Thank you very much for the heads up on AutohausAZ. I’ve dealt with them before as well.
But I absolutely don't like to do business with any people or companies that score below zero on the communication skill scale.
So, I just ordered 3 genuine Mercedes front accumulators from Tom at the Mercedes Classic Center. Part number 126-320-07-15.
Tom informed me quickly (yes, by email) that they were manufactured in Germany December 14th 2018.
I could most probably have sourced 2018 manufactured Febi Bilstein (less expensive) front accumulators in Europe but finally decided to deal with Tom when he now came up with this recent prod. date.
If the genuine Mercedes accumulators are made by Febi Bilstein or some other manufacturer, is another question!
Perhaps someone educated here, have some “inside” information regarding this?
