yes

The three types of auto emissions are evaporative emissions, refueling losses, and exhaust emissions. if getting a check engine light have vehicle scanned for trouble code

As far as the engine cover, is this what you wanted?

There’s probably a misfire in the cylinders. Have the computer scanned for error codes. You may need a new mass air flow sensor, oxygen sensors, spark plugs and ignition coils. The smell is most likely burning fuel as the car tries to inject more fuel to compensate for the misfire.

Have you changed the MAP sensor (on the intercooler)?If not, thry to replace it with 3bar sensor, stock is 2.5bar!

I don't know. Look at it and see!!!

yes clean out the drain holes at the bottom of the door normally 3 slots near the edge of the door next get a sheet of clear plastic and using a good sealant adhesive stick the plastic around every opening of the inner panel of the door That stops water splashing out of the holes against the trim and running into the car cost tube of sealer , sheet of plastic and your time

I, feel sorry for you, after reading your problem, but don't worry you visit the Reliable-Store they will help you for sure Polo

Try to leave the car overnight so when it is tested it must be cold. The fault will show uo only when cold. Cold start valve is at fault.

never saw where you had the fault codes read would have been a good place to check first but you can still do it now to save money

When you say shopping you mean Stalling right. If yes then the usual cause is a failing Relay 109 which is the main power relay . The early golf had a grey relay which failed due to dry solder joints etc the modified black relay was issued to elevate the issue. Relay 109 supplies power to these , Glow plug relay - Fuse 32 ECM Fuel quantity adjuster - Fuse 34 Cold start injector Waste gate bypass regulator valve (N75) Change over valve (N239) EGR vacuum regulator valve (N18) Mass air flow sensor (G70) - Fuse 43 Clutch vacuum vent valve (if equipped) Brake vacuum vent valve Relays for preheating coolant (if equipped) Crankcase ventilation heating element The ECM supplies power (and sometime ground as well) for: Fuel cutoff valve Cruise control switch Manifold (intake) air pressure/Intake air temperature sensor Needle lift sensor Engine speed sensor Engine coolant sensor Closed throttle position switch (part of "go" pedal) Kickdown switch (part of "go" pedal) Throttle position switch (part of "go" pedal) Fuel temperature sensor Modulating piston displacement sensor The ECM also communicates to the instrument cluster electronics and transmission control module (on automatics). As a result of this, you can see why if the relay starts to cause power to flicker, or voltage drops, for all of these components, the results can be "unpredicatable" and none of them desireable.

The rear door lock actuator has failed in the door locking unit this is a common problem you can manually unlock the door to replace the latch if you didn't have the deadlocking on if you cant try pressing the locking button twice so when the car is locked the flashing red light is not blinking ie off on the drivers. Doing this usually causes the faulty lock to release the dead locking so you can pull the inside handle to unlock the door.
