As all of our spare parts are custom-made and high-precision devices, some of them can only be manufactured by us on a prepayment basis. Therefore you cannot return them or cancel your order during production and receive your prepayment back. In case of faulty assembly or manufacturing defects, the part will be replaced. We cannot tell you exactly our production time, as part of the work is carried out by third parties. You cannot return the part if you cannot install it or if you realise you have made a wrong choice. Only in case of a defect on our part (prior to installation of the part), we will make a replacement or refund your money. During operation, we do not accept any complaints, as we cannot verify that our parts have been installed correctly. We do not provide a guarantee for the engine. Installation and operation is your responsibility and that of your mechanics. All of our parts that we sell have been tested for over 3000km on our vehicles. We will be happy to advise you on installation. Do not hesitate to ask us, we will always help. We have the right to refuse you to buy our parts without giving any reason. 

We offer a guarantee: This means that you can report a fault within one year, provided the part has not been installed. We will replace it or refund your money. If the part is resold, we are not responsible for the warranty.
