Take some time to clean and polish the throttle body bore with 800 grit and WD40 so the butterfly doesn't stick shut.

Yeah I was cleaning it out. Just took more removing of parts than I expected. Carb cleaner seemed to do the job just fine. I don't think anyone has been here since it left the factory.

No it won't. The throttle body is alloy, the butterfly is brass or steel. It wears a ridge into the alloy and can stick. So it needs a clean up with very fine emery to remove or at least smooth out the ridge. This is why the throttle bodies stick. There is no cable to force it open either.

There was no noticeable ridge inside the throttle body, so it's probably alright? Also it doesn't naturally stay sprung in the fully shut position. Possibly to prevent that problem happening?

I really need to be careful of brittle plastics. Like this covering the coil pack wiring. This is what makes me think I'm the first person here for a while.

The central locking issue appears to be that you need many presses to unlock the rear. I think it should be two presses but for some reason it took around six unlock presses before it started working properly. Now unlocks fine on two presses. Go figure.

This was found out after I had stripped the inside of the boot to get to the emergency release handle for the petrol cap.

Sat nav screen is completely blank. I think it's unfortunately buggered from someone disconnecting a battery and not leaving time for it to shut down. Probably corrupted the flash. Looks a right faff to reprogram - not least from the lack of JTAG port on the board.

Second hand units range from £25 to £70. £25 is the wrong model number, £70 is the same model number. Expensive almost certainly work, cheap 50:50 if it will talk together. I'll leave it for now as it has a few things on the more urgent list to be sorted. Just the blank sat nav screen is quite annoying.

Finally this is the emissions print out. Wasn't too tragic. High HC is probably from old fuel making it run rich, been sat around for a while and/or not being upto temperature when the test was initially done.
