Question about 2000 Volkswagen Jetta TDI

2 Answers

EPC light I just got my 2003 Jetta (2.0 engine) back from the dealer for an overheating problem. They replaced the water pump and temperature sensor but when I picked it up the EPC light was on. Any idea what would cause this and can a code scanner reset it? Thanks

This sounds like a "brake light switch" failure in a 5 speed manual transmission car. Please tell me your car has a manual transmission. A scanner, or code resetting tool will not fix this problem. I'm surprised that a dealer would allow this to get out the door without telling you that this car qualifies for a "campaign," or "recall" replacement of the brake light switch under the "N4 program" guidelines. In fact, this program is actually called the "N4 campaign." Good luck.

Disconnect the battery, re-connect..Drive for 150 miles, if no light after that no problem...
if light returns, take it back to repair

I have a 2003vw jetta the epc light is on and the will not come out of park nor the stop lights come on,I have already changed the brake switch and still won't work..


EPC light should have nothing to do with the shift interlock,(EPC is traction control) should be a small cap or plug on the console, near the shifter that has the interlock disengage button,usually done with a key,check shift interlock in the owners manual.

What is the problem with my 2003 VW Jetta 2.0 overheating?


It may also be the temperature sensor.
Not knowing your model, if it uses both a belt driven and electric fan, the electric fan (or its sensor) may have failed.
Turn on the AC to see if the electric fan will cycle as it should since this is used (in most vehicles) for engine cooling if the main fan isn't adequate whether AC is in use or not.
On high mileage engines if distilled water was not used instead of tap water (along with coolant), the radiator core can eventually become clogged with calcium deposits. .

2003 VW Jetta 1.8T Temp Guage/False Overheating Issue


your car is cooking!!!! if your heater starts to blow cold air its got an air lock in the system and need to be blead out to get this air out of the water jaket in the engine sounds like your gauge is working fine to me, its screeming at you to stop! as its over heating the engine, look under your hood for the water hoses you should find a hose with a kind of nut or screw in it at the higest point on a water hose, this is the bleed point, fill the rad up with water and turn on the heater to hot only do this when the engine is COLD undo this screw or nut start the engine up and watch the water flow out this bleed point till there is no more air coming out with the water, keep the rad full of water and you dont need to put the rad cap back on till the air has been bled out but keep the rad full of water all the time after all the air is out refill the rad or top it up put the cap back on and run the motor it should not show as hot as it was and the heater should work just fine

I have a 2003 VW Jetta 1.8t that is overheating. Replaced the thermostat, temp sensor, water pump. Fan will run when AC is on, but haven't had it running in hot enough weather to see if the cooling fan...


Assuming engine tune / mechanical condition is not the cause of the overheating:-
Ensure cooling fan is cutting in at the appropriate engine temperature - check operation of the fan controlling relay,
Ensure fan switching control temperature sensor is serviceable,
Ensure cooling system is filled properly, taking care to bleed out air where necessary,
Ensure coolant pressure cap is of correct rating and in serviceable condition,
Check coolant hose on suction side of waterpump is not softened and collapsing at engine revs above idle,
Ensure radiator core is not blocked or cooling airflow inhibited by insects etc.

Overheat


Hi,

In my country, most overheating issues on Volkswagen models are resolved by:
  • entirely removing the thermostat (not applicable in cold regions);
  • wiring the fan to switch on once the engine is running (with or without the A/C or heater being turned on);
  • replacing the radiator thermal switch for the fan to a lower temp.
As to the "check engine light", the correct procedure would be to have the engine management computer scanned for fault logs. The error codes would point to the probable area(s) to check/clean/replace.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
