Germany has a rich automotive culture, and tuning cars is a big passion for many drivers. From turbocharged engines to paint jobs, personalisation is a form of expression and is becoming more and more popular.
However, before you start modifying your vehicle, it's important to understand the legal implications and how it affects your insurance (failing to do so could leave you uninsured when you need coverage most).
Before making any changes to your car, you should become familiar with car insurance (Kfz-Versicherung) in Germany:
| Coverage Type | German Name | What It Covers |
|---|---|---|
| Third-party liability | Haftpflicht | Covers damage you cause to others. This is legally required |
| Partial coverage | Teilkasko | Protects against theft, vandalism, fire, natural disasters, and broken glass |
| Comprehensive | Vollkasko | Includes everything above plus damage to your own car, even if you're at faultYou can find further information about car insurance in our article |

| Category | Examples |
|---|---|
| Performance tuning | Turbochargers, engine remaps, sports exhausts |
| Visual upgrades | Custom paint, decals, spoilers, body kits |
| Structural changes | Suspension kits, non-standard rims, lowering |
| Interior modifications | Racing seats, custom infotainment systems |
| Lighting | Underglow, LED strips, non-standard headlights |
Insurers don't just see modifications as upgrades, they see potential risks. Changes can affect your coverage, premiums, and eligibility.
Any modification raises the following questions for insurers:
These answers determine whether they'll insure you, and how much it will cost.
| Modification Type | Typical Impact |
|---|---|
| Performance upgrades | Significant premium increases |
| Body kits and visual changes | Moderate increases, theft concerns |
| Interior upgrades | Minor to moderate increases |
| Unapproved lighting | Could void your policy if you don't tell your insurer |
Some insurers may even refuse coverage if your car is heavily modified.
If you modify your car and don't inform your insurer:
Always declare modifications to your insurer, even if you think they're minor.
In Germany, most modifications need approval from the TÜV (Technischer Überwachungsverein) before they're street-legal.
Some parts come with an ABE certificate, which is like a blanket approval. If a part has ABE, just keep the certificate in your car, it's usually all you need.
If a modification doesn't have ABE, you'll need a TÜV inspection and approval. Without it:
Modifications change your vehicle's risk profile, which directly affects your car insurance premiums.
| Factor | How It Influences Premium |
|---|---|
| Increased power | More speed = higher accident risk → higher premiums |
| Visual customisation | Flashy looks attract attention → higher theft risk → higher premiums |
| Non-standard parts | Harder/more expensive to repair → higher premiums |
| Safety modifications | Things like better brakes or airbags → may lower your premiums |
Some insurers specialise in modified vehicles. Here's what they can offer:
If you've got a vintage ride or a heavily customised vehicle, classic car policies might be a better fit. They often offer:
Even small changes count. Always let your insurer know about any modification, undeclared changes are the fastest way to get caught out when you need coverage most.
Keep a clear record of all the necessary documents. Having these on hand makes life easier if you ever need to make a claim:
Not all insurers are the same. Some are much more modification-friendly than others. Take the time to get a few quotes, you might be surprised at the differences.
Insurance brokers familiar with modified vehicles can help you find appropriate coverage and understand requirements better.
Before modifying your car, check whether it needs TÜV approval. Non-compliant modifications not only put your insurance at risk, they can also make your car illegal to drive.
| Do | Don't |
|---|---|
| Declare all modifications to your insurer | Hide changes to keep premiums low |
| Get TÜV approval where required | Assume small changes don't matter |
| Keep documentation in your vehicle | Ignore ABE requirements |
| Compare specialist insurers | Settle for the first quote |
