Hi

Apologies in advance for a bit of a rambling question...

My Fabia SE+ Estate is two weeks old and twice I've had problems with the central locking. Is this is common problem at all? On the first occasion I stopped, switched off, took the key out and got out then opened the boot. But the back doors didn't open. This worried me as the children were in the back and the child locks are on. I pressed the release on the dashboard and nothing happened. The remote did nothing. The key in the door locked and unlocked the driver's door but nothing else. Not sure what happened but it eventually worked and the back doors opened. When I locked the car (can't remember if with the key or the remote) the red light in the door stayed on for 30" indicating a system fault.

Came back 15 mins later and it was all fine - and remained so for a week. Car was in dealer last Saturday to have an accessory fitted and they reset the module as a precaution.

But today it happened again - wife was in the car picking me up. Doors had locked automatically and the engine was left running. After I'd tried the door she remembered about the locking and pressed dashboard buttons a few times but door didn't open so she opened it manually. When we got home she stopped and removed the key but the rear doors wouldn't open again. Dashboard button seemed to lock and unlock the driver's door only; remote button did absolutely nothing. At least I discovered that I can open the rear doors by using the interior handle to unlock then the outside one to open.

Using the key in the lock, the red light acted normally, not showing the fault indication this time.

Again, 5 mins later it seems to be OK.

Is this likely to just be an electronics/software fault, or something mechanical? It'll be going back to the dealer when I get chance, but not sure they can do much with an intermittent fault.

Thanks for any advice you can give

Gary.

Hi Mr Music, I have to press my key fob unlock button twice in quick succession to unlock all doors including the boot. Pressing it once unlocks the drivers door only...but you can of course unlock any door from the inside using the inside handle. So my first question is...are you pressing the key fob correctly in quick succession to unlock all doors? If so, it could be that your key fob is faulty. Possibly the central locking needs to be reset by the dealer or, if you read you manual it can be reset by yourself following the procedure listed. Although unlikely, if you have used your key in the keylock on the drivers door you may have inadvertently upset the central locking settings if you have been experimenting. It can happen.

Ah-ha someone else with problems - I thought it was just me going mad! Picked up a fabia a few weeks ago, and from day one have had intermittent problems with the central locking/key fob (happened about 4 times in 3 weeks so far). Symptoms always the same. I click the locking button on the fob but nothing happens. Try any button, again nothing happens. Leave it for a few minutes (enough to get a brew on anyway) try again, all is fine! Very weird, as if it's re-setting itself. I know the fob is working as the little red light comes on when I click the buttons, so the battery must be ok. I read somewhere that accidentally clicking the buttons can cause a problem, but have been careful to avoid this. All works ok when using the key in the door. The manual is a bit vague but mentions "synchronizing" the fob with the car, but the text doesn't make sense (a poor translation I think). Anyway, the dealer mention it needs to be done by Skoda technicians, and will get around to it soon, as I think it's going to let me down at some point. I would be very interested to see if anyone else has problems, or if it's a known fault? Cheers mateys.

I'm having lots of issues with mine also. Dropped it into the dealer for a look who told me there were no errors and nothing wrong with my car even though when I run VCDS, I get the below errors.

3 Faults Found:

03302 - Response Closing Status of Pasengers Door

008 - Implausible Signal - Intermittent

03303 - Response Closing Status of Left Rear Door

008 - Implausible Signal - Intermittent

03304 - Response Closing Status of Right Rear Door

008 - Implausible Signal - Intermittent

I've had exactly the same problem twice in two months on a 1 year old 1.2 HTP on loan from the dealer until my car is built. After ten minutes it seems to reset itself.

I've not had this issue yet however do have different issues with the central locking. One is that after driving and getting out of the car even if all doors are unlocked the boot remains locked and I have to use the remote or button on console to unlock. Also the windows holding down the unlock button refuse to operate sometimes it won't wind them all down no matter how many times I try holding down unlock which can be really annoying. Once I tried for about 5 mins still wouldn't work so got in car turn ignition and attempted to put all windows down using buttons on drivers door all worked except passenger rear window which refused to go up or down until i removed key and started car again very strange. Even holding key in unlock and lock to reset windows doesn't cure issues.

