2010 Volkswagen Routan. Why does my front a/c blower sometimes work for one or two hour and stop if I turn the car off for 15/20 minutes and go back to work?

not told heating or cooling mode?? or defrost mode (both hot and with AC dehumidifying mode) no country told or tell what is the weather now , is it hot outside or cold. outside car.??? rain, dry, hot, snow or what> we can't guess this. does heat only fail or drop out?> does the blower motor (actually die or go silent) >? does blower always work on high speed? not told HVAC mode,so answer are impossible or crazy too long. AC cooling modes can do that, if the evap core ICE's up. if R134 refr. is low the evap can ICE up, and and the AC brain detects that and shuts down, until ICE turns to water and drains to the ground under car . THE PCM can also disable AC cool mode for many reasons. here are just some engine EFI PCM shows in distress, lots of DTC errors Engine discovered is overheated, engine shows overloaded. (lots of ways) on climate control versions of HVAC it stops heating and cooling as this control dial is set to say 75F and that temp is reached. manual controls have no such dial.

If you replace a neutral safety switch on a 1998 Cabrio Volkswagen 2.0 l engine and it still does the same thing what is the next step

VIN ? (USA car?) what is the problem ("still does the same thing", does WHAT? (wrong or good or both) did you add wireless remote starter on this car, did it fail before or after the ADD. THE real KEY SWITCH FAILS TO CRANK THE ENGINE. IS THE STARTER MOTORS DEAD AND SILENT? FIRE to Solenoids?, gets 12vdc power not fire, a voltmeter measures all this if you use one., there is no FIRE there ,it's voltage (power) surely no 98 car came with factory remote start, (SM says NO) so there is a story to tell but not told nor full symptoms told , using a normal key or this wireless secret device./< none told. worse yet cars with IMMO, the manual tell us flat out, not compatible with remote starts (none-OEM)\ there are no 2 aftermarket (non-OEM) remote start kits the same. for sure safeties.. IMMO rules VW VW is 1999 or earlier and sold in North America, it shouldn't have an immobilizer. but If your car has the yellow car/key symbol on the instrument cluster (shown activated below) it has an immobilizer. as you can see a 1998 car is just blow,1999 start year some cars made after July 1st,1998 have 1999 opitions. so nobody guess what is there in your car , factory options Most IMMO cars do not allow lacks the car starting and running systems. (it THINKS you are hacking it) see? read here carefully about IMMO. https://www.myturbodiesel.com/d2/1000q/multi/immobilizer-VW-Audi-FAQ.htm note: from there, (immo on this car is very odd) Cabrio and Eurovans have no immobilizer warning light and the immobilizer module is separate from the instrument cluster. that means no cute carbody+key lamp is there in the cluster. for easy immo discovery. outside USA IMMO happened sooner and not told you ,your country. a good aftermarket IMMO maker If this is the topic, NOT TOLD may have LED status lamps to tell what input is failing this is key(no pun) to the solution, failed. and a manual for the IMMO telling how to troubleshoot. a voltmeter is always used, if savvy tech, a $15 tool. the IMMO can block cranking and spark then fuel. immobilized. so can remote starts, OEM remote starts block cranking for a huge list of things, even doors not closed/locked, tranny in gear, or PCM errors. or TCM errors. and more, remote starts are dangerous.

Hi guys, please assist me on this my 2008 Tena Citi Golf has got a problem. The rev counter is moving up and down and is not idling smoothly. I have changed the oxygen sensor, map sensor, thermostat.

Question edited for clarity. Question moved from Land Phones Category. The things you changed have no bearing on the symptoms and clues. Clean Throttle Body and MAF (mass air flow sensor), as opposed to Manifold Absolute Pressure sensor.

2015 Volkswagen Passat 1.8 TSI dying or limp mode

P228C, it has applied exclusively to diesel powered vehicles. It has also meant that the powertrain control module (PCM) had detected a low voltage signal from the control circuit of the electronic fuel pressure regulator, which reflected insufficient fuel pressure.

How do I gt to the 3 glow plugs in my

They are absolutely pulling your leg if they're telling you that you have 7 glow plugs. It sounds like they don't have a clue about TDI's.
Everything you ever wanted or needed to know about TDI's can be found at www.tdiclub.com You should even be able to find a knowledgeable guy in your area that would be willing to take a look at your car. These guys know their stuff. Better than any VW dealer on the planet.
Read this thread - you might be able to figure something out on your own: http://forums.tdiclub.com/showthread.php?p=749854

Are you having problems with your heating/cooling? OR did you get a check engine light and found out about P0380 when you brought it to the shop?
You more than likely have an issue with your glow plug harness. The connectors on the glow plug harness (where they plug into your glow plugs) prob need to be cleaned. Read this thread too:

2013 Beetle convertible door locks click briefly when reaching 10mph. This happens every time the car slows down and then increases speed over 10mph again.

Got it!!! The doors may be locked but the car doesn't think so! The culprit... the gas door lock is sticking!! WD-40 the lock on the gas door and problem solved. Also got a new battery so it could be a voltage surge from a battery going bad.

My polo classic 1.6 is switching off while running. What the cause be. I cleaned the injectors, replaced the coil and the fuel pump.

no year told nor country how sad is that, going Generic, made 1975 to NOW, must we guess cars? and vast evolution ? but Polo not sold in USA (huge hint there) I presume it burns petrol both fuels had 1.6L diesel too TDI yes spark coil is clue, only Coil told. guess #1 engine stalls. PETROL stop guessing or go broke fast, there a can be 50 causes will; you guess 50times, can I watch?(evil face joking) ouch took a bath in fuel on a guess wow. that is brave. not told at all:(and key to not going broke) told the story and evidence ENDED at the STALL> ! 1; fails only hot or cold engine or both 2: using right foot (pumped) can not save the he stall. 3: did it restart fast after the stall . 4: was engine overheating? 5: did any other things 12vdc electrics things vast on car fail at stall>? 6: alternator tests pass? 13 to 15vdc at idle. 7: no loose fuses? 8: at stall and parked, safely , is spark dead? a test all techs do. yes /no , did you know all EFI engine on earth cut fuel instantly if spark is detected bad by the PCM (no simple misfire P030x) 9: scan the PCM at or just after the stall? oops. never skip scans. 10 at restart did CEL/SES/MIL cluster lamp glow running? can it be made to fail parked, in your drive way? or garage if yes, causes are 10x more easy and safe, than while driving but I own a logging scan tool so can drive and log all DTCs live or stored, and makes work 10x more easy. and some errors take 3 hits top store, so we have a pending key on the scanner to find those too. that is it for now we can peel the onion as deep as you like. using tools and basic skills. if will not restart say so and say it cranks fast and do Add, 5%throttle crank to check for IAC dead. or do add WOT 100% throttle to clear floods (petrol crazy rich) never mess with fuel parts, if spark is bad on any cylinder or that invites adding bad parts to the car, now has 2 or 3 things bad. no fun there, and huge down times guessing wrong. it is super easy to buy the wrong parts guessing. zero fun there. stop throwing parts. please. and no the PCM is not bad. no ,no and no.

Oil in spark plugs of1.6 vw polo trendline 2009 model
