My car has been "stuttering/missing" when accelerating, usually when going up hill. Then suddenly while changing from fourth to fifth gear there was a definite but subtle change in the way the engine was running not the same "stuttering/missing" previously experienced and when I stopped the car the engine was running extremely rough, so much so that the car was shaking.
Do you
have the same problem?
Yes
No

Welcome to 2CarPros.

The code you provided is related to timing, and specifically to the camshaft adjustment valve. I suspect that is may be faulty, but would require diagnostics to determine.

Before I can provide specifics, I need to know the engine size and if it's a gas engine or diesel. Here are directions for testing the valve on a 1.8T, but I need conformation from you on the engine size.

The attached pictures correlate with the directions.

WITH GENERIC SCAN TOOL
Camshaft Adjustment Valve (Vehicles With Engine Code AUG, AWM), Checking

Function
The camshaft adjustment is load- and RPM dependent. The electrical valve for camshaft adjustment switches oil pressure onto camshaft adjuster (mechanical adjustment mechanism), which adjusts the camshaft.

Recommended special tools and equipment
- V.A.G 1526 portable multimeter or V.A.G 1715 multimeter
- V.A.G 1594 connector test kit
- Wiring diagram

Test requirements

pic 1

- The respective fuses of the Valve -1- for camshaft adjustment -N205- must be OK
- Fuel Pump (FP) Relay -J17- must be OK, check
- Battery voltage must be at least 11.5 volts.
- All electrical consumers such as, lights and rear window heating must be switched off.
- Parking brake must be engaged or else daylight driving lights will be switched on.
- If vehicle is equipped with an A/C system, it must be switched off.
- Ground (GND) connections between engine and chassis must be OK.
- Ignition switched off.

Test sequence

- Measure resistance between terminals of the respective valve for camshaft adjustment.
Specified value: 10 to 18 ohms

If specified value is not obtained:
- Replace the valve for camshaft adjustment.
- Erase DTC memory of Engine Control Module (ECM). See: Computers and Control Systems > Scan Tool Testing and Procedures > Scan Tool Connecting and Initial Checks
- Generate readiness code. See: Computers and Control Systems > Monitors, Trips, Drive Cycles and Readiness Codes

If specified value is obtained:
- Connect test box to control module wiring harness. Connect test box for wiring test.

Pic 3

- Check wire between test box socket 115 + 2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max: 1.5 ohms

- Check wires for short circuit to B+ and Ground (GND).
Specified value: Infinite ohms

- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.
Wire resistance: max: 1.5 ohms

If resistances and wires are OK:
- Replace Motronic Engine Control Module (ECM) -J220-.
