EA888 (1.8 / 2.0 TSI): water pump and thermostat housing leak

expensive

The combined housing of the water pump and the thermostat is plastic, and it is bolted directly to the hot engine block. The many heat and cool cycles warp it, it becomes brittle, and then it develops a hairline crack: the fault is almost always the housing, not the pump itself. The signs are slowly disappearing coolant with no visible puddle, the coolant level light, a sweet smell from the engine bay, and later a pink stain under the car. The repair means replacing the pump and the housing together, and the intake manifold has to come off for it: 4 to 6 hours of work. It shows up on model years 2015 to 2025.

What to check

  • Check the level in the expansion tank, and ask whether it needs topping up
  • With a cold engine, smell the engine bay: a sweet smell means a coolant leak
  • Shine a light under the intake manifold, on the right side of the engine: dried or pinkish deposits

EA888 gen3: crankcase ventilation, oil in the intake

expensive

The crankcase ventilation (PCV) of the third generation 1.8/2.0 TSI fails less often than its predecessors, but it is not faultless. After sustained full load acceleration, under hard braking, the return branch of the ventilation can be overloaded, and the oil ends up in the intake instead of draining. The symptoms are oil consumption, blue smoke after load, and deposits in the intake.

Show the rest

This also reinforces the other, already known phenomenon: because of the direct injection, the coke building up on the intake valves grows faster with oil reaching the intake.

What to check

  • After a test drive under load, look at the exhaust: it should not smoke blue under hard braking after sustained acceleration
  • Ask about topping up between two oil changes: adding oil every 1,000 to 1,500 km is not normal
  • Look at the intake connections and the ventilation hose: oily deposits mean oil in the intake

Magnetic Ride: leaking adaptive damper

expensive

Magnetic Ride is an adaptive damper you order separately, the damper uses a magnetic fluid, which is what lets it go firmer or softer, and if it leaks the system reports a fault. Even one damper costs more than 1,000 euros, and they are usually replaced per axle, so as a pair. First check whether the car has it at all, because it was an option and a listing rarely says, and if it does, ask whether any have already been replaced.

What to check

  • Ask first whether the car has Magnetic Ride: it was an option
  • Switch between the driving modes and feel whether the ride actually changes
  • Shine a light on the dampers: an oily streak on the body means a leak

1.8 and 2.0 TSI (EA888): the crankcase breather membrane tears and lets false air in

cheap repair

The crankcase breather carries the vapour that forms inside the engine back to the intake, and a rubber membrane regulates the pressure. Oil and heat harden this membrane until it tears, and from then on the intake draws air through the hole in it. The engine control unit does not measure that air, so the mixture goes wrong: the engine shakes at idle, stumbles when accelerating, and the fault memory gets P2279 for an intake system leak. In the other direction oil starts towards the intake, which leaves an oily film in the intercooler and on the intake pipe and speeds up the carbon build-up on the intake valves. The audible sign is a whistling or hissing noise from the engine bay, loudest at idle. The tear is reported between 60,000 and 90,000 km. On the first and second generation the breather is a separately replaceable valve (factory number 06H 103 495 AK) and costs between 80 and 400 euro; from the third generation it is built into the cam cover, so there the cover is replaced. The maker issued three versions up to 2016, and fitting the pressure variant that does not belong to the engine brings the same symptom back.

between 60,000 and 90,000 km80–400 EUR

What to check

  • At idle listen for a whistling or hissing noise from the engine bay
  • Read the fault memory and look for the P2279 code for an intake system leak
  • Take the air filter housing lid off and see whether there is an oily film on the filter and in the housing

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
