Is my car issue Body Control Module or Comfort Control Module? Please help!

[khawari]

I would not come here and ask this question how do I not known the answer myself.

Frustrating part about my issue is that after I thought I had a particular problem and I was looking up online how to replace that parts I'm getting strikingly different results.

A YouTube search and my country in Canada shows a mixup between the body control module and the Comfort control module. I saw a video here https://youtu.be/Ur9Net2xgiU

The guy in the description clearly calls this a body control module slash Comfort control module. So apparently they are the same according to him. However, the part that he has and has hand and in the car looks nothing like what I find for a body control module on eBay. Furthermore, the parts that I got that you will find on eBay when you type body control module is the same part I was able to source here and my city throw mechanic. Sorry not a mechanic but junkyard guy. One I gave the junkyard guy the part number for the body control module, he asked me if that's the part that's under the seat and I told him I think so however I'm not sure I just know the part number for the part that I need. He comes back to me and tells me you found the part and he kept that aside for me and he eventually sold it to me.

I posted pictures of the parts that I have.

The worst part is, one I look up Comfort control module on YouTube I get this video with shows a part that is under the steering wheel.https://youtu.be/4uljuO9FuOk

Now, the problem I am having has to do with electrical the controls the lights, the hazard lights, the windshield wipers, and the fog lights and light switch that's on the side. As well as the lights that are feeding the instrument cluster which gives you your speed reading and RPM.

I need to have a clear answer whether this issue is a body control module, or a comfort control module. There seems to be a huge issue with this car and this model when you try and search this issue. The entire internet is riddled with so much miss information that it's almost a reason not to buy this car because of how ridiculous it is for people not to to know what the parts are in what they're called. I really don't know why it's very difficult to know what this is. All I know is that trying to connect a reader to the car to get a code error is not even something that I can do because I'm having a electrical issue so which module is it?

And how do I replace it?

The second question is this kick trim panel piece that the audi has. When I was removing the carpets of the floor of the car to try and figure out if I can access this box underneath the driver seat, this piece that some point came off and I don't know where to put it back. https://parts.audiusa.com/p/Au...-WA...8E0867191.html

PLEASE NOTE:The part I posted as a picture is one I don't know if I need. I am just unsure what to replace now. The parts guy who sold me this said oh the part under driver seat? And this is not the part. Then again, I don't know which part I would need to replace now. As there are so many names to the same parts... IMG_20190329_185558.jpeg

Your symptoms indicate a bad BCM which is located underneath the dashboard. Clicky click®

Where is that located exactly? Do you happen to have access to a guide somewhere? It's frustratingly hard to find

I can see why. This video is for replacing the BCM but is erroneously called the CCM. Clicky click®

Any idea how I can fix the BCM and access it? I took apart part of my carpet and almost the driver seat only to realize I had to undo it all because YouTube is filled with junk.

Also,

For my sake, would you be so kind as to explain the differences between a body control module and a comfort control module?

Lastly, I would like for you to try and point me to the proper guide to see how I can fix that if possible. I want to know how to replace my body control module that would be very much blessed thank you man

The BCM (AKA: CECM or Central Electric Control Module) controls the outside lighting. The CCM (Comfort Control Module) controls interior functions.

You need to remove the kick panel underneath the steering wheel to access the BCM. There are three 8 mm hex head bolts holding it on. One of them is underneath the fuse panel on the left side (you have to pop the fuse panel cover off to see it) and the other two are under the front edge of the kick panel.

Once you remove the three bolts just pull forward on the kick panel and it will disengage. If you want to take it completely out of the car you will have to pop out the puddle light. That should give you free access to the BCM. There are two bolts as shown below holding the BCM in place.



From the bottom of the BCM you unplug all connectors and remove the unit.

My wipers though are also getting affected as a result of the BCM. Does that make sense?

Yep. Another outside function.

[khawari]

Yep. Another outside function.

So why is it that it failed right when hazards failed?

They only do this when hazard light doesn't continue to go off

What other part would be responsible for wipers in that case? And apparently my instrument cluster and also the sensor for rear fog light, because all of these will show a sign of failure either by clearly showing its not working properly, or a symbol on my cluster going off then on off then on etc.

It all began only when my hazard lights started, and recently, my hazard lights would go off and the wipers as well continuously flashing and wiping non stop

It is beginning to sound like you may have a problem with your SCCM (Steering Column Control Module). Here is a post with some detailed diagnostic information: Clicky click®

Oh boy... Wait but that post is only for wipers, what about my lights? All too confusing :/ so many linkages between all these malfunctions I'm beginning to lose it lol

I believe all of the steering column stalk switches process through the SCCM. For example the way the turn signals work is when you signal left or right the turn signal switch sends a digital signal to the SCCM. The SCCM then sends a command to the Central Electronic Control Module via CAN bus message then the CECM flashes the turn signal lamps as required.

So this unit is responsible for:

Instrument cluster lights
Wipers
Hazard lights and or security system
AND any potential other outside light warnings I got? I thought the BCM was simply responsible for that, because I have no issues with turn signals, just hazard light taking over my flashers sometimes

Hello there, for nearly half a year I have been trying to fix this problem and I recently came across your Audizine post.

I have retrofitted my tail lights on an Audi S5 2009, to LEDs, but I think while I was coding on VCDS I must have done something wrong. Since then the rear turn signals and Hazard lights hyper flash on the dashboard and dont ever work.

I have since, tried everything, from putting load resistors to getting someone to recheck the coding, and even going back to my halogen lights, but still wont work.

VCDS shows that there is a body control module fault.

Just now Im starting to think, could I have damaged the BCM and that is why it is hyperflashing?

Thank you

CCM or BCM in control of side view mirrors? just discovered my passanger side mirror is not working any more, door has power still. Another thing just started happening, the interior lights are not coming on when any door opens, the foot well lights and splash lights still come on, just the overheads are not coming on. they work when turned to on position.
