Most of the Diesel BMW cars past 2010 are equipped with the AdBlue injection system, which tends to fail from the level sensor going rogue. If you topped up your AdBlue tank and the car still says “No Start In 400 km”, your level sensor is no longer operational.
There are two ways of solving the issue: Complete tank replacement (around $6000) OR permanent system disablement by EuroSurgeon for a fraction of that cost. We’ve completed this service for over a thousand happy customers, so it’s fair to say our EuroSurgeons know this job inside and out!
