One month into S3 ownership and the niggles are still coming!

Indicators work fine but when you lock/unlock the car the indicator flash is very weak sometimes and fine others, also when you try to use the hazard switch it flashes once and then shuts off.

I had a similar issue with my mk4 Golf a few year back and the relay was at fault so I am guessing its the same again?

Is there a guide to access the relay as I know if I go at the black trim I WILL snap tabs!

Thanks in advance, Alex
