So the World's Fastest Boxster has spat the dummy. A few months back, i had an exhaust leak at the junction of back box and elbow. It threw up a P2096 and P2098 Ageing O2 sensor. Given if changed the left bank post cat 02 sensor a couple of years earlier, this seemed like a red herring. Unique cleared the codes and then it was cool for a few months, right untili i was about to head off on my road trip in the Dark Knight.
When Mrs P collected me from the airport, she said tge CEL started blinking on tge way there and it wasn't running nicely.
It's been parked up since, so yesterday i had the time to pull the rear bar off and sort the exhaust leak. That all went swimmingly, but using my OBD scanner it threw up the following codes. Whats the consensus, that if i change the post cat O2 sensor on the right bank that it should sort the rest out?
TIA

Cam position sensor. Can't see a variocam solenoid popping up ignition timing issues. May be wrong though......I'm not always right

I did write a small ode to a fallen friend in the post below.

R.I.P Worlds Fastest Boxster

If we can all take a moment to share in the passing of an old friend, a true sports car and gave us almost 4 years of smiles. What was expected to be a solenoid issue appears to be a chain tensioner issue. The effort to remove the engine and then strip it to confirm, is uneconomical. It was a...

In the new year, I'll have time to figure out as to what will replace it. 981 and TTRS are the current front runners for Mrs P's new daily. The quattro actually makes more sense for her during winter drives to and from work
We shall see.
