W203 C270 loss of power and low boost

[SMP142]

FIXED!!!

Installed a new wastegate actuator and got boost temporarily.

Still had the ESP error, so I figured it was due to that.

I installed a new indicator assembly last year and its been there since. The mechanic said the steering angle sensor was bad. so I did some more research.

I pulled the steering wheel off and set my steering according to this video:

Reconnected the battery, turned the wheel lock to lock 5 or 6 times then took it for a drive. The ESP went away after about 30 seconds.

The car feels all new again. I have boost and more errors.

Hopefully this helps someone along the way.

Do you mean you have NO more errors?
