Hi guys, I'm after a little help please!

I hope to fit a HID kit and the LED tail light clusters from the L&K to my 2011 MkII Superb CR140 SE.

I know both of these will trigger the 'bulb-out' warning on the dash.

I understand fitting the CANBUS-friendly HID kits can cause issues with wiper motors and other electrical gremlins further down the line so I would prefer to fit the non-CANBUS kit and disable the cold-start diagnostics.

But, with regard to the tail lights I'd prefer not to have to fit resistors to them and instead just disable the cold-start diagnostics completely.

Does anyone with VCDS know if this is possible?

Many thanks!

From memory I think the cold diagnostics are divided up into about 6 sections dealing different lights, so yes you should be able to turn off the relevant ones or all of them.

Brilliant, thanks Trundlenut, a local guy has very kindly offered to help me out with his VCDS so I just wanted to arm myself with as much info as possible so that I don't take up too much of his time!

From what I recall the Brimma-mobile has LED rear clusters. I don't remember him having to do anything in VCDS to get them to work without issue.

I don't think you're disabling cold diag on the HIDs either. HIDs draw less power, and so will throw up a bulb warning. It seems that the system is looking for a specific resistance, instead of open circuit. (The same happens when you put the wrong blub in the stop/tail on the rear: it works, but throws the warning up.)

Do they have built in resistors?

You'd have to ask Brimma. I know they were made by Dectane, who apparently know a thing or two about lights.

IIRC they did a little dance on Brimmas on ignition on so diagnostics were still turned on

Yes, I remember that thread. He posted a video of the cold-start diagnostics at night and you could see the CANBUS checking each of the functions which resulted in a very, very brief flash of the LED's.

The Dectane LED clusters have resistors built-in.

The tail lights I have just ordered are the genuine Skoda clusters which are not fitted with resisitors. The Superb L&K is instead coded to work with rear LED's. I could just use VCDS to repliacte the L&K coding but no one has successfully managed it yet. See this thread...

SuperSkoda sell the LED tail lights and make specifc reference to them triggering the bulb-failure warning light...

Are you saying that by disabling / turning off the cold-start diagnostics I will still get the bulb-failure warning if I fit the rear LED's (no resistors) and non-CANBUS friendly HID's?

Here is Brimma's thread...

...and the video...

I imagine they are going to need the byte 18 code changed… good look with that though as it is not recommended to mess around with byte 18 codes as the true code is hidden behind the “00” mask.

This is why I'd rather just turn off the cold-start diagnostics completely.

Can anyone confirm if this is possible on the Superb?

If not I'll go for something like this...
