Next time the warning light comes on, don't clear the codes with a diagnostic tool right away. Try to find a place nearby that can read detailed trouble codes. Some auto repair shops do it for free. Most likely, it'll show codes related to supercharging, like P0234 or P0299. Or you can get an entry - level code reader like the [link|https://www.ancel.com/products/ancel-ad310|ANCEL AD310]. It's only around 20 bucks on Amazon. Just plug it into the OBD port and it can quickly read the detailed trouble codes. It's one of the things I always keep in my car. [br]
For your situation, I suggest you check if the turbo pipes are loose or leaking air, especially the connections at the intercooler. If the clip on the intercooler joint is loose, it might be okay at low speeds, but it could leak when you're driving on the highway.
