Volvo S60 Exhaust System: The Part That Announces Its Own Problems

Volvo S60 Exhaust System: What It Does

A Genuinely Useful Piece of Context Worth Knowing About Catalytic Converter Cracks — Volvo S60 Exhaust System
If a catalytic converter has developed a crack, this is genuinely worth knowing: documented cases on related Volvo models trace this to low-quality factory welding, with owners successfully repairing the crack by welding it themselves rather than paying for full replacement.
It's also worth knowing that stopping the engine partway through a DPF regeneration cycle can let diesel fuel dilute the engine oil, worth bearing in mind if your driving is mostly short journeys.
