Hello,
THe development CVT boxes were notoriously variable - variable in terms of one box to another (Not as in gear!).
It sounds like your box is putting a higher load than expected on the engine (especially in idle area).
I'm a bit rusty on CVT stuff bnow, but it could be:
- something stuck in the box - there are a few solenoids that alter things inside the box that could increase the load - unfortunately can't remmeber the names of them (secondary..?,
- dirty oil was a problem on development boxes - that caused a lot of problems - mainly increased load and 'thumping into gear.
- there is possibly a state where when you have your foot on the brake and come to a stop in Drive, that the box goes into 'N' to save fuel etc.
- maybe that is not happening.
The ECM controls the gearbox, so its unlikely it would be controlling it to give a higher load than expected - its likely that there is something mechanically or hydraulically wrong with the box to make it differ form the norm.
Your description of the MIL and EML lamps is correct for the bulb check - after starting the engine they will remain on for a small period of time, and switch off - the EML takes longer to switch off than the MIL.
There will defienitely be a code stored if soemthing has happened (and retained for a t least 40 warm-up cycles of the car. Try checking temporary codes as well as confirmred (Mode $7 as well as Mode $3).
As I say I'm not 100% on this subject - get in touch with your dealer though. |
