Hi guys.My name is Krassi.I am from Bulgaria.My frend is owner of new 2008 220cdi E class.But very strange problem appear.when you are inside riding the car you can hear a noise like water is leaking from openbottle...in the official dealer here cant help ,and told to my frend to leave the car in their service for a month.Please if someone from you guys have any idea what can be the source of the noise please help me.
thanks

 

Do you hear noise with:-
Car moving / stationary?
Engine running / turned pff?
Air Con On/Off?
Occasionally / All the time?
Engine Hot / Cold?
Where does the noise appear to come from?
etc.
Need to do some more elimination process.

Leave the car with the dealer for a month.....NOT A GOOD IDEA!!
