If your 2001 Volvo S60 2.4T, S80 T6, or V70 T5 is running rough, it might be a catalytic converter failure. Common symptoms include:
Loss of power
Rotten egg smell
Check engine light (P0420/P0430 codes)
Loud rattling (if the converter is broken inside)
Replacing the catalytic converter isn’t cheap, but sometimes removal is necessary if it’s clogged or damaged. On models like the 2001 Volvo V70 or S60, access can be tight—especially with turbo setups. You’ll need basic tools, patience, and maybe PB Blaster for rusty bolts.
For a DIY replacement, check for OEM or aftermarket options. The V40 and S60 use different setups, so double-check fitment. If you’re not comfortable, a shop can handle it—but expect labor costs.
Pro tip: Fix any underlying issues (bad O2 sensors, misfires) first, or your new cat will fail too!
