Have your towbar programmed by Carware

Do you want to install a tow bar, or have you already done so, but the electronics aren’t working properly and you want to have it programmed? At Carware, we can do it for you! Many vehicles have advanced onboard computers that must first recognize additional components, such as a tow bar, before they function properly. Without proper registration, parking sensors may continue to beep or the trailer lights may not work properly. This can lead to malfunctions, error codes, or even safety issues. So have your tow bar programmed quickly by Carware! That way, you can hit the road without any problems.

What do we do?

When we program your towbar, your car’s software is adjusted or updated to correctly recognize the installed towbar. The car needs to know that a towbar is connected so that electronic systems can anticipate this. This includes automatically disabling parking sensors when towing a trailer or caravan. For BMW cars, programming the towbar is often mandatory to properly utilize factory options and safety features.

How does programming a tow bar work?

We program towbars using dealer-grade diagnostic equipment. Our certified technicians connect your car to the readout computer, check the software, and perform any necessary coding or updates. This process configures the on-board computer to recognize the towbar and use it correctly with all existing systems.

The importance of learning a tow bar

If you don’t program your tow bar, your vehicle could display error messages or disable important functions. The parking sensors keep beeping, you’re missing trailer stabilization, or the reversing camera isn’t working properly. You could even fail your vehicle inspection (APK) if the lights or electronics aren’t functioning properly. By having your tow bar programed, you ensure that your vehicle recognizes all systems and controls them correctly, allowing you to drive safely and without frustration.

Cases

When is it necessary to have a tow bar programmed?

You must have a tow bar programmed after installing it on a vehicle with a modern on-board computer or CAN bus system. This applies to both original and aftermarket tow bars. Even if you’ve had a tow bar for a while, but are experiencing electronic malfunctions or malfunctions, having the tow bar programmed is often the solution.

The software specialist for BMW, Mini and Rolls-Royce

We can program towbars for major car brands like BMW, Mini, and Rolls-Royce. Our specialists know exactly which software adjustments are needed to ensure your car recognizes the towbar and anticipates its use. Because each brand has its own protocols and requirements, expertise is essential. We ensure that the towbar is programmed according to factory specifications and is fully compatible with your vehicle’s original functions.

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!

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.

Joost, dank voor je leuke review. En veel rijplezier toegewenst in je Z3!

Highly recommended 👌👌

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!

Response from the owner 09:59 28 Jul 25

Ha Piet,Het werken aan een E92 M3 is altijd extra leuk. Fijn dat je tevreden bent, en het mooie V8-geluid was inderdaad al van ver te herkennen ;-)Hartelijke groet,Carware

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
