Solution to a common turbo problem (fault code P023600)?

[BagFullOfHammer]

Hi

I thought I would just share my experience I had of turbo problems with my A6 2014 2.0 TDI Ultra, in case others have the same issues
So what I was happening was the engine fault light was coming on, Coil light was on, and car went into limp/safe mode. This happened all the time, usually when the car was pushed (going up a hill, or accelerating), and it would go into safe mode. It would also occasionally misfire.

Engine fault codes that came up:
P023600 - Turbo charger boost sensor "A" circuit range
P023400 - Turbo Super charger overboost condition
P023800 - Turbocharger boost sensor "A" circuit high input
U111300 - Function limitation due to received malfunction value
P227900 - Intake air system leak
P13D600 - Sensor for internal pressure of cylinder 3 implausible signal

So, I did a bit of looking around, saw that some people had replaced their turbos, but it didnt solve anything. So I went to my local mechanic and told him to replace the turbo pressure sensor (S04L906051K). What a difference! Car back to its old self, loads of acceleration and power, no engine fault codes/coil warning lights!

Good catch!

Having the same issue P023600 - Turbo charger boost sensor "A" circuit range seems to be the one that keeps coming back then bringing the P13D600 - Sensor for internal pressure of cylinder 3 implausible signal, up later on along with EGR. Was your turbo pressure sensor under the turbo or one of them above the throttle body on top of the cam cover near the bulkhead
