BMW G30 330e Hybrid from Switzerland with a charging fault and an estimate of €18,000 – there’s no way it really costs that much or that we can’t fix it.
The issue was a PTC coolant heater fault, KLE failure, and EME electronics failure.
Error codes: 21E720, 030EC1
After reviewing the EPC catalog, the authorized service, following their guided diagnostics, does indeed replace the EME, PTC, and KLE.
- EME: €7,000 + VAT
- PTC: €1,000 + VAT
- KLE: ~€1,000 + VAT
- Labor: ~€2,000
Total OEM repair: ~€14,000
The root cause of the failure was a short circuit in the PTC heater, which damaged the other components.
If we consider that the high-voltage battery typically fails around 100,000 km, that’s another €9,000 + VAT based on OEM pricing.
Other potential costs include:
- Engine: ~€11,000 + VAT
- Transmission: ~€14,000 + VAT
We fixed the vehicle for a third of the cost, but whoever owns these vehicles — you’re truly brave, and better prepare a mortgage for “regular maintenance.”
IMPORTANT: BMW hybrids with battery faults are not being accepted for repairs until further notice, due to supply chain issues — new battery modules are unavailable!
