Default estimated SMG pump life

I have a bit over 100k miles and the SMG cog light came on, but it seems to be the gear selection switch.. the pump holds pressure fine for now

how long should I expect a pump to last?

I am thinking of replace it as preventative maintenance

Mine has 187k miles and still works like new. I've only replaced the accumulator on the pump.

226k on original pump. No parts changed. Don’t get paranoid when you hear users having issues with it, they account for only a small number of smg cars.

123K and live in Las Vegas where the summers are 110-120 degrees, no issues as of yet. 🤞

Was 153K on mine when I sold it, no issues. New owner said it was still running strong at 167K. Don't worry about it. Your clutch likely will go out before the pump does.

Did you change the gear selection switch (or gear position?) after the COG light came on?

My pump motor went out around 165k miles.
Do yourself a favor and just buy a new bürckhart motor now so it's ready to swap when it fails. Mine went with no warning except maybe prime time was a little long, maybe.

I just rebuilt my SMG pump, and would bet the seals were original. I think she's just under 170,000mi...

The pump seals were OK, but the solenoid o-rings were bit to shit. I'm happy I replaced everything and would say if you have the unit out anyways (or easily accessible), go ahead and replace them.

It's an easy job. I was in there because my smg motor failed. (replaced it with Burkhart's and am very happy with the performance of it). AMA

My SMG pump motor started going out around 143k. Replaced it with Burkhart's SMG repair kit.
