code 299 said turbo under boost . Some sensor shutting off turbo ?

It stays on while driving. Nothing seems to be wrong. It drives fine and no other symbols come on.

Engine dies when making L/R turns on streets.

My batterie went extremely dead due to something left on in the van and I'm told by someone at the Sprinter Store that it could be a chip that is ruined due to the batterie going so dead.

Would this be the ESM chip?

move put in rev same thing engine run smooth made no noises

my battery died today, and after it was charged it would not let me shift out of park without using the shift release button.

I disconnected/reconnected power, checked all the fuses and they all look good.

im at a loss as to how to fix this.

the engine code states that the particular filter ash is full.
