Hi all

 

Got the airbag fault lamp few days ago and after the diagnostic the fault was located in the drivers side airbag (inside the drivers door?).

I have read some post on the forum and checked the connections under driver seat without any luck.

Want to replace the faulty airbag with a "dummy", socalled resistor fix.

 

Havent found this issue for a 2007 Skoda Octavia II L&K edition, and hope someone can help me with this process step by step?

My main issue is datasheet/pictures of the airbag cabling, so i know where to implement the resistor.

And if 2.2 ohm is the right size for this issue.

 

Im new here so just tell me if any else information or pictures are needed to ease the assistance.

 

Thanks!

Nobody ? 

I doubt many people have done this nor would I suggest anyone remove a safety device for road use.

 

I've seen many posts about VW cars using a 2.2ohm resistor so I'd be surprised if a Skoda expected anything different. You can get access to the official Skoda wiring diagrams though erwin for a small fee https://erwin.skoda-auto.cz

 

Personally, I'd spend some time checking the wiring from the airbag controller to the airbag and see if it's possible to repair this rather than bodge it. If there is a break in the wiring and you fit the resistor on the wrong side of it, you'll still have the same problem

I put the value of the life of the driver at more than a 10p resistor bodge.

first off I would suggest you find exactly where the fault is.

 

Sensor in the door - resistor fix won't fix that

Under the seat - soldering the wires will be better than the resistor fix and you still have a working airbag

Even if the fault shows for under the seat a fault with the wiring from the module to the seat won't be fixed by the resistor.

It's probably the side airbag in the side of the seat. The cause is the yellow plug under the seat. Even if it looks ok it will have a bad connection in it. 

 

Simply cut the plug out and solder the wires together under the seat (disconnect the battery). This will in all probability fix the fault. However even when fixed, the airbag light will remain on until cleared with VCDS. 

 

All the above is no more of a faff than sourcing and connecting a resistor.

Is there a fairly easy way to check if the problem is actually that yellow connector, or is the easiest approach to just go ahead and  cut-and-solder?

Short answer, no. I lived with this problem for quite a few years and even had the airbag replaced which included a new connector. Finally got fed up and did the cut and solder, solved it, no problems for the last few years. Seems a few other car brands had the same problem besides VAG.

Back again

After replacing the yellow connector with a more permanent (though not soldering) version, I still did not get rid of the warning light.

 

Yesterday I had the car at a mechanic for the biannual ("MoT"?) technical control, and they think there must be an actual airbag fault. I.e. I would have to change the airbag.

 

So, I am starting to consider the "resistor fix" that was the start of the present topic/thread.

 

My plan is now:

I disconnect the battery, and then disconnect the yellow connector (or rather, my replacement for it) and isolate the the two wires between the yellow connector and the side airbag. Then I fit a 2,2 ohm resistor between the two wires leading from the yellow connector to the control unit. 

 

I may not be succesful, but I can't see any major hickup I could do either.

 

Am I missing something?

You might as well grease the brake discs while you're at it.

I'll consider your advice.

 

As for the airbag I assume it hasn't been working ever since that warning light first lit up a few months ago. Turning off the warning light will not make the vehicle less safe.

There is another connector tucked right up under the seat squab, before resorting to the resistor bodge (I was also at that point) I would remove the seat after you have disconnected the yellow connector, its only 4 bolts, take it off, invert it on a clean or covered bench and all will be revealed.

 

In my case the yellow connector was a red herring that cost me a hell of a lot of time.

I was short on time, so I did this:

 

Universal Fits for Skoda Octavia Airbag Bridging/Resistor+Advice | eBay

 

It worked. But admittedly I still don't have a functional side airbag.

 

I was told that an alternative approach would be buying an entire seat from a scrapped car. Something I might do when the weather gets warmer. I see they sell at aroun 100 GBP.

Welcome to the forum.... but come on dude, youre due a darwin award if you think thats the solution to a safety system that could save your life.... bodge it up just to get rid of the warning lamp.

There is also the legal side to consider, your insurance company may refuse personal injury cover if you drive with disabled/inop safety features and make a claim.

7 year wait to get a welcome to the forum! 😆
