Hey, all fellow L-drivers:
Just swapped out my last 2014 500L Lounge DDCT for worry of future issues with the trans. Went with another 2014 500L 6 Speed manual with 43k on it, a steal at $9.5k. However, I did not purchase it from a FIAT dealer, but a CDJR dealer in Columbus, OH. No warranty from the dealer, but retains its FIAT Factory 50K/5YR.
So here's some background. Salesman went to start it and it was dead as a doornail. Jumpstarted it and it ran great, no drain issues since. Upon preliminary drive, I took it fairly-gingerly, not really being familiar with the Fiat stick (used to MINIs and VWs). No troubles.
I get it home from Columbus, a 2 hour freeway drive, and it runs seemingly fine, other than a slight left-pull.
But I leave again that evening for a short drive and really lay into it to see what it's got in comparison to the old DDCT- it reaches the beginnings of spool and it fumbles all over the place, jerking and waffling until I back off the gas. You can't even hear the turbo wind up, unlike my last auto. If I don't exceed maybe 50% TP, it runs smooth as silk, even at idle. no MIL, no codes, not even history codes. Just jerks all over when you lay hard past 2,000RPM. otherwise I can accelerate to 3,500 without engaging boost and it runs great. Feels like a boost pressure control problem, but no codes indicating that.
I've read of turbo wastegate valves sticking on these, and that was my first thought... I reset all memory/learn procedures in the ECM to no avail.
If anyone has had similar issues, please chime in. When you don't have DTC's to point you anywhere, its maddening.
Thanks!
