4 known faults with sources

Cracked EGR coolerCooling / EGR

Engine / equipment: 1.6 and 2.0 TDI (EA189 and EA288)
Period mentioned: Approx. 2010–2020
Symptoms: Coolant level drops with no visible leak, white smoke with a sweet smell, rising temperature or engine light. In severe cases the engine hydrolocks.
Possible cause described: The internal tubes of the EGR cooler crack and coolant enters the intake. It worsened after the post-Dieselgate software update, which increased EGR use.
Check for the garage: Cooling system pressure test and check for coolant in the intake or manifold.
Cost cited in the source: €400–1,300A rough figure from the original database, not an up-to-date quote.

Applies if: Only if fitted with the 6-speed DQ250 DSG. Confirm the gearbox type.

DQ250 DSG mechatronic and oilDSG gearbox

Engine / equipment: DQ250 6-speed wet-clutch DSG (2.0 TDI, 2.0 TSI and other powerful engines in the Golf, Passat, Tiguan, A3, TT, Octavia, Superb, Leon…)
Period mentioned: 2003–2020
Symptoms: Jerking or shudder when pulling away and at low speed, harsh shifts, gearbox warning or limp mode; codes P17BF, P189C, P0841, P0871 or P0717.
Possible cause described: In most cases the cause is the mechatronic unit (the electro-hydraulic control unit), not the clutches. The oil shares a circuit with the clutches and degrades, carrying debris that damages the valves; the pan can also rust and leak. Volkswagen specifies an oil and filter change every 60,000 km.
Check for the garage: Read codes with ODIS or VCDS, check the oil change history, inspect the pan for rust or leaks and the clutch adaptation values. Replacing the mechatronic control board is often enough.
Cost cited in the source: Oil and filter change: maintenance every 60,000 km; control board or mechatronic: expensive repairA rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: from 60,000 km. This is not a maintenance interval and does not predict a failure.

Applies if: Only if fitted with the air conditioning system described.

A/C not cooling: N280 valveClimate control

Engine / equipment: Air conditioning with clutchless compressor and N280 regulating valve (combustion VW, Audi, Seat, Cupra and Skoda from 2006)
Period mentioned: 2006–2026
Symptoms: The air does not cool or cools intermittently (for example only at motorway speed), and sometimes the compressor rattles with the A/C on. Codes 01232 (N280 valve), P2612 or 00898.
Possible cause described: The compressor regulates its output with the N280 solenoid valve, its most common failure point. Audi issued technical bulletins over a manufacturing fault in this valve on Sanden compressors. Its connector can also become brittle and corrode (especially without the engine undertray), or the wiring fails.
Check for the garage: Read the codes and N280 control current with VCDS or ODIS, measure its resistance (about 10 ohms) and check the connector and wiring before replacing parts. If the valve or compressor is replaced, the whole circuit must be flushed.
Cost cited in the source: N280 valve: a cheap part (about 30 dollars) where sold separately; new compressor with circuit flush: considerably moreA rough figure from the original database, not an up-to-date quote.

Applies if: Transverse EA288 engines with the water-cooled intercooler inside the intake manifold (the garage confirms it).

Cracked water-cooled intercooler on the 1.6 and 2.0 TDI EA288: coolant loss with no external leakCooling

Engine / equipment: 1.6 and 2.0 TDI EA288 with the intercooler inside the intake manifold, liquid-cooled
Period mentioned: All EA288 years
Symptoms: The coolant level drops and needs frequent topping up, but there is no visible stain or drip outside; there may be some white smoke. A clue: a greasy oil-and-water paste on the block next to cylinder 4, near the bulkhead.
Possible cause described: On these engines the intercooler sits inside the intake manifold and is cooled by the engine's own coolant. According to Schaeffler (REPXPERT), repeated heating and cooling can open fine cracks in its inner mesh: the coolant does not leak outside but passes in small amounts into the cylinders and burns, which is why the fault goes unnoticed.
Check for the garage: The garage can check it before removing the manifold: take out the intake air temperature sensor, insert an endoscope camera through its hole, pressurise the cooling circuit and look at the intercooler's inner fins. Have them also rule out the EGR cooler and the head gasket, which give similar symptoms.
