Fiat/Opel/Suzuki 1.3 Multijet, CDTI and DDiS: common problems by mileage
Fiat's 1.3 Multijet is a small chain-driven diesel used from 2003 in Fiats, Opels/Vauxhalls, Suzukis, the Ford Ka, Lancias, the Alfa MiTo and the Peugeot Bipper and Citroën Nemo. It is strong for its size, but later versions carry a particulate filter, and on those the oil level is the first thing to check.

Oil level rising (diesel in the oil)
Symptoms
- Oil level above the max mark and smelling of diesel
- "Change oil" warning long before the service is due
- Particulate filter warning and limp mode
- In extreme cases a diesel can run away on its own oil
Fault codes
Why it happens
Particulate filter regenerations inject extra fuel late in the cycle. Short trips interrupt them and the fuel washes down into the sump. The ECU estimates oil degradation and asks for an oil change when it gets too high.
How to confirm it
- Check the oil level cold on level ground and smell the dipstick.
- Read the soot load, regeneration history and the oil degradation value with a scan tool.
- Check what stops regenerations: thermostat, EGR, MAF, exhaust temperature sensors.
The fix
Change the oil with the correct low-ash grade, reset the oil degradation counter with a scan tool, run a forced regeneration and fix whatever stops regenerations. Explain the driving pattern to the owner.
Timing chain stretch
Symptoms
- Chain rattle on a cold start
- Harder starting and less power
- Camshaft/crankshaft synchronisation faults on some engines
- If the chain jumps: no start and valve damage
Fault codes
Usually no generic fault code: go by the symptoms and the tests below.
Why it happens
At high mileage the chain and tensioner wear, faster with diluted oil and long intervals.
How to confirm it
- Listen on a cold start.
- Check camshaft/crankshaft synchronisation in live data where the tool supports it.
- With the cover off, check tensioner position and chain slack against the service information.
The fix
Complete timing chain kit (chain, tensioner, guides, sprockets) and an oil change.
EGR valve clogging
Symptoms
- Loss of power and limp mode
- Rough idle, black smoke
- EGR position or flow fault codes
Fault codes
Why it happens
Soot and oil vapour build up in the electric EGR valve until it sticks, particularly in town use.
How to confirm it
- Compare EGR specified and actual position in live data and run the actuator test.
- Check the measured air mass at idle (low with the valve stuck open).
- Remove and inspect the valve for carbon.
The fix
Clean or replace the EGR valve and run the self-learn with a scan tool.
