w211 e270 cdi 2004 ESP defective

[4life211]

Hello all my e class has esp defective message when car comes warm.i scanned and here are some codes:
C152D
C1514
C2495 battery voltage terminal 87 (don't know what does it mean)
I just have replaced trunk battery.




The mechanic doesn't find any solution.please help.

It shows communication is defective. Have you check all connections? Have you reset any errors since replacing battery?

But as your mechanic isn't using STAR it's bit hit 'n miss.

Suggest you find a good Mercedes independent with STAR

So there clearly is an error you cannot clear because there is a faulty component or connection.

A Star diagnostic will be able to locate a failed component etc with much more accuracy than the code reader that has been used and will probably work out cheaper and to be less frustrating overall.

I found there is a problem with my battery drain .when voltage drops below 10 v the esp warning shows up .
