2.5 TFSI five-cylinder: oil collects in the air filter housing from the crankcase breather

expensive

The crankcase breather of the five-cylinder 2.5 TFSI leads the oil vapour into the intake, and the stub of the diverter valve sits directly next to it. When the diverter valve opens on lifting off, it carries the oil vapour along, and the vapour condenses in the air filter housing, because the stub is right in front of the housing. The oil therefore collects on the filter element and in the bottom of the housing, the amount grows with use, and under load oil mist comes out of the intake pipe as well. The consequence is twofold: measurable oil consumption, and oil reaching the intake speeds up the carbon build-up on the intake valves, which is already heavy here because of the direct injection. This is not a broken part but where the line runs, so it shows up around 40,000 km already, and earlier on a car used hard. The repair is rerouting the breather or fitting a catch can, 200 to 600 euro.

above 40,000 km200–600 EUR

What to check

  • Take the air filter housing lid off and look at the filter element and the bottom of the housing
  • Wipe the inside of the intake pipe with a finger: an oily film belongs here
  • Ask whether a catch can has been fitted or the breather has been rerouted

MIB3 infotainment: freezing, restarting, black screen

comfort

On the MQB evo generation the MIB3 touchscreen freezes, restarts on its own, and sometimes stays black. In the What Car? survey, 59 per cent of 8Y A3 owners reported a fault, and 44 per cent of those concerned the infotainment. Volume and temperature are set on touch sliders instead of physical buttons, and if the system hangs you cannot adjust them while driving either.

Show the rest

The maker released several software updates. Many cases are resolved by them, but not all. The update is free and fault finding is not, so before you buy, check whether the latest version has been installed.

What to check

  • Switch the system on and let it run for at least 10 to 15 minutes during the test drive
  • Try everything: navigation, Bluetooth, phone mirroring, reversing camera, radio
  • Set the volume and the climate with the slider: does it hang, is the response delayed

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
