Just found this tread and it was a huge
help as my indicators/hazards had more or less stopped working! I have a 2002 (2001 model) SE 20V and the dash is slightly different from the pictures sown, mine has some upright plastic bars each side of hazard switch so could not get switch out with bread knife/or similar without damaging switches and/or dash. So what I did was to remove the stereo completely plus the blanking switch cover next to heated rear window switch and could get my hand at the rear of the switches, pushed out the heated rear window switch from the rear, then pushed out the hazard switch (a fair bit of force was needed and did push some of facia off but pushed back on easily enough). Removed the hazard switch from loom and fitted the new replacement with Seat front. I used the tip regarding going to GSF and buying MK4 Golf/Bora switch (cost just over £12 in Nov 2018 plus was quoted £24 for a second hand Seat version from a breakers!) though it is physically different to Seat one with a plastic location pin missing off the rear. It does as others have said work fine and the
problem is now solved! Many, many thanks to the person who created this solution. An early Audi A3 hazard switch will also fit!
