Checked and updated 27 September 2026
Problem 1
Coolant loss leading to head gasket failure on the 1.6 D2
What goes wrong
The 1.6 D2 has a cooling-system weakness: it starts with intermittent low-coolant warnings and can end in head gasket failure or cracks. A coolant hose can also rub through against nearby parts.
How to check it yourself
Log how often you top up coolant. Inspect the hoses for chafing and have a pressure test and combustion-gas test done.
The usual fix
Replace chafed hoses and secure them. Don’t keep driving with a falling coolant level: a garage should confirm or rule out the head gasket before it overheats.
Signs: Coolant loss, Engine overheating, White smoke
Fault codes: P0217
Problem 2
Dual-clutch automatic judder, overheating warnings, or failure
What goes wrong
The PowerShift dual-clutch gearbox (shared with Ford) suffers from clutch and control-unit problems, especially with the 1.6 diesel and 2.0T petrol.
How to check it yourself
Read the transmission codes, note judder when pulling away, and ask a Volvo dealer about software updates.
The usual fix
Software update and clutch adaptation; worn or contaminated clutches and failed control units are replaced.
Signs: Harsh shifting, Transmission slipping
Problem 3
EGR valve or DPF problems on the diesels
What goes wrong
Soot clogs the EGR valve and particulate filter, typically between 80,000 and 120,000 km.
How to check it yourself
Read codes and live data for EGR position and DPF soot load.
The usual fix
Clean or replace the EGR valve; regenerate or clean the DPF.
Signs: Loss of power, Rough idle, Check engine light
Fault codes: P0401, P0402, P2002, P2463
Problem 4
Diesel smell from a cracked fuel filter housing
What goes wrong
The fuel filter housing can crack around the inlet connection and leak diesel.
How to check it yourself
Look for wet diesel around the fuel filter housing in the engine bay.
The usual fix
Replace the fuel filter housing. A fuel leak near hot parts is a fire risk: don’t drive until fixed.
Signs: Fuel smell
