Does anyone know the difference between the S4 and S5 boost sensors? One is listed as N318 and the other is N370. I have a S5 one that looks to be dead (need to do a bit more testing), and the S5 part number is on backorder, but I could get a S4 replacement tomorrow. Are they interchangeable?

Its for a completely stock S5 T2

 

no, the S4 one uses 4 wires, and the S5 only 3.

 

drat, I figured something like that would be the case. Thanks

 

The voltage outputs are also totally different, so it not like you could rewire it to work properly with your ECU.
