Why does the old Passat have a strong smell in the cabin?
1 Answers
If the old Passat has a strong smell in the cabin, it is recommended to check whether the car's air filter needs to be replaced. Delayed replacement of the air filter may lead to strong odors inside the car. There are many reasons for the heavy smell of exhaust in the cabin of an old car. It could be that with the windows closed, the external air circulation is turned on, causing exhaust fumes to enter the cabin. There might also be a leak in the engine's emission system. Additional information: If the car is equipped with an exhaust gas recirculation system, it could be due to abnormal operation of this system. Another possibility is poor sealing of the car's weatherstripping, or engine operational faults that require related inspections.
