Not reaching max speed

Hi All
I am a new member hope there is someone on this forum who can help.
I have a Megane dci 130 with 25000km on the clock. Prior to its first service I took it on the open road and booted it. Max speed it reached was 170km (3200rpm) as if it was governed. Renault checked it out and said there were no fault codes and reset the ECU. This has made no difference at all!

Another thing I have noticed is the accelerator pedal has two stages. The second stage can be felt at about 3/4 of pedal movement. This second stage has no affect on power at all. Is this a fault or is it normal??

Steve

These are fly by wire, there is a resistor on the top of the pedal, you could be having some kind of issue with this, the 2nd stage as you call it could be a break in side the resistor or perhaps contacts have burnt out, not sure if you can get them on thier own you may need a buy a complete pedal.
hopefully this may point you in the right direction, we suffer from fluctuating acceleration in the UK when these pedal play up, maybe your has past that stage and moved on the totally knackerd! as said may be worth a look.

the second stage of the accelerator pedal is normal. It is to overcome the speed limiter once it's set. (Providing you have cruise control/speed limiter).

(A relative had a 2004 Scenic II with the two stage accelerator but no speed limiter so it's possible)
