I'm getting the following error and the independent VAG garage with ODIS cannot reset. They say the central electrics module is damaged and needs replacing at £462 plus VAT, then recoding

 

Can anyone tell me the the part number for this module please? I want to see if I can get a used module

 

Also, where is it and how easy is it to fit?

 

 

Wat error?

 

The Central Electrics module is the BCM.

There r different versions of it.

Wat is the part number of ur current BCM?

@pab567 to the rescue?  By central electrics unit is that the headunit in the glovebox or are they referring to another unit?  If it's the headunit then Pab will be able to help you with a more affordable solution.

@jonesi100 pls share VIN and put error details, e.g VCDS scan

VIN is TMBKH7NP4H7506028 Skoda Superb MKIII 2017

Thanks you so much.  So I just need item 1 which is 5Q0 937 084 CE .  Should i remove it first to double check?

@jonesi100 - 

U've triggered Component Protection on both the Central Electrics (09) and Gateway (17) modules - that means something has been added to the car that wasn't originally fitted from factory, or something has been removed from the car.

 

What did u change?

 

U need to remove the Component Protection by visiting a dealer to take care of it.

I’ve not changed anything the BCM is faulty the dealer thinks

Can anyone tell me there the BCM module is located on my MKIII Skoda Superb?  Is it under the steering wheel or behind the glove box?  Also does anyone have any instructions on how to access it?  I’ve seem some YouTube videos of earlier models showing that it’s on the drivers side and the carpet trim plus other plastic trims need to be removed to gain access. Any help or advice would be really appreciated. Thanks in advance.

On RHD Superb, it's on the passenger side, below the glovebox, left of the footwell.

 

2018 Skoda Superb Se L 2.0tdi 150hp

Hello did you ever find a solution. Have the exact same issue/faults. Car was working great and went out in morning and turned on ignition. All interior lights including footwell and led along dash and door not working and no heated seats. Car still starts drives etc. Exact same codes as above and component protection on central electronics and gateway. I connected to odis and tried clearing component protection etc. Does everything but odis comes back with a error.

Component protection central electronics module failed.

Faith error message

FAZ9484E-Fehler:checksum-1 is incorrect

I tried to code module and comes back with same error.

I check info in module and doesn't show a vin etc. Even though I coded it. So I can only presume its corrupt and no longer holding information.

Am I correct in thinking this? Will I need a replacement?

What's my best bet buying a used 1 and trying to recode it or just taking to dealer and being done with it?

Any help would be great! Thanks

Best Regards

Scott

Yes, bcm needs to be replaced. You need Odis online

Hello thanks very much for taking time to get back to me. So when I was connected via odis using 6154a and gecko online the checksum error is what came back. Because of this I checked the bcm for vin and it says null. I presume because vin says null and component protection is active I'm essentially stuck in a loop. Would odis engineering offline allow me to manually enter vin even though cp is active or is the first step always cp removal first as the bcm is locked out?

Would it make any difference if it was removed from car and I use something like mpps v18 breakout with odis?

Or should I buy used bcm with cp deactivated that matches my origional and change vin? But I also assume vin change can only be done away from car with obd breakout as cp will be activated if connected to car without vin change first.

Again thanks for your time its much appreciated.

With your current BCM you can't do anything.

You need used(legal) or new BCM, the only you need to get backup from your current bcm in case you want to install newer bcm(I recommend this way), because online won't give you coding/adaptations for newer version. If you install same BCM, you can do online coding and Odis will restore coding/adaptations.

e.g. I installed FL BCM 5Q0937084EC into my 2015 Superb. You can buy it from Aliexpress(they're ok and legal), I believe it would be cheapest way. Because there a big chance to buy used one with same issue or stolen in bad scenario.

And after CP off don't forget to assign all keys again from special functions in ODIS-S

Thanks again for all your help. So mines is 5Q0937084CQ which is on the high end already. Think it may be simpler to just replace with same bcm model.

So if I buy one from alliexpress are they generally used or new? I had a look and most don't say anything. I'm assuming if it's from eBay or alliexpress they will more than likely have a vin already on them.

First time doing all of this so just Nedd a quick rundown.

If buy from alliexpress or used from ebay. I can't plug into car as I assume if vin doesn't match it would activate cp if not already activated.

So give me a quick rundown from buying it to getting it in car. Do I have to run odis without it plugged in car? Or do I Need to edit eeprom with the likes of CH341A?

Just a little confused on how to start the process without locking it. Most things I read say say you need to reset to blank ie virginise it first. Or something along those lines. As a said first time doing this. Don't want to buy a bcm then need to get another and another because I keep locking them up. Thanks again. Still don't know why the origional went bokers!

Don't think about VIN in BCM

As I said previously, you need new or used BCM

1. Disconnect Car battery

2. Replace BCM

3. CP will activate whenever it's new or used

4. CP off

5. Immo adaptation (all your keys)

6. Restore coding

7. Done!

OK thanks for the quick run down. Puts my mind at ease with the process. As a said first time doing it. So over thinking it a bit!

I've ordered a used bcm that matches my my car. I will let you know how I get on over the next week or so. Hopefully all goes well.

Thanks again.

