Hiya.

Hopefully a simple question here. By UK standards it was cold this morning with lots of ice around when I took my toy to be serviced and although she started and idled fine, she seemed very very sluggish to pull away - until she was motoring and then pick-up when pressing the accelerator was OK. Not great, but OK. The gearbox is set to W.

I did get a OBD scan done befoe the service and it did show a code about the accelerator pedal location sensor so maybe that's on it's way out, but on the road test following the service there were no such issues - performance was fine.

My question therefore is - Is there a feature whereby acceleration is limited when it is icy to protect you?

If not, then I'll have to investigate the sensor....

Thanks in advance.

Jeff - the switch is at W - Winter mode. The throttle response was much laggier than previous drives in this mode but only when pulling away from a standstill. I've not had it in Summer mode for a while - it's been too wet.

Went out for a drive this afternoon - all seems well with the throttle now.

Thanks

Normal. Catalytic converters do not work until heated up. It keeps the RPMs high to heat them up faster. Its an emission's thing.
And ... Relax. Thanks @ichris93. There wasn't any problems on our 40 mile trip in the afternoon, anyhow. I'll keep an eye on it and see where we go.

I don't know if anyone addressed this in the post, but the "w" setting is for "winter", and by design cuts the amount of torque you will get to the rear wheels. I only know this as a first time owner of an R170, I was thinking the "S" stood for sport, so have been driving around for the first month in "W", and occasionally switching to "S", thinking it was to make the transmission more responsive.........DUHHHHH......
So just paging through the owners manual found that the "W" setting has my car starting on in 2nd, and shift points are not as radical. Thus more sluggish by design I guess you would say. Needless to say, I am driving in the "S" mode as I should be, and happy with the result.
As they say, "When all else fails, read the manual!"R)
