I have read the topic about the diagnostic but

Any here knows which year was the first for diagnostic connector on the R129?
Did they start in 1989 with the first R129 or when?

Do i have it on my 1992?

You should have the infamous 38 pin connection port under the hood (bonnet) on the Right hand side of the engine toward the rear. It should have a plastic cover over it.

With a '92 he'll probably have the 16 pin diagnostic socket, not the 38 pin version.
