Anyone ever experienced issues with this code? i've taken the whole intake off and made sure the maf sensor was clean and everything was seated correctly but it always comes on when a weird little jolt in the car happens at low throttle.

When you get a code use this to see the possible causes:

In this case you'll find:

If one of the two following faults present, then eliminate it first:
- 1F1A99 Monitoring sensor: Supply 3 (5 V): Voltage too high
- 1F1A9B Monitoring sensor: Supply 3 (5 V): Voltage too low.
If faults are entered for the following components, these must be processed first:
- Intake system, Valvetronic, VANOS, exhaust turbocharger, pressure sensors.
Check intake system for tightness.
Check crankcase ventilation connection to cylinder head cover.
Check tank ventilation connection to second inlet point.
Check hot film air mass meter for oil pollution.
- Replace hot film air mass meter.