Hello again. So got used bcm delivered today. Was pain in the butt removing old one but got there! Lol So done what you said. And everything went well. All comfort features are back interior lighting etc. Car starts and drives. 0 faults. But I have only one issue Keyfob lock and unlock not working from fob buttons. I also have keyless entry that I think may also not be working as I can normally close door touch little sensor on door handle and it would lock and then unlock when I try to open door. Was trying to find these in odis but was struggling exactly where? Was trying to do it while I still had geko access and my laptop started having a moment and battery started going low so didn't get to to do it. Hoping to fix it tomorrow Did it maybe not authorised it because of certain geko access?

I used 10min cp/immo + svm

Also tried doing it with obdeleven but yet again struggled to find it.

So again thanks very much for your help. Great to have all the features back after like 5-6 months since bcm started failing. Any further help would be fantastic.

Not to fusesed about keyless lock and entry although it would be nice to have everything working again. Just crucial I get fobs to lock unlock again.

So tried everything to get it all working a couple times throughout the day. There is no key adaption section anywhere in odis from what I can see. Which I think is because its mqb platform. It only shows if keys are adapted and what they are adapted to.

So I took the plunge got geko again. Double checked the bcm by updating via svm again. Ran immo asked how many keys? Entered 2. Held first key to start button. It took a while but found it. Held 2nd key and no matter what it wouldn't find it. It got stuck in a loop just kept asking me to hold 2nd key. So I had to cancel. I only had 4 min immo left. I started again and couldn't risk trying 2 keys again so entered 1 and coded 1 key. It all works keyless and fob buttons everything! Really annoying though as both were coded to immo yesterday but for some reason the fobs didn't work after for locking and unlocking. I replaced battery in the 2nd spare fob yesterday before I started all this as car said it was low. I can only guess the battery is a dud.

Anyway it's all working! I will try recoding spare key again maybe further down the line. I might by another spare or 2 try code them to. I originally had 3 keys but lost 1 in a lake in Poland. Lol That's a whole another story! 🤣🤣

Anyways thanks again. Ive learned a few things in this process and your shared info was helpful in sorting this out. Super appreciated!

Sorry to jump onto this thread but I am having the exact same issues, I (Stupidly) replaced my boot lights with some cheap Chinese LEDs and a couple of weeks the MFD and Headunit go dark when the car starts and all the interior lights have stopped working. Ive taken it to a lack Skoda specialist who plugged it and tried everything, including checksum etc.

He has said that the module needs replacing and will be around £700-£800 for a new one fitted, is this about right? Is there any other avenues I could go down before forking this out such as a 2nd hand module, he did say that it doesn't tend to work with a 2nd hand one as it needs to be an exact one, is this also correct?

Thanks for any help, I just don't have that kind of money to put into the car atm!

It's the bcm module. It seems to be a common fault. It maybe the lights that have upset it but can't say for sure. Possibly just a coincidence. My Superb was working perfect. Came out in morning and all lights etc won't work dim dash Dim infotainment. This happens when component protection is activated. It locks the comfort features but car generally still starts and drives etc.The bcm had gotten upset by communication error or hardware fault. Could be a short or if you have alternator or battery issuesI think it may have been my alternator thats caused a power surge on its way out. Some have reported condensation or liquid damage from air filter box I know some have had issues with loom on drivers side door cables bursting/ puliing apart between car body and door.

In most cases the bcm will need replaced. Either new or used is fine. It's easiest if it's from the exact same car with the exact same features. The bcm has a model number and firmware number. You need to match all of this. I would check for some of the issues that may cause component protection to be activated prior to fitting a replacement.

You need to remove glovebox and glovebox frame from dash to access it properly.

I have a 2018 skoda superb SE L 2.0tdi with almost every feature available so I needed the same model or something higher. I found the exact model and firmware. But wasn't from a superb. It was a tiguan. Which still works perfectly.

Now I bought mine from these guys https://www.ebay.co.uk/str/nirroltdvwaudicarparts?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=MxuehGllTEi&sssrc=3418065&ssuid=6XrwZXGBS82&widget_ver=artemis&media=COPY

Was an absolute bargain for £60 delivered but your taking a bit of a gamble for a used one as it may already have issues. I got lucky. But I was willing to do this as I already had the diagnostic tool to do this on my own. But It's not just the tool and software. You need to pay for a geko online slot to access vw/skoda servers.

When you fit new bcm. Component protection will be activated again. My old bcm even when connected to skoda servers wouldn't allow me to clear component protection as I presume something become corrupt and it would always fail. Hopefully with replacement bcm you can get component protection deactivated then you can do a svm update so bcm matches your cars adaptations etc and also immo. You need to re pair all keys to car 1 after the other. The 1st 10 minutes connected to skoda servers will allow you to do this. But it's a little stressful and may take 2 online session to safely get it all done.

I would say it takes a little degree of understanding the software and what each part does. If it all seems like too much I would just pay the £800 and be done. Buying the tool and software alone is a big risk as they are all clones not entirely legal what so ever and risk of further damage. But it is possible to do.

Another option by the used bcm convince dealer to recode most will not want to touch it unless new module provided by them. Or find someone who offers vag coding service either in person always best or online ie pass through but still requires a tool and giving someone you don't know full access to your laptop etc if you go this route I recommend running a virtual machine.

So again its not simple process but can be done. If your someone who messes around with your car and wants to add new features etc then do it yourself and figure it all out if not just get replaced from dealer.

If you need anymore detailed info I will help if I can.

But I would not recommend this route to the average person.

Hope this helps you understand it a little more.
