Does a 2008 r52 with the w10 engine have a mass airflow sensor or is it part of the throttle body? Trying to fix some rough running and vacuum issues and was going to replace the maf sensor. Ordered one from rock auto that was for the r52, but for the life of me I cannot find it. I did find the manifold pressure sensor. No maf sensor though.

 

There is no MAF sensor, only a TMAP mounted to the intake manifold. Both the W10 and W11 are speed density only.

 

Thank you. What I was thinking. Just needed confirmation

 

No problem. It looks like the second gen cars do have a MAF, so I expect Rock Auto goofed yet again because of the overlapping years of production.

 

That doesn't surprise me

 

Consider using a smoke leak detector if you are having issues with rough idling and suspect that area of the engine. I did this and found a tiny leak in the vacuum system that immediately made a difference.

 

yes. Plan on doing that this weekend. Thank you.
