Common Problems & Weak Points

Issue	Typical Mileage	Repair Cost (Est.)	Severity
Turbo Housing Crack (IHI)	~80,000 km	€400 – €800	Low

Turbo Housing Crack (IHI)

The IHI VL36/38 turbos used on standard T-Jet engines can develop cracks in the exhaust housing near the wastegate. This leads to loss of boost pressure. Garrett turbos on higher power models are generally more robust.

Typical Mileage: 80,000 km

Cost: €400–800

Buyer's Inspection Checklist

Check for boost leaks/hissing sounds.
Inspect turbo area for cracks if high mileage.
Verify timing belt history (change every 5 years/120k km).
Ensure spark plugs are changed on time (sensitive to old plugs).
