My 2005 Audi A4 engine have idling problem when aircon is on


Sounds like the compressor is failing or seized (for the air con). This would put extra pressure on the system. It could be another fault with the air con system like the solenoids not opening up to allow the flow of gas in the system.

Have 2004 audi 2.0 fsi main fan keeps coming on when moving.


because of the shape of the car and temperature within the under bonnet,audi/ vw use the electric fan to maintain a closer tolerance of engine temperature.for maximum economy.so your main fan will come on more often than perhaps an older car that you may have owned.as changing the thermostat has shown no change.

Air bag light started coming on /dash constantly


the likely fault is the cables running to the seatbelt pre-tensioners under the drivers or passengers seat in the front of the car.

This may be simply the plug and socket have become seperated from sliding the seat back to clean, a common fault, or the airbag "clockspring" connection unit in the steering wheel has a broken ribbon cable inside the column housing.

To see if its the airbag clockspring, buy a 4 ohm resistor from maplin or radio shack, disconnect the battery on the car, unplug the airbag in the steering wheel and connect the resistor across the 2 contacts in place of the airbag, reconnect the battery, if the light goes out the clockspring is the fault, if not its the SRS system wiring under the seats.

2002 sequioa sudden stall


Often when the battery is disconnected or replaced the computer will lose it's learned idle settings. You could try letting the engine idle in park until the engine temperature comes up to normal and leave it like that for a few minutes, then put the Air con on and let it idle again for a few minutes, then switch the air con off and put it into drive. If it does not stall, let it idle in drive for 2 minutes or so, and then do the same with the Air con on. This should relearn the base idle settings and stop it from stalling on you. Before you carry out this procedure you should make sure that when you replaced the battery you didn't remove any other plugs or knocked anything that may be causing the fault. If you try this procedure and it still stall when you select drive, you will need to get a Mechanic to check the vehicle over.

Hope this helps,
Mark.

Hi Guys,
I have had this problem several times and first was solved by claring leaves from two drains under battery. Second time I did the pollen filter thing with silicon as hophouse did above, it is looking good so far.
