Revisiting this with an update on mine. 180 bhp diesel. Stop start ceased to work about 8 months ago. Didn't notice for a while as other half uses it mostly, but heated rear window/mirrors were working perfectly. Eventually after various dealers closing and another being a ****, got to a dealer with this complaint and a wonky xenon on the passenger side. As seen elsewhere on the forum, the xenon bulb holder, which adjusts up and down via the switch on the dash, had broken out of its socket, and was pointing skywards. The **** wanted to repair it, I insisted on a new lamp, hence the trek to another dealer. He agreed, replace only, and it took a month to secure a new lamp (with a different part number, so obviously an updated design) due to the parts warehouse move. He scanned the ecu's in the meantime to find the cause of the stop start failure and found nothing. Charged the battery, told us to drive on and see how it goes. He would look again when the lamp was ready to fit. Then in quick succession we lost the indicator and sidelight from this lamp. The **** never fitted the covers back on the lamp and there was now water pooling inside it. So when the new lamp was fitted there were a heap of codes to do with this, he cleared them, fitted the lamp and said see if the stop start appears again. He seemed to believe that the wonky lamp was causing it, and with that now fixed the systems would eventually re calibrate. Nothing for a week, then low and behold, it began to cut in. Slowly at first, didn't stop everywhere, now working perfectly. As an aside, and believe me, I'm as mystified at all of this as anyone reading this entire post might be, the engine seems to have found another 20 bhp/40 lb ft somewhere. The trek to the dealer was 2 hours, I drove to it, and home again. On the way home, and ever since, it is pulling much stronger than it ever has. It has always felt on a par with my 156, as it should have, remapped to 187 bhp/300 lb ft 156 vs 180 bhp/330 lb ft Giulia, similar weight. But it is now in a completely different league. I contacted the service manager to ask if he had updated the software or had done something to affect the change, and he is adamant that he didn't. I'd have paid him if he had, and told him that. It really feels like a mild remap. And, as a further bonus, mpg has improved by about 5%. Make of all this what you will, but to me, as a long term Alfa owner, these are the kind of mysterious wonders you get with an Alfa. As it was, so it remains to be. Car is now fantastic again. Happy, and weird, days.
