If spark is good, it could be fuel pump or filter, or even your solenoid. Message me with more info. does it:
1. Try to start? - Fuel issue, or battery issue?
2. Click - Battery issue
3. Nothing? - Solenoid issue

SOURCE: VW Polo doesnt start

when you turn the ignition switch on, the gas pump relay should turn on and go off to pressurize the system. You can keep the car in neutral/park, get down as low as you can to the driver's floor board and reach up and turn the ignition switch to on [but not to the point that you actually allow the engine to turn over]. Repeat this step until you hear the relay and can actually feel the little black (box) that is actually performing an electromechanical switching.

Check here first----> , it is usually on a diagram within or near your fuse panel.

It is a start. Secondly, I'd check for any play/movement on your negative/positive terminals of your battery and starter motor. Should these be snug, loosen them and clean the terminals on your battery AND starter. This may be "stupid" and "obvious" to most but they don't do it and that is usually the main cause... even if it "appears good".

VW CC 2011 AC fuse


Hello Adriana,

Do you have your owners manual? If you do, there should be some info available for the location of the fuse box and a description and ratings of the fuses and relays.

Sometimes the fuse box cover will also provide this information.

The first place to start your trouble shooting is to look for a tell tale dash indicator alert for potential fault codes.

Does your A/C compressor come on when you select A/C?
How do you know you have adequate A/C coolant pressure?
Have you checked for a broken or missing belt? If your vehicle uses
multiple belts instead of a serpentine belt (which drives all of the accessories.)

See the link below for more information.

Vw polo overheats


a cold hose indicates an air lock in the cooling system, if this is the case have it bled to remove the air lock. it could also be combustion gases leaking into your cooling system indicating a possible head gasket failure, your anti freeze can be tested for traces of combustion gases.

A local garage mechanic says the clutch has stopped working on ac that is why it blows hot air instead of cool says it will cost $900. to fix cause I have to buy the whole ac unit does this sound correct?...


have you tried charging the ac system? most ac compressors have a pressure switch that will not allow the relay to engage the clutch if the coolant pressure is low. $15 can of r134a and maybe a $20 Haynes manual is well worth the price difference, eh?

My VW Polo 2001 air bag sign is on all the time. Is the car safe to drive and can I take it to any auto electrician as the vw people are so expensive even for a service


music to my ears,YOU take your car to a VW dealer to get it on the diagnosic machine,THEN you take it to your favourite mech to work on it.the diagnostic computer only gives codes,it dont tell you whats wrong,so get a written report done.i am a fully qualified tech and i get my own done this way,as its cheaper.........(mickey mouse diagnostic computers only give codes NOT itemised faults)

1992 VW Polo 1.3L Coupe: warning light mystery


Bought a very reputable diy service manual for the vehicle, and that plus a bit of thought and nous gave me the cure: no intrinsic problem other than loose relay connections. Went round with the wiring diagrams as guide checking all electrical connections in tight and relays fuses etc all good. Switched on and no problem any more.

By the way, vehicle is 1992 VW Polo - not Fox (which in UK is a variant of the Polo)
