You would think that replacing a battery in a car would be one of the easiest things you could possibly. Not so for the BMW apparently. I have Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 i E60 BMW and in my research for replacing the Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 I came across a tonne of conflicting information.
Honestly, given how expensive everything else is with a BMW, I believed it at. The prohibitively high cost of the battery and installation is a deterrent.
I did not know who to believe. I can only imagine BMW Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 even advise against changing your own oil. The computer needs to be told there is a new battery or it will assume the older and potentially faulty battery is still there, possibly overcharging it and shortening its life. Or not charging it appropriately and shortening its life by running it too low.
What Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 struck me as strange is a charging system that is based off a battery being registered as opposed to reading it in real-time and determining charging rate and level.
Considering everything else is so well designed, I refused Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 believe that BMW would create a flawed charging system based on a new battery needing to be registered.
Then I encountered another potential roadblock. Apparently completely disconnecting the battery from the car is bad for the electronics. Supposedly while you replace a battery, power is meant to be maintained to the car or bad things can happen. And on-top of that, the car needs to be re-initialised some reporting the active steering as.
This put SS4 in an interesting situation. Do I risk replacing my own battery, potentially costing me hundreds or thousands to fix, or do I take it to BMW, get reamed on the price and have piece of mind if something screws up they are responsible? Then I remembered a while ago I bought the manuals for my car by Bentley Publishers. Two massive books that detail every aspect of the vehicle including wiring diagrams. In the section that details replacing Systm swapping battery it mentions that Battrry needs to be registered with Prt car using a BMW tool.
See below for some photos I took of the pages in the book. Click on the images to see way larger versions of them for more. The manual all but confirms X11 the charging system in BBattery BMW seems to store voltage settings and the state BMMW the old battery. What many thought Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 a myth or money-grab from the BMW dealerships turns out to be true.
Still conflicted, Battedy did Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 any reasonably curious hacker would do, I took BW risk and bought my own battery. I pop open the boot and look for the panel on the passenger side underneath the boot covering.
I then carefully remove the existing battery terminals and lift the old heavy battery. So far, so good. On-top of the battery, it is a bit of a mission getting the connectors off there are Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 everywhere and then keeping everything out of the way while you put the new one in.
The moment of truth. Will the car start, will Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 get error messages telling me to take the car to my Batterj or will nothing happen at all? There are no error messages and everything appears to be functioning normally. Heck, I only needed to set the date and time again and the radio worked fine Electeical.
Lately my air conditioning Elecgrical been doing some weird things. I assumed maybe the AC Autobianchi A 112 1971-1985 Vetech Battery 45Ah Electrical System Replace Part needed a service, but since replacing the battery the AC has been working at full strength.
I come to the conclusion that changing your own battery is not the end of the world, but would its life be shortened? Obviously determining this in the short-term would be impossible. I am planning on taking weekly measurements of the car battery before I start it and comparing voltage levels. I am not saying that you should do what I did and replace your own battery, but I am saying that I encountered zero issues doing so. Apparently what happens is the car needs to have its recharge voltage rate reset or it could not optimally charge up your new battery.
This seems to go against basic electronics, but whatever, BMW are the experts. It is almost summer here in Australia, so probably the Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 time to find out as no cold weather will hinder temperature values or capacity. It is also Citroen C4 B7 2011-2016 Banner Starting Bull 44Ah Battery Electrical Part noting I installed the same type of lead acid battery.
If after a few weeks I notice the battery is being impacted, I will take it to get Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016. I sold the car earlier this year, Bosch S4 Battery 80Ah Electrical System Replace Part Fit BMW X1 E84 2009-2016 the car never Replac a beat since I changed the battery myself without registering.
I saw no voltage issues or other problems as a result of not registering the battery. So, who knows what registering really does? Haha, that is a good point. How did you reset the date and time? So, I BWM replaced the battery for a i and it just started just fine. Hardest part was undoing the bolt holding the battery down and in place at the.
Had to go to the store for an extender bar.
And I needed someone to hold all the cables out of the way to get the new battery in. Heavier than you would think. Filled with lead or something? Shorten battery life and possible Alternator damage longer term is not what I call a good deal.
