Recently BMW issued a recall involving the E70 BMW X5, with 1.540 units being called into the shops for fixes.
The problem discovered by the NHTSA put the fuel filter heater at fault, and while no incidents cause by it were registered, there are certain risks.
While at first the problem seemed to only affect the 1.540 units, now new reports came in, dragging even more diesel BMWs into the spotlight. The affected models include the E87 1 Series (555 units), the E60 5 Series (321 units), the F01 7 Series (17 units), the E83 X3 models (812 units), the E70 X5 (1.395 units) and finally, the E71 X6 (43 units).
These models were discovered to be at fault after BMW Australia decided to look in their own back yard for the issue reported in the US for the E70 BMW X5. Apparently it is the same as with the X5, the fuel heater might remain active even after contact was taken off. The fix is the same, too, with BMW set to replace the component altogether, and again, free of charge.
