Hello Have if the Clio 3 Warm is always speed fluctuations as if the just before went out, the distance is every 3-4 seconds, I have read in another forum that it is the crankshaft sensor that is broken. Can that be true? Does anyone have experience with?? The car now has 40000 KM on the hump And what does this look like with the CarGuarantee?? Can I just drive to the workshop and say please replace and then drive again?? What about costs because in the Inet reads I from 100€ contractually fixed flat rate, only in my contract is nothing of which Mfg
