I drive Sprinter vans at work which are restricted to 62 MPH.

Even downhill on the motorway, the vans stick at bang on 62. Same uphill too.

How does this type of limiter work? Is it some mechanical device within the gearbox? They're automatics too...dropping it down a few cogs makes the revs go almost to the limiter at 62 MPH but again the speed doesn't change (I thought it might have been a speed limiter that works on revs, but obviously not).

Speed limiters are a programme installed into the engine management system Ecu. Done through the Obd diagnostic socket.

Thanks. How does it keep the speed bang on 62 MPH though even downhill? The revs don't even drop.

It probably applies the brakes to keep the speed at that point.
