The check engine light has been lighting up since I purchased the vehicle, about 18 months ago. It has been in the shop 7 times and ecery time code P0456 comes up in the diagnostic test. I have been told this code is for a vacuum leak or some other type of leak, I am not sure. When the leak test is done, nothing comes up and Mercedes Service says they do not know what to do. They have opened an escalation ticket with Mercedes Benz 5 times and so far I have not received any answers. Do you know what this code means? I would like to get the car repaired as I really like it, but I cannot keep the car with the check engfine light on. I am considering filing a lemon law claim, but really do not want to go throught he hassles. Any info you can give me would be greatly appreciated.

Thank you,
Jay Wetcher

I would check with another Benz dealer
as it clear in this TSB that they have a recall on the subject
and for them not to be able to find it make me wonder if they are really trying
I will include the recall TSB
good luck

Diagnosis in DAS for Purge System Codes / Check Engine Light Illuminated
If you receive customer reports in the above model vehicles of the check engine light being illuminated with stored fault codes for "Purge system minor / gross leak" (see following list) in the engine control unit, process the faults using the guided diagnosis in DAS. A guided diagnostic program for the fault codes listed below is available in DAS as of DVD 03/07.

NOTE: Only the parts indicated by the SDS test may be replaced. The engine control unit must not be replaced in the case of the fault codes listed below. All other components being replaced and requested by the QEC for inspection must be accompanied by full supporting documentation (i.E. Control unit log, short test and fault code / freeze frame data from other related control modules). If the documentation is missing or does not support the diagnosis, the warranty claim may be debited.
