1 series battery

Postby Cmburns » Sun, 20 Feb 2011 21:11:58 UTC

Hello all,

I have a may 08 118d edition es and since the bad weather the the battery seems to be a bit hit and miss, the car runs fine but on occasions the warning light comes on when i start the car, all the electronics have reset, the radio wont turn on when the ignition is off and the auto stop start wont work.

Has anyone had this happen to them? and if so any ideas what i could do before taking it to the dealer to change the battery?

Cheers

Hi & welcome to the 'Land.

3 years seems to be a bit short for the battery to have given up, maybe something's draining it down - unless you only do really short runs? :? I'd get it booked in to be looked at before the warranty expires. :idea: All the electrical 'problems' you describe is the car shutting down 'non-essential' features to preserve power for starting etc.

Hi

Any updates on your visit to the garage?

I have had the same problem. I took my car to the dealer a couple of months ago, they have tested the battery and recharged it - it all works fine.

However, this only lasted for a few weeks later my clock/display resets itselfs again.

I bought a battery charger and it seems to have stop the clock display resetting problem. I went for a 2 weeks holiday after my return the problem has reoccured again.

Even after I took my car to the dealer though my Stop/Start function still not working.

I know I can charge my battery again and it would stop the clock display resetting, but it didn't cure the stop/start function last time.

Don't really want to take my car back to the dealer, as they charged me 99 pounds + vat last time for this.

Anyone have any suggestion whether i need to replace my battery or not? Does it have to be done at a dealer or can I go to halfords or rac to have it done cheaper? I read somewhere halford uses a memory savers function to save all the codes but i am unsure if the codes would be the same for the new battery type.

Many Thanks.

Many Thanks :)

Our late 2008 120d started to do the same thing a few months ago . Lots of short journeys and the battery takes a beating... especially if the car is fitted with efficient dynamics stop and start.

We had a new battery fitted and coded and the car behaves beautifully again now.

All of the symptoms point to a dying battery.

I think there are two separate parts to this. For the Efficient Dynamics start/stop to be working, the battery needs to be in as near to tip top condition as possible and it seems that after 2.5 - 3 years, even of long journeys, etc, the battery will drop below this level, but still have plenty of capacity to last a good few more years, albeit without start/stop working. However, if the clocks are resetting after a couple of weeks, it sounds like the battery isn't even at this level and you can either continue to charge it (assuming you do short journeys) every so often or replace it with a brand new one.

I looked into a new one and they are around 165 quid in Halfords and the suggestion is that as long as you buy one of the same type (ie AGM) it doesn't need to be re-coded as the charge profile will be the same and is just a case of swapping out the batteries. No idea how much it would be to supply and fit from a BMW dealer and you may find as you've already invested £99+VAT towards resolving this problem that you'd only pay the difference for a new battery.

Let us know how you get on !

Yes and no ..... in the case of ours, the stop start feature did become less and less frequent. That's no bad thing really as it's something of a nuisance anyway. It wasn't long after that when all of the other functions started to reset.

I went down the BMW route for getting a new battery. It was £176 in the end for the battery and the coding. The jury is out regarding recoding. In the end, I figured it was worth paying a little bit more for peace of mind and to get a BMW warranty on it.

I just called bmw in Coventry, he told me there was a few different options with the battery re: capacity, I told him it is the AGM version that i needed with stop/start. He said there is very little difference in price, and it would set me back a further 321 pounds inclusive of VAT and fittings.

176 pounds sounds like an attractive price comparing to what they quoted me. Not to mention the 99+vat i had to pay initially.

I wanted the bmw warranty and guaranteed, but at nearly twice the cost i am not sure if I can justify having it fitted there.

:(

You have a couple of options here:

Firstly, try another dealership and compare quotes. Your dealership may be less hungry for your business.

Secondly, ask whoever you ask to quote for a "four plus" discount. Many dealerships subscribe to the scheme so as to retain custom from people with older cars. Ours was 3 years old when we got the battery changed and we still got the discount.

Obviously, best is a combination of both options.

Finally, look for a decent BMW specialist - just stick a post on here asking for recommendations in your area or, better still, do a search around here viewforum.php?f=15

A good specialist should be able to install a decent battery and properly code it.

FWIW, the battery that we bought was the mid sized capacity (cannot remember what size and cannot check the car at the moment). I'm paying Surrey prices here and figure that I either did exc eptionally well or that you are being ripped off !

Good luck.

Hi everyone,
I have had the very same problems so BMW must have an issue here. I bought my 118D SE new in April 2008 and the stop/start stopped working after about 18 months. It took 4 visits to the main dealer to sort it out over a very long period of time but they eventually replaced the battery under warranty just before the 3 years ran out.The car had covered less than 20k miles at this point. Last winter the car had little use but in April the clock on the dash and radio stopped working and the stop/start packed up again. At the next service I was told that as I was using the car for short journeys only it was my fault! They charged the battery and all was well with the clocks but still no no stop/start . but a couple of weeks ago the problems have re occured no clocks, battery low indicator, and now a DTC fault showing. My main dealers now say I need a new steering sensor (at 30k miles!) cost £500. Today I have read a thread stating that BMW USA have recalled the 1 series as there is a problem with corrosion on guess what the battery terminals. At last we may have a solution to our problems. By the way I checked my battery today and it only registerd 40% charge :?: on my smart charger despite a recent 500 mile round trip to London.
Regards
Dave :?:

One problem that can occur is that the dealer changes the battery but forgets to register it to the car. The electronics think the old battery is still in use and charges the new one too aggressively which kills it in less than a year. You can check if this is the case with yours since the dealer diagnostics will show when a new battery was last registered and at what mileage.
