Help please

I have not long since got myself an audi a3. 2.0 tdi sport.

Can anyone confirm, if my relative throttle is 0.0 when driving and the other reading is 85%, does that mean my throttle sensor as had it?

Just for added info. I currently have the p2015 error code and an exhaust temperature fault. The exhaust freeze frame reads when rpm, I guess that sensor is done too.

Also underboosting, suspect either one of these or the vanes, but starting with the easy options.

 

Thank you, sorry for the long post and slightly jumbles post.

Freeze frame read out below.

• Freeze frame DTC = P0544
• Engine load - calculated value = 0%
• Engine coolant temperature = 63°C
• Intake manifold absolute pressure = 100kPa
• Engine speed = 0rpm
• Vehicle speed = 0km/h
• Intake air temperature = 46°C
• Mass air flow = 0.8g/s
• Throttle - absolute position = 90.98%
• Fuel rail pressure = 100kPa

Ps, I still like the car haha

Should add the 85% never changed at idle or driving, and the other reading something goes to 2%

 

Thank you

Underboost error not come back as of a few miles of stop start driving. Other 2 errors are stored as permanent. 

 

Also to show the sort of person that sold me this car, anyone know if the bulb for the mil light can be changed.

Mine seems to not be working...

 

Thanks again, I try and post as much info for the smarter people to help.
