Crankcase (pcv) problems of the 2019 Audi A6

I recently brought my 2019 A6 to nyack Audi for an unrelated repair, after performing their complimentary inspection the service advisor told me my water pump was leaking coolant into the vacuum hose system; and the pump, pcv valve, sensors, solenoids and vacuum hose system need to be replaced, costing $6,186. My A6 was out of warranty at that point, so Audi would not pay for the $6,186 in repairs. Engine coolant purportedly leaks into the vacuum system and other electrical components, causing contamination of the vacuum system. Leaking coolant will cause an overheated engine and possible failure of the (ea839)engine and even the turbocharger . Today I did some online research line research and discovered a class action lawsuit involving their 1. 8 & 2. 0 engine water pumps which failed prematurely for the same reason. A major class-action settlement (zhao v. Volkswagen group of America) was approved covering certain 2014–2021 Audi vehicles equipped with 1. 8l and 2. 0l engines. And now, there is a class action involving the 2. 9 & 3. 0 v6 engines; “the lawsuit alleges the water pumps are defective in Audi's 2. 9-liter and 3. 0-liter ea839 v-6s; these engines were available in nearly every Audi model on sale from the 2018 to 2024 model years. The lawsuit—larr, et al. , v. Volkswagen group of America, inc. , et al. —has been filed in the u. S. District court for the district of new jersey”. Apparently, Audi has know about this issue since at least 2018 and done nothing to try and resolve it. Please put the pressure of the federal government on Audi to settle the lawsuit, do the right thing and cover the cost of repairs. Also find a solution to prevent this from happening to other Audi owners. I can’t afford $6,186 for a repair, nor go purchase a different vehicle…. . Rock & a hard place. Please help. Thank you .