Hello Fletch - hope you don't mind me asking, but what is "VCDS" that you run? Is it a function on the Fabia itself? I've only had mine a couple of weeks, and still getting used to it, and the manual! Brilliant motor other than this central locking problem though. Mine would not lock again this morning, but did it with the key in the door ok. When I came back 10 mins later, all was back to normal. Very Strange.

It's happened again. The button inside would lock everything fine, (as did the speed sensor) but would unlock only the driver's door. (Actually I'm only assuming that, but of course it may have remained locked and only opened when I pulled the handle). Key-fob would do absolutely nothing. Using the outside lock would again lock everything but only unlock the driver's door. Then, suddenly, it all started working again.

What worries me about this is what might happen in an accident. The doors are supposed to unlock if the airbag is deployed, but what if the central locking is having one of its sulks? Would the doors then remain locked? No way to test, of course!

Not sure what Skoda can do as it's an intermittent fault. Resetting the system after its first 'blip' didn't make any difference. Does the software log these sort of things? It looks like it's not a common fault, or else loads of people would mention it - but neither is mine an isolated incident.

Will talk to dealer next week...

I have a similar intermittant issue, but alot more intermitant than ours. (Its happened twice in 6 months) I can usually open the doors no problem so Im not panicint at the moment, but your issue, aspecially with the kids in the car would worry me a bit more...

I too wondered about the "unlocking in an accident" schenario while reading your first comment. The first thing a car is suposed to do is unlock the doors, then trigger the air bag... I'm assuming is would use the same mechanism it normaly uses to unlock the doors. So in theory this could happen and the doors would remain locked. Bit of a worry even if a very rare chance.

Link to my issue, (But not much help to you)

there is an issue with some central locking units went into skoda yesterday regarding a rattle and they run a vcds as standard and found errors with central locking, they have had to order some Solenoids.

Hi All!

 

I found this topic when I searched information about problems with central locking. In my car the problem happened after BCM module replacement (cruise control installation). After a few weeks after replace factory module 6R7937085D to 6R7937087H I saw first problem with the central locking in my Skoda Fabia (prod. 02.2011).

 

From time to time (e.g. once a week) central locking doesnt unlock some doors: rear right, front right, tailgate or all of this doors at the same time. The problem with unlocking was solved every time itself - automatically after over a dozen minutes. After the problem in BCM module is logging some fail codes, depends which doors were problem with unlocked. Below is print for diagnostic scan:

Central electronics
Part #: 6R7937087H
Coding: 7C980B9808210048002000002C0B088000C0400F600000000000 (hex)
Component: PQ25 BCM
Fault codes:
03437 Control Circuit for Motor for Central Locking, safe
03301 Feedback Locked-Position Drivers-Door
03302 Feedback Locked-Position Passengers-Door
03303 Feedback Locked-Position rear-left
03304 Feedback Locked-Position rear-right

After long researching I found solution for this problem. The problem is known in central knowledge base in Skoda services and it was registered in TPI document no 2026500/2 from 2011-07-14.

 

In some BCM modules which were produced before 45 week in 2011 such errors can happen. In the TPI document Skoda describes how to fix this problem. Fixing the problem requires mounting two additional parts (TVS diode) on the cable harness (only) in driver's door. Those two transils is protecting from voltage spikes induced on wires and resolves the problem with failures in central locking circuit.

 

Skoda did makes repair kit to permanently fixing the problem: 5J0 971 658. In one car you have two kits (one box contains one transil). The BCM modules which were produced after 45 week of 2011 was modified and problems with the errors in central locking circuit shouldn't happen. Probably the new BCM modules which produced after the date contains those transils in the box and central locking works fine. Detail about the repair (where and how to mount the diodes) you will find in the TPI document.
