A "Tiny" Leak Almost DESTROYED This BMW 530e… Here's How We Saved It!

Описание: Imagine being quoted over £10,000 to repair your BMW 530e hybrid… only to discover the real fault was a failed AC condenser mixing coolant with the air conditioning system.

In this video, we diagnose a BMW 530e with:

HV isolation fault

AC failure

High voltage battery cooling issue

Hybrid warning messages

The cause? A coolant leak contaminating the AC circuit — a known weak point on the 5 Series.

Instead of replacing the entire system as recommended, we:
✔ Identified the exact failure point
✔ Cleaned and flushed the system properly
✔ Saved the AC compressor
✔ Protected the HV battery
✔ Repaired the vehicle for a fraction of the quoted cost

If you own a BMW 530e, 530e G30, or similar hybrid BMW, this is a must-watch.

Cooling is critical for hybrid battery longevity — and this fault can destroy your HV system if ignored.
