Haldex Service – How We Refurbish Your Unit
1. Checking Your Controller's Condition and Repair Options
First up, we do a thorough visual inspection of your controller and then put it through its paces on our test bench. This helps us figure out if we can repair it to ensure it runs reliably for years. If it's severely damaged, no worries – we'll get in touch to offer you alternatives, like swapping it out for a new or refurbished unit. Our main goal is always to give you a lasting and effective fix.
Assessing Your Controller's Health
Here, we really dig deep into diagnosing any damage to your controller to make sure it's actually repairable. We run it on the test bench and take all the crucial measurements.
Controller Beyond Repair? Here's What's Next
If your controller is severely damaged, we've got alternative solutions for you. We can offer a replacement with either a new or a refurbished unit, always making sure it fits your specific needs.
2. Main Board, Components & Casing Repair
Here, we get down to business, repairing the PCB, giving it a thorough clean, and checking it over. We also meticulously fix up the casing, cover, and any other controller components, making sure every little detail is perfect. Everything gets carefully prepped for reassembly.
PCB Repair & Cleaning
We meticulously clean the PCB of any grime and inspect it for damage. If needed, we carry out repairs and get the board ready for its next life.
Controller Casing Refurbishment
We also repair or replace the control unit's housing and cover, fixing any damage to restore its full functionality and appearance.
Once the controller board is repaired, we apply a professional protective coating to shield it from water damage and corrosion. We do the same for the controller's cover. Then, we meticulously reassemble and seal the unit, ensuring your 4x4 drive will run reliably. To wrap things up, we perform a final test to guarantee everything's working perfectly.
Protective Coating & Final Testing
Once the controller board is repaired, we apply a special protective coating to guard against mechanical damage, moisture, and corrosion. To top it off, we run a final test to confirm your controller is working perfectly.
And there you have it! Your Haldex controller is now good as new.
Thanks for taking this virtual repair journey with us. We always go the extra mile to make sure Haldex controller repairs are fast, effective, and super precise.

I highly recommend him. I’ve been to several repair shops where they suggested replacing the entire rear axle, rebuilding it, or performing other repairs. This guy, however, solved the problem in just a few minutes using a computer, and the cost of the service was a fraction of what the others quoted. You can tell he knows what he’s doing. Thank you for your help.

Professionalism all the way... And super fast repair... My 5th gen Haldex control unit is back from the dead and running like a dream! Plus, the unit got professional moisture protection...

I'm super happy I found this company. My Haldex controller bit the dust, and a new one was just ridiculously expensive. Thanks to these guys, I got my car fixed for a reasonable price. I totally recommend them to everyone!

Both the phone contact and the service itself were super professional. The cost was way lower than buying a new, or even used, Haldex IV control unit. I can totally recommend this company to anyone dealing with a non-working 4x4 drive.

I'd heard a lot about this place before, and it was all good stuff. Every single person who recommended them was right – 5 stars just isn't enough! The help was quick and to the point, with advice over the phone even before I sent in my controller. They were available by phone long after closing hours too. The repair was fast, spot-on, and super affordable. I was worried no one would be able to help with my Haldex, but luckily I found this workshop. They helped me understand exactly what happened with my controller and what the implications were. Huge thanks! I honestly recommend them.

This is my first time leaving a review, but I just have to spread the word about these awesome pros! I had an issue with my Haldex; it just wasn't working. I visited a bunch of specialists in my area and made tons of calls, and everyone kept saying the differential needed reconditioning, and probably the pump too. Finally, I stumbled upon this service, and after a phone call, I heard something completely different – it was hard to believe! This guy was the only one with a different take, but I decided to give it a shot. I booked an appointment, went there, and the technician fired up his laptop, did some adaptation and calibration, and boom, everything worked! All for a symbolic amount, not thousands. Seriously, I recommend this to anyone with a problem; give them a try, because this guy really knows his stuff!

