2 Answers
To manually open the exhaust valve of a BMW 7 Series, you can directly use a screwdriver to pry open the valve flap inside the exhaust pipe. If you want to keep it open for a long time, you can wrap the valve with wire several times to secure it. The BMW 7 Series is an imported model positioned as a mid-to-large-sized luxury sedan, with a body structure of a 4-door, 5-seat three-box car. The vehicle's length, width, and height are 5250mm, 1902mm, and 1498mm respectively, with a wheelbase of 3210mm. In terms of suspension, the BMW 7 Series features a double-wishbone independent front suspension and a multi-link independent rear suspension. Exterior-wise, the BMW 7 Series continues the mature and stable styling of the previous model, with the front grille's double-kidney design enlarged and the headlights connected to the grille adopting an upward-slanting design.
As an avid car enthusiast who frequently tinkers with vehicles, the exhaust valves on a BMW 7 Series are typically electronically controlled, automatically opening in Sport mode, but manual operation isn't so straightforward. First, you'll need to locate the valve position, usually beneath the rear bumper, but forcing it open manually or prying it directly could damage the motor or wiring. The safer approach is to install an aftermarket valve controller, like Valvetronic, which connects to the OBD port and allows control via a smartphone app—simple, safe, and fault-proof. Before modifying, remember to check your vehicle's warranty to avoid voiding coverage due to alterations. Also, avoid unnecessary valve adjustments to prevent exhaust system imbalance, which could reduce engine efficiency or increase fuel consumption.
