April is a month when everyone cleans something. I decided to clean and wash my car. During the process I have made several pictures so i will share them here. It is my Audi A6 with 18" RS8 rims on it. It also has sport springs but i will write about them later. I will also make several pictures and compare them with stock springs.

The most important and interesting thing is to find all information about your car. To find it you can see on a sticker in the spare tire place. There you will see option codes. Every code has a meaning and can tell you a lot about your Audi or any other car. A list has 11622 option codes. I have listed a part of codes here but decided to remove them because a list of some Audi option codes is huge. This website will help you a lot. Audi option codes.

Using VAG-Com software I have found a fault code that says: Engine Coolant temp sensor. I will explain how to change the sensor and what tools you will need.

First, it is very hard to find the location of the sensor. Location is different in every car. In this article I will be talking about 2001 Audi A6 with Tdi engine. I have made a picture to show where to find the sensor.


A code of the water temp sensor was 076919501C. This was a stock Engine coolant temp sensor. Take a look at the image below. It was the same as you can see in the picture.

I have changed it to another Engine coolant temp sensor and the code of the new sensor was 059919501A. A new sensor was a little bit different. Look at the picture. Actually it was the same but the color was green.

It is a green 4 pin temperature sensor. You will also need an O-Ring and a clip. It is not necessary to buy a new clip because you may use an old one. But don't forget to buy an O-Ring. This will be necessary.

You will need a paste which becomes like a rubber after 10-15 minutes. Just spread the paste on the rear of the sensor. I cannot remember what paste I have used but I took a picture of the tube. Can't provide you more information on it. It was written Victor Reinz and Reinzosil on the tube as you can see from the picture.

It is not so easy to gain access to the sensor. And remember that a car must be cold before changing the sensor because when you remove the sensor a coolant will start leaking out of the car. Plug up something to stop leaking and then install a new sensor.

Assembly of CV Joints on drive shaft

- Gearbox Side

1) Place the clamp and boot with its cap on the shaft. If the joint is provided with a Belleville washer, position it correctly on the drive shaft.

2) Match the grooves on the inner race with those on the grooved part of the shaft and push the joint onto the shaft. If necessary, strike carefully on the inner race.

3) Fit the retainer ring in the groove on the drive shaft. Always use a new ring.

4) Fill the joint from the side opposite the boot with about half the grease in the tube supplied.

5) If a protective cap is provided, fit it in place taking care to match the holes with those on the joint.

6) Fill the joint from the boot side with the remaining grease.

7) Fit the boot cap on the joint taking care to match its holes with those on the joint.

8) Close the small clamp so that the boot is securely anchored to drive shaft.




Assembly of CV Joints on drive shaft

- Wheel Side

1) Place the small clamp and the boot on the shaft. If the joint is provided with a Belleville washer and lock washer, push these parts onto the shaft.

2) If the joint has an internal circlip this has to be fitted in the groove on the drive shaft. Always fit a new ring. If the fastening system requires a Seeger ring ring this is supplied already in place on the inner race.

3) According to the Cifam standards, joints are supplied pre-lubricated with the optimum amount of grease. A few types of joints are supplied with a separate container of grease. In this case the joint should be filled with about half the grease in the container.

4) Match the splines on the inner race with those on the grooved part of the shaft. Pay particular attention to the retainer ring. Using a plastic hammer, push the joint on to the shaft slowly until the retainer ring snaps shut. Do not fail to check that the joint is fitted securely on the shaft cannot slide.

5) If the grease has been supplied separately, use the remaining amount to grease the joint completely. Fit the boot on the joint in the correct position and tighten the large clamp with pliers. Make sure the boot is securely anchored to the joint.

6) Insert a screwdriver between the boot and the drive shaft to let the air out of the boot.

7) Tighten the small clamp using pliers and check that the boot is hermetically sealed. Turn the joint a few times around the shaft axis to check that it is correctly installed.



Removal of CV Joints on gearbox side of drive shaft

Wheel side

1) Grip the drive shaft securely in a vise. Remove the clamps Take the boot off the joint by sliding it along the drive shaft.

2) If the circlip is visible, spread it open and slide the joint off the shaft, striking it gently on the front face with a plastic hammer.

3) If the circlip is internal (not visible) the joint has to be removed from from the shaft by striking it on the front face of the inner race.

4) Remove the retainer ring, if any, on the drive shaft. Take the boot off the drive shaft. Clean the drive shaft along the grooved part and check that the teeth are intact.

Gearbox Side

1) Grip the drive shaft securely in a vise. Remove the small clamp. Remove the boot with its cap by sliding it off the drive shaft.

2) Remove any protective cap taking care not to damage it because it will have to be used again for assembly.

3) Position the joint over the jaws of the vise so that the drive shaft is in a vertical position facing downward. Open the circlip using the special pliers.

4) Slide the drive shaft out of the joint by striking the front face of the shaft, with its cap and the Belleville washer, if any. Clean the drive shaft along the grooved part part and check that the teeth are intact.

It has been a long time but today I decided to continue writing my blog about my Audi A6. As I remember I have been trying to choose rims for the A6. About a month ago I bought Audi R8 rims. It fits great on my car. I have chosen 18" rims. Before that I spent lots of time searching for various pictures on Google and on forums. Eventually I found these R8 wheels.

It looks great on Audi R8. Just take a look at it. Of course you can always find a better ones but everything depends on your need and the price.

Well, I also made several pictures to show how it looks on Audi A6.

I have found several great wheels that look great on Audi A6 (C5). These are the wheels that I like most but it is very difficult to choose the best one. I have made several pictures with PhotoShop so you can see the difference. I would like to buy 18" wheels. 19" and 20" wheels are really expensive and maybe too big for Audi A6 but also should look great. Tyres should be 225x40. I think it is the best for 18" wheels. Now I would like to show you pictures I have made and in the near future I will show you my decision.
