What you might want to do to locate actual leak, is have cooling system pressure tested. Any good shop or even some auto parts stores offer to do it for free. That way you're not replacing parts blindly. When they pressure test system you'll find leak instantly.

How to change a wiper motor & repair wiper mechanism on 2005 Audi A4

First time you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows:
1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!!
2. Disassemble the plastic covers from the bottom of the windscreen.
3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables.
4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi.
5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters.
6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation!
7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

The best battery for 2005 Audi A4 is VARTA AGM Ultra Dynamic E39 (with gel technology).

you may have a blown fuse, check all of the fuses for burn marks.

When it leaks, your having major overheating issues with the vehicle, when it fails the bearing or at a major interval like 250,000 km as a preventative maintenance measure

This can be a very big problem. When the car gets louder it is lack of oil in your lifters and that is why the light is coming on. This may be a leak a bad oil pump or a bad pick up screen in the oil pan.

I would pull the oil pan to check for debris and any build up / Sluge in the pan. Also pull and change or clean the screen. Be sure to replace the O ring on the pick up tube. Do not continue to drive your car or you may end up buying another engine. As always you can take it somewhere else for a second opinion.

generally indicates an electrical fault in the powertrain system. Id get it scanned to see if there are any fault codes ASAP. hope this helps.

it should take reg... unlead gas

Under the car:
You will be able to open the hood if you pull off your splash guard and use a long long flat head screwdriver or something like that. You'll see the hood latch in front of the radiator with the cable attached to it at the top near the hood, put it on the drivers side edge of the bottom of the latch and pry to the passenger side, the lever moves from the drivers side to the passengers side, the cable basically pulls the top of it to achieve this. so your doing the same thing on the bottom with the screwdriver.



Release the latch from underneath by the lever that you have to pry towards the passenger side. Then open the hood, and replace the safety release mechanism broken cable.

Join the club ! There is, I believe a group seeking a law suit against Audi for many of these problems.

The reason the automatic fails is often the solenoid assembly that lives inside the transmission oil pan breaks down....if a drivability code sets, the transmission will stay in 3rd gear.

On the 5 speed, this is often the dual mass flywheel coming apart.

Use a dry cell 12V 75Ah 420A

Check the coil(s) and wires first
