient oil pressure" - I am wording it both ways for google to find this thread for other uses to search.
I pulled over, and typed that into google - I realise it's Italian and therefore probably an electronic fault, not an oil pump issue. A lot of threads pointed to the EGR, so I moved the car and got it home.
I read a bit more about the EGR, and quickly took it off to inspect and clean it.
The square port of the EGR was caked in soot / carbon - the intake side almost appears blocked. I cleaned the EGR, but the valve and assembly moved freely, but I could not tell if the valve was closing correctly or not. I re-installed it back on the car, after scraping out the carbon from the intake side.
Started the car, and it ran exactly the same. So I thought to drive it a few metres, and it stalled / shut down again. I got it a bit further, then a load of warning lights came on the dash "hill hold not available, "ABS not available", and many other ones that I didn't have time to read.
I pulled the key out, locked, unlocked, put the key in and attempted to start it. It barely turned over, and had more warning lights. I thought "battery??". Then, it turned over a little more normally, and started up...coughing a bit before firing, and I got it back to the driveway.
There was no power, pull or acceleration at all at that stage, and in the drive is where it is now. I attempted to turn it over this morning, before going to work to pick up a '66 Mustang I can use daily, but it turned over and over (slowly... battery?), and did not fire up. It coughed, thought about firing, but didn't want to do it.
During the drive that I had, I went normal speed limits, and got it up to 80+ on the motorway, so it hasn't been switched on and off and choked up.
Your thoughts please...
