How to fix electrical problem VW Golf air conditioning?

Dismantle and inspect all the failed components. Cut apart old filter drier and inspect for wear particles. Make sure the filter is 100% effective in stopping all wear particle from circulating through system. If there is any doubt at all, then it is wise to fit an extra filter anywhere in the TX valve supply line. Use the largest filter you can squeeze in the engine bay and make up two new hoses to suit, using bubble crimp tooling.The filter must have a fine Micron rating and does not need to contain any desiccant, because the original filter drier in series has enough inside it. Remove and clean TX vale and flush entire system of wear particles. Drain and measure oil out of new compressor. Add or remove oil quantity, so that it is equal to 20% of system Gas Charge. Evacuate system for minimum of one hour and gas up with pure R134a, which does not contain a leak dye, because we have found this dye to be abrasive and drastically shortens compressor life.

These deduction are based on a period of 20 years, maintaining a fleet of 100 trucks and keeping records of what gives the longest compressor life. One of our Sanden Compressors lasted 14 years and 1.5 million kilometers on an N12 Volvo Tipper working in a dusty environment where the owner had the windows always shut and never turned the AC off. This compressor never wore out, but pulled a small end out of one of its 5 pistons due to metal fatigue.

Hope this tip prolongs your compressor life.

How do you replace the front turn signal bulb located on a 2002 Audi A4?

The complete headlamp unit has to come out. It is held in by about 6 or 7 hex headed screws. You need a long handled tool for this, but they are pretty standard these days. Once these are removed the unit comes forward and allows access to the bulb. Replacement is a reversal of the process.

take out headlight theres 2 hex bolts at the top f the unit which u need to take right out and 2 hex bolts at the back of the unit which are on a slide so only have to be slackend 5 minute job

I have a 2002 A4 Quatro. I removed the two star bolts located at the top of the unit then loosened the other two star bolts located at the back. The headlight assembly does not have to come all the way out in order to replace the turn signal. Pull it out far enough so you can loosen turn signal bulb assembly. I had to remove the plastic covers on top of the engine compartment to get to the two bolts in the back. Snamps right back in though.

Clarification

On my 2002 A4 Quattro, there are two screws on top of the headlight assembly(obvious) and two behind it (not so obvious). And they're #T30 Torx, not hex (allen). All four screws are under the hood. On the passenger side, to get to the two screws behind the light assembly, you must first remove the plastic air duct (3 pieces) that lead from the grill to the air cleaner box; this requires removing two Phillips head screws that attach the forward-most duct piece to the grill. The 3 duct pieces just snap together. When reassembling the duct, I found it easiest to install the front one first.

The 2 things I would add are: 1) there really are only 4 screws to remove. The top two are easy. 2) The other two screws connect the bottom of the headlamp unit to the vehicle. In order to get the bottom 2 out, you'll need a screwdriver about 10 inches long to get leverage for the #T30 Torx. I'm not a mechanic either and I was able to do this in less than 10 minutes once I had what I needed. Cost: bulbs about $4; T30 Hex at Lowes for about $5.

What oil do you use in your Audi A4?
