An electric fan will stay on even if your engine is off. It does that to cool your engine. This itself should not cause your check engine like to come on. Hope this helps you.
Locate the cooling fan relay module, drivers side below radiator. It is stuck closed, replace with new module. This will solve your problem.Locate the cooling fan relay module, drivers side below radiator. It is stuck closed, replace with new module. This will solve your problem.

If you are talking about 1.4 TDI model year 2014+ Then the blower u hear is tha cooling fan that keeps running for some seconds after shut engine off due to the fact the DPF ( exhaust filter ) has gone into regeneration to burn all trash and due to high temperatures generated by the engine's rich fuel mixture the fan has to work for a while !!
Normal !
Have your battery tested. If the fans ran all morning, too cool down your van it probably killed the battery. Also keep an eye on your temp gauge, and make sure it's not overheating. The temp sensor for the fans could also be faulty ; causing them to run longer than they should when you turn the van off.
look at connection to your starter. sometimes the positive cable works loose due to driving conditions. I had same problem with a Suzuki it only did it in cold weather but I ended up replacing the starter.
I"m not sure what the problem is, this sounds like the engine light is coming on because its overheating and you replaced the airpump and alternator and now you thinks it is the thermostat. if this is correct then yes replace the thermostat and also check the fan clutch, when engine is hot the fan should not spin freely. and last are you sure the engine light is on due to it overheating, if it is due to overheating then check fan clutch and replace the thermostant
That is what it is supposed to do. There is a temperature switch that opens and closes as the coolant reaches certain temps. When it reads those temps it turns the fans on or off as needed. Your fan circuit is separate from your ignition to allow it to keep the engine cooled down after you shut the car off. This prevents possible damage to the engine due to heat. Today's engine have a lot more aluminum in them and it is affected by heat more so than the old cast iron engines. It is more noticable in warm weather because things heat faster and cool slower. Unless the fans run steady or not at all, you should be okay. Turning on the A/C will turn them on quicker and longer because it makes the engine work a lot harder. Hope this helps.
YEP IF SPARK PLUGS WAS OUT OF ENGINE LETTING WATER INSIDE THE ENGINE CAUSING HYDRASTATIC LOCK UP.THAT WILL KEEP ENGINE FROM CRANKING.TAKE A 1/2 RATCHETWRENCH OR BREAKER BAR AND SOCKET.TRY TO TURN ENGINE.IF ENGINE DOES TURN.THEN CHECK BATTERY CABLE FOR TIGHTNESS FREE FROM CORROSSION. CHECK BATTERY VOLTAGE SHOULD BE 12.5 VOLTS.IF NOT BATTERY DEAD NEED CHARGING CHECKED REPLACED.IF BATTERY GOOD.CHECK STARTER FUSE AND RELAY.IF ALL IS GOOD STARTER SOLENOID FAULTY OR STARTER FAULTY.HAVE THEM CHECKED OUT.DUE TO LOCK OUT FEATURE TURN OFF RADIO FIRST BEFORE REMOVING NEGATIVE BATTERY CABLE OR YOUR RADIO WONT PLAY.YOU HAVE TO GET IT REPROGRAMMED.
Turn the key from off to on 5 times and the van will display the P codes on the odometer display. Google those codes and you should find the cause of you problem or an indication of where to start anyway. Some codes don't go away until you unplug the battery.
