I removed the wing to access mine when the filter was blocked , luckily I checked all 3 pumps as they were all the same on my e70 , it worked great for a good few months till I parked it up last year now every time you fill it a day later the tank is empty again

, looks like I will have to go back in again ! The sill cover needs pulled back on the e70 to access the wing lower bolts which of course were very rusty , I couldn't remove the sill cover as the rear screw fixings heads were all rotted

I guess the tank possibly has a crack now ,didn't happen during frost but in the summer
Never got round to the airbag recall either as it was on a sorn
