Generally, the steering wheel lock can be quickly released by turning the key while applying force to the steering wheel. If such a situation is encountered, it is necessary to immediately go to a 4S shop to seek professional repair. Let the transmission computer relearn; or directly replace the transmission computer.
I once experienced a transmission issue with my Peugeot 508, where there was severe jerking and unstable speed during driving. I believe common causes include aging transmission fluid, sensor failure, or control module malfunction, which can lead to shifting difficulties or warning lights turning on. Basic checks: First, inspect the dipstick for fluid level and any signs of leakage. If the fluid is fine, use a diagnostic tool to read the fault codes and identify the specific problem. Don't attempt DIY repairs—Peugeot's automatic transmissions are complex, and professional repair shops are more reliable. Solutions may involve fluid replacement or part repairs. Regular maintenance, such as checking transmission fluid every 60,000 km, can prevent issues. For safety, if a fault occurs, pull over immediately, turn on hazard lights, and wait for a tow truck—avoid risky driving to prevent accidents. For prevention, avoid sudden acceleration and deceleration in daily driving, and maintain moderate fluid temperature.
When I first bought my Peugeot 508, I also encountered transmission issues where it suddenly got stuck in D gear and wouldn't move. I was panicking at the time. The simple steps are: turn off the engine for a few minutes and restart to see if symptoms ease; if not, check the manual mode switch to test if it's a mechanical issue. If warning lights flash, don't force driving—head straight to a repair shop or dealership. My experience as a newbie taught me that prevention is key. The Peugeot 508's transmission is prone to faults as it ages, so I recommend checking fluid levels every two years to avoid oil degradation. Repair costs can be high sometimes, but safety comes first—it's more important than saving money. After towing to the shop, technicians will connect a computer for diagnosis; replacing a sensor might solve the problem. Reading the owner's manual guide more often can save a lot of trouble.
