Some weird issues with the Audi 80 b4, and how to fix it
Let me start off by saying the following; I love cars. I know just about every model of just about every brand, and I can recognise almost any car in an instant, just like many of the people reading this probably can. However, I'm not the biggest fan of working on cars. More than changing a light bulb or getting the car nice and clean, I don't do much under the hood. This is important to know for home-mechanics, because many of the things I'm writing here may seem incredibly logical to you, even though they weren't for me.
No matter how reliable everybody might tell you they are, mine was not. In this article I'll describe just a few of the problems I've had with mine, so that you can get ahead of them. Now don't get me wrong, the Audi 80 B4 is an awesome car. It looks great, mine had lots of torque so it was a gas engine that drove like a diesel, and it was comfortable. If you're looking to get one, just keep the following things in mind, and think about whether you can fix the issues yourself or not before buying one.
The first issue; a mind of it's own
Have you ever been stopped at a red light, and felt an extremely high level of poserness from the guy standing next to you revving his car? Well I've been on the other side of that spectrum, however I wasn't the showoff, my car was. It would just rev out of nowhere, sometimes multiple times, sometimes it would even accelerate a little when I was driving, without me even touching the gas. If you ever have this problem, well you have nothing to worry about. It's just something you might wanna fix as soon as possible because you really do look like an overcompensating virgin sitting in your revving car. And yes, you could tell people it's your car and you can't help it, but that's like telling your girl "this never happens" when you can't get it up. It's not gonna help your case, and it'll probably just make it worse.
Open the hood, it should look similar to the image below. Next to your engine you will find 2 sensors, a blue one on the right, and a grey one on the left. They are there to check your cooling water temperature. If your Audi 80 is in poser mode, this is likely the reason why. The sensors are quite fragile, and so if it gets too hot once it may break. I replaced them with original Audi sensors for about EUR 70, but you can get a decent quality one for much less, I've found one on Amazon for 17.44 this is an affiliate link, so if you would like to help me out it'd be great if you purchased it through here, but if not, you can just look up the part numbers. Get the blue sensor here, and the grey sensor here. Remember when taking the old sensors out to let your car sit for a little while beforehand, so that the coolant isn't as hot anymore. Also remember there is a rubber seal on the sensors.

The second issue: RUST!
The Audi 80 B4 is know for it's tendency not to rust, because of the coating on the chassis. However this doesn't mean that other parts can't rust! So on a happy morning I was out having breakfast with my girlfriend, and when I wanted to get out of the parking spot all of a sudden the wheels were in different directions, and even better, the car was automatically lowered. What happened? The control arm and drive shaft snapped in half, and so the car had to be towed, and after that I received a juicy 600 euro bill. Now that was a hard pill to swallow.
There isn't really a cheap "fix" however, before you buy an Audi 80, just check the front control arms for rust, if they are quite rusty and you can put new ones in yourself, go right ahead, if you're like me and you're not really mechanically inclined, maybe look for a different one, or ask a friend to help you. It's better to be on the safe side than to have it break right when you need to be in time for that important meeting.
Just snapped right off.
One day I was driving home, and I heard some weird things. The engine had a very subtle but (to me) noticeable puffing sound, and in the back it sounded like something was stuck in the brake pads. So the next day, I decided to go to an empty parking spot, and I thought it would be a good idea to just accelerate a little, and smash the brakes just to make sure that if there was anything stuck in there, it would hopefully shoot out. Immediately when I hit the brakes, black smoke came from the air vents and started to fill the cabin. Of course the first thing I did was turn off the engine and open the hood. To my great displeasure there was a small flame burning on a puddle of oil on what I believe was the exhaust manifold. Of course the first thing I did is run over to the restaurant across the street and ask them for a water, so that if it would get out of hand I could immediately kill the fire. Luckily it went out, but it did slightly change the colour of my underwear.
Again, this isn't something you should fix after it's happened. Just replace the valve cover gasket to avoid the whole situation all together. I can't find it on Amazon, but I'm sure any mechanic can help you find the right one for your engine, or if you're a true car wizard you'll be able to find it on amazon yourself.
Any car can have issues, after all it's just a matter of how well the previous owners took care of it. Another thing I should point out is that these are issues MY Audi 80 had, and it doesn't mean yours will have the same issues. It's just good to know what to look out for besides the engine itself. If you have anything you'd like to add, please do! See you in the comments.
