 Hi everyone

I am in a bit of a headscratcher situation. I recently checked my 2.7 HDI's eolys reservoir and it was completely empty. Bonedry. Strangely I never got a display message stating that it is low on fluid. I tried to access the ECU controlling the dosing of the Eolys but Lexia/diagbox cant access the dosing system's ECU. no fault codes show up anywhere. I want to refill the system but first want to figure out how to reset the counter.

Can someone please help me figure out what is wrong?

Thanks
Corne

 Hello Corne,

You have to access the ECU to reset the counter. Does the Global Test on Diagbox recognise the presence of the ECU?

Best regards,

Phil C.

 Hi Phil.

That is the problem. It doesn’t recognise the ECU

 This is very rarely a software problem and even more rarely a contact problem of the OBD socket.
It is most likely a bad China VCI. The Citroen C5 and C6 are particularly affected.
It would therefore be convenient if a forum member with a DIAGBOX in your area could be of assistance for testing.
Or you can go on holiday and drop by my place in Würzburg (Germany).
