Hi,
I am wondering if anyone has had an issue like this with a 2017 W205 C43 (36,000 km) ?
I had my last in warranty service by Mercedes in February 2019, part of the overall check revealed the following:
“There is an oil leak from the right-hand side of the motor
Checked engine bay for oil leak
No oil leak present
Cleaned are of oil residue
Lifted vehicle onto hoist to check underneath
No oil leak present
Customer to monitor”
I had my service B4 done at an independent mechanic yesterday and they noted this:
“Oil leak from the front diff area, requires further investigation to pin-point source of leak”
They advised that it would take quite a bit of labour to find out the source of the leak as there is a lot of bits and pieces to remove to do the analysis.
Does anyone know if the front differential leaking is a common issue and how bad it could possibly be if not fixed?
Thanks
