Bought a Kess V2 5.017 china clone, but no luck.

I can try to read but writing is sometimesdanger.

power supply forakku. When I write flash, theecuneed a lot of power.

Searched a lot… thoughtishould rework the inner board.

Thenidid something…

Transistors:

BCR112

MMUN2113

BC817

Murata filters:

NFE61PT472C1H9L (connect ground for all of them)

Capacitors:

1uF – 35V

220uF – 10V

10uF – 16V tantalum

Here is good quality pic fromoripcb

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 fromobdexpress.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 fromengineandworks ok

PSA BoschEDC 16 : read ok

Skoda Octavia 1.9AXR EDC15 : read ok

BMW EDC17CP02 : OBD write ok

BMW EDC15 : OBD read/write ok

Ford Mondeo SID206 : read/write ok

K-line and CANboth OK

VW EDC17CP14 : read/ writewithtricoremodule

2008Sprinters with Edc16 : no issues

Hope this helps.
