Now, this may just be because I've never driven an Auto Diesel before, but I have noticed something on my mate's car that I'd like an experienced member to confirm for me.
When pulling away from standstill, depending on throttle position, the revs climb to 2k, or 2.5k, and appears to be slipping before the roadspeed matches the revs and it locks up and then acts 'normally' beyond this rev range and through the gears.
On my petrol E320 the revs don't climb anywhere near 2k and the torque convertor appears to lock up a lot earlier than the diesel equiv.
Is the described behaviour a feature of the diesel engine/gearbox characteristics, and quite different to the petrol engine, or is there possibly a problem with it?
