Vacuum pump
Hi all,
I think I have a problem with my vacuum pump (secondary air pump / smog pump). It runs continously instead of shutdown after 30-60 seconds ...
I have a video to listen to it.
I don't be able to find the relay of the pump ... Do you know its number in the fuse box ?
I want to try it before changing the pump ....
Many thanks guys, and be safe

I regret to advise that I have checked all three locations that contain relays and there is none for a so called "secondary air system". ,Although we do not see your type car I the USA, I don't think that that system as defined exists on your vehicle and I think we have a translation issue.

If you are correct than I would say its the "low pressure exhaust gas recirculation actuator motor M16\46" part number 276 141 01 25. The voltage to that motor is via circuit 87 and their are two relays in that circuit F58kS and F58kN.--------kS is in the front SAM and is the first relay in the top row kN also in the front SAM and is the last relay in the bottom row-----you owe me some mouls!!
