Question about 2005 Volkswagen New Beetle
WHILE DRIVING @ ANY SPEED THE VEHICLE LOSES POWER AND THEN STALLS ,REPLACED THE MASS AIR FLOW ...STILL DOE THE SAME THING BUT WHAT I HAVE NOTICE IS THAT IT IS GETTING WORST IF THE CAR HAS LESS THAN A HALF A TANK OF GAS , RIGHT BEFORE IT STALLS AS I AM LOSING POWER , IF I WERE TO COAST IN NEUTRAL THE CAR WILL NOT STALL
COULD THIS BE A TURBO PROBLEM? TRANSMISSION?

SOURCE: loses oil very quickly
If oil is truly coming from between the engine and trans then seal replacement didn't work or one of the soft plugs in the back of the block are leaking OR the block is cracked in this area (I HAVE seen this happen!)... did you look closely at the source of this oil? Are you sure that it's not the oil cooler seals (this is inside the fan shroud and hard to diagnose, but will will result in total oil loss within minutes!) Replace the oil, put the bug in the air, run it and watch the flow of oil while wiping with a rag to be sure of the source. If it's truly coming from between the block and trans, then pull the motor back out and thoroughly inspect with flywheel removed... also check that all the nuts and bolts holding the case halves together are tight... Hope this helps...;-)

If it was the mass air flow sensor, you will have a check engine light. The small rubber hoses connected to/from the mass air flow connector might have come loose or have a crack, which will cause compression to be too low. Check there before replacing the maf sensor.

I had a similar problem and the mechanic diagnosed it as a problem with the ignition coil. So you might want to get that checked.

You have a bad coil pack, they usually crack from age and heat. It's best to replace them all. Check for a VW recall on this item.

Would really need more details on the vehicle. Petrol / diesel etc
Is the engine management light on? Are there any fault codes?
Power lose while driving is most likely to be caused by the mass air flow meter, leak at a vacuum or intake hose, turbo leak etc.
More details please........
