hi milky, normally they only erase trouble code if the engine@cvt sign appear when there is no fault with the car, maybe due to some glitches between sensors@ bugs. Normally they just reset it to default. But in ur case, u r having some problems, and they shud investigate the fault by referring to the trouble code. Ask them also to check the ecu connector and bracket. I'm not sure whther they r reflashing@just reset the ecu using padt. If reflash, they have to use laptop.
Please send to any prtn@eon branch for futher checking, not authorised dealer coz they normally dont have the faclities or enough expertise on trouble code.
On bosch hu, previously there are 2 oem for prtn, bosch(blaunpunkt) n clarion, but mainly is clarion. So, they actually try to use bosch coz many like gen2, savvy, persona, exora n saga using clarion, so, try something diff n great bargain offer by bosch since they r also supplying the esp, tc,abs, ebd sytems on preve.
U r right about clutch based cvt versus torque converter cvt. Same as single clutch(amt), dual clutch at versus torque conv at, which torque conv based still the smoothest operator among all.
When developing cfe n especially iafm+ variant which derived from cfe development, one of the way to make the engine efficient is to reduce@minimise powerloss through optimising operating temperature n using clutch based cvt besides other things such as 32bit ecu n torque based where as still many other manufacturers still opt for 16bit ecu to reduce cost especially on low end variant n na engine. There r still some soft turbo equip cars using 16 bit ecu. Less powerloss, more efficient n will translate better fc.
But since cvt based gbox make it easier to overrev than normal at, it seems the feedback from consumers, even its better than previous engine, but still not something to beat.
So, i think, if any prtn staff hear this, maybe try to do what other manufacturer do right now, power of mind, by using econ indicator. It does prove it manage to make the fc more efficient coz drivers' right foot is well control, as famously quote, fc is depend on right foot. I hope that they can come out with that in future product.
If any has driven any campro, campro iafm@cps engine based, it takes time to reach normal operating temperature compare to cfe n iafm+ during morning start. I heard also punch is continue doing their rnd in software dept to make the clutch work as efficient as any torque conv based. Hope fully they continue to release latest update on cvt adaptation which they r doing it for the hatch version.
But i hope that everybody remember that preve is a heavy car. Iafm+ couple with a manual version for saga,is actually better than cvt counterpart on overall performance, but for preve, between manual n cvt iafm+, cvt has an edge due to infinite ratio, so, the gbox easier to adapt it ratio with weight n etc, but for manual, u need to keep it at strategic powerband before shifting.
Jerking@rocking is exhibit at low speed, but it will be less through times, but still there. Hopefully punch will provide special solution, i think on hardware part to make it as good as torque conv. I heard honda n nissan, will coming out with cvt clutch based in the future.
