After some advice as I have a very dead Megane currently!!!
Been to renault they say its ECU, Sent it off to company they recommended and it has been returned as they say they cannot test it.
Have been told they cannot programme a second hand ECU to the car because of the immobiliser so can anyone tell me if this is just their way of trying to get me to spend a fortune and buy a new one or is it actually possible to fit a second hand one and if so how?
Would recommend getting it tested, the faults we have slightly gleaned from you would still suggest an ecu fault.
Unless you would like to reveal all info, of what originally happened.
What you have, and have not tried..
as i said renault have done 6 hrs on it and i have explained what car did and what renault said after that i am lost on it changing oil and filter etc i can manage but electrics are out my league
another company i contacted wanted 150 to test it so its now a question of how much to spend on it?
Well I have missed something in translation, just re-read your thread from page one to this.
All you have said is ecu, fubar, and everything is clicking,
You never mentioned Renault having your car for six hours, ( again we are assuming, you left the car with them, they did a diagnostic scan, but not actually worked on your car for 6 hours) and what their report was, other than Ecu was Fubar..
What actually happened, that the car was taken to Renault, was all we are enquiring about really...
as said they supposedly looked at car for 6 hours including diagnostic which they couldnt do as it would not connect car was with them for 2 weeks
car just died and then just clicked relay and flashed mil lamp so was towed to renault who did there 6 hours investigating then said they think ecu has been spiked!!
car was running fine in the evening then in the morning it wasnt!! we even tried both keycards and no difference
think thats it all
sorry for confusion and thanks for everyones help so far.
Do you have a multimeter,, ( we will teach you how to use it,, they are really easy to understand)
if not buy one,
If nothing else with this car, you will be taught the basics, for your next car..
Meant to add post a picture of your oval plate, but edit your vin, so only first 9 letters/characters are shown,
(need this info to show you what to test)
Ok, you will need to post your oval plate, we will talk you through what, and how to test,..
If it comes down to the same conclusion, your ECU is FUBAR, you will be no worse off, but at least nothing will faze you on electrics on a car.
Make sure you have a fully charged battery, as it will give you false/erratic readings
Bit of a long shot, have you tried getting someone to try and start the engine while you wiggle the looms and tap the ecu and engine fusebox to try and rule out a loose wire or sticking relay?
If we were to fit a second hand ECU - How would we code the injectors? We have seen that there is some writing on top of the injectors so which bit is the code that we need.
