Made-in-China battery packs are bad!

By Strom Trooper

Media hype around “Made in China” battery systems being the “best” has never been confirmed in real-world practice. We are raising serious concerns about Tesla Model 3/Y LG NCM811 battery packs (LGES Nanjing), which show extremely high failure rates and a noticeably shorter end-of-life compared with Panasonic NCA packs (Made in USA). In over 90%…

Tesla LDU “coolant delete” fatal failures

By Strom Trooper

2 units in one week (Austria & Slovenia) – Both units failed shortly after being “repaired” using a coolant-delete workaround. This is exactly the reason why we never adopted that method in the last 4 years. Instead, we developed a complete, engineering-grade repair process and the LDU Holy Grail e-Drive KIT, which has proven itself…

EQC ZF eDrive repetative failure – SiC seal wrong technology

By Strom Trooper

Front Drive Unit Failure – Mercedes EQC We are once again seeing the same repeating failure pattern on ZF asynchronous induction motors: coolant intrusion through the SiC mechanical seal. Although induction motors are, by design, more durable and more sustainable than PMSM units (in terms of serviceability and long-term stability), several OEMs (Audi, VW, Mercedes)…

If you drive a hybrid – may God help you – NOT REPAIRABLE

The Yellow Dotted Line on Tesla’s Dashboard – What It Really Means

By Strom Trooper

One of the most common questions we receive after battery repairs is about the yellow dotted line on the energy display. Many owners worry that this indicates a defect or a problem with the repair. In reality, this feature is a normal part of Tesla’s battery management system (BMS), designed to protect and optimize the…

Tesla SDU Diff Gear Rebuilding – Halfshaft rattling solved

By Strom Trooper

Dear Tesla community : Making the Small Drive Unit immortal wasn’t easy – but it also wasn’t impossible. Simply buying existing repair kits is not enough because milling or clicking noise was still there. The clicking noise and axle vibrations we noticed on an SDU we received over two years ago seemed like an isolated…
