Wat is the "bulb monitoring option" u referring to?

 

If u mean the CANBUS monitoring that tells u if a bulb is faulty - yes it does.

In fact most Skoda models do that.

Never understood why people call it canbus error free/monitoring. There is no canbus involved at all, its simply open circuit and current monitoring. Sending a halogen or xenon bulb a canbus signal would mean absolutely nothing and wouldnt do anything.

being pedantic so feel free to ignore me

Yes you are correct in that the Lighting Control Module will likely monitor OC & Current however  the LCM will then communicate with the rest of the Control Modules and the Primary Module using CANBUS

Well that's what I think anyways

I would think it will drastically reduce the diode life, as all the fan is doing is circulating hot air inside the headlamp unit. 

 

In theory yes, hence why time will tell. 🙂

Either it will b fine, or it will fail miserably.

If we are being pedantic, the 55/4B multi function control module does communicate with all other modules on its network using canbus. But.... when talking to its slave modules (left and right headlight) it uses a different protocol. Then the individual headlight control unit (sub system 20 and 21) these then do the functions including current monitoring and light fault monitoring.

damn it, out pedanted lol


but I think we can agree on why generically its just thought of as CANBUS monitoring ;o)

Errr... What about a marketing argue to let people think this is a high technology product, which therefore has to be sold more expensive?

Egg-jacktly, Gandalf has factory bi-xenon (HID).  All I've done is replaced the xenon bulb with an LED bulb.  Everything is exactly the same, wiring and all.

 

Whilst @Winston_Woof was quick to say this would b a fail, in the very same post, in his quote, it goes on to say it is legal if U already had HID headlights.

 

"If a complete headlamp unit has been replaced with a unit that was manufactured with HID or LED light sources, it must not be failed for ‘Light source and lamp not compatible’ but it must meet all other requirements detailed in section 4 of this manual specific to the type fitted at the time of test."

 

I think you've misunderstood...

 

A headlamp will be type approved for a specific light source. Replacing that light source for any other should cause an MOT fail. This applies to:

- Halogen headlamps with either HID or LED lights fitted

- HID headlamps with either halogen or LED lights fitted

- LED headlamps with either halogen or HID lights fitted

 

However, it does allow for swapping the entire headlamp with type approval for a different technology assuming the other requirements are met.

 

Not that this is particularly relevant to yourself but it could be important for other UK folk

Beause people lack the knowledge, intelligence or energy to ask themselves does this BS I have just read for the Nth time seem plausible.

 

And in the case of so called "Canbus compatible" LED bulbs etc it is complete BS.

 

It serves a purpose in scaring people into the hands of the garages though, my now ex UK neighbour I have known for 40 years, he and I always did our own work on our vehicles including fitting multiple towbars and never used garages, when he bought an Octavia 2 facelift (because he was so impressed with the reliability of my MK1) he paid a small fortune to have the towbar and electrics fitted saying that it was no longer a DIY job because all the electrics were Canbus.

 

I was still driving my hyper reliable MK1 and had no knowledge of or contact with Canbus until I bought an Octavia 2, then I learned that it was simply a comms protocol between modules and had nothing to do with the rear lights, also to my surprise my MK1 had Canbus and I had never even been aware, I fitted my own towbar and electrics for around £100, a fraction of what my neighbour had paid, when I looked he had exactly the same set up with the same switching relay as I had, fear from the BS that he had been fed cost him big time.

Yeah, I think you guys are both right, just that legislation might allow a different degree of action in different places 🙂

Thanks for the clarification there.

 

I'm pretty sure there will b something, somewhere, in the compliance rules here in Oz that will imply this mod is a fail/illegal too.

I mean that the cars electronics monitor the bulbs for failure or possible failure, hiving you early warning. It does my monitoring the current each bulb is drawing and in my cars system it has options different types of bulbs in various locations, for instance in the number plate lamps, I have the options of normal bulbs or LEDS and as LEDS draw far less current then incandescent bulbs, this makes perfect sense that the car needs to know what type of bulb you have fitted where?

 

I was asking because I suspect that your LEDS will draw less power than the xenons would and might throw up the occasional error message.

this scenario I believe they will draw the same current, but will out more light, plus driving the cooling fan. OP should be safe enough

Maybe so, I have not investigated the headlamp settings, only noticed the settings by change on the number plate and just assumed that all important lamps would be monitored similarly. Not knowing of the current drown by either Xenons or LEDs such a role, I just thought it was worthy of a mention in case such a warning was displayed.

the factory xenon bulb is powered by a ballast (8K0 941 597 B), controlled by the light control module (8U0 941 329 version A headlights; 4H0 941 329 version B headlights), which is in turn governed by the AFS Module (3Q0 907 338 - 4B Multi-function module).

The LCMs r sub-systems (slaves) of the AFS module.

the power consumption of the xenon bulb, and the ballast, is rated up to 35W.

the LED bulb takes the place of the xenon, consuming the same power - up to 35W.  given there is no change in power/current drawn, all the systems r happy, and nothing is reported back to the "CANBUS".

LED boot upgrades. Those were the only non-led bulbs from factory.

Pedal and footrest revamped. Pleased with the materials: soft sticky rubber and stainless steel. All fits like a glove, no tools required.

Where did you get the wiring from for those extra boot LED's?

Plug'n'play on the liftback. The saloon/estate has it in a different place.

It seems they are no longer available?

 

I found these - they lack the cables, so I'm not sure if they are a requirement?

For the standard placement behind the rear seats, no cables required. For the trunk/rear hood as MartiniB, I think they are used to extend and install 180' deg from "intended" position?

@naster

haven't info, from what source dealer powered them on MY23 Mk3.FL, on previous MY16, source were closing button illumination wires

 

Oh, I thought I open the caps and reach for the harness and then plug them cables. WIll check later and might take a few shots. Thanks.

Ah ha. I couldn't tell from the photo what model you had.

Mine's an estate & have already upgraded the bulbs in the tailgate lamps but I don't have any lights further back in the boot as shown in the photo - hence my question about the wiring. 

Upgraded the washer tank cap:

 

Bought 2 (also one for my wife's Cupra Formentor) from Ali*** for less than €3.

Fits perfect.
