Hi all, I've just posted my newbie-thread, unfortunately I've mentioned there's been a very odd and big issue, and I'm looking for some opinions please.

Just in nutshell: my Bravo, The Tazmania Devil, according to the previous owner, had no issue like this before. He looked very honest, even told me stuff I'd no chance seeing, had all paperwork, M32 was done as well, car seemed well taken car off.

After buying the Bravo, driving back home 20 minutes on a bumpy road went fine, but then reversing on the driveway, after few seconds the engine slowly died. I thought it has Start-Stop, which hasn't got, so I didn't think much of it, but a bit later it didn't want to start again.
After 30min wait, it started right up.
Talked to the seller, I said let's wait and see.

Then next day, I went to register the car on my name, a few quick engine start-ups went fine, as the station had to checks vin numbers by law, but when all was done, the car didn't start again. After 45 minutes it fired up suddenly, but 2 streets later the engine CUTS OUT during drive! I barely managed to pull off a busy street. Bit of wait and car starts again, I'm very stressed, but thinking it must be something of a small issue, I drove home those few streets.

Next day, on Saturday afternoon I went for a 30min drive, it was really nice, but after reversing to the parking bay, the engine slowly cut again, and didn't want to start.
Hill-start and ASR, ESP lights come on usually, but they dissappeare after few minutes drive.

Sunday I drove to the seller, we checked the car and found the fuel cap broken. I was thinking that may be the issue, the seller felt bad and gave me 4 alloys, which I payed 50% off, I needed them for winter anyway. I didn't want to give up on the car, so I carried on.

Unfortunately I couldn't even driven off, the engine didn't want to start. I waited an hour, still nothing, so left the Bravo there and came home. Thanks mum for the lifts.
Today, I went back and engine fired up right away. Changed the fuel cap too. Then 5 min later, I had to reverse back due road closure, then in 2nd gear, with a sudden jerk, the engine cuts out again. I bought a not-cheap but simple OBD scanner, only one in my area, and the fault code mentioning Turbo Solenoid came up. I deleted as could've been an old code, but the car still didn't start, even after an hour wait. No more fault codes after that either.

2nd time the car has been parked on some street far away from me, as it stalls so often, it can't even make a 5 mile trip back home.

What I've noticed:
-the battery was suspicious, but it's only a few months old and has 13v.
-Half of engine cuts happen shortly after reversing
-No EML light. The occasional ASR and ESP lights go away after 1-2 minutes drive.
-apart from the Turbo Solenoid code, no other codes shown, but it's a cheap scanner. I'm getting Multiecuscan, but order takes over a week.
-Brake light switch has been changed, brake lights don't show when they not supposed to.
-engine temp solid around middle
-no beeping sound, the engine just cuts out like it has Start-Stop.
-Chip tuning is 2.5 years old
-Oil bit dark but been changed 4 months ago.
-After a few hours wait the engine fires up, but cuts out soon enough, then requires many hours of wait again
-During driving sudden jerk and engine dies(2 times) or after reverse parking (8-10 times). These happened in a span of 4 days. For now, my only suspicion is Turbo Solenoid failure, perhaps the turbo over-heats and cuts the engine.

QUESTIONS: I've found the 1.4 t-jet Turbo Solenoid part number, 55203202/70060700, but can't find info on it's location, and how to change it. Any link on that?

With the chip-tuning is around 150hp, so should I look for part for original 120hp verison, or 150hp version?
I've good basis with cars, I'd changed Throttle Bodies, adapted EGR etc, but never had a Turbo car.
I'm going back tomorrow as well, I may even make it back home...
Thanks in advance, any help is appreciated.
 
That's interesting, the issue things like that don't get flagged up unfortunately, so even on engine idle, it'd be 100% ?
It shouldn't be 100%. Actually, the turbo, as shown, is just 5% turned on. The problem is that the pressure value - 1011.17 mbar is as if the turbo would be 100% on. That if you don't have a Performance Turbocharger, where the max. pressure value is double, 2000 mbar and that 1011.17 on screen would probably be correct in that case. But... the turbo on yours is standard, right?! So... as I mentioned above, check for vacuum leak.
 
The recorded pressure is kind of the same as the atmospheric pressure. That means, I'd say, that you probably have a vacuum leak there. You should throughly check for vacuum leak.
I've checked the hoses, I've only found 1 dent but no leaks, on one of the turbo bypass valve. That was on idle, so definitely not good the pressure is literally on max. Yes the turbo is standard.
Could it have been a bad bypass valve, which is always open?
The battery is charging now, so later I'll check the new Bypass valve for codes. Cheers

Yes, it could. And it also kind of suits to this particular behavior of working ok while cold and not ok while hot. But that is to be tested, if this was really the cause.
Hope that new valve fixes it!
 
If (knock wood!) the valve was not the culprit, you should check some metallic components for vacuum leak I think, as when getting hot that could get loose.
It's important to put the scanner on and see how's the pressure when engine runs ok.

Hi guys, unfortunately I've run out of ideas and things I'm able to check and change.
Even with all I've done for 2 weeks, the engine still stalls and refuses to restart for a hours.

I've given up trying to fix this myself, I've spent a lot of time and money as it is.
I'm arranging a car trailer now, and gonna call the nearest Fiat service tomorrow, it's like 45min drive away.

Thanks for all the advice and infos, I'll update when I find out what's the problem. Cheers
