For younger Audi enthusiasts that drive older cars, the 1.8 liter turbocharged engine (1.8T) is well known to say the least. Most young Audi enthusiasts have a 1.8T under their hood, so learning how to fix certain small issues can be extremely helpful for them. Which is why videos such as these from FCP Euro can help.
In this new video, we get to see how to change the coolant temperature sensor on the B6 Audi A4 1.8T.
The reason this video is important is that the coolant sensor on the 1.8T is actually quite tricky to get to and replace if you don’t know what to expect. The part itself isn’t expensive and if you can replace it on your own, you can fix a problem without too much investment. However, you need to know how to do it and this video is rather helpful.
This is especially helpful as older cars often have issues such as these. Most of these engines have well over 100,000 miles, many of them have over 200,000 miles, so sensors and such parts tend to go bad.
The actual replacement of the part isn’t what’s tricky, it’s getting to it, as it actually sits on the back of the engine. If you know Audis, you know that getting to the back of the engine is rather tricky. Due to their far-forward, longitudinal engines, you’d imagine that getting to the back of them would be easy. But the nature of Audi’s Quattro all-wheel drive system and the placement of the firewall, it’s actually tricky to get to the back of the engine.
It’s also not just the B6 Audi A4 but also the B5 A4, Audi TT and, in Europe, Audi A3. Admittedly, the TT and A3 have transverse-mounted engines, so you just have to account for the back of the engine being sideways, so to speak.
So if you have a 1.8T in your Audi and you’re having a coolant issue, it might be the coolant temperature sensor, so check this video out.
