BMW G80 G81 G82 G83 M3 & M4 - Genuine CS Power Upgrade Now Available at Eurowerke

At Eurowerke, we’re always looking for ways to deliver real, measurable performance gains for BMW owners without compromising reliability. For BMW G80 M3, G81 M3 Touring, G82 M4, and G83 M4 Convertible owners, we’re proud to now offer something truly special - the genuine factory BMW ‘CS’ software calibration.

This isn’t an aftermarket tune or generic flash. It’s the same official BMW engine software found in the limited-edition M3 CS and M4 CS, now available exclusively for your G80, G81, G82, or G83 M3 & M4 at Eurowerke in Sydney. This upgrade delivers a substantial increase in power and torque while retaining full OEM integration, everyday drivability, and BMW factory reliability.

Beyond the ECU - Full System Recalibration

In addition to the factory ECU software upgrade, our BMW CS Power Upgrade also recalibrates several other critical systems for a truly transformed drive:

TCU (Transmission Control Unit) - for sharper, quicker, and more precise gear shifts.
DSC (Dynamic Stability Control) - for refined traction control and predictable handling at the limit.
VDP (Vertical Dynamics Platform) - optimised adaptive suspension tuning for improved chassis balance.
EPS (Electronic Power Steering) - enhanced steering feel, weight, and precision.

These updates bring your BMW G80 M3, G81 M3 Touring, G82 M4, or G83 M4 Convertible closer to the dynamic performance of the factory M3 CS or M4 CS, creating a more connected, engaging, and confidence-inspiring drive - without leaving BMW factory spec.

What is the BMW CS Software Calibration?

The BMW M3 CS and M4 CS are the ultimate all-round performance models of their respective ranges - blending track-capable hardware and software with everyday usability.

At the heart of the CS’s improvements is its factory ECU software - the same programming now available for BMW G80/G81/G82/G83 M3 & M4 models at Eurowerke. This is genuine BMW engineering, developed and validated by the manufacturer, ensuring full compatibility with all original systems.

Performance Gains - BMW M3 CS Software Upgrade

On our in-house dyno, the results speak for themselves:

Stock Output: 363 rwkW / 709 Nm
CS Upgrade: 382 rwkW / 710 Nm
Gains: +19 rwkW / +1 Nm
Note: Reference graph is stating power at the hubs

These gains mean noticeably stronger acceleration, more responsive mid-range pull, and an overall sharper driving experience - whether on Sydney’s roads or at the track.

Note: Dyno results are based on our in-house testing - actual figures may vary slightly between vehicles due to individual tolerances and conditions.

Why Choose a Genuine BMW Upgrade Over an Aftermarket Flash Tune?

While aftermarket tuning can deliver big numbers, it often comes with trade-offs. With the BMW CS factory upgrade, you benefit from:

OEM reliability - developed by BMW engineers for long-term durability.
Seamless integration - fully compatible with drive modes, safety systems, and electronics.
Consistent performance - no issues with cold starts, extreme heat, or daily use.

It’s the ideal choice for BMW G80/G81/G82/G83 M3 & M4 owners wanting a performance boost without the risks of non-factory software.

A night to remember, S58 Tech Night at EuroWerke:

Have you ever heard the saying, ‘Simplicity is the ultimate sophistication’, they’re famous words from an even more famous person… Leonardo Da Vinci. We try to remember this quote whenever we begin to organise an event, we always endeavour to keep things simple and truly relevant to the actual happenings of the day. For the S58 Tech Night, to keeps things simple we knew we wanted to display all 6 variants of BMW S58 powered cars and equally as important, we wanted them all to be at different levels of modification. Luckily for us, we had a plethora of G8X and F97 customer cars to choose from!

Come event day, it was business as usual till about 4:30pm where one side of the workshop was emptied out and prepared for the evening’s activities. By 6pm we had the marquee set up outside, with some seating, tables ready for food and the first few display vehicles began to arrive.

First was Adriaan in his BMW G82 M4 Jahre Edition, then Brad in his BMW G83 M4 Cabriolet and only moments later Josh in his BMW F97 X3M Competition. Each car slotted into their spot for the evening, with their owners beginning to mingle. By 6:30pm the other four display cars had arrived, Troy in his BMW G81 M3 Touring, Ashleigh in her BMW G80 M3 Sedan, Ben in his BMW F97 X3M Competition and finally Michael in his BMW G87 M2. With all the cars set into position, the next thing to set up were the pizzas!

Absolutely exceptional experience at Eurowerks Castle Hill. Oscar and his brother Ozzy run the workshop with real passion and professionalism. From the first conversation, you can tell they genuinely care — not just about the cars, but about their customers as well.

They took the time to explain everything clearly, kept me updated, and made sure the job was done perfectly. The attention to detail and pride they take in their work really stands out. It’s rare to find a workshop where you feel completely confident leaving your car, but with these two, you know it’s in the best hands.

Their honesty, care, and dedication are on another level.

Highly recommend — true professionals.

Couldn’t recommend Eurowerks Castle Hill enough. The owner, Oscar, is honestly the best in the business. He’s knowledgeable, genuine, and takes the time to properly explain everything without making you feel rushed or pressured.

You can tell he genuinely cares about both the cars and the customers. The attention to detail and quality of work is outstanding, and the whole experience felt professional from start to finish.

It’s rare to find someone who combines skill, honesty, and great customer service the way Oscar does. If you have a European car and want it looked after properly, this is the place to go.

