Sir, well done. Very instructive. Is there a way repairing those IBS ?

Hi , i have an e93 08 , i have some issues eg windows only work using key in drivers door but nothing from any switch in the car, mirrors work from the master window switch but not the windows, put a new battery in and says that the health is 39% on it checked through bimmerlink! Ran a diagnostics and “ibs sensor” has come up as faulty but car drives perfectly fine, any suggestions? Thanks

[@johndujany5426]

Is it possible to drive without this IBS ? What is the disavantage ?

[@jtaylor2563]

My 09 BMW 128i base does have a IBS and just swapped my 2nd battery yesterday finally dead it was put in on 05/2014 that is over 5 years old average on both of them being the car was built on January 2009. I used a 94RH7-AGM w/ 1000 cranking amps Auto-Craft Platinum series battery.

[@Pro7aikolol]

Is your oil sensor inaktive after turning off the ibs

[@lawrences1347]

Had my car Valeted and it wouldn't start afterwards. Turns out they got the battery wet. Followed this video and it's alive again. Thanks mate. Mine was an older style with no plug on the negative terminal, instead I removed the blue plug on positive and the small blue plug further up the loom.

[@DjDestinyChicago]

Mine was in an accident that caused the steering wheel airbag deploy. I replaced the positive cable and it has power again, but still won’t start. Should I try this?

[@DjDestinyChicago]

Just tired and the car immediately started!

[@urighht]

I am planning to by a BMW from the auction was running but Steering Lock came on and supposedly the piece you speak about is the reason or low volaltage or the steering was yanked really hard one way i have read but my question once you removed that negative battery and put the new one on how did you or did you have to reprogram your battery and did the car start? Thanks

[@greasemonkeychef]

Will a bad sensor also cause the alternator to output a low voltage, making it look like a bad alternator?

[@sethjones1833]

Yes

[@juandontworryaboutit4150]

Yes, it will cause loss of power, crank no start, can give u bunch of codes, engine/transmission malfunction, misfires

[@TheDisruptiveYouTuber]

So... did it work? Did your car start?

[@mehow102]

Word of caution when doing this. Yes, it works great, but you need to have this part replaced sooner rather than later. This causes shortened battery life due to the system continuously overcharging the battery.

[@tykendrick800]

@@elbakaa I can only speak for e90 328i no start stop. I have older camaro that have the same battery for over 6 years. Ibs is BS Un needed electronics. Older cars don't have that sensor and they don't just randomly overcharge the battery either.

My engine has started cutting in and out intermittently after doing some recent work. During which I removed the negative terminal. Now it cuts in and out like an old fashioned car with a doggy connection to the ignition coil. But it only does so at around 2500 rpm with gentle throttle, If I accelerate it goes away.

@3RD CAV thanks for the reply bro ✌ unfortunately I already have a new starter and no fault codes in INPA. has to be some electrical issue..

@3RD CAV I just figured it out. For me it was the small control wire plug on the starter, it was loose but just a few mm (you wouldnt notice by just looking at it). Pushed it back in and voila, the car ran like nothing has ever happened :D PS: I had the same issues as you stated before but for me it was the injectors, sparkplugs and ignition coils. Replaced them and everything was fine again.

Did your battery catch on fire an year after this "mod" ? For those that don't know, this sensor is there to reduce the charge after the battery gets older. Therefore it will get overcharged, Wich is fire hazard.

[@tvguy12346]

FYI BMW owns RR

[@miguelhernandez8942]

Whats about the small wirelles the Blue one whit red

[@E28Source]

Miguel Hernandez those seem to be unused.

[@fuzzybizzuny]

It didn’t work because all he did was disconnect the ibs from the distribution box. The ibs is integrated into the negative terminal. In order to disconnect the ibs, you have to disconnect the neg terminal. Otherwise you have to replace negative terminal. It’s not a separate piece. And if the ibs is faulty, because it’s attached to the neg terminal, it’s causing a bad ground. All he did was disconnect the adapter leads.
