Electronic Module Failures

The S-Class is equipped with numerous sophisticated electronic control units (ECUs) managing everything from climate control to engine management. These modules can fail due to age, moisture ingress, or electrical shorts. Estimated repair cost: $500 - $2,500+.

Oil Leaks (Valve Cover Gaskets, Oil Cooler Seals)

Over time, rubber seals and gaskets, such as valve cover gaskets and oil cooler seals, can degrade, leading to oil leaks. These can be messy and, if left unchecked, can lead to low oil levels. Estimated repair cost: $400 - $1,200.
