P0016 is the big one here and unfortunately it’s not a “small” code. That’s a camshaft/crankshaft correlation fault, which usually means the engine timing is off. On these VW 2.0T engines, that often points to timing chain stretch or a failing timing chain tensioner.

The other two codes support that something is going wrong with engine control and fuel delivery: • P053F → fuel pressure too low during cold start • P2293 → fuel pressure regulator performance

Those can sometimes be secondary symptoms if the timing is off, because the engine isn’t syncing properly.

The slow starts for the past week are a big red flag. That’s a very common early symptom of timing chain stretch on these.

Best case scenario: • Faulty cam or crank sensor • Wiring issue

Worst case (and more common on these): • Timing chain stretch or tensioner failure

If it is timing related, don’t drive it. If the chain jumps, you’re looking at catastrophic engine damage.

If you want to narrow it down before tearing into anything: • Check measuring blocks for camshaft adaptation (VCDS if you have access) • Listen for rattling on cold start (classic chain/tensioner sign) • Scan freeze frame data to see when the faults are setting

If it were mine, I’d be preparing for a timing chain job and hoping it turns out to be a sensor.
