TÜV supplementary part certification

Increased performance using chip tuning devices

All technical modifications to a vehicle must always be entered onto the vehicle registration documents. This is particularly the case for measures that increase performance.
The legal basis for this is set forth in the German road traffic licensing regulations (StVZO).

In order to obtain TÜV supplementary part certification the following inspections must be carried out:

• An exhaust gas emissions measurement in accordance with EU Directive 70/220 or 715/2007/EEC
• Vehicle noise emission measurement in accordance with EU Directive 70/157/EEC
• Engine power measurement in accordance with EU Directive 80/1269/EEC
• Top speed measurement in accordance with ECE Regulation no. 68
