Progress!
Took the car out for a long run this afternoon using my new tried and trusted methods to build heat (low gears while cruising, high gears and full throttle when accelerating) and 'bong!'
Parked up and a quick scan shows the following:
164030 Exhaust camshaft, electrical: short circuit to positive
164031 Exhaust camshaft, electrical: short circuit to ground
120408 Boost pressure control: shutdown due to reaction
It's not saying which bank, so I assume that means bank 1.
Which means, a second faulty sensor rather than faulty harness/loom on bank 2. This is good news
Now the question is, with the inlet cam sensor already replaced on bank 2, and now the exhaust sensor seemingly also dead is it:
A) The task of replacing the intake sensor knocked or damaged the exhaust sensor, killing it or
B) It failed at the same time as the intake sensor, but was being masked by the intake sensor so didn't throw a code or
C) It decided to fail out of pure coincidence.
I'll almost certainly never find out, so looks like I'm in for two sensors rather than one. But, that's better than a new harness/loom for bank 2!
Car's going back in tomorrow for the tech to confirm all of the above and make the fix, then fingers' crossed I should be at the end of this one. Let's see...
