check your sensors 1st,all sensors must be good
if all sensors are working good than check your engine firing sequence,some times happens when sequence was wrong,
check your exhaust and carborator tuning pin that creates the batter combination for firing in bore for batter performance & less emitions ,so check is it ok or not than go to your nearest service center that havad certified mechanics,
till you read this you had solve this problem definatly,

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

SOURCE: Removing VW polo 2005 battery?
Removing a battery from a Beetle is a bit complex and tricky. I just changed the battery in a 2003 2.0 Beetle. However, the process is very similar in a TDI Beetle. You will need more than your standard generic tool set in order to complete this task. Your tool list needs to consist of a pair of pliers (prefer locking type), a # 20 TORX head screwdriver (You will also need this if you ever plan on changing the Beetle's internal dash pollen filter for the A/C. ), a 10 mm and 13 mm sockets, a long extension and a wobble or universal to allow flexibility in tight spaces, an allen socket for removing the power steering reservoir, and a small adjustable wrench or a 10mm to remove the battery cables. If you are changing the battery you might as well buy a new Air filter since you will need to remove the air box in order to replace the battery. If you do change the air filter you will need a phillips head screwdriver.
1. Pop the hood.
2. Remove the two 10 mm bolts that hold down the air filter box.
3. Undo the clamp that holds the large tubing to the air box using your pliers. Move the tubing away from the box.
4. Unclip hose attached to the back of the air box near the large hose (under it).
5. remove the small breather hose from the air box.
6. Pull air box up and out.
7. Remove snap on cover from top of battery.
8. Remove small snap on wiring cover from back of the battery covering.
9. Unbolt power steering reservoir (next to battery case).
10. Disconnect the battery cables. Positive side first.
11. Remove the 13 mm bolt at the base of the battery along with the hold down clamp.
12. Pull the top wiring away from the battery case and then slide the battery towards the engine.
13. Remove the plastic battery case.
14. Remove the battery

this a map sensor, probably just need the sensor replaced, it measurese intake vaccum and adjusts air/fuel mixture accordingly

Testimonial: "MANY THANKS TO HONDABOY 47. SPOT - ON. PROBLEM SOLVED!"
from the exhaust manifold you have a pipe going down to the first box(cat converter),the lambda probe(o2 sensor) is between these two.looks like a tube sticking out the side.
