My W204 MB has developed this small leak from the A/C system that was found to be under the dashboard and needed topping gas every a month or so, and to fix it will cost 17,000-20,000 baht, so I'm thinking of using the Air Conditioning MRL-3 Super Seal A/C Stop Leak Sealer STP AC PRO Air Con Fix that cost 26 GBP to try to stop the leak and save on taking the dash board apart and the cost, Thailand doesn't have that item for sale so i got it from the UK, did anyone used this remedy and did it work or have an idea how to go about fixing this issue?...
