The stock coolant distributor / Y-Piece on EA113 TFSI engines is prone to cracking after many heat cycles of the engine, when they crack a coolant leak will appear. Being made of plastic, the stock part (1K0121087H) is relatively inexpensive, but overtime suffers the same issue as the original part you replace it with, rather than being a permant fix. It’s a common culprit for coolant loss on these engines. Please allow time for theses to be manufactured! We are working on getting plenty in stock ready to ship out, currently theses are made to order so please allow 6-7working days for delivery. We hope you understand this! D&G PERFORMANCE
