So driving back from CT tonight, I’m in 6th at about 3500ish doing around 80. I had the gas pedal fully depressed and its like the car fell flat on its face out of nowhere. Stopped building boost and it wouldn’t go past about 80mph. Is it possible that the turbo got heatsoaked? The intercooler is stock and I’ve been suspecting for a while that the cat has become clogged. All speculation, because idk too much about turbos yet. Only real “engine” mods are a CAI and a BOV. Any insight is much appreciated
sounds like you went into limp mode. i had a few occassions where my GTI would hit limp mode in 5th(on the 5speed) when i was stock turbo, with my REVO2 file. it would overboost and the car would go nuts and id only get 5psi until i did a hard reset of the ecu. pretty much the same way you described it too, i was on the highway top gear, about 3200rpm(right near peak boost/tq) and suddenly the car would nose over and fall on its face. are you chipped yet? its possible that unchipped with the minor mods you have the car is spiking past the stock boost range thats allowable by the ecu
hmm, it crossed my mind that it might have gone into limp mode. It sure sounds like exactly what you said. Btw when I dropped gear, the rpms would slowly climb but the speed stayed about the same. I don’t know if that helps or not. Anyways, its not chipped yet and everything else engine wise is stock minus an upgraded diverter valve and the revised coilpacks from the TSI. Whats a hard reset?
Did it sputter? Be more specific. If you are cruising along, you should never get heat soak.
Ignition? Fuel?
We figured it out actually… Just hit the speed limiter is all and it went into limp mode lol. Thanks for the help
