Problem 1
Volkswagen Caddy: EGR valve and DPF problems on the TDI
What goes wrong
Short trips clog the EGR valve and particulate filter on the TDI engines.
How to check it yourself
Read the codes, the DPF soot load, and the EGR position values.
The usual fix
Clean or replace the EGR valve; regenerate, clean, or replace the DPF.
Signs: Loss of power, Check engine light
Fault codes: P0401, P0402, P2002, P2463
Problem 2
Volkswagen Caddy: Jerky shifts in gears 1-3 from the 7-speed DSG
What goes wrong
Dry-clutch wear and mechatronic faults, typically from about 80,000 km.
How to check it yourself
Read the gearbox module with a VW-capable scan tool for clutch or mechatronic codes.
The usual fix
Software update and clutch adaptation first; then clutch-pack or mechatronic repair.
Signs: Harsh shifting, Transmission slipping
Problem 3
Volkswagen Caddy: Won’t start when warm
What goes wrong
On the 1.6 TDI the main engine relay (often numbered 109) and its contacts fail, and worn injectors make hot starting worse.
How to check it yourself
See whether it only fails when warm. Check the engine relay for burnt contacts and the injector correction values in live data.
The usual fix
Replace the relay and clean its socket; replace injectors if their correction values are out of range.
Signs: Hard starting, No crank
