THE SLR alternator : the story

I apologise for taking my time and for ghosting the IG, but I’m starting an archival fashion side-venture. It was more time-consuming than expected. Setting up AI agents to scrape the internet 24/7, bid for me and on top of that set bidding limitations based on season/collection, condition and how limited the piece is. If you’re interested in archival Hedi Slimane pieces - I’m your person. Technically, I can find you any archival piece you want, but let’s say I specialise in Hedi Slimane’s world. How did that start? One day I woke up and realised I have adult-adult money and I only want to wear Saint Laurent by Hedi Slimane ( I understand this may not be the most relatable thing I could say on here lol ). In the last three weeks, I’ve donated 90% of my wardrobe and I decided to turn this obsession into something bigger than just my own indulgence. I already have a curated selection of pieces that will sell for around 90-100k combined. And it took me three weeks lmao. For the people who ask “what do you do” - the right question is “how?”. This is how - obsession and also autism probably lol - three weeks ago this side-venture didn’t even exist. I studied fashion and I work as a menswear designer and I know what I’m looking at - that’s the disclaimer here. My eyes are like fashion scanners.

On 11.12.2025,

we took the SLR out for a mountainous drive. As we reached the peak, we stopped for a quick photo opportunity with both my 720S and the SLR. This is when the first alternator failure error message popped up on the dash. Been there, done that in 2023. PTSD and all sorts of mixed feelings began to hit left and right. The car was error-free for two whole years. And on top of that, this was still the same and only issue we’ve ever had with it - the alternator.

Luckily, while being unlucky, this happened at a large parking lot. The SLR being brake-by-wire, the only option was to call in a tow truck. Then we took it to Mercedes-Benz. After one week at MB, they called us to come and pick it up because “they don’t feel like it.” Again, we only took it there after they confirmed they could in fact do the repair. We don’t drive the SLR around on a tow truck for the lolz, just want to clarify this once again. We called, they said, “Sure, bring it in,” then they called us to pick it up. That’s it.

We don’t take the cars to the official dealerships - we never do that. But this being the SLR, and with the repeating alternator issue, getting it diagnosed in-house was the preferred course of action. That was the main reason we took it to MB. They declined to diagnose it. They just didn’t want to touch it at all, which was probably for the best for the SLR (not for them - see the previous post).

We took the SLR to one of the trusted independent shops where we usually take the exotics. They failed to source the alternator. It’s a very big shop, and they’re very busy with car events too, but again - that doesn’t justify wasting a whole month just to say, “We can’t find it.” It took me a couple of hours to realise we were fucked. And while I knew the whole time we were fucked, I also wanted to see how seriously they would take the repair. I got my answer, but it took a month. Mind you, they were very excited to have the opportunity to work on an SLR. How did that turn out?! So, we had to take the SLR once again. It was already February, btw.

The SLR was taken to another independent shop. We knew the owner would dedicate the attention this car deserves. The reason why the SLR wasn’t taken to this shop in the first place is because, like I said, the previous shop insisted that they wanted to work on it and were beyond excited to do so. But sourcing the OEM alternator was still impossible, and we hit the wall for one final time. We got a Bosch alternator. Here’s the thing - some insider info - the alternators globally built after COVID are of lower quality and don’t last long. So, the alternator had to be new/unused and built before COVID. That alone took two weeks to source.

In the meantime, the SLR went through an in-depth inspection. The car is in overall perfect shape. The famous list of repairs that needed to be done - the one that made the news under Ed’s ownership - was revisited. Nothing was found to require attention at the moment. I was very pleased to hear that. The list was blown out of proportion, but it’s not wrong. So yeah, nothing new that I wasn’t aware of was discovered.

I don’t mind using the names of shops and publicly saying, “They did us wrong,” I just don’t want this to be the focus of what I do. I do have a blacklist of places I will never take the cars to - this list exists. I don’t want finger-pointing to be the contribution of theSLRgirl; therefore, I refrain from stirring drama and name-dropping.

This was my first one-on-one with the architecture of the SLR. I’ve read about it, I’ve seen it in photos/videos, but it was new to me to see it with my own eyes. It was built by McLaren, and the second you remove the underbody covers, your reaction is: “Damn, that’s a McLaren,” especially if you’ve been under a Super Series one. It’s so neat and organised that it invites you to explore it further. It even invites you to work on it! Not only that, it gives you the confidence to do it. It’s so well designed and organised that it doesn’t allow room for errors. It was my first time seeing anything like this, and it’ll probably be my last.

Another feeling it evoked when I was under it was that it’s a bespoke precision machine built for extreme forces. I always knew that, but seeing all those elements taken straight from the highest levels of motorsport and implemented into a road-legal super-hypercar cemented it as possibly one of the most intentional cars out there.

The Murci was built in the same timeframe, and it’s like a horse carriage next to the SLR. And I love the Murci - it’s a very special car, and I even have a Murci-dedicated tattoo on my arm - but the SLR was soooo ahead of everything around it. Still is. (I also have an SLR-dedicated tattoo lol.) It’s superior to the Carrera GT and Enzo as well. It’s not only the best 2000s unicorn in terms of reliability and running costs, it’s also the most unique. Like, who’s even the target? We all know who the target of the Enzo is, or the Murci, or the CGT… but who was the SLR built for?! And it gets deeper. I believe the SLR was built for the sake of it - just because they could, almost as a monument, as a culmination of peak motorsport know-how and whatever was in the air in the 2000s. It stands alone in no man’s land.

In the next post, I’ll explore the technical side of the repair, I'll include the recall documents one more time, and I'll discuss possible solutions to the alternator issue.