Hey there. I called this guy today about my non-functioning Haldex rear-wheel drive in my Passat B8, and he was super helpful and solved my problem. This pro really knows his stuff, he knows what he's talking about, and on top of that, he's friendly and polite. Wish there were more specialists like him! I wholeheartedly recommend him.

So, two days before a roughly 1500 km trip north, my Haldex unit decided to kick the bucket – just my luck! The part was only available at the dealership in about a month, costing 4000 PLN. I scoured the internet, but couldn't find anything available immediately, and even used parts were ridiculously expensive. Then I stumbled upon this service online. After a quick chat and diagnosing the issue, I dropped off the part since I was nearby. The repair was LIGHTNING FAST! The part was ready the very next morning. This guy's a PRO! He even helped me out again later that same day. Rating: 100/10. And the price? Totally fair for such solid and speedy work.

I rarely leave reviews, but for this workshop, my conscience practically forces me to give 5 stars – and honestly, that's still not enough. Seriously, I didn't think such experts still existed!
I'm from Warsaw, and my Passat Alltrack B8 had an issue. One of the 'Warsaw specialists' quoted me 2300 PLN for a supposed Haldex adjustment, which – as it turned out later – is total BS. You either swap out the friction elements for new ones, or you just clean them and top up with fresh oil (which wasn't even included in his price!). When I asked if the 4x4 drive would actually work after this service, he replied: 'I guarantee my work, but whether the drive will work – I don't know, because there's also the pump and the control unit.' Thankfully, I didn't go for that service.
At another workshop, they replaced the pump with a new one, but the 4x4 drive still wasn't working. That's when I was told the control unit also needed replacing...
Luckily, I stumbled upon haldexserwis.eu. I explained the problem, and a super friendly, competent guy diagnosed everything over the phone. He honestly said that, in his opinion, both the drive and the control unit were fine, and the problem was just with the adaptation.
And guess what? Every single word he said was spot on!
The 4x4 drive came back to life, the operation was a success, the old pump stayed, calibration was done, and everything works perfectly.
Huge respect to the owner for his expertise, honesty, and vast knowledge. I wish I only met people like him in life!
Cheers again and a massive thank you!

I called you about an issue with my 4th gen Haldex. After a brief chat, we arranged a longer call for when I'd be with my car and VCDS. Based on the parameters I provided, you diagnosed a valve fault. You gave me precise instructions on what to do, and I followed them. After an ultrasonic cleaner flush, the valve came back to life, the drive works, and the car is flying! 😁
I wholeheartedly recommend this guy; he's a true specialist, knows his stuff, and has clearly worked on countless Haldex units.

Seriously, I can't recommend them enough! The service is absolutely top-notch. My Haldex issue was sorted out super fast, and the communication was excellent. It's clear the guy really knows his stuff when it comes to Haldex operation and service. Plus, he gave me some really valuable tips on how to properly maintain the system to avoid future problems. Again, highly, highly recommend!!!

This guy is a gem! He did what others said was impossible. He really knows his stuff. If you're looking for a real pro for Haldex controller repair, he's your guy. He'll explain everything, tell you the best approach, and get it done. He guarantees his work. There are two ways to get it fixed: either bring your car to him, or you can send him the controller, and he'll repair it and send it back 100% done!!! He seriously knows his stuff. Thanks to him, my car is running perfectly. So, if anyone has a problem with their Haldex drive controller, it's no problem for this expert. And one more thing: don't listen to others who say it can't be done, because I know it CAN be done!!!! My controller was burnt and flooded, but he fixed it, and my Tiguan is flying now, which is the most important thing. And as for the cost, it's super cheap for such a job 💪👍. Once again, a huge thank you. I'll be recommending your Haldex service to everyone.

They have extensive knowledge of Haldex and its common faults. After just a few words on the phone, you know you're dealing with an expert in the field. The controller was repaired super fast, the Haldex came back to life, and hopefully, it stays that way. I wholeheartedly RECOMMEND them!
