Hi all, I have a 2008 2.0Tdi 4x4 170 Elegance and I was just wondering if everyone else who has the same car has the same thing happen when slowing to a stop. mine for the first 4 or 5 seconds will tickover at about 900-1000 rpm and then drop to 800 rpm, if you blip the throttle it will always then go down to 800 rpm but it will do the 2 stage tickover every time the car is moved, the reason why I ask is my car is quite noisy at 900-1000 rpm and then is quiet at 800rpm so its quite noticible, is this the same for everyone especially the noisy tickover at 900-1000rpm. the noise sounds like a belt/pulley noise, i've had it looked at and they told me it was normal, is it?

Another thing whilst looking into the noise if found that when the car is stood still you can't rev the engine over 3500 rpm even with your foot flat to the floor, theres a sort of limiter which is kinda cool.

Cheers all

Cars nowadays have anti-stall, and when in neutral they don't rev to prevent engine damage.

Also when the DPF is regenerating it will rise tick over to about 1,000rpm.

I've also notice that depending on the load from the climate control the car will idle at 1,000rpm. Select a different setting on the climate control and it drops back down.

When in motion at slow speed, the engine will maintain around 1000rpm as an anti-stall tactic which means you can drive in 1st gear with no throttle input at all, once you stop the revs drop as the anti-stall is no longer required. My 2005 Octavia was the same, and it was great in slow traffic. Another cause has been mentioned in the previous post, DPF regen as that requires the increased RPM to maintain the regen. The rev limit when stationary is also be design, you can override this though since when MOT tested the car is revved to maximum RPM and held there as part of the smoke test.
