2011 X5D...check engine light and fans not working!

Hi all

Been a while since I posted here (meaning I've been happy with the X5D). 69k miles now and first check engine light came on yesterday. Also noticed the blower fans are not working at all. However, when I turn the front defroster on, the defroster comes on just fine (different motor?)? The LED console display lights up fine with the fan increase/decrease as usual and if I turn the AC on, I can feel cold air lightly so it seems just the blower at this point.

Last couple of days, I was also getting a "battery charge dissipated" warning. Googling and reading forums indicate it might be the Final Stage Resistor (FSU) (which also drains the battery per research?)? Or is it the battery itself (stock batter..69k miles now).

Going to a Indy shop this weekend to get the rear brakes done so I guess one more thing to add to their wallet .

Thanks!

Just replace your battery. No question. I picked up a Bosch AGM at pep boys for ~$200 out the door. Installed it in the parking lot. Registered it with Carly for $10.

I caution you to allow the Indy to chase after codes and issues with these failing batteries. Fix the battery first, IMO

There is one HVAC 'blower' in the interior, but the engine compartment devices are usually called fans.

Nope, same blower, but all the flappers are shut except those directing the blast on to the windscreen. You hear the pressure velocity of the now small discharge area.

The HVAC compressor should always be on - snowflake icon lighted - and the Mode in AUTO for continuous dehumidification.

The Final Stage Unit is a semiconductor stack in LCI. In older models it may be a semiconductor switched resistor stack. Properly it does not drain the battery.

ard - What's the exact part number of the Bosch battery you bought? Is it this one below:

Bosch Premium Battery
Part #: 49-850BAGM| SKU: 838838

My battery is due for replacement and I'm trying to make sure that the dimensions of the new one will fit E70.

Battery size is specified by Group, that also specifies terminal arrangement and AGM vent.

Doug - How do I tell the group from this info (see pic). I don't see the group info on here; should I be looking elsewhere on the battery. I just have a pic of the top.

From internet search, looks like it's a H8/49. Not sure what L5 means though.

^ I called couple of indy shops locally but no one is willing to install and 'register/synch' the battery if I buy it on my own (from Pepboys,etc).

Cheapest qoute I was given was $320 out the door (same place that services my X5 currently) so I guess I'll go with them.

There should be a store near you. I recently bought the carly app ($44.99) and I think register battery is another 10.00 so you'll still spend less (the adapter is 75 or so but you'll have it for future uses)

People pay 450-500 for changing battery at dealerships; 320 is pretty good IMO.

Sigh. Buy the Carly app and press the button yourself. pepboys will install it for free.

You are already bringing it to a shop? Just as an aside, ask "hey, I had to replace the battery- can you guys reset it, I think BMW calls it 'register', when you are doing the troubleshooting?" Casual...Prolly too late now.. Or really buy the carly

You know from experience that we ALWAYS ask "whats the code". If you have carly you will be able to tell us, and we can give you a heads up so you might not get totally screwed by the shop.

BMW owners should not accept a 90 AH capacity battery without good reason. I believe that the current BMW specification is 105 AH.

90 AH will work but will not serve as well or as long.

I've already said in another thread, the battery tray in some of the pre-lci models is not large enough to accept a 105AH battery. That battery is physically bigger than the 92AH battery that is currently sold as a replacement for the old 90AH battery.

See this thread for the battery replacement details which were part of SI B61 30 14 http://www.bimmerfest.com/forums/sho...5&postcount=12

Quote:
Replace the battery with a 105 Ah battery (this is an upgrade from the originally fitted 90 Ah battery). Refer to ISTA Repair Instruction 61 21 010, "Remove and install or replace battery" and proceed to step 5b. The following exceptions apply:

If the vehicle is an E70 or E71 and was produced prior to 10/2011, replace the battery with the 90Ah battery and proceed to step 5a (these vehicles cannot accept a battery upgrade to 105 Ah).

If the battery installed in the vehicle is already a 105 AH battery, replace it with a 105 Ah battery and proceed to step 5a.

Important note: F06, F07, F10, F12, and F13 vehicles will require an additional hold-down clamp (P/N 61 21 7 592 923), only if upgrading from a 90 Ah battery to a 105 Ah battery.

Interesting. Is the Group size necessarily different between an 90/92 AH capacity AGM battery and a 105 AH? It has been my impression that the change in capacity was due to better (packaging) technology.

The BMW instructions cited make no mention - that I noticed - of Group size. My primary reference has been following part-number descriptions through RealOEM.

The 92ah and 90ah are the same physical dimensions, the 105 is not. I replaced my original 90ah with a 92ah battery, after initially looking for a 105 and then realizing that it simply would not fit.

Assuming the 105 Ah fits my car (MY2011 diesel) . . . does the 105 Ah require "reprogramming" versus the simple "registering" that Carly does?

Not sure if the above question is even a valid one - i.e. is there such a thing as "reprogramming" (versus simple register) . . .

Thanks.

It depends on what size your car has now. If it has the 105ah, then you just need to register the battery. If its a different size, then you need to go through the retrofit process (programming) via ISTA. It really doesn't take long though.

Carly will also let you specify ah from what I recall on my 650 a couple of years ago. Just another option for an alternative tool.

^^^^

I didn't realize Carly could also register the Ah for the charging profile.

As a side note - I am quite underwhelmed with Carly . . . its UI (relative to the previous OBD I had) is quite pathetic (way too many clicks/touches needed to do basic stuff) . . . that said, Carly is needed for BMW specific codes . . . ideally, Rheingold is the answer . . . just wished they offered a Rheingold Lite on a tablet or smartphone platform . . .

Hi All

UPDATE: Had the battery replaced by my Indy shop last weekend (rear pads as well) and everything is hunky dory now.

The only thing was the check engine light remained on AFTER the battery change for a whole day and then went away mysteriously the next day.

Driving like a champ now. 70k miles now without a single issue to this day!!

Off topic :
Traded my MDX for a new 2017 GMC Yukon Denali (all options decked out!). LOVE that 6.2l V8. But we've traded ..I now use the X5 and wifey gets the Denali (yes...soccer mom syndrome ;-))
