    W140, S500, 1996

    While stopping at long red signals or otherwise, I usually shift the selector from 'D' to 'N'. It happened twice that when I shifted it back to D, the RPM hardly went beyond 1500 and car took acceleration extremely slowly even when I floored it. And neither did it shift up into second. I pulled the car, put it back to N and the throttle was perfectly fine with the engine reving up normally. I drove in 1st, 2nd and 3rd gears and it was accelerating normally for the given gear but behaved absurdly in D only. I turned the car off, restarted and the car behaved perfectly normal as if nothing had happened.

    Faced it twice and it's shattering my confidence completely at every red signal.

    Any guidance would be appreciated.

    Regards

    S500 Throttle issue

    Hi!

    I saw your listing from 2010. I have a W140 S500. Now I'm having the same problem. Can you tell me what was the problem from your S500?

    Thanks

    Check the voltage with the engine running, cars gone into limp mode, any lights on the dash?

    Yes common fault on the early W140's 1995 onwards seemed to be ok.
