One dealership mechanic claims Biodiesel causes problems.
During a trip over to have my driver air bag recall take care of, my ABS alarm came back. They replaced the faulty sensor. The mechanic & the Sprinter service manager said what many have indicated here. They only replace the bad sensor and send you on your way. He indicated that they see the problem in dual tire Sprinters built in 2015 & 2016. I got the opportunity to talk to the mechanic privately later. He said it's a big batch of wheel speed sensors used during those years of production and MB is in denial hoping you'll be out of warrantee before the failures occur. He said the DEF system is causing them lots of problems along with biodiesel. Water emulsifies in bio and rusts up the fuel system internally. I asked about the 2019 Sprinters. He said he likes what he sees but that it's too soon to make a determination. He told me he would never buy anything new & improved that MB rolls out without it being time tested. He left them once in the 90's due to some poor reliability issues. The San Antonio Sprinter service center is one of the good ones. From what I have experienced, they do not try to rack up unneeded work & costs. They are thorough and courteous and strive to give you the very best service period.
