Kess V2 5.017 Red PCB Rework (R/W No Issues)
Bought a Kess V2 5.017 china clone, but no luck.
I can try to read but writing is sometimes danger.
power supply for akku. When I write flash, the ecu need a lot of power.
Searched a lot… thought i should rework the inner board.
Then i did something…
NFE61PT472C1H9L (connect ground for all of them)
1uF – 35V
220uF – 10V
10uF – 16V tantalum
Here is good quality pic from ori pcb
Finally. It works like a charm.
My advice is: DON’T BUY KESS 5.027 RED PCB FROM OBD2TOOL.COM – FAKE 5.017. My friend bought 10 units from obdexpress.co.uk – all work good, read/write no issues. This is the site he is using: http://www.obdexpress.co.uk/wholesale/kess-v5.017-ecu-online-version.html
Update: my friend did some Kess 5.017 tests:
Berlingo 9HX: only read ID from engineand works ok
PSA Bosch EDC 16: read ok
Skoda Octavia 1.9 AXR EDC15: read ok
BMW EDC17CP02: OBD write ok
BMW EDC15: OBD read/write ok
Ford Mondeo SID206: read/write ok
K-line and CAN both OK
VW EDC17CP14: read/writewith tricore module
2008 Sprinters with Edc16: no issues
Hope this helps.
