Hi guys
anyone had issues with vac pumps leaking, had it re sealed by bmw under wrty and then replaced with a modified version again by bmw( different dealer)under wrty again, was fitting my winters yesterday so had a poke about whilst on the ramp and noticed the vac pump looks like it is leaking again, didn't dig too deeply but from underneath there was a drip of oil on the rear of the pump, also rear of box still looks slightly wet but don't know if the oil from the vac pump is working it's way down to there or if i still have a small leak on the box output shaft.
