Default Short in fuse F40 (Intercooler pump) Possible causes?

Hey guys happy new year!

Awhile back, my indie noticed a short in the fuse f40 which I believe is used for the intercooler pump. Every time tried inserting new fuse it blew, the guy at dealer made a guess that it could be intercooler leak and needs to be replaced, unfortunately extended warranty wont cover that.

Has anyone else had this issue? Does this sound like the most probably cause or what other things should be looked at?

And lastly how bad is it driving with this issue?

Thanks

Does it blow right away without the car running (or powered on)?

If it blows after you start the car, then it most likely is a bad pump pulling way too much current. You can test this by unplugging the pump wiring and see if the fuse still blows.

They are fairly easy to replace and there is a good Bosch upgrade over the stock that you should consider. There are some really good threads on this process.

Good luck.

Well you should be getting a reduced power message once it warms up.
