997.2 3800 DFI Oxygen Sensors
Discussion
Anyone else had two out of the four go simultaneously?
I was in stop/start traffic for an hour or so on the M25 today but apart from the oil temp understandably creeping over 100C, everything was normal. Oil temp came down to 80C odd once we got going again, but off the motorway I switched off for about a 3 minute pits stop. When I switched on again I got the check engine light and message to visit the workshop. Engine went in to limp home mode, and I got it back to my OPC with no further drama. The diagnostics say two of the O2 sensors have failed... They think its odd that two have gone together and suspect it could be their controller. Will see what happens after it's been in on Thursday...
(Engine has 47k miles. Have used Shell V-Power since July when I bought it.)
