2014 VW GLI P0016, P0341, U0121 Fault Codes - Won't Start, No Fire, Turbocharged Engine

Model: 2014 VW GLI Fault Code: P0016 Posted: 2016-08-04 03:52

We own a 2014 Volkswagen GLI and are experiencing a starting issue. The vehicle cranks but does not fire. After scanning the engine, we received diagnostic codes P0016, P0341, and U0121. This is a gasoline-powered, turbocharged engine with only a powertrain warranty in place. We've searched online for camshaft position sensor replacements but have found conflicting information about part types. Given that the closest authorized VW dealership is approximately 40 miles away and we lack tow service under warranty, we're attempting to resolve this issue ourselves. What are the most reliable steps to diagnose and fix these codes? Can P0016 or P0341 be resolved by replacing a camshaft sensor, or do they indicate deeper engine problems such as valve train failure?

I recommend contacting your local Volkswagen dealership and transferring the call to their parts department. Once connected, simply ask for the price of the required sensor. Provide them with your VIN so they can look up the exact part in their database and give you the correct part number. Then, share that number with them so you can purchase it directly. I’ve used this method several times—this helps me get accurate pricing and often allows me to find the same part on online retailers at a lower cost than the dealership. Best of luck with your repair!

If you're new to purchasing vehicle parts, I recommend checking out trusted online retailers like PartsGeek.com or RockAuto.com. These sites offer reliable VW-specific components and often provide better pricing than dealerships. Let me know how the repair goes—happy to help further if needed.

Thank you for the advice. Ultimately, I had the vehicle towed to a local mechanic who performed a diagnostic test and found no compression in cylinders 1 and 2. A scope revealed that both valves were not moving—indicating mechanical failure. The engine is now at the dealership, which has confirmed it's due to a broken cylinder head. Unfortunately, this issue isn't covered under warranty unless I can provide all my oil change receipts from the past two years.
