Our certified technicians document the diagnosis and provide recommendations that prioritize long-term value and lower lifetime ownership costs.

2017 Volkswagen Passat Check Engine Light Codes

Common check engine light codes for the 2017 Volkswagen Passat include oxygen sensor faults (P013x), catalytic converter efficiency codes (P0420), and misfire codes (P030x). Each code corresponds to a specific system and carries costs if left unaddressed: oxygen sensor failure can reduce fuel economy and lead to higher emissions; unresolved misfires can damage the catalytic converter and lead to costly replacements; and catalytic inefficiency can cause failed emissions tests. At Larry H. Miller Volkswagen Lakewood in Lakewood, CO our technicians interpret codes in context — some codes are symptoms rather than root causes — and we map out the most efficient, cost-effective repair path. Using genuine parts and factory repair procedures minimizes the chance of recurring issues and often results in lower overall costs than multiple independent-shop visits. We provide clear estimates, explain immediate and long-term savings from prompt repair, and offer service financing for flexibility.