Harley Soriano

Absolutely fantastic service! My Audi A3 was handled with great care and expertise. The team diagnosed the issue quickly, explained everything clearly, and had my car running perfectly in no time. Friendly, professional, and reliable — I wouldn’t trust my car with anyone else. Highly recommend

Taylan Koroglu

Hands down one of the best workshops I’ve dealt with. The team at Eurowerks Castle Hill are genuine professionals who clearly specialise in European cars. They diagnosed the issue quickly, explained everything in simple terms, and kept me updated throughout the whole process.

No hidden costs, no surprises — just honest advice and high-quality workmanship. The car came back running perfectly and you can tell they pay attention to detail.

It’s hard to find mechanics you can truly trust, but these guys have earned it. Highly recommend to anyone with a Euro car looking for reliable and skilled technicians.

Christopher Zaiter

I had an awesome experience with eurowerke Their customer service was amazing — super friendly, helpful, and professional.

They handled my car with so much care and attention, and when I got it back it honestly felt better than ever. Everything runs smoother now and I couldn’t be happier.

Highly recommend

Michel Fu-Strelnikov

Absolutely amazing service from start to finish for all my cars. Honest, reliable, and took the time to clearly explain what was wrong and what needed to be fixed. Highly recommend to anyone looking for quality workmanship and great customer service.

Colin Barnes

I’ve been using Eurowerke for years now & can’t fault their workmanship, care & attention to detail. I appreciate the clear communication on any work that needs doing & feel that having them work on my cars gives me plenty of peace of mind & extra value to the car itself.

2020 VW Golf Alltrack. Recommended by a Work Colleague . My initial enquirey was for 120K Service, DSG and Differential Service. I promptly received a quote and was happy with the cost. I was able to book my car in earlier which was great. Communication, excellent. Service, excellent. Further to the Service I was informed of other work required and supported with photos one of which I had done. I even got their Sticker on the back as I will be a repeat customer.
Previously serviced by VW Liverpool but let down by poor communication.

Dr Jee SL

I am very satisfied with the work done at Eurowerke when I sent in my VW Golf for repairs. Not only did I get in quickly with an appointment, Phil even price matched the charges. On top of that the car was thoroughly washed and cleaned before collection. My go to place to have any Continental cars serviced or repaired as I also service my Audi A6 there.

Great customer service. They made the whole process from booking to collection so smooth and easy. Great communication in between to give you an understanding on any recommendations. I would have no hesitation in telling all my friends about the amazing team at EuroWerke

I never write reviews but Eurowerke is worth writing a review for!
First of all, the mechanics are amazing and pick up on things you may not pick up on. They are always working with you to find the cheapest option for you.
The prices of the services are amazing and so much cheaper than going to the car dealership.
They are always in contact with what is happening with your car as well as contacting you if your car needs additional repairs before starting them.
Lastly, the receptionist is AMAZING! She is adaptive to your needs (the way you want to be contacted), easy to understand, has amazing knowledge on cars as well. She works with you if you need any help with anything regarding your car! And most of all, she’s friendly and approachable
Thank you so much! We will continue to bring our cars here!!

Renata Jelisavac

The team are professional, easy to deal with and super quick at getting back to you. My preferred method of contact was text and Annabelle was able to support me with this. I love that they send out a report to you with any issues they find and you decide whether to go ahead with getting it fixed or not. The team of mechanics had picked up issues with my car that other service centres haven’t and they aren’t phantom issues as it’s things I’ve brought up myself but never got an answer on. I’m really happy with the service, and the way I was treated and will definitely recommend EuroWerke to friends with European cars. Thank you team EuroWerke.

I could honestly spend an entire day writing about my experience with Eurowerke and still not capture how incredible this team is. Over the past year, they’ve completely changed what I thought owning a European car would feel like. For me, it was never about just finding a workshop — I wanted a place I could trust, people who felt like family, and that’s exactly what I found here.

From the very first visit, Eurowerke made me feel like so much more than just a customer. Every interaction is genuine, every detail is cared for, and every job — big or small — is done with the kind of passion and pride you just don’t see everywhere. Their attention to detail is unreal, and the quality of their work speaks for itself.

I would never let anyone else touch my car. The trust I have in this team is unmatched, and the love they put into their craft is something you can see and feel the moment you walk in.

A massive thank you to everyone at Eurowerke for not only bringing my vision to life but for making the whole journey special. You’ve set the bar so high, and I couldn’t be more grateful. Nothing but love and respect for the entire team — you’re truly one of a kind.

A special thanks to Annabelle she is always amazing to work with! She gave me great recommendations and ideas, and even handled all my last-minute suggestions without any fuss. Super helpful, friendly, and made everything so easy.

If you love your car, Eurowerke is the only place you’ll ever want to go.

These guys are great, took sometime to get my car in for rear brake replacement on my BM but, its because they are busy and obviously known for doing great honest work at a great rate, so worth the wait in my view. Thanks again.

Mustafa Qaisar

Very happy with Phil and the team. New customer at Eurowerke and they’ve taken great care of my X5. Will continue to send my European cars their way. 💯

Robert Bugariu

Phil and the boys at Eurowerke are a class act. Can honestly say it has been one of the best customer service experiences I have had period. I drive a M135i and the guys have taken amazing care of her. There was a small leak from something they had to fix a short while ago and they completely re did the job for me completely free and without any kind of awkward conversation about payment etc. They also helped me fix a small coolant leak that they had nothing to do with for free, they spent about 45 min on the car. The garage is immaculate also. Always clean and staff are always professional.

I would not hesitate to send anyone to them. Very highly recommended! Can't see myself ever going to a different garage, whether maintenance or performance etc.

If they quote you higher than some other place it's worth it.

Damian Huntingdon

Had my VW Touareg in to have the injector seals replaced after being quoted elsewhere for triple the price it cost to have the work done with EuroWerke. They were so honest and the quoting system is so simple, thank you do much I am now a customer for life!
