Last week my car broke down on the parkway. I found out the water pump had broke. Had timing belt and water pump replaced. Since then, having a problem when starting the car. It's ok when first starting for the day, but once I am driving and then make a stop, when I turn on the car again it starts for a few seconds, then cuts out, then goes back up again. Also when driving 50 mph or more it stalls a bit sometimes, but not all the time.

I went back to the mechanic who had replaced the water pump and timing belt. He said the air temperature sensor was broken, and it might have given mixed signals to the engine. He replaced the air temperature sensor, but the problem with starting the car is still there.

Do you have any ideas on fixing this problem? I am not confident about the mechanic I'm using. I paid an extra $80 for the air temperature sensor and it hasn't fixed anything. Thank you for any answers you can provide.

I just replaced the sensor and the heat started working just fine now I have no heat again but it blows out cool/warm air

Will turn off eventually while driving. No problems From passenger door.

Fan don't come on could it be the thermo sending unit at the thermostat housing that needs to be replaced? lost as to why the fans won't come on or why it keeps over heating? have not checked the fuses could it be that simple?

All doors will lock with either door switch or remote but only drivers door functions correctly. I place all door locks in open position. The door switch will lock all but only opens drivers door. I replaced door switch assembly, no help.

Have not driven truck very much this past couple of months, I start it every week and let the thermastate heat up then turn it off, last week took it golf course up the street and everything was great, this week I move it down the drive way and I noticed that the brake pedal whent straight to floor, never had this problem before. This truck has never given me a problem like this. One week good, no driving, next week no break preasure at all. Filled brake fluide to max on small container under hood and still no preasure. What could be the problem.....Anyone
Thank you.

power was disconnected and now I need a code to reset

Interior light shut off after a half hour, I want to replace the switches in the door latch that controls the interior lights, how do you get the switch out of the door?

The transmission has a small leak and the dealer is saying it could be just a seal or it could be a cracked transmission case. I am trying to figure out what the cost of replacing the transmission case would be worst case. Plus is a cracked case under warranty (5-year Powertrain)?

Detailed instructions on ignition module removal, and installation. Please

I have no noticeable oil leaks, there's never any oil spots under my vehicle on the garage floor. I do find very black splatter behind my vehicle after idling for a time though. I'm going through about a quart of oil every two tanks of fuel, so about 700 miles or so. Gas mileage is good, sometimes great. Is this likely that the piston rings are not sealing well anymore? I have over 300k miles on the vehicle but still in very good condition for that many miles. Have never had a valve adjustment as I have been told that may cause poorer seating rather than better at this point, but I wonder if that could be causing leakage. My spark plugs look like they are burning clean, though a couple looked overly black after 100k miles.

Beetle. What's the cost if the motor must be replaced?
