AdBlue removal, oil pressure increase Audi Q7

Our client's mileage limit was activated after which the engine would be blocked due to a fault in the AdBlue system. After returning from the business trip, we arranged for the removal, during which we additionally proposed increasing the oil pressure at idle due to its factory lowering, which could cause expensive engine failures in the future.

The contents of the EDC17 engine controller in VAG group vehicles cannot be read via the OBD port, which forces it to be removed from the vehicle if the customer has previously performed tuning or other modifications. In this case, the car was in factory condition, so we were able to use the so-called Virtual-Read, i.e. virtual reading, consisting in downloading the contents of the engine controller from Audi servers.

Thanks to this, the entire operation was performed in less than an hour via the OBD port without the need to remove the engine controller.
