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

B9 platform: MMI (black screen, spontaneous restart)

comfort

On the infotainment of the B9 platform (A4 B9, A5 F5, Q5 FY) the most common complaint is a black screen, a unit that restarts on its own, and a boot that stops partway. A significant part of these are software in origin, not a hardware fault: an update installed at a franchised dealer resolves it.

Show the rest

The buttons of the control interface form a separate branch: a control panel damaged by water ingress or a spilled drink does not respond, and that is a parts replacement. On early cars small electrical faults are common too: intermittent dropouts of the central locking, the parking sensors and the phone connection.

What to check

  • After switching the ignition on, wait for the full boot: a screen that stops or stays black is a clear sign
  • Press every button on the central control panel and turn the rotary knob: all of them must respond
  • Try the reversing camera, the audio system and phone pairing too

cheap repair1

TSI ignition coil: misfire, jerking, engine warning light

cheap repair

The per cylinder ignition coil of these direct injection, turbocharged petrol engines fails. According to the Haynes service material this and similar simple electrical faults account for roughly eighty per cent of workshop visits.

Show the rest

In cold, damp weather, on startup, the engine runs unevenly, misfires under acceleration, and the engine warning light flashes or stays on. Do not keep driving with the light flashing: the unburnt fuel destroys the catalytic converter.

What to check

  • Start with a cold engine and watch the first half minute: a rough idle or shaking is suspect
  • On the test drive load the engine at low revs with a lot of throttle: the misfire shows then
  • A flashing engine warning light calls for stopping immediately

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.
