The significant drop in the price of the used Tesla Model S has attracted the attention of many EV enthusiasts. However, some models with the Large Drive Unit (LDU) hide higher costs for owners who expected a 12-year-old vehicle to require no maintenance for a modest purchase price. The Tesla LDU, found in all Tesla Model S and X vehicles with PxxD or RWD configurations (P85, P90, S85, S90, S75, S70, S60), is one of the most demanding and expensive components to repair.
Nearly two years ago, we already discussed the flaws and reasons for the low reliability of these motors. Read the full article below:
We followed up with a guide on which Tesla models are the most reliable and recommended for new EV enthusiasts. However, if an LDU failure occurs, the current repair cost at EV Clinic is €2,400 for motor rewinding and €2,800 for a complete motor remanufacturing, bringing the total cost to €5,200 + VAT. In comparison, the price at a Tesla service center is currently around €6,500 + VAT.
Unfortunately, our pricing at EV Clinic reflects our commitment to delivering the best possible quality and maintaining the highest level of trust. This includes a 2-year warranty with no mileage limit. The results of our work speak for themselves, with real-world testing proving the durability of our repairs.
One notable example is Hansjörg von Gemmingen-Hornberg’s Tesla P90, which had accumulated 1,800,000 km. After we repaired his motor using all of our advanced technological expertise, the motor has now covered 450,000 km without a single issue, breaking the streak of 13 previously replaced motors. This achievement underscores the unparalleled reliability of our repairs and he is the man who gave us reason to assemble and name eDrive kit a “Holy Grail”. LINK HERE
After three years and several hundred repaired LDUs, we can confidently say that we have the most durable long-term solution for these electric motors. It’s important to highlight from our findings that RMN stators in LDU motors are of very poor quality, often causing significant damage to the entire motor. Eventually, they lead to insulation failure, resulting in the vehicle coming to a halt and bearing arcing due high rotor discharge.
To address this issue permanently, we have developed an improved solution by rewinding the stator with enhanced industrial-grade materials, ensuring reliability and longevity. LINK HERE . And to openly offer our kit and know-how we assembled “holy grail” kit for all independent workshops LINK HERE
