Your p*****g into the wind without vagcom.(or equivalent if there is one? Not seen one yet) Get it on vagcom, check over the sensors, see if your not getting a value from one, or if its giving you utter poo. Like for instance my coolant temp sensor went faulty, dash was fine, but ecu thought it was minus40'c and was screwing the fuelling not allowing it to start.. Can be the cheapest simplest thing causing a huge hassle... I've seen 15+ fault codes caused by a corroded earth point!
Without the proper diagnostic equipment you could throw hundreds and hundreds of hard earned cash at it and never fix it.
From what you have said, does the fuel pump prime when it won't start? Or is it turning over with fuel and not starting?

Vagcoms a code reader in simple terms but can read anything and everything
like a snap on obd reader a Garage would use mucka
From what you said mate it sounds like a sensor but which one is the hard question. Think the next step is code reading or change a sensor and fingers crossed.
Does it just turn over when it wont start

Ill start by throwing a crank sensor on tbh mate
Sits in the front of the block. If your looking at the engine bay with the bonnet up its the bottom right corner nearest the gearbox
Think its the middle plug of the 3 big plugs that sit above the oil filter

Heres pics of my spare engine. Plugs sit just behind the dipstip brown grey black
Middle one grey us the crank sensor
Just incase you do try it gives you idea where it is

The crank sensor is referred to as the g28 sensor. Order by that from either a dealer or tps. A cheap, non genuine one will stop the car revving properly.
Held in by an Allen key bolt, and pull it out with pipe grips. It's clicked in. Easy job if you remove the oil filter.
Sounds like you would benefit from a full scout over everything in the engine bay. And clean all connections and earths! Then replace ALL vacuum tubing for new stuff, as 85% of problems circulate around leaks of varying sorts from pipes that are now old enough to be perished beyond useful. A day spent cleaning all connections and a Tenner spent on vac hosing is better than 110 quid on a g28 impulse sensor ( engine speed sensor.)

When speaking of vagcom (or vcds, its the same thing) this is what we have.

Your free to buy one also. This is the real deal! View every sensor on the car... From engine to abs to airbags to central convenience, to the stereo and many many more! Every single one!
Main point is you can view any sensor that is there, allowing logging of info while driving also it really is the diagnostic tool for any VW AG car!
The cheap eBay unlicensed ones are limited in how many things you can view and iirc you can't log with it either.

You should undo all the earths and wire brush them.. Stop any future problems. If its old enough for one to do it, all could.
