Hello all,my first post on the forum,although ive been a member for a while.I have a 2007 Stilo 1.4 16v Active Sport that i bought 9 years ago.
Until Saturday it had never let me down or given me any issues,hence why i`ve never needed to post.
So on Saturday,went to start the car and its turning over but wont fire.(ran fine before this).Looked at the dash and it has the engine management warning lit and the padlock warning,along with the ominous "check vehicle protection warning".For some odd reason the outside temp is showing -40 aswell (its about +15c).
So i do lots of reading up about possible causes,pull everything apart,clean and check all contacts on the battery,the computer,the fuse box and the ECU.Use spare key and try a antenna from my daughters Grande punto...Still the same.:bang:.
So while i was doing all this,one thing i noticed was everytime the battery was disconnected and reconnected,when the ignition was switched on,only the engine management light was lit,the padlock and CVPS error was not showing.However it would still not start and when the ignition was turned off,then on again,both the engine management light and the CVPS errors were present.(shouldn`t the engine management light still go off with the CVPS error?)
This leads me to think that it is actually the ECU module under the bonnet that has gone bad and is not communicating with the main computer.
I doubt it being the main computer that is bad as there is absolutely no other issues (apart from the errant outside temp reading)..The engine management light did come on occasionally before this episode,however it did not affect the running of the car and went away on its own accord.
Would anyone agree with me on this,is there any other instances of the ECU failing?as im about to order a virginised ECU from ebay
Thanks in advance.
