EA211 (1.0 to 1.5 TSI): water pump and thermostat module leak

expensive

In the EA211 the water pump and the thermostat are one plastic module, and the pump is driven not by the timing belt but by a separate toothed belt behind the exhaust camshaft. There are usually two problems with it: the plastic housing warps or cracks (slow coolant loss, a sweet smell, rising temperature), or the drive belt ages (a chirping noise, then an engine left with no cooling). The housing is particularly sensitive if oil reaches it: for example from a leaking crankcase ventilation. The module has to be replaced whole: dismantling it warps it in itself.

What to check

  • Check the level in the expansion tank, and ask whether it needs topping up
  • After a cold start smell the engine bay: a sweet smell means coolant
  • Look for dried, whitish pink deposits on the exhaust side of the cylinder head

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.
