Problems with a stuck gearbox in a Peugeot 408

Hi everyone! I have a 2011 Peugeot 408 with 135,000 km and an "Other" type engine. Recently, I experienced problems with the transmission during a trip, where it seemed not to shift gears and the car simply died, locking the transmission. We made repairs to the module and programming, but no warning light appeared on the dashboard. Now, the problem has returned: when I start the car, the fan makes noise immediately and a light with a circle and the number 30 appears on the dashboard. In addition, the brake feels heavy, which prevents the transmission from unlocking. Has anyone experienced this or have any tips on how to solve this situation?

A 2011 Peugeot 408 is experiencing a stuck gearbox issue, where the transmission fails to shift and the car dies, accompanied by a heavy brake pedal and a dashboard light with a circle and the number 30. The problem may be linked to a brake booster issue or a vacuum leak, affecting the brake system and transmission unlocking. Checking the vacuum hose and brake booster for damage or disconnections is suggested, with professional inspection recommended if the problem persists.

It sounds like you might be dealing with an issue related to the brake booster or a vacuum leak, which could explain the heavy brake pedal and transmission not unlocking. Start by checking the vacuum hose connected to the brake booster for any cracks or disconnections. Also, inspect the brake booster itself for any signs of damage. If the issue persists, it might be best to have a professional mechanic take a look, as brake system problems can be safety-critical. Let me know how it goes or if you have any other questions!
