DT guarantee
DIESEL TECHNIC offers its customers a 24 month guarantee for DT brand quality spare parts.
This unique guarantee is our way of thanking our customers all over the world for over 35 years of continuing confidence in the quality of “DT” brand spare parts for commercial vehicles. At the same time it is a confident statement of trust in our own “Quality made by DIESEL TECHNIC”, and a future incentive to fully confirm the confidence shown in us. 
With the introduction of this guarantee, DIESEL TECHNIC is emphasizing the demand that the “DT” mark of quality be the first-choice alternative to original spare parts from the leading European commercial vehicle manufacturers.
The guarantee period of 24 months, which is unprecedented in the automotive aftermarket for commercial vehicle spare parts, exceeds the vehicle manufacturers’ limited guarantee time periods for original spare parts.
| Brand | Guarantee period |
| Scania OE | 12 months |
| Volvo OE | 12 months |
| Mercedes-Benz OE | 12 months |
| DAF OE | 12 months |
| MAN OE | 12 months |
| DT spare parts | 24 months* |
The basis for the introduction of the new “DT” spare parts guarantee is high quality products which results in a minimal complaint rate. For this, outstanding quality management is vital, from development across the entire manufacturing and marketing processes.
