If you know what your ac pump looks like, follow the lines till you find a blue capped valve, its on the outlet side of the compressor.

Low compression in two cylenders


A compression test is only a partial diagnostic. You should have a cylinder leak down test done. Low compression could be valves, Rings, head gasket or cracked head or block. IT could also be nothing depending on how low it is. So a cylinder leak down test tells you which one it is. The mechanic hooks a pressure hose to the spark plug hole, air pressure is put in the cylinder when the valves are closed. The location of the leak can then be heard.

Hi, The air con in my 2003 Audi A6 1.9 tdi 130 is blowing warm air the air con rad is fully gassed and all fuses are ok . Thanks in advance for any advice on how to fix


The only other thing then would be if the compressor is turning, engaging, and the cooling fan working properly. You should either be able to see the compressor clutch engage, as the switch is energized, or at least hear it click loudly when the switch is energized. If it is not, then there are sensors for the low pressure/high pressure line to tell the compressor when to function, that also have to be checked.

As the engine runs with the compressor turning, one line should be hot/warm, the othe,r (larger diameter hose) should be cool/cold, if the system is working properly.

If the compressor is turning when you have the A/C turned on, then see if the cooling fan is running as well. It must run to remove the heat and cause the process to function properly.

Good luck!

Can't find where to put the freon in my Audi 96 A6 quattro?

Note:
Only a high pressure service valve is used for A/C system servicing. A low pressure service valve is not installed. Perform all A/C system service (ie. discharging, evacuating and charging) through the high pressure service valve only.

We have a 2007 CX7 and the air conditioning is not working well on either recirc or outside air in low ambient temps. When idling at the lights the air con becomes worse. There is no belt sqeal, and I dont...


When you have a moment pop the bonnet and look for the air con compressor run by a automotive belt on the side of the engine. Get the engine running at idle and then get someone else to turn the air con on whilst you watch the compressor. As the system is turned on the compressor clutch should engage and the unit should start turning, if this isn't happening there isn't enough pressure in the system (leak or just low on pressure) Get to your local air con guy and they will pressure test for leaks. Air con system is run on pressure, so that is really the issue you need to rectify

Note:- Manufacturers put the air con rad infront of the engine rad so stones get to that first, check the condition of the front rad through your bumper

Have an engine code for a check engine light 1423 and 1411 for an Audi A6 Quatro 2001


P1411 - secondary air injection system flow too low Bank 2.
P1423 - secondary air injection system flow too low Bank 1.
Check vacuum hoses to combi valves ,
most common split air injection pump which is riveted with aluminum rivets,ck rivets if they coming out ,pump doesn't build enough pressure.
In this case take pump out and put bolts instead of rivets all around pump case.Repl. all rivets not only broken one.Bolts sold at HomeDepot , just find a needed size.
