Hi guys, haven't posted in a while as Ive got new job and been working on my new to me 540i6 here and there. I have replaced a lot of parts since i got her in beginning of September: complete intake manifold rebuild, all new vacuum hoses, new maf, tranny fluid, putting new tires on today. But now there is a new issue, when i start the car warm(after i drive it for an hour or so) it makes a loud grinding noise for 2-4 seconds right after it starts then goes away. It happened once before but i didn't pay too much attention as it didn't come back untill last week. Now almost every time i start it warm it makes that whirring noise for 2-4 seconds then goes away and car drives fine, (also the noise reminds me when you have your car started and try to start it again). Few people told me its my starter which makes sense as it only happens during first few seconds when the car is being started. My question is if i drive it like that for another week will this do damage to engine/transmission besides the starter itself. The shop is asking $550 but i just placed an order for new tires and would have to wait at least till end of the week before i get some cash flow. Is it possible to DIY? i have tried searching for threads but came up with nothing relevant to my problem.
Thanks for reading any tips suggestions welcome.
