VW stops pulling and smokes in spells when under a load
THe check engine light stays on and some times the coolant level light flashes. It smokes when you try to acelerate but if you floor it sometimes it will start pulling again. Sometimes you have to baby it. to get where you are going. THe person we got it from said that he put larger injectors in on it. I looked in the boook and where it showed the map sensor there was nothing there. Im open to any suggestions.

Re: VW stops pulling and smokes in spells when under a...
If its a diesel ??disconnect the pipe running to a valve that sits on top of exhaust manifold and connects to inlet manifold,if this works then dont bother repairing it as its mucho dinero.Just push a piece of twig down rubber pipe so its blocked off but it looks like its connected for the vehicle inspection.it will pass all emmisions tests no problem.

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.
you need to replace thermostat and radiator cap.look under hood around engine compartment.look for a radiator cap near radiator,add 50/50 antifreeze and water to coolant system to bring up boiling point.pure water will cause engine run hotter because water evaporate away,remove radiator pour coolant in the radiator until coolant stop dropping in the radiator now some vechicle pour coolant in the coolant overflow jug,pour coolant until coolant level stop dropping and the coolant level stay at cold full mark.start engie let idle few minutes, watch coolant level in radiator if coolant start dropping add more coolant, when coolant level stop dropping put radiator cap back on let engine idle until both top radaitor hose and bottom coolant hose get warm turn off engine wait until it get cool then take a large rag slightly open radiator just a litle at a time to keep from getting scaled.once radiator remove add more coolant if low,put radiator cap back on start the engine let it idle watch the temp gauge if temperature gauge going hot zone stop engine wait until cool then add more coolant,keep doing this until engine stop overheating going into hot zone and coolant level stop dropping,make the coolant overflow jug coolant level stay at full cold mark, dont let jug run empty if so air will get in the coolant system causing engine to overheat.
These problems may or may not be related. The Check coolant light means that the coolant level in your radiator is low. If you have checked it and it is not low, then the sensor is most likely defective. The low coolant sensor will not turn the Check Engine light on - even if the coolant really is low. There are many things that can cause the Check Engine light to come on. You will have to scan your Engine Computer to find out why it has been turning the light on.
I did have a problem on one of these cars one time where the Check Engine light was coming on and there were several codes for the Throttle Position Sensor(TPS) and the Manifold Absolute Pressure (MAP) sensor and the car ran really bad. The Check Coolant light was also on. After checking it out I found that the coolant level sensor was shorting out the 5 volt reference circuit (VREF) from the computer and causing the whole problem. Replacing the coolant level sensor fixed the car.
Check coolant level and top off with G12 VW coolant only or filtered water.
If you haven't replaced your water pump, chances are it could be the
original part (OEM). This use a composite material impeller similar to
hard plastic. They are prone to cracking at the shaft connection for
the pulley and doesn't spin with the engine. Replace it with an
aftermarket part which have metal impellers. I'd advice to invest on
replacing your timing belt at this time because the water pump is
behind the belt. Also keep in mind to use G12 only coolant (VW red
coolant), these are phosphate free keeping the system cleaner. Your A/C
when switched on automatically activates the fan to lower engine temp
when the compressor adds extra loads to the engine.
sounds like a bad connection somewhere check your ground from the engine and body, to the battery. check all connections to all sensors in the rad and the coolant bungs, get them squared away best as possible.
if that's not the remedy check coolant level if the fan switch is not submersed in coolant it will not turn on the fan. and the same goes with the temp sensor the level may be right at the sensor but below the fan switch. If the coolant is low top it up. check it again in a couple days.
if the coolant in low again check for white smoke out the tail pipe. depending on your technical skills you may at this point want to bring it to a garage for leak down test and compression test. Good luck!
Does the smoke occur all the time? If it is present just after start up and then goes away, it could be no problem at all. There is always some condensation in the exhaust at start up. It is more noticeable in cold weather.
However, if it is there constantly, and you are losing coolant, it could mean there is a headgasket problem. Watch your coolant level and watch your temperature gauge. If the coolant starts disappearing, and the car starts overheating, stop it immediately and get it to an auto repair shop. Driving a car with a bad headgasket can cause major engine damage.
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.
