Sounds like it may be running a bit lean - do basic checks for air leaks in the induction system (such as leaking manifold gasket, loose hose fittings to air flow sensor etc).
Condition of HT leads also worth a check.

Low fuel pressure will cause many of those codes to set.
Should have around 3.5bar pressure at idle and full throttle.
Check to see if VW has a recall on the ignition coils. They are cheap to replace however.....you will need your VIN# when you call.
Alternator problems can also trip codes . Check for a/c ripple at BATT + on Alternator...no more the 0.05vac allowed.
Valve train noise common complaint. ...often due to lack of oil services and/or incorrect oil type.
All 1.8T engine will clatter on start up one time or another and is considered normal as long as it goes quiet after 2 to 5 seconds at idle.
You should have synthetic oil in the engine.
P0012 is often timing incorrect. ...check timing belt at tdc.
These engines need a timing belt every 50,000 miles not the 100,000 miles VW suggests. Belt failure is catastrophic.
Transmission codes often corrosion in loom connections under battery. These need checked and cleaned with a solution of STABILANT22A applied to the pins.
If a scanner is available clear the codes and drive for 40 miles or so and recheck for codes. Transmission codes are not always due to transmission faults. They need 200 miles to re adapt after batter replacement or power off.
ROSS TECH site has lots of info' and a scanner program for your lap top.

P0172 - System Too Rich (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0175, and in fact your vehicle may show both codes at the same time.
Symptoms: You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire. This is the next code explained.
Causes: A code P0172 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem
Possible solutions include:
* Inspect all vacuum and PCV hoses, replace if necessary
* Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
* Inspect fuel lines for cracks, leaks, or pinches
* Check the fuel pressure at the fuel rail
* Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
* Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)
P0301 - Cylinder 1 One Misfire Detected
A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.
Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present
Causes: A code P0301 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Keep in mind that the "misfiring" are not only for bad O2 sensors, check the other componentes that I tell you before.
Keep us updated.

Hi Paul, Have you had a fault code relating to the knock sensor? That sensor controls ignition timing which can have a relationship to the fault codes you report? Regards John
