LED bulbs for Leon Cupra 2010 (bixenon headlights)

[drcain]

Hi guys,

I was wondering if anyone has already good experience exchanging some or all of your bulbs to LED bulbs in Leon Cupra R 2010 with bi-xenon headlights - the ones with crappy bulb DRL.

I'm specially interested in DRL P21W equivalent, that is not "smoking hot", puts out around 460 lm or more and of course is canbus friendly..

Hints / links on proven other bulbs are welcome too

Thanks.

You will need 3 501 style leds, and 4 festoons for the sunvisor and rear. festoons dont work in the number plate, as they give canbus errors. Also email,and check the order, as some Leons, use a festoon and two 501s in the main front roof light, but on the cupra R its 3 501s in the main light.

are the interior lights connected to the canbus system?

 

[LeonCR]

no idea but all mine are canbus and work really well

 

[Jarre]

might get a set of non canbus leds to try. I can't see them being connected to the canbus system tbh.

It was just a pack of bulbs mate so used what they sent

@LeonCR: thanks for the links mate I'll check them to see if I can get them around here or if I have to order them from the UK

I'm only missing lumen output on those bulbs - any idea what it is? I don't want to use too bright ones but also not too dim ones.. - especially in the headlights.

OK, you made your point Thanks for the pictures

Those are very nice, LeonCR. I'd definitely go for the MTEC sidelights for the very bright white. I got Osram Cool Blue Intense ones only because MTEC isn't available here and I don't really have a method of online payment for eBay and such.

This is what it looks like compared to the stock bulbs:

And together:

I have the regular head light units and they'll look even better on bi-xenon ones. The Osrams are regular halogen ones, though, and therefore much weaker than HIDs (even the brightest of the halogen bulbs), but I've had very bad canbus experience with LEDs which is why I avoided them in the first place. I'm going to look into finding an online payment method so I can order the MTEC LED ones.

@LeonCR they haven't given you ANY sort of errors ever since you installed them, right? And they are W5W, correct?

 

[drcain]

@TarekElsakka: no, you can clearly see in the second picture from LeonCR that small W5W bulbs are OFF. These are the P21W bulbs that go to DRLs..

 

[LeonCR]

No errors at all with these bulbs

Guys, could you help with taking out the DRL bulb? I've been trying in the past hour with no result and this is the only post I found about DRLs.

Hello everyone,
I have a 2011 Cupra to which I fitted some LED number plate lights. These have worked well for about a year but have just gone off with a message on the display to check them. I put the OEM light back in but this did not fix the problem.
Any suggestions as to what I can do to get the lights working?
Cheers

If you get bulbs and they give errors you can switch the errors off using VCDS if you have access to it or live close to someone who does.

If you get bulbs and they give errors you can switch the errors off using VCDS if you have access to it or live close to someone who does.

Not on the 2010+ cars you can't because getting the bulb warning light to go out involves messing around with the infamous byte 18 which is undocumented so it's a complete minefield with no guarantee of success. And by messing with that byte you also risk not being able to get your car back to it's default configuration if it all goes wrong because the original value of byte 18 is masked with zeros so you have no idea what original value to set it back to.

The only sure way to disable the cold and warm diagnostic checks for individual bulbs is with VCP which is able to directly edit each of the individual EPROM bits for the lighting system in the BCM. This is something that VCDS cannot do.

You can of course try CANBUS "error free" bulbs but more often than not these also cause intermittent bulb failure warnings. It's all just down to trial and error which may end up with you getting lucky. Even trying the same CANBUS bulbs on your car that someone else reports as working successfully on their car is no guarantee they will work because each car seems to have slightly different tolerances where one car may accept a CANBUS LED bulb without throwing any errors but another seemingly identical car may not.
