Rotten exhaust connection after catalysts 2.8 twin-T
 

Hello,
wanted to know, what should be there? Can't tell anymore.
Should I cut the "bolts" off if there's any. They looks odd and too small to hold these exhaust parts together.

I need to take off catalysts to change 2 lambda probes but don't have so long garage pit to take off exhaust as a whole :D

Car = S80 2000 2.8 twin-turbo

Thanks.

Never mind. Cut bolts in halves and get them out after removal.

There goes 190 usd + my labour. Actually my profit.

Hi, I must appreciate that only few people post their problems and post answers themselves when they got solved. Otherwise people come here to just to look for answers of questions they have.

By the way what makes you think to change sensors, what kind of a problem you faced?

Good Luck!

hello,
we pulled trouble codes out of ecu by connecting car to bosch diagnostics.
Got one bad probe and another "probably dying" so both had to be replaced.

Before that, bad acceleration. Think about 150hp power of 270hp total. Thought this could affect idling problems also, but no. Could be throttle body itself. It was already replaced 5-6 years ago with new oem unit.

I looked at throttle opening value with vag-com at engine idle. It's 18%... Isn't it too much?? Bosch diagnostics showed something about 13-14%. Anyway, looks odd to me.
Is there a way to adapt this value to real one?
