2009 E320 BlueTec



The radio is turned on; plays for a minute or so, untouched it turns off (black screen) & immediately turns back on.
It keeps doing this, over & over again. Quite strange... Any ideas?



I am Disabled, so working on cars are difficult for me.
I also need someone to change the Timing Chain, Tensioners, Rail, etc. in my 2009 W211 E320 BlueTec.
Do you have ANY recommendations? I know you are in Arizona, & I live in NJ, but maybe you know someone?



The Mercedes Dealer told me, Flat Out, their Labor rate is $368/hour - (1 hour minimum)!!!
My question is: Will Someone upload the Updated Software for a more reasonable price?
After they figure out the problem with the Xentry Diagnostic tool.
Then the dealer said if I thought $368 /hour was too high, I should try a German Radio Repair Center.
So I called them. They said they would pull the radio out, repair it 100% & put it back in.
Somewhere between $400-$600. I am shocked! The prices are extremely high. BUT I NEED A RADIO.
Any ideas for me.
DIY, install minimum configuration COMAND (head unit) and AGW only using MOST bridge when operating, loop-in single modules until defective device is located. Shop MB part # 0005454484 to pull aftermarket fiber optic bypass. Provide VIN to see what devices are on you loop I will post instructions to access.
Optional if defective device is found. Check with dealer parts to see if update disc 1718270100 is still available should be about $1.
