What could be the cause of the cold noise in the Volkswagen Touran?
Years 2015-2023

Answer

If you hear an unusual noise when the engine of your Volkswagen Touran is cold, it may be useful to examine some possible causes: Timing belt: Check if the noise is coming from the timing belt. A loose or worn belt can cause squeaking or whistling noises. In this case, it may be necessary to replace the belt or adjust its tension. Alternator belt: Also check the alternator belt to make sure it is properly aligned and not slipped or worn. A defective alternator belt can cause squeaking or squealing noises. Power steering fluid: Check the level of the power steering fluid. If the level is low, it may cause noise during low-speed maneuvers. Check if the level is adequate and, if necessary, fill it with the recommended fluid. Tensioner: There may be a problem with the tensioner, which could cause noise when the engine is cold. Make sure the tensioner is properly adjusted and does not show signs of wear or damage. Exhaust system: Check the exhaust system for loose or damaged components that could cause noise during engine operation.
