Warranty claims

The trust in the branded products is rewarded with a 24-month (DT Spare Parts) or 12-month (SIEGEL Automotive) brand guarantee. The guarantee is applicable to the whole supply chain and begins on the day on which the last purchaser (= workshop customer) verifiably acquires the product. To prevent unnecessary warranty claims in advance Diesel Technic provides practice-oriented assembly instructions. In product trainings and videos for workshop customers, valuable and practical tips are conveyed by experienced commercial-vehicle master mechanics. Please do not hesitate to contact us. Should a problem arise with our branded products within the warranty period, we will assist you with help and advice.

Feedback

We regularly carry out customer questionnaires, for example the Partner Survey and the half-yearly Partner Dialogue, in order to enquire for your valuable feedback and to measure your satisfaction. Your feedback contributes to guarantee the product and service quality; for that reason, all deduced measures support the continual improvement process to your benefit.

Thank you!
