Is the SRS Light TÜV-Relevant?
Is the SRS warning light relevant for TÜV inspection?
Yes, the SRS control light (airbag warning light) is fully relevant for TÜV inspection during the main inspection (HU). A continuously illuminated SRS light is classified as a major defect and results in denial of the TÜV sticker. The vehicle only passes the HU once the fault is corrected.
The TÜV inspector checks when the engine starts whether the airbag warning light briefly illuminates (self-test) and then goes out. If it remains on continuously or does not illuminate at all, this is considered a defect – in both cases, the restraint system is not functioning correctly.
Why is the SRS warning light so important for TÜV inspection?
The SRS light is the only visible indicator of the entire airbag system's functional status. If it remains on continuously, airbags and seat belt tensioners may be disabled – in an accident, occupants would have no supplementary protection. The legislator classifies this as a significant safety risk.
Since 2006, TÜV has systematically inspected electronic safety systems. In addition to visual inspection of the control light, modern inspection organizations also read the fault memory via the OBD interface on newer vehicles – bypassing or disconnecting the light is detected this way.
What exactly does TÜV inspect?
The inspector checks three things: First, the lamp test (light must briefly illuminate when ignition starts), second, the light going out after 2-5 seconds, and third, on newer vehicles, the electronic fault memory via the OBD-2 interface. All three points must pass.
| Inspection point | What is inspected | Result if defect |
|---|---|---|
| Lamp test | Does the SRS lamp briefly illuminate at startup? | No illumination = defect (lamp faulty/tampered) |
| Extinguishing | Does the light go out after self-test? | Continuously on = major defect |
| OBD readout | Are fault codes stored in the SRS control unit? | Active errors = defect (on newer vehicles) |
Difference by first registration
For vehicles first registered on or after January 1, 2018, electronic inspection via OBD is mandatory. For older vehicles, inspection is limited to visual inspection of the control light. In both cases, a continuously illuminated SRS light results in failure.
What defect classes exist?
A continuously illuminated SRS light is classified as a "major defect" (EM). This is the second-highest defect class – only "dangerous defect" is worse. With a major defect, the sticker is denied and a re-inspection within one month is required.
| Defect class | Designation | Consequence |
|---|---|---|
| OM | No defect | Sticker is issued |
| GM | Minor defect | Sticker is issued, defect to be corrected |
| EM | Major defect (SRS light) | No sticker, re-inspection required |
| VM | Dangerous defect | No sticker, vehicle immobilized |
What to do if the SRS light is on before TÜV inspection?
Have the fault corrected at a workshop before your TÜV appointment. First diagnose the cause (read fault memory), then repair and finally clear the fault memory. Only then go for the HU – this saves the cost of a re-inspection and an additional workshop visit.
- Visit workshop:Have the airbag control unit fault memory read
- Clarify cause:Is it a sensor, the mat, the control unit, or a connector?
- Perform repair:Replace defective component or clear crash data
- Function test:Light must go out after engine start
- Go for HU:Pass easily with correct system
Crash data as most common cause
Especially with used cars, crash data from a previous accident is often still stored in the control unit. Clearing this data restores full function – without expensive control unit replacement. Airbag24 offers this repair for all brands: TÜV-safe, with over 20 years of experience and up to 50% cheaper than a new part.
Can you manipulate the SRS light for TÜV inspection?
Any manipulation of the SRS system is illegal and will be detected during the HU. The inspector checks the lamp test (light must briefly illuminate) and reads the fault memory electronically on newer vehicles. Disconnecting or bypassing the light is immediately detected and can have criminal consequences.
- Disconnect lamp:Detected because it does not illuminate when ignition is turned on
- Clear fault memory without repair:Error returns immediately during self-test
- Install simulator:Covers the error but is legally problematic
- LED manipulation:OBD readout shows the error anyway
Instead of manipulating: Fix the actual cause. In most cases, the repair is cheaper than expected – especially if only crash data needs to be cleared or a connector needs cleaning.
Frequently asked questions about the SRS light during TÜV inspection
Here you will find answers to the most important questions about the SRS control light and the main inspection.
Do you fail TÜV with every illuminated warning light?
Not every warning light is a major defect. The SRS/airbag light, ABS light, and ESP light typically result in failure. The engine control light or tire pressure warning can sometimes be rated as only a minor defect depending on the situation.
How long do I have for the re-inspection?
The deadline is one month from the date of the HU. During this time, you must correct the defect and present the vehicle again. The re-inspection costs between 15 and 30 euros. If you miss the deadline, the entire HU must be repeated.
Does TÜV also check if the light does NOT illuminate?
Yes. The inspector also checks the so-called lamp test: The SRS light must briefly illuminate when the ignition is turned on. If it does not, the lamp could have been intentionally disabled – this is also rated as a defect.
What does it cost to repair the SRS light for TÜV inspection?
The cost depends on the cause. You can find exact prices for your vehicle model in our shop. At Airbag24, you get professional control unit repairs and matching spare parts for all brands – TÜV-safe and with warranty.
