Tesla Model S Headlight repair DIY. Where to get parts in Australia?

[gizmonty]

The left headlight on my 2014 Model S has started to play up. It goes out a couple of minutes after starting the car. I booked it in for service but Tesla have quoted $1700, presumably to just replace the entire headlight assembly.

From my reading it sounds like this should be a pretty simple repair and most likely requires just replacement of the HID bulb. Apparently it can sometimes be the ballast, but my problem sounds most consistent with a bulb problem. It looks well within my abilities to do this myself from watching a few youtube videos, I just need to get the correct bulb but am not sure what the best source for this would be in Australia.

I've found this online - D3S Xenon 35W HID Kit (Pair)

Would that do the job? Would it match the original, or require me to do both sides. Does anyone have any insights or experience they can share?

If your bulbs are Australian original, they are likely to be 25W HIDs. May I suggest you have a look at Does anyone recognise this headlight plug?

My experience with aged bulbs is do them both as the new one is usually brighter or whiter. Be careful not to ‘upgrade’ the wattage without adding a relay as you‘ll damage things.

I bought the D8S globes for my 2014 Model S from Tesla and they were $175 each. I fitted them myself, but Tesla will fit them for you. I was quoted similar or higher price from other sources.
The reason Australian Model S use a different globe is because they had to be de-rated from 50W to 25W to pass ADRs.
The D8S is the 25W version of the 50W D3S but the mounting surface of the globe is keyed to prevent you from fitting a D3S.
Ask me how I know!?
Most likely Tesla are quoting you for a headlight replacement assuming worst case scenario, but the price will lower when they find the new globe fixes the problem.
Get both done at the same time, my RH globe went before Xmas and the LH about 2 weeks ago.
P.s. Anyone want to by a pair of D3S globes?🤷🏻‍♂️
P.P.S Unless you are a big DIY lover get Tesla to replace them, you need to remove the front wheel and the front inner wing liner to get to the back of the headlight.

So this is why our low beam is so poor, how annoying. What a shame you can't just fit the DS3 globes.
And a big 'what the?' with the ordeal to change a damn headlight, what was Tesla thinking.

So would these do the trick? OSRAM D8S XENARC XENON Bulb 25W OEM 66548 VW Audi Tesla Amarok
They state Tesla on the page. $99 a piece seems good, and my DIY skills are usually pretty slick (my free time is the limiting factor).
If I’m feeling patient I found another cheaper (but much slower) option. https://m.aliexpress.com/i/4001263951409.html

Yes, that’s them and for a good discount.

Thanks again Meloccom. I will report back with my experience.

I had a Model S headlight assembly replaced under warranty, because the LED daytime running lights failed. Was told by service anecdotally that these LED strips (or the board that drives them) are usually the part that fails first, requiring swapping the whole unit. But since my car is now well out of warranty, I'm always interested in picking up DIY tips

Now that it's Monday and I've been able to hear back from Tesla on the app, they have revised the estimate to $240 parts and labour. Not worth the DIY effort to avoid that price, so as long as there are no surprises I think my brief exploration into the world of headlight replacement is over.

You could just install the refresh LED headlights (“plug and play” using a switch box Bacila) from that are significantly better than the 25W HID. I found used headlamps with intact mounts via eBay/UK.

Or upgrade the ballast and go to 35W HID and see what you‘be been missing! There are options to also improve the lens if you are trying to get the most out of them.

I think the 25’s were a safety hazard especially driving on country roads.
