Map sensor error code HELP PLEASE

[aclarke88]

I'm getting an error after I swapped turbos, car was parked for about 6 weeks, can anyone with code knowledge point me in the right direction? I checked both clips on the sensor and they seem to be seated properly. Are both bad or is it just one?

Are you sure it is not the map sensor on the charge cooler? That one is kind of a bitch to remove but you could clean it with map cleaner. Also do a good log of requested vs actual pressure and see if the issue is all the time

I’d unplug battery first so it resets old ECU parameters and drive around then see if code returns.

Do you have a picture of where it is on the charge cooler? And I'll unplug battery tonight and give that a try

Does anyone know how difficult it is to get at the MAP sensor? I want to try and clean mine and or replace it. I don't do a lot of engine work but would be willing to try unless I need special tools? What's involved when trying to remove the MAP sensor?

My car is a 2013 S7.

There are a total of 3 map sensors on the car.

One located by each bypass valve located on top of the engine. Very easily accessible.

The third is on the passenger side of the intercooler.

It’s accessible, but tight.

Two torx bit bolts hold it in place on the passenger side of the intercooler.

Check your connections at all three.

Thanks for the info!!
