I've had my 2007 450GL for almost a year now. The check engine light has come on at least six to eight times, always requiring a visit to the car shop. Is this common? It's not always the same codes. This last time I was told to change the grade of gasoline. It's quite frustrating and expensive. Any suggestions?

 

Do you have a list of the trouble codes? The should be on your copy of the repair order.

 

usually those engines have issues with the cam adjuster magnets...very very common on alot of benz's

on certain occasions depending on the codes you have the engine could have to be disassembled to fix the balance shaft gear sproket.

 

camshaft and the sprocket needed to be replaced 9600$ bill . my gieco warranty covered it except for 500$ why does a 07 GL with 63K miles need this work?

 

My 2010 GL450 check engine light just came on after 22miles, and I have a 2000 mile return home, do you think that its safe to continue driving ?

 

yeah. youll be fine. 95% of the time.

 

Mercedes had problems with with the Balancer shaft sprocket (rounding off )but it was 95% on the 272 motor not the 273 soo im willin to bet this isnt the problem..what codes did they come up with?
