Basically, the car's driver-side turbo always glows red after driving harshly. After repeatedly throwing the car around and power-sliding with full TC off, the car suddenly starts to misfire and shows the engine light, after restarting the car 2 or 3 times the issue fixes itself. Sometimes the engine light goes away, and sometimes it doesn't for 2-3 days until it magically disappears again. Mechanic says it is the blow-off valve causing the issue and suggested the springs are too soft, but after contacting Zac Motorsport who are very helpful and responsive, they said this cannot be the issue(read the link: https://www.zacmotorsport.com/en-au/...hy-you-need-it). He confirmed the boost lines are also properly fit. I have tried to see if not having a tune was the issue, but after getting it tuned by e-tuners, the car just didn't perform since it was not building boost at higher rpms.
What can be the cause of this issue?
Future plans:
I will be getting the car's engine and transmission tuned by Morendi through ZAC Motorsport once my turbos, intercooler and billet intake manifold are installed. Parts are already on the way.
If one of the turbos is glowing red hot then I would think that turbo is over spinning from not hitting the boost target. Try putting the stock diverter valves back in and see if the problem persists.
Sounds like a wastegate issue on that turbo. I would check all the vacuum lines, AND the wastegate operation with a vacuum tool, as it sounds like that wastegate isn't opening. If the wastegate isn't opening, the turbo will overboost and then just keep trying, as there is no way to control it. All the codes are probably the ecu trying to control, or limit the boost, which it can't. I definitely would not be driving it to the point of turbo glow until it's fixed.
