Some common problems with the Volkswagen Passat include failure of the engine, oil leaks, breakdown of the Anti-lock Braking System (ABS), digital display failures and defective ignition coils. Other problems include wear in the camshaft, failure of the control modules, malfunctioning spark plugs and electrical problems.
Neglecting oil changes, driving a Volkswagen Passat with a low oil level, excessive overheating and poor maintenance can cause engine problems. A substandard camshaft chain tensioner and a worn out valve cover gasket can cause oil leakages in the engine. A faulty ABS control module may fail internally causing the warning light to illuminate. A depleted battery or poor driving habits may lead to failure of the digital display on the instrument cluster.
A rise in temperature, electrical surges within the ignition coil and failure to maintain a mid-level resistance can lead to malfunctioning of the ignition coils. Lack of frequent oil change and excessive valve clearance can cause unusual wear in the camshaft. A faulty fuel solenoid and a flawed injector wiring can cause the breakdown of the engine control module.
A faulty carburettor, defective insulator and incorrect tightening torque can cause the spark plugs to misfire the explosive mixture in the internal combustion engine. Misalignment of shafts and timing pulleys, excessive load and weak drive structures can lead to wear and tear of the timing belt. A blown fuse, poor battery terminals and a tripped circuit breaker can cause electrical problems in the Volkswagen Passat
