Why do 124 Benz flood?

The 124-series Mercedes-Benz vehicles, particularly the W124 model, are known to experience flooding issues primarily due to their design and age. Common causes include drainage problems in the engine bay, clogged sunroof drains, and deteriorating weather seals, which can lead to water accumulation in the cabin or trunk. Additionally, older electrical components can fail, allowing moisture to impact critical systems. Regular maintenance and inspection can help mitigate these issues.
