V70 1999 T5 AUTO - black smoke from exhaust

[Joe H]

Good to hear, but what about the oil pressure or are you thinking that is down to a blocked PCV?

Firstly, thanks for all your thoughts and suggestions on what might be causing the issue. This is a great forum.

Diagnostics check showed no signal from O2 sensors.

They found that the O2 sensor wiring was broken. Wiring now fixed. They also found that the plug on the loom side was very brittle. A couple of small tie straps currently holding it in place.

Car now back to it's normal brilliant self.

Other jobs now planned:Given that I've no history when/if the PVC has been replaced, I've decided to get this job done next week.

Thanks once again, regards Paul

Glad it's sorted Paul.

Not sure Joe, not losing any oil, can't see any leaks, but I don't want to take any chances seeing I don't know when it was last replaced if at all! I think replacing it will give me piece of mind.
