My16 - Rapid SB - Rev Limiter in Neutral

[RickTT]

Just noticed a Simply clever feature...

 

not sure on the parameters yet, but in neutral you can only rev the engine to 2500 RPM.

 

Not sure if its the N, door open or seat belt off or DPF regen parameter which causes this yet.

 

(car was mid regen when i turned it off hence the fan running. )

Let it roll a bit, rev limiter will go off

[Vtronic]

Apparently is to preserve the engine in the event of a bad shifting (e.g. Flat out on neutral instead of 2nd...).

Never tried but probably with traction control off you get full revs

It revs to the red in gear

You sure it was doing a regen? Usually the 1.6 idles at 1000-1100 rpm during one.

By the way, the 1.6 also raises its idle to ~1000 rpm when it's under 4 degrees outside.

Vtronic. It was doing a regen while driving. I was pushing the gas to the floor for the limiter

I tested it again.. In short of the wheels are not moving you can only rev to 2500 rpm regards of clutch in our or neutral.. Just a self protect system... Not tried with traction control off yet..

Got some miles to do tonight it in.. I will up date my running thread

In fact it is still limited to 2500 in neutral even without traction control. Probably that applies only to octavia vrs

They have done that for some time now.

[RickTT]

Ok... Little update..

Rev limter is in place when the wheels are not moving to 2500rpm.

If you disable traction control the limiter is removed.

Agreed, we've had trouble with ones unable to even register on the throttle blip section of an emissions test for an MoT.

[RapidPaul]

Must be the emissions test defeat device

My 3 past VAG diesel have been rev limited to 2500 rpm in neutral. 1.9TDi PD 105 Octavia, 1.6TDi CR 105 Fabia and now 1.4 TDi 75 BMT Polo. I was under the impression that the rev limiter was to stop cam belt failure during MOT test etc. But that might have been something to do with emission tests....

But in reality I rarely go over 2500 revs in everyday driving as that is the peak of the most efficient torque band.
