Every year, we program dozens of towbars for BMWs, Minis, and Rolls-Royces. A towbar is a very welcome upgrade.
After installing and wiring the tow bar, the car needs new software. The tow bar module needs to be learned and programmed. The tow bar also needs to be registered with various control units in the vehicle. This ensures that the traction control, parking sensors, and iDrive system, among others, are also aware of the tow bar. The reversing camera, for example, has a special tow bar mode. Traction control and ABS may also react differently after coding the tow bar.
We can perform these software modifications expertly and provide all the parameters the control unit requires.
This can even be done remotely. So no travel time, and no additional costs.

Very satisfied with Carware! My dashboard lights stopped working, and owner Jan quickly found the cause. He honestly suggested I could fix it myself to save money—and he was absolutely right. Friendly service (even offered a drink) and very knowledgeable. Absolutely recommended! You won't find service like this again! 5/5 ⭐️

After replacing several parts on my BMW M140 with no success, the ECU turned out to be the culprit. After some online research, I found Hagenaar Carware, where I received excellent service. Jan quickly diagnosed the problem correctly. He clearly explained the problem and the costs. Clear communication, no surprises, and expert service. Highly recommended for anyone with electronic problems with their BMW or MINI.

My car has been parked since July 7th due to a malfunction in the electronic steering lock on my BMW E90.
Last year, the entire steering column was replaced, but after a few months, the same problem arose. No one could solve it, but after a long search online, I found Jan, and after a clear explanation and a potential solution, I regained hope.
Jan remotely—how?—really got my car running again and immediately wrote down all the malfunctions and error messages.
Jan is a hero! It's a shame you can only give 5 stars and not 10, otherwise he would have definitely earned them!

I had a problem with the ROC module for my BMW. Jan neatly fixed all the error codes and reinstalled the module. A fantastic solution, instead of having a new and expensive module replaced at the garage. Jan communicates quickly and honestly about the options and any risks. He also provides immediate clarity about the costs. In short, I understand why all the reviews here are 5 stars, and this one adds another 5 stars!

The ECM of a 320 convertible was repaired and updated with new software. The car now drives smoothly and better than ever. Excellent service! Perfect! Highly recommended!

I have an old BMW Z3, and after winter storage, it wouldn't start.
Jan was able to come on-site within two days to scan the Z3, but unfortunately, that wasn't possible because the Z3 has an older system.
Luckily, Jan still had an old laptop with the correct software.
He quickly realized the AWS module was malfunctioning. He gave me tips on how to work around this and adjusted the ECU. And yes, it's running like a charm again.
Excellent, clear communication, good advice.
Simply a true professional.
We need more of them.

We had Jan install original BMW cruise control in our BMW Z4. Everything was expertly installed and thoroughly tested. Jan works calmly and consistently. Highly recommended!

Ha Johan,Fijn dat je blij bent met de originele cruise control. Origineel blijft in onze ogen de mooiste oplossing voor je Z4.Hartelijke groet,Carware

After some online research, I found Hagenaar Carware for an upgrade to the DCT gearbox in my BMW E92 M3, specifically the GTS software. After contacting them through the app, I was able to quickly schedule an appointment.
Once I arrived, Jan already heard me 🥳. He immediately grabbed the laptop to check everything for error codes, after which the software could be installed. Meanwhile, Jan changed my menu to Dutch (it was in English), completely free of charge 👌
After an hour, we were back on the road, and the shifting was so incredibly fast.
Thanks, Jan!

Jan is very knowledgeable and specialised in BMW. He had the right equipment and didn’t leave a mark on the car!
Was looking for a while for CarPlay for my X1 and he was very professional since the first contact. And he delivered exactly what was promised. Working like a charm. Thank you! Highly recommended.

Amazing service! He really knows his stuff and is very kind. I came because my car was not coming through the “vehicle safety inspection” because of a E-CALL error. Since 2023 its mandatory to work in The Netherlands.. Additionally he gave me advice about error codes, their meaning, auto mirror fold and digital speedo also coded in. Pricing is also very fair.
Recommended!

Recommended by a friend, and contacted Hagenaar Carware. Wanted to change the language of the infotainment and install bluetooth and aux in on my BMW E60. This was all perfectly done by Jan. Good service and I will recommend this to anybody else.

Went out to get cruise control fitted to the car, as well as changing the language of the infotainment system to Dutch. Everything works as told beforehand. He was also so kind to add in a digital speedometer and changing the wipers so that they go down even after shutting off the engine. Beforehand he did an inspection for any faults in the car, which surprisingly came up clean. Very kind and happy to tell you about the process as he goes along.

Top service! He did the apple CarPlay full screen coding for me very happy with that works perfect. And recently over the air service reset because I do my maintenance myself this is a very good service for me as a home mechanic. Every time very fast response and takes time to explaining the things he do to your car. I would recommend his expertise to anyone
