Hi all
I've had my 2001 156 JTS for a couple of fun years now, but I've had a few problems:
Within the first few months it started complaining about one of the lambda sensors, and we had it replaced under warranty.
The problem came up again a few months later, but I haven't tried to fix it again (at that stage, the mechanic suspected we might need to replace the cat, but I didn't want to fork out the money for this, and it's theoretically not a critical issue(?)).
About 3 months ago I got some cylinder 3 misfires. I confirmed it was a coil pack problem by checking the resistance, and swapping the coil pack to a different cylinder. Replacing the coil pack fixed the misfire problem up until recently...
It currently has a rough idle, and yesterday gave me a triple beep warning. I limped home (jerky acceleration and crusing - felt like misfiring), and ran Alfadiag on it.
Among other problems, it's reporting cylinder misfires again, I pulled out the coil packs, but I couldn't find a problem with the resistances.
Having read some of the other reports in this forum, I took it for a quick drive while Alfadiag monitored the battery voltage - it didn't seem to dip at any stage.
Having read about *a lot* of expensive fishing expeditions, I thought I would ask here before taking it to a mechanic. Any ideas?
Alfadiag is reporting the following codes:
