So after ripping my car apart and putting it back together, I think I have finally killed my electrical gremlins 
I searched high and low over the forums but never really found a solution so I am posting this in the hope that it helps others out with similar problems.
I had 3 main problems:
I thought all these problems were related as they all involved the indicators, so I pulled out hazard switches and looked at replacing indicator stalks but it turned out to be 3 completely different things.
Hope some of this helps you guys!
I searched high and low over the forums but never really found a solution so I am posting this in the hope that it helps others out with similar problems.
I had 3 main problems:
- Intermittent problem that caused my windscreen wipers to come on when I used the indicators, started the engine, driving along normally and sometimes when I shut the drivers door whilst the engine was running.
- My hazard lights failed to flash whenever I locked or unlocked the car, even though it was enabled in VAG-COM and the alarm was properly arming itself.
- My front passenger side indicator randomly decided to fail and cause that fast ticking that indicates one is not working, even though the bulb is fine.
I thought all these problems were related as they all involved the indicators, so I pulled out hazard switches and looked at replacing indicator stalks but it turned out to be 3 completely different things.
- Intermittent windscreen wiper problem - This turned out to be a loose earth connection under the steering wheel. It was loose to the point the nut on the end was almost falling off and the 2 earth connectors were just sliding up and down the bolt, hence the ramdomness of the problem occurring.
- Alarm hazards not flashing - This problem drove me mad for months and I couldn't figure out what was causing it. Then when I had ripped off the dashboard under the steering wheel whilst trying to fix the wiper problem above I noticed this:
A BLOWN FUSE!!!! And not on in the easy to access fusebox, no SEAT decided to hide some of their fuses deep in the recesses of the dashboard behind a load of wires and relays. I replaced the 15Amp fuse and hey presto working alarm indicator flashes!
- Front left indicator fault - I found out on the forum that the indicator sockets on the Leons are notoriously unreliable - I had a look at the indicator and think I found out why. The whole area was drenched in water with a pool of it round the bottom of the battery. SEAT for some reason decided to have a hole in the engine bay edge directly above the bulb holder and connector:
This was then solved with some good old gaffa tape to try and stop the leak - though I'm not sure this is the sole reason for the problem but I'm fairly sure water and electricity don't mix and can't be helping it. I think people are right and these are just dodgey connections so I also sprayed some WD-40 in the connectors and bent up the terminals inside the bulb holder.
Hope some of this helps you guys!
