Has the timing belt or chain ever been replaced?

Did you check timing belt marks?If OK-change spark plugs and...CP sensor/crankshaft position sensor/

the timing belt or chain...which ever you have...
a transmission oil change...every 3,000 miles or 3 months you need an engine oil change...so check that...
the spark plugs and wires,change the rotor if it hasn't been changed for a while...and check if the radiator needs flushing...
Good Luck!

The A/C in my 2006 Passat 2.0 T is not working consistently. It seems to quit giving cold air when the outside temp is the hottest. It sometimes works fine until the engine is warmed up-then starts blowing hot air. Any Ideas?

YOUR CORRECT IT IS A COIL PROBLEM.... DO A REGULAR 6 MONTHS TO A YEAR TUNE UP AND YOUR CAR WOULD RUN PERFECT....

CHECK ENGINE OIL LEVEL SOUND LIKE LOW OIL LEVEL.CHANGE OIL IF IT HAS BEEN OVER 3000 MILES OR OIL LOOKS DIRTY CHANGE IT.IF OIL CHANGE DONT HELP HAVE OIL PRESSURE CHECK TO SEE IF OIL PUMP GOING BAD OR YOU HAVE A FAULTY OIL PRESSURE GAUGE.

1998 VOLKSWAGEN PASSAT 1.8L 4-cyl Engine Code AEB/AWM Turbo
Models with 1.8L Engine codes AEB, ATW, AUG, AWM only
use engine oil that is formulated to meet
Volkswagen oil standard VW 502.00
(with viscosity of SAE 5W-40, 5W-30 or 0W-40).

CAPACITIES: Engine, with filter..........3.5 liter To prevent overfilling during oil changes, add 0.5 liter
(0.5 quart) less than capacity shown, start engine, let run
until engine operating temperature is approx. 60 °C (140 °F)
, switch engine off, wait 3 minutes, check dipstick,
fill to full mark as indicated on dipstick (may be more or
less than 0.5 liter (0.5 quart) depending on model).

As for the sludge question, I add Marvel Mystery Oil around 600 miles before i do my oil change. This will clean out the oil pick up screen and oil journals through out the engine, I do this on every oil change and i have over 356,000 miles on my engine. Oil and filter changed every 3,000 miles intervals. Good luck and hope this helps.

sounds like a faulty wire,possible on the ignition circuit or faulty battery leads.

I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.
