Good Evening,

I have a 2014 A5 2.0Tdi Ultra 163. I believe the engine code for this unit would be CGLD.

The car has a dodgy Map sensor that isn't giving a return signal so needs replacing.

Can anybody please confirm if 04l 906 051c is indeed the correct part number for the MAP/boost sensor I require and where would be best to source. Everywhere i go seems to suggest i a need to two bolt variant, and for the the life of me can't find where this would go in the engine.
However on further research i believe it to be a single bolt variant with an attachment for a vaccum pipe. It is located at the rear right hand top side of the engine on a metal bracket and has the above part number printed on it.

I look foward to any replies.

Thanks
Alex

I believe the part number 04l 906 051c is fitted from 2016 to the B9 cars. I think the part number you need is 036 906 051 G. Which is the 2 hole version. Thats just going on the info about engine size and year.

It should be fitted somewhere on the pipe between the intercooler and the intake manifold.

Thanks for the response, i have sorted the issue today and indeed the correct part for the CNHC engine in the 2014 A5 ultra is 04l 906 051c/k single hole map sensor.
The CNHC engine wierdly doesn't have an intercooler so only has the one Map sensor and no lower boost sensor.
