Mercedes CL550 intercooler
Hi All,
My dealership just told me that I need to replace my intercooler due to a leak. This leak has dripped on a spark plug and caused it to go bad, thus needing to replace the spark plugs and wiring. I'm a bit confused as I thought the spark plugs were covered. Am I being taken by my dealership? I should also point out that they have had to add a small amount of coolant each time I was in for service while it was IN WARRANTY! Not it is not and they are quoting me $4100 to fix the issue.
