Maybe you have a faulty ground. Take a jumper cable and create an alternate ground path from engine to the ground lug used for jump,starting. 11.89 is dead. It wil not crank. Use a known good battery for this test.

If what you say is true and you've used a known good battery and/or jumper, I would then be leaning to the starter itself. When my alternator died 3 weeks ago and I ran my battery down to nothing (less than 12 volts) I at least got a good solenoid click. Then when I used a jumper box, fired right up.

So with all you've said, I think your issue includes the starter, but also that battery seems like toast if it doesn't get to and over 12v.

Call AAA and get a proper jump.

Then you'll know.

You are kidding right? BMW’s are 12V cars, jumper boxes start them all the time. There are 5 in my family alone in the northeast, everyone has delt with a dead battery at some point and every one of them has been started with a jumper box.

Come on, stop spreading nonsense. They are just cars with car systems.

The starter is toast.

Can anyone confirm, is the starter on the 4.8 located on the bottom of the engine on the passenger side like the 5.0 engine, or under the intake manifold like the 3.0? Or somewhere else altogether?

I suspect it’s on the bottom passenger side but surprisingly haven’t found much info for changing the starter on the 4.8....ton’s of DIY on the 3.0, so i know the starter is a known issue in general.

You're right my experience is bull.

You made the generalized statement that jump start boxes do not start BMW’s.

I have started multiple BMW’s with jump start boxes, never had a failure to start with a jumper box actually.

I’m not sure what to tell you, other than, you’re statement is not correct and far too generalized. There’s nothing special about BMW, it’s a car just like every other one out there. As someone who does all their own repairs and work on all their cars, it’s frustrating to see information disseminated that is completely baseless and/or wrong. And unfortuantely, it happens often with this brand.

AAA does not have special jumper boxes, if you can’t start your car with your jumper box I’d suggest you don’t have the jumper box charged fully.

Back to the actual question, can someone confirm the location of the starter on the 4.8 before I start digging into the engine bay?

Blanket statements by BOTH of you are likely wrong:

The newest BMWs with IBS and load control modules have demonstrated problems when trying to jump start with any power source. (AAA, another running car or a booster) Sometimes.

Older BMWs - 'many'- will jump fine. Or use a booster box.

My 2012 wouldnt turn over, tried to jump it- no joy. Connected an AGM charger overnight, started the next day. Actually quite maddening.

Its just a car with a 12V system, right? Not quite.

Generally I agree that BMWs arent special; they dont need magic tools or high priests to affect repairs. But there is something odd with this aspect...sometimes... You ignore the POSSIBILITY at your own peril.

It is on the bottom right. You can go to the TIS here: https://www.newtis.info/tisv2/a/en/e...unting/G8qD6u6

Ard,

I have to disagree with you on this statement, high priests are required to affect repairs. LOL

Starters are huge failure items on BMW's and these trucks, I'm not sure where you're getting that from. There's TONS of discussions about busted starters, just not a lot of DIY info on the 4.8 specifically, most youtube videos are showing the 3 liter which has the starter in a different position.
