in my ongoing issues with my car....discovered a new one. pump runs for a good 30 seconds on entry boot lock doesnt always open on fob and has to be opened manually with key. after I have done that it seems to work fine. so... 1) could a sticky mechanism be stopping the pump from cutting off as it cant open the boot lock.? 2) how does the pump know to stop pumping? 3) would a leak in the boot line be able to cause this? 4) should I torch this fecking thing and take the Â£5k it is insured for!?!?!?!?
