Through ownership of several 16v's and re-building them several times, its safe to say I've undertaken pretty much every job on a 16v, and if I don't know the answer I'm pretty sure I can point you in the right direction...check back soon for more technical stuff as I'm in the process of compiling more data for fellow 190e 16v owners...much of the documentation is sourced from other online resources however, I have chosen to re-host it here - just in case!!! Much of this information originated from members over on Wherever possible I have tried to include Mercedes Benz model numbers and Mercedes part numbers - hope it helps.

If you're stuck for help then drop me a line at and I'll see what I can do.
