We replaced battery twice and even had alternator checked by les schwab. What could be wrong?

After about 15 miles, the cluster beeps, and all that I explained above occurs.

I changed the fuil filter some one said it could be the throttle sensor or body

I own a 1999 VW Passat 2.8l V6. The check engine light has been coming on periodically, the code is P0118 (Engine Coolant Temperature Circuit High Input). I was wondering what steps I can take to resolve this issue.

Currently, the only symptom is that when I try to start the car the starter cranks normally, but the engine won't start. After a few tries of turning the key, it usually starts. Sometimes I wait a few minutes and try again. If the car has been sitting for a while (like overnight or a couple hours), the car starts fine and the check engine light doesn't even come on.

What's the worst case scenario? The car overheats without warning because the temperature gauge is broken?
The car has problems starting usually only when I am making frequent stops.

i have no power to electric front windows and peterol cover button, central locking not working. i have new battery and alternator and starter motor. 2 months ago.

Once the doors get automatocally locked they can be opened with the lock / unlock switch on the driver side door

Checked heater core temp.on hoses in & out and it seems same temp is hot evenly in and out.
with blower working heat-drops

can't find a heater control valve... What can it be????

The code was thrown again after I replaced the cat, both o2 sensors, plugs and wires. I have checked the SAIP and EGR valves. They all work.

I compared the o2 test readings between bank 1 and bank 2 for all four sensors. They are virtually identical. Difference of .1 volt.

When I changed the plugs, the plugs on bank2 where uniformly lighter than the plugs on bank one, which were uniformly browner.

Any ideas?
