The car is a 1982 W123 280E (euro version) with 49,400 kms. on it.
Recently the movement and the reading of the tachometer becomes erratic and inaccurate for a few seconds, after which it goes back to normal again for a few minutes, then it becomes erratic and inaccurate again.
I've checked all the connections on the instrument panel and it all seems to be in good condition.
Any ideas on what the problem is?
I'd really appreciate any advice/suggestions.
Thanks a lot in advance.
