This is so common a problem a class action settled against Audi where owners who paid for clogged drain repairs or had water damage got 100% of their money back and free damage repairs. We are bringing identical case for Acura, BMW, Mercedes and Lexus owners and expect same results. Send me an email or call 1-800-279-6996 if you're out of pocket for repairs or had water damage to make a claim. Jos. Santoli, Esq.
