I have a 2015 Abarth automatic with ~92K miles.
It was exhibiting a P300 for awhile which I was not able to clear. I tried most of the usual suspects: spark plugs, look for vacuum leaks, ignition coils and wire, ground wires, oil change.
It was also occasionally starting poorly like the starter was going out and less occasionally it would stall right after start.
But other than that, the car ran fine and I could never detect the misfire that was throwing the code.
Then the P1062 code appeared in addition to the P300.
This time I checked the multi-air filter and solenoid on the side of the engine.
The next thing appeared to be to replace the brick which I didn't want to do myself so I took it to a dealer.
The dealer replaced the brick (VVA) but also replaced:
VVA gasket
Multi-air Actuator Filter
Crankcase o-ring
Spark Plugs
Spark Plug tubes
Valve cover gasket
Oil Filter
Oil
Air Filter
After doing all this work (more than $3000) the P300 and P1062 are gone but P302 and P303 have newly appeared.
The dealer investigated this further and says that the new brick will not train and stays stuck in SAFE mode.
They said that the brick will not train because the oil pressure is too low for the first 5 to 10s of starting so the brick stays in SAFE mode.
Is there a way to fake train a brick?
I read on one of these forums that maybe an air pressure hose could be attached to the oil dip stick tube to provide a bit of extra pressure during the start up.
Does this actually work? What would be the psi setting for this?
The options that I am being offered are to:
1. Remove the oil pan to look for metal shavings n the engine ($1600) then either #2 (if no metal found) or #3 (if metal found) below:
2. Replace the oil pump ($2700 including the part and 10 hours of labor!)
3. Replace the engine for $9000 (more than the value of this car!)
If I call it quits now, I get back a car that will not drive above 30 mph (limp mode). So I get back a car that drives worse than when I took it in.
If I go with the oil pump replacement, I'm told that there is no guarantee that the problem goes away because the initial low oil pressure could also be caused by worn bearings.
I don't know what to do at this point and could really use some sage advice. The car is currently in Columbia SC, USA.
(I also posted this in Fiat 500 General discussion so I hope it is not against the rules to also post here).
