I've had my 57 plate 8P2 S-Line Quattro (170 PS) less than two weeks from the dealer and I've got a warning light already! Got myself an interface cable and VCDS-Lite. After much faffing about with ports, latency and software versions, I've determined the fault, "001137 - Exhaust Pressure Sensor 1 (G450): Implausible Signal P0471 - 006 - Short to Plus - Intermittent" I'm glad it's nothing fatal since I didn't take it straight to the dealer (although it's still under warranty). Since it's an "implausible signal" is it something I can clear and see if it comes back? The car needs to go to the dealer to recode a spare key anyway. What say you oh wise ones?
