Audi a4 1996 2.8 Quatro - Freon Low pressure input- where it is :)
Hi, I saw that you already helped someone with the same issue and you ware referring to some chart where you indicated the exact location of the low pressure input so that I can load some freon in my car. Please if you can include this chart to email@example.com Thank you so much. Peter
Re: Audi a4 1996 2.8 Quatro - Freon Low pressure input-...
To get all of you BIG mechanics STRAIGHT.....after wasting my time following your suggestions here is waht I found when I finally brought the cat to Audi Dealer. Audi 1996 A4 Quatro 2.8 Does NOT have low pressure input OK.So the only way to fill in the AC is by going to the dealer - $150. Now if you AC still does not work try checking your AC-Relay (the dealer will try selling it to you for $132 plus +$150 labour) you can buy the relay for $19 and put it yourself for 5 min. All relays are below the dash on driver's side. 4 bolts to unscrew and you are there. Good luck everyone that happened to have the same issue.

I have a 96 cabriolet, and the AC controls are cable operated. Check your cables under the dash. there i a button for the ac, right next to the recirculate button separate from the dials. If that doesn't kick in your AC, check relays and fuses, and then low pressure switch, assuming you already know that you are full of freon.
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.
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.
There are two adjustment points (screws). For example left headlight: you will see one point near the end of left wing, at bottom side through a wing hole. This is for vertical plane headlight beam adjustment (up-down). Another one point is against water radiator side. This is for horizontal plane headlight beam adjustment (left-right).
KEEP BACK FROM DEALERSHIPS!!!!! WILL RIP YOU OFF BIG TIME.....ALWAYS GET A LOCAL GARAGE TO DO THE WORK(ALWAYS ALOT CHEAPER AND BETTER) SHOULD HAVE GOT A ROUGH PRICE FROM YOUR LOCAL GARAGE FRIST........
The best balance of price, quality, availability that I have found is Mobil1 synthetic - it's on Audi's approved oils list. With the 2.0T engine, you absolutely want to use synthetic (the Audi turbo fours are known for oil sludge issues), and you want to do a SeaFoam treatment every 15k miles or so - that combination will keep your engine in great running shape.
