Gabe79 410 Report post Posted July 26, 2017 (edited) Irony of ironies... got into the e39 this morning to go buy a Nissan Leaf and intending on trading in the Toyota, much to my wife's dismay... No start, no good. I have a battery pack starter, unsure if it's not provided enough juice though. Cables not long enough to connect to both leads in the engine bay. I tried connecting directly to the battery in the boot, that just set off the alarm and caused the error in the thread title. Now the car has zero juice of its own. The battery might be dead, I suppose, but then it should have started when I tried jumping with proper leads from the damn Toyota... Anyway, this is what it looks/sounds like when I turn the key. crank crank, no start. https://photos.app.goo.gl/YnLNwpj4kwxvRCAJ3 EDIT1: Summary: Key turns, engine cranks (cranked, before I killed the battery...) but doesn't start. EDIT2: I haven't driven the car in a few weeks now, if that matters. Edited July 26, 2017 by Gabe79 Quote Share this post Link to post Share on other sites
qube 3570 Report post Posted July 27, 2017 when you connect up the jumper leads, rev the other car upto 2-3k rpm and hold it there while you turn over the e39. Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted July 27, 2017 Toyota has a special positive clamp on the batter terminal. You may not have had a firm clamp on the terminal Quote Share this post Link to post Share on other sites

You may not have had a firm clamp on the terminal Thanks for the advice. I'll double check both in the morning. Any idea what that ignition lock notice means?

hotwire 352 Report post Posted July 27, 2017 Also, what are your jumper leads like? Cheap sh*t small ones? If so - they are a waste of time & shouldn't be sold. I go out to numerous AA calls where the member has tried jump starting with no success. Is almost always these leads that were used. E39's are a pain with the separation of the jump terminals & you will be farting against thunder to start with a little jump pack on the battery. As Kyu says - connect the leads & run the Toyota for a few mins to get some surface charge into the BMW battery. Ign lock notice? 1 Quote Share this post Link to post Share on other sites

SCA for preference. ? The key key ignition error is in the video above. Might be unrelated. Quote Share this post Link to post Share on other sites

The jump pack he carried wouldn't do it either, had to use juice from the truck. I'm seeing some packs on Amazon recommended from the M5 forums in the US and might get one of the beefy ones next time I'm there. Thank you all who posted. The key ignition note seems unrelated.

hotwire 352 Report post Posted July 29, 2017 I had been using for a couple of years a small 400 amp unit (same as the Power All). While it has had limitations, it has been a great unit & probably started about 400 vehicles. It was though past it's best & I was more often getting the battery & leads out. I recently obtained a new unit (as in pic), it is way superior with about 4 times the output - this i have confirmed. Be aware though, any jump pack sitting unused in the glovebox for 12 months will prove useless in trying to start the vehicle. I often use mine several times a day. Jumper leads - discount the entry level ones, you will probably need to spend $60 -80 for a reasonable set 1 Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted July 29, 2017 Just be aware these units are much bigger than the common little units. Haven't yet started an E39 but cannot imagine a problem with it. On Friday i used it to start a Ford 4000 tractor with a virtually dead battery - started no problem. it actually amazed me. 1 Quote Share this post Link to post Share on other sites

Yeah, the Amazon reviews talk about them starting semi-trucks and 6L engines. Should be just fine for my needs. Related: My battery seems to have a little drain and I'm fairly sure it's a poorly installed hands-free kit from the previous owner. I'll be hunting how to remove that thing this weekend, but anyone have a good auto electrician, or stereo installer who knows their way around e39s without guesswork on their part?

Young Thrash Driver 1020 Report post Posted July 29, 2017 The "Key in ignition lock" message is displayed in one of our Tourings whenever the key is put into the ignition. Some sort of Japan spec reminder that could probably be coded out??? E39s do have quite large batterys, the ones in our two Tourings are only 60CCA smaller than the big John Deere on farm here- the Tourings are cold weather package tho Quote Share this post Link to post Share on other sites
