No and no.

Relay type on older BCMs is written in that thread too.

I would not fit a relay that had been used before, cost is only a few Euro for new relay.

Board 6Q1937049F looks much less safe to solder than older ones. Probably i will buy used 6Q1937049F - cost around 50 Euro. 

Looks similar to me, but not easy to desolder and clear the holes. Needs a bit of skill and suitable equipment. 

Photos of relay contacts:

 

I opened relay body. In my opinion one terminal was sticked to ground terminal. After some pushes it sarted move. To make sure I cleaned termainals with 2000 sand paper, there wasn't oxidation on paper,  and finally wipers work on second and third gear. Don't work on interruped gear.

I have this car for two days and I don't think it has automatic wipers, which on only when it's raining. How to check if car own automatic wipers, or what else can be broken? Car has standard manual mirror without any sensor/cables.

Intermittent wiper non-function is sometimes caused by the bonnet/hood not being properly closed.

I don't know if any Fabia in 2008 had automatic wipers.

Thanks, I will check bonnet, later.

Wipers problem has been fully solved.

As I mentioned before, in my opinion right arm in relay was sticked to uper (ground ?) terminal.

 

And my wipers didn't work in Intermittent mode because somebody made jumper in hood switch. He probably was faiting with wipers problem and wanted to cheat the system, but did it in opposite way. 

 

After remove jumper all wiper modes work properly. Hood switch is also good.

Thank you guys.

I also made the wrong assumption that the bonnet closed contact would be normally closed, open circuit on opening, not so as Pete patiently explained to me.

 

Which as a safety circuit is a big surprise.

 

My jumper was more artful but equally redundant. 

Bonnet switch is for alarm function rather than safety-related, I think. Our Fabia lacks an alarm, and a bonnet switch.

That’s a handy diagram - is it from factory service manual? I also checked motor before removing control module and it was fine so suspected relay.

 

Well done on getting board out. You must be more flexible than me! It was too awkward without removing seat but that’s only a few bolts and a connector.
