Part 1: Chasing Interior Water Leaks in Older Mercedes Benz - On Demand Video

Example of diagnosing a severe water leak in a W124 chassis wagon. Principles apply to many models.

Interior water leaks are very common. More so on the older 108, 116, 114, 115. 123, and 126 chassis than on the 201 and 124 chassis. This is largely due to the fact that the older models used rubber seals on the rear glass and on the front windshield (except the 126). That does not mean the 201 and 124 are immune to interior water leaks. Do you want to see a really good example of a large water leak and what was causing it?
