comment Is it possible (or practical) to repair a turn signal cancel switch instead of replacing it?
The one reason that a used part might not be such a good idea is that on some cars, it's essentially the same part in the turn signal switch mechanism that breaks. So you might just end up replacing it with another one that'd break fairly soon if you buy used.

comment Check Engine code P0420 Catalyst efficiency below threshold bank 1
Narrowband O2 sensors (which is what you have) switch between rich and lean indications exactly as your graph shows, so they are at least partially working... You'll need to find out which sensor is which but if S12 is the secondary sensor, this graph looks a little weird to me (assuming it uses the high voltage as a 'rich' indicator, which is what I'm used to seeing) as the second sensor seems to be staying 'rich' a little longer than I'd expect. Nevertheless it's hard to tell from the graph if it's the cat or sensor. I'd get the sensor checked out first, though...

comment Can I replace a compliance (Lower Control Arm) bushing myself?
Depending on where you are, that doesn't seem to be out of question - I'd guess they're budgeting about 3 hours work which seems fairly reasonable for both bushings. Out here the independents are charging around $100/hour so I wouldn't be surprised if the main dealers are charging between 120-150 or more.

comment No check valve on valve cover
Did you clean out the piping between the breather and the airbox? Also, do you see oil fumes if you remove the oil filler cap when the engine is running?

comment Hard shuttering and engine dies when A/C is on at idle
I'd research if it's supposed to raise the idle - most cars I'm aware of do as the a/c compressor can add a lot of drag on the engine.

comment Can I replace a compliance (Lower Control Arm) bushing myself?
You'll have to have something to press in the new bush with (like a socket that's a very good match size-wise, or a piece of pipe that's an exact fit so you don't push against the rubber), plus the tools you need to get the old one out. It's certainly doable at home, but not if all you own is a bent hammer and a screwdriver :).

Does the ECU raise the idle when you turn on the A/C?

comment Car overheating problem
A bad head gasket would certainly contribute to issues like these and might even cause them. In most cases you'd see some coolant loss, though, oil in the coolant or the other way around.

comment Left blinker quirky when braking
That's an almost perfect description of a broken wire - I'd find out exactly where the break is and carefully solder in some new wire or at least solder the break.

comment Volkswagen Golf Mk4 - Failed emission test (UK)
If you need to rebore the cylinders or deck the engine block so it's true (if the gasket surface to the head is out of true), you'll need some pretty specialised machinery for that. These things are rather big and expensive. Depending on the state of the bores (if it was really the piston rings), just honing isn't going to clean up the cylinder bores, then you need to rebore, get oversized pistons etc. Same goes for the crank if that's been damaged/worn, you need specialised machinery to 'fix' the crank. That said, you/your friend can farm out that work.

comment Volkswagen Golf Mk4 - Failed emission test (UK)
Stripping it is the cheap part :). Unless your friend has access to the necessary tools for machining the engine block, you'd still have to pay for that work and that's not that cheap at retail pricing. Same goes for the parts. OTOH if he's trying to do a really good job, having him rebuild the engine is probably going to result in an engine that's at least as good as a renman one, plus you've got the choice of parts quality that you don't get with a reman engine.
