I haven't found a T70 on my e46 but I do have one on my Subaru. You reminded me why I got into SO tools, they are still a lot cheaper than paying someone else to work on your BMW
Actually, it's not only doing the work, but doing the work "correctly"
In a fleet of many cars, all but one 2 of mine are not German. Yet everyone with a set of tools insists that they can 'fix it" a'la "Jeff Spicolli" (Sean Penn) from "Fast Times at Ridgemont High." LOL
I had an ex-GF that had a minty fresh E36 M3 convert. that needed a new battery. I expalined the battery was in the trunk (boot) and needed someone with some sort of "know-how" to access and replace.
She dove in, removed, got teh WRONG battery to replace it with (std. 3 series batt instead of the correct one) and in the process lost all the hold-down hdwre into the abyss of the right rear fender and lower pinch welds where the battery sits.
She went back and got the correct battery but thought the hold down hdwre was unnecessary. Then I got the "call" that things were clunking in the trunk and electronics shorting out.
Hmmm.
They are great cars. Sadly the owners vary from caring enthusisats to OMG cool unknowing poseurs.
I care enough to help those that fix things correctly. But it's seldom cheap. LOL
