Project Details:

At Euro Auto Tech & Smog, our certified technicians recently completed a five-day project on a Mercedes-Benz G 550 in La Mesa. The vehicle’s check engine light had triggered codes P0456 and P0455, leading us to a thorough diagnostic investigation. We traced the problem to a cracked fuel filter mounted directly on the gas tank—a rare but critical issue causing fuel vapor leaks.

Sourcing the right part became our next challenge. The specific fuel filter was on backorder at the dealership, with a two-month wait time due to limited supply and shipment from Germany. Refusing to let our client wait, we located a new-in-box OEM fuel filter and expedited shipping.

Our team completed the installation efficiently, ensuring all issues were resolved and codes cleared. The Mercedes G 550 was back on the road, performing at its best, and the customer couldn’t have been happier.
