Hello lads
Which bulbs need to be canbus error free, all of them, exterior only ??

None of them, there is no such thing as canbus bulbs or canbus bulb errors, despite what ebay sellers think.

The bulb warning is a function of the bulb resistance and so the lower the LED resistance (higher wattage draw) the less likely to get an error, unfortunately all LEDs draw less power than originals so it is a case of finding where the system draws the line.

All of external bulbs throw broken bulb warning if the resistance is too high.
All of the interior bulbs put an error code in the control modules (boot, glovebox, roof console etc...) but they are not a nuisance unless scanning with VCDS.

Nicely put Snap.
Much better said and many fewer words than I did it in.

+1. Far from cheap, but great bulbs. I have four in the ceiling of mine. They're brilliant.

Cheers mate, do they still work with the ambient lighting function ?? Dimmable

I believe so. They fade in and out too. Clean white light. No bluey hue.

Word of warning.
Do not fall for the Ebay myths of canbus free LED lights.

How they work is a resistor in parallel with the LED. This resistor gets rather hot when the light is switched on. Often it is hot enough to melt the solder and the resistor falls of, the LED still works but you then have an error light on the display. Sometimes (happened to me) hot enough that the heat is conducted back along the supply wires and the insulation melts filling the car with an obnoxious smell, the wires can short blowing a fuse if you are lucky.

Trups will sell individual LEDs, but the best way to go is to use his kits. They are little packets, labelled and ready to fit. He gives you a warranty but I doubt that you will need that. I have replaced most of my lights with his LEDs without problem for over a year.
The only ones that I have not replaced are my reversing and rear fog lights.
