Vibration when adaptive braking is engaged
Over the past few weeks, I feel vibrations in the brake pedal.
Here is the scenario:
Adaptive cruise engaged, I'm at a stop light behind a vehicle, however ECO S/S is off and the vehicle is running, but the brakes are hold by Distronic Plus (this is the easiest way to reproduce the issue).
Engine and transmission mounts are changed at 85k miles, Vehicle is currently at 96k miles.
Dropped off the Vehicle for another service and found there is an engine oil leak at the cylinder heads.
1. Is there a recall or bulletin for this issue?
2. Will that part be touched during a 100k service (done recently at 95k miles)?
At 1:00

Is what they replied when is asked your question.
How screwed am I? How much does an Indy mechanic charges? Can it be fixed outside MB?
Are there any recalls on this?

Probably the camshaft solenoids that are leaking, super common... can be fixed DIY, indy or MB. Bigger issue is to check if oil has migrated into the harness.
As far as the brakes, do you feel a vibration when manually holding them (w/o distronic)?

And oil hadn't seeped into the harness, MB replied.

Hello, is there any chance any one can suggest how much this fix would cost if I go with Indy shop? The dealer is asking for close to $1500.
None of the Indy guys want to give me a quote without a separate diagnostics fee (on top of the actual work cost).

brake pedal vibrations
Raja, you know it sounds really odd to have brake pedal vibration when the car is fully stopped. This is commonly caused by warped rotors... but only when the car is in motion.
It could be your ABS electric pump doing some yoga exercise to pressurize the lineset for adaptive brake "Hold"... does you car feature a vacuum pump ? How long ago were your brakes last worked on?
Get your brakes scanned for safety concerns!
