BMW X5 F15 40e – Another dead Hybrid with 150,000 km

The battery system is worn out, with 1-2 cells completely damaged. The only reliable solution in such cases is to replace all modules, ensuring the next 100,000 km before a new cell replacement is required. However, this is only possible if the BMW dealer does not permanently deactivate the battery system using the EOS tool.

Patching with used modules has proven ineffective, as replacing only one module leads to the rapid failure of the next weakest module. Such an approach would result in quarterly module replacements, which would be a burden on the service and is not something we attempt. Replacing all modules at an authorized dealer costs around €11,000 for 9 kWh, including parts and labor.

We have access to almost new modules with 95% SOH, but even after replacement, we encountered the issue of a deactivated SME system, leaving the vehicle non-operational. This was our first encounter with such a problem. We were unaware that the owner had previously gone to BMW Graz “for diagnostics,” where, after diagnosing a faulty battery, they permanently deactivated the SME system to indirectly “force” a full battery replacement if he declines service. Once the system is deactivated, the only option is reactivation using the EOS or IMIB tools at an authorized service, just toolcosting €15,000.

After three months, we managed to reactivate the SME system, but this process, essentially pressing “ENTER” on the keyboard, cost an additional €1,000 to end user as EVC service. If you see the error code 21F1F6, it means the SME system is locked and prepare your “fuel saving”

It’s unbelievable how many requests we receive for hybrids. We can’t resolve all of them, nor is it our priority, but it’s disheartening how many customers have been misled by the automotive industry’s propaganda. While EVs are demonized, PHEVs are promoted as the perfect transition, yet when the maintenance costs arise, disappointment follows. The worst part is that, due to import incentives for hybrids, based on lower CO2 emissions, this worn-out PHEV junk from Germany with over 150,000 km is being imported into poorer countries in the hope of “fuel saving money.”

And Europe wonders why it’s losing customer trust in its vehicles and its global dominance in the automotive industry…
