CUSTOMER REQUESTS – CHECK ENGINE LIGHT
FOUND:Diagnostic Summary Report Vehicle: 2016 Mercedes-Benz GLA250 2.0L Base Fault Code: P052E – Crankcase Ventilation System Performance. Code Description: This DTC indicates that the engine control module (ECM) has detected a performance issue within the Positive Crankcase Ventilation (PCV) system. Specifically, the switchover valve is not regulating crankcase pressure correctly, which can lead to rough idling, decreased fuel efficiency, and increased internal engine pressure. Visual Inspection & Technical Findings: Oil Intrusion: Motor oil was found inside the electrical connector of the PCV switchover valve. This indicates an internal seal failure, which can lead to signal interference or potential damage to the engine wire harness. Component Failure: A physical breach/rupture was identified in the PCV vent valve, compromising the system's ability to manage oil vapors. Intake Leak: Visual inspection confirmed cracks and ruptures in the air intake hose connecting the air filter housing to the turbocharger. This allows unmetered air to enter the system, negatively impacting turbo performance and air-fuel ratios. Recommended Action: Replacement of the complete PCV vent line assembly and the damaged turbo intake hose is required. It is also recommended to clean the electrical harness connectors to prevent oil migration.

CUSTOMER REQUESTS – CHECK AND ADVISE CHECK ENGINE LIGHT
FOUND:Diagnostic and Service Summary 1. Seating System (Interior): Finding: Confirmed loose/fallen springs at the base of the seat. Root Cause: The rubber retainers that act as structural supports have degraded and crystallized due to age, breaking into pieces and leaving the springs without tension or support. Status: Replacement of the seat support retainers is required. 2. Engine Management (Check Engine Light): Initial Diagnosis: Fault codes related to the Secondary Air Injection (AIR) System were identified. Repair Performed: Found cracked and degraded vacuum hoses located above the valve cover and beneath the plastic engine cover. These hoses were repaired, and subsequent testing confirmed the Secondary Air Injection system is now fully operational. New Finding: During the post-repair road test, the vehicle’s computer triggered new codes for a "Lean Condition" (Poor Mixture). After sealing the initial vacuum leaks, the system is now detecting unmetered air or a fuel delivery deficiency in another area. 3. Vehicle Release Status: Pending: Diagnosis of the "Lean Condition" requires additional diagnostic time for pressure, flow, and vacuum leak testing. Customer Decision: The customer did not authorize the additional time required to complete the diagnosis and elected to take the vehicle. Disclaimer: The vehicle is being released with the Check Engine Light ON due to the lean mixture fault. This condition may result in poor fuel economy, reduced engine performance, and potential long-term damage if not addressed.
