SureTrack Real Fix: Exhausted MINI

Real Fixes from the SureTrack® expert information resource are documented issues from actual shop repair orders and community discussions. Read on to see how SureTrack can help you correct issues that are not easily diagnosed using OEM information alone. SureTrack is currently available free with the purchase of a current Snap-on® diagnostic software version.

Diagnosing this Mini is not exhausting when using the Triton D10! The Scanner and lab scope were used to electronically prove the failure, and was backed up with the visual inspection. Another fix successfully completed.

Vehicle
2013 MINI R55 1.6 Petrol GB

Title
283D, 2845, Replaced Exhaust Valve Timing Control Solenoid

Complaint
The customer states the check engine light is on.

Cause
Connected a scan tool and found codes: 283D – VANOS Exhaust Adaptation Stop and 2845 – VANOS, Exhaust Actuator Movement. With the key on, engine off, used a multi-meter to check for the presence of voltage in the exhaust valve timing control solenoid and found voltage was present. Used the multi-meter to measure the resistance of the exhaust valve timing control solenoid and found the measured resistance was within specifications. Backprobed the exhaust valve timing control solenoid, ran the engine, and monitored the solenoid control signal on a lab scope while varying the engine speed. Determined that the frequency of the exhaust valve timing control solenoid signal increased as the engine speed was raised, which indicated the powertrain control module was attempting to control the solenoid. Removed the exhaust valve timing control solenoid to perform a visual inspection, and found it was clogged with carbon, which caused the solenoid to seize.

Correction
Replaced the exhaust valve timing control solenoid, cleared codes, performed a road test and verified the vehicle operated properly.
