Another "Cant connect to Ecu" problem.

[billcarr]

Alfa 156 from 98. I bought this VAG cable

http://www.ecufix.com/shop/index.php?ma ... oduct_info& cPath=1&products_id=182

Its a USB ISO OBD-II / VAGCOM / AlfaDiag KKL Interface [182]. For my 98 model 156.

Bought a registered version of Multiecuscan. Connected to my laptop USB port. Testing the interface shows all ok as Com3. When I try to connect to the ECU I get the "Unable to connect to ECU" error. I have spent hours searching the formus for a solution.

Any help or tips would be most apprecited

Hi,

Can you give us few more details about your car (engine, diesel, petrol)?
Did you test your interface from "MES > F9 (settings) > Interface > Test"?
Can you paste here your report?
Did you installed for right drivers?
Try this one: http://www.ftdichip.com/Drivers/VCP.htm
Did you test your interface with other software (like AlfaDiag)?
Can you give more details about your PC/ laptop?

Its a 98 model Alfa 156 with the 1.8ts petrol engine
Yes I have tested the interface from MES. It finds the interface on my car through my USB port assigned to Com3. Why would I need a driver when it finds the cars interface with no probs? The problem is it will not connect to my ECU. I am choosing ECU M1.5.5 wich is correct for my car.

I have not tried Alfadiag as it apears impossible to find to downloead.

I am using an Asus laptop with Windows 8

About to give up actually

Ok I think I need an adapter to make my cable work. But wich one? Can anyone help here? The car is as listed in the post above. The VAG cable is this one.

Maybe VAG interface does not work correctly with Win 8. I do not know I did not test it.
Or maybe VAG interface is faulty. I do not think so but everything is possible.
You can try to connect to other ecu, like airbag or abs. you need adapters or you need to modify your VAG interface...
