Question about Volkswagen Passat

1 Answer

1999 VW Passat 6cyl Turbo 20valve: 1. Engine coolant temperature/level light is blinking? 2. Engine coolant level is a little low so, I'm going to add G12 from the deal and see if that solves the problem. 3. Engine temperture gauge works intermitently? Is there a sensor I could because the car is running fine? Thank you, Mike

    Thanks for the quick response. I tried to follow the hose, but it's difficult to do. I'm no mechanic but I'm very handy and do most of all my work especially the easy tgings.....Is the sensor located at the top of the engine or the bottom? I noticed a sensor above the oil filter is that it?



    Thanks again!

Hi Mike!

If the coolant level is low, adding coolant will take care of the light on the inst. panel. The coolant temp. sensor is located on or very close to the thermostat housing, just follow the hose from the radiator to the engine, the part where the hose connects is the housing and the thing screwed into it with an electrical plug in it is the temp. sensor, check for a tight connection and broken wires. If sensor needs to be replaced, wait for vehicle to cool down, unplug electrical plug and using a long socket remove sensor. to install, reverse instruccions.

Good Luck!!

    The sensor by the oil flter will be the oil sensor. The temp sensor is on top of the motor and very close to motor end of the hose. somethimes mounted on the thermostat housing others in the intake maniful.



    If you still have problems finding it, go to your closest AuoParts store and they will pinpoint it for you.



    Good Luck Buddy

Where should the coolant level be for a 2003 vw Passat turbo wagon?


Between the low and high level indicator lines printed in the bottle. If none visible, half or 3/4 of bottle is good.

1999 VW Cabrio dash light


Obviously it's temperature gauge light. Check for coolant level first. Then check for coolant leak. If coolant is leaking out of your car, the lower coolant levels in your engine will cause it to overheat. If you have your heater on and it starts blowing hot air instead of cool, your engine is low on coolant. This will cause to flash a warning light on your car's dashboard.

Temperature light came on 2002 VW Passat wagon backing out of garage today, slight burning smell. Returned after 2 miles. Have experienced this smell on and off since oil & filter change several weeks...


You can see the coolant level by looking through the opaque round coolant reservoir. It should be just over the middle. There's a line indication proper level. Orange Dexcool meets the VW specification and is generally available. The rear coolant flange can warp and seep over time and leaks onto hot parts. That's probably why you smell it.

VW passat coolant warning light on


There's a level sensor plugged into the bottom of the coolant reservoir. Unplug it and clean the contacts with electrical contact cleaner. If that doesn't do the trick, replace the sensor.

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Where is the temperature sending unit on a 1999 VW Passat located.


VW Passat & Audi A4 1990-2000

Motronic System
The Engine Coolant Temperature (ECT) sensor is mounted in the water outlet on the back side of the head. If you vehicle still has a original VW part it will be black in color with a four terminal connector. This device signals the engine management system with the current coolant temperature, the ECU takes this information and uses it to control other such circuits as the idle speed, knock control system, oxygen sensor circuit, exhaust gas recalculation, and fuel tank venting. It is also important to note that if at any time ECU does not receive a signal from the ECT it will substitute a value of 176°F (80°C).

VR6
The Engine Coolant Temperature sensor is mounted in the thermostat housing. The body of the sensor will be blue and the sensor will be blue and have two terminals if it is an original factory VW part.


The engine coolant temperature gauge uses a heat sensitive sending unit to transmit an electrical signal to the gauge. The sending unit is a heat sensitive variable resistor that is located on or near to the cylinder head and threads into an engine coolant passage. The sensors are a Negative Temperature Coefficient (NTC) type. As the temperature increases, the electrical resistance of the sensor decreases. As the coolant temperature changes, so does the resistance of the sensor. The gauge is calibrated within the operating range of the sensor and interprets the resistance value to display the coolant temperature.On models produced prior to 1994, the engine coolant gauge temperature sensor is a single wire terminal sensor.

Beginning with model year 1994, the engine coolant gauge and the Engine Control Module (ECM) temperature sensors were combined into one sensor with 4 terminals. The basic operation remains the same in that their resistance decreases as the coolant temperature increases, however the actual resistance values of the 2 sensor circuits are different. The electrical connector of the 4-wire terminal sensor (1 and 2) is keyed to prevent improper connection of the sensor's electrical circuit.

WARNING When trouble shooting electrical components, always consult a wiring diagram for the particular year, make and model to ensure proper test equipment connection and diagnosis. Failure to use suitable test equipment and testing methods could permanently damage the electrical component(s).

1999 VW Passat low idle


replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.

2004 VW passat not heating


COLD AIR WHEN IDLING COULD BE...
1) Low on coolant - the most common reason for this heater problem. Make sure your coolant level is full.
If the level is low, it could be because the radiator cap is not sealing well or it could also be a cracked overflow container (hot coolant that bleeds out of the engine and drops to the street so you never see the puddle on your driveway).

2) An air-lock in the coolant system - it needs to be burped. Park your car facing-up the steepest hill you can find. Remove the radiator cap a (be careful - best to do when engine is cold) and rev engine to 2000 RPM for 60 seconds - hopefully the air will burp out the cap. Top it off with 50/50 antifreeze.

3) A disconnected or cracked vacuum line. I've heard about this one but never investigated.

ABS and coolant are unrelated unless there is a problem with the ECM (engine control module) or instrument panel. Is the red coolant warning sign for coolant level or temperature?

With ABS if there is any failure with any brake electronic component (sensor, motor, or fluid level etc) the ABS will shut down completely and flash the light. If the light is on or flashing the ABS is non functioning.

I need better information on the coolant and ABS to give better information.
