2012 VW Jetta Transmission Issues: P2432, P0491, P0721 Codes - Estimated Repair Cost and Complexity

Model: 2012 VW Jetta Fault Code: P0491 Posted: 2019-12-15 12:04

I purchased a 2012 Volkswagen Jetta in 2016 and have recently encountered multiple engine diagnostic trouble codes. My main concern is estimating the labor cost and technical complexity of repairs—could this involve a full engine disassembly? Based on current symptoms, I'm concerned that the vehicle may not shift into gear properly when cold or warm. If the engine revs to 300-3500 RPM, it will engage but with very limited power, making the car undrivable. Diagnostic Codes: P2432 (Fuel Pump Control Circuit) P0491 (Exhaust Gas Recirculation (EGR) System Performance Issue) P0721 (Transmission Input Speed Sensor Malfunction) I've noticed that some codes are listed with a dollar sign prefix—does this indicate an error in formatting or is it just a placeholder? I'm wondering if these issues are common and whether there's any reliable guidance on repair scope, labor estimates, or potential fixes. Any insights would be greatly appreciated.
