Fully refurbished using our 5 point plan outlined below. All parts come fully invoiced. Please check the item number matches your item number exactly.If you are unsure - message me with your registration or VIN number and I will check for you. Please be aware that not every item is plug and play every time - some items need to be coded to your car so have a competent auto electrician to hand who has the relevant software. We carry out a 5 point refurbishment process for all of our parts. Every item is fully tested and disassembled. All components and contacts are cleaned. All soldering is carefully reflowed to close any developing cracks, dramatically extending the life of the unit. Every unit is rebuilt by hand and retested. We will use whatever method will get your item to you the fastest, and with the best outcome. We actively avoid Hermes, for all those worried by negative experiences in the past.
