1.6 TDI EA288 (CLHA/CRKB/CXXB/DCXA/DGDA/DGTE)
Volkswagen · 1.6L Diesel I4
2012–2021
"MQB-era 1.6 TDI. Robust bottom end and turbo; the pain is the emissions kit. Engines built to September 2014 can overheat when the switchable water pump control slide fails (VW TPI 2041955); EGR cooler, DPF and AdBlue sensors suffer on short trips. A motorway commuter car, not a city car."

Known Issues 5
Switchable water pump control slide failure - overheating (built to Sep 2014)
▸Coolant temperature climbs to 130 C with the red warning lamp, heater behaviour erratic, code P1257 if a non-switchable pump was fitted
The electrically switchable water pump or its control slide (Regelschieber) fails on 1.6 and 2.0 TDI EA288 engines built up to and including September 2014 - VW TPI 2041955 - and can happen at low mileage. Replacement pump with valve 700-1,200 EUR (aggregator estimate, around 100,000 km). Fit only a pump with the solenoid valve.
Greek summer heat leaves no margin - stop immediately at 130 C.
Timing belt - interference engine, 210,000 km interval
▸Preventive only - a snapped belt bends valves
VW interval for the TDI belt is 210,000 km; the belt also drives the high-pressure fuel pump and the water pump sits on it, so replace together. Dealer job 700-1,100 EUR.
Ask for the invoice before buying a 200,000 km car.
AdBlue (SCR) sensor, heater and pump failures
▸AdBlue system warning, no-restart countdown, NOx sensor codes, crystallised deposits around the injector
Euro 6 variants carry SCR; sensors and pumps fail and the system can refuse a restart after the countdown. Aggregator estimate 1,500-2,500 EUR around 120,000 km together with DPF work on short-trip cars.
Do not let the countdown run out - the car will not restart. Use fresh AdBlue; it degrades in summer heat.
DPF clogging and oil dilution on short trips
▸DPF warning, frequent regenerations, oil level above MAX with a diesel smell
Short trips interrupt regeneration; the DPF loads with soot and post-injected fuel washes past the rings into the oil. Shorter oil-change intervals and regular longer drives are the workshop advice.
Check the dipstick: oil above MAX on a city car means diluted oil - change it.
EGR cooler and valve sooting, sticking or leaking
▸Limp mode, power loss, EGR fault codes, unexplained coolant loss when the cooler leaks
The most common workshop finding on EA288: soot and oil mist on the cooler and valve cause sticking and limp mode, and some coolers crack and leak coolant. Check actual EGR flow in the measured-value blocks before deciding between cleaning and replacement; software updates change the EGR maps.
Short-trip Athens use is the trigger; a weekly motorway run keeps it clear.
