Here comes with customer feedback: OBDSTAR X300 DP PLUS is ok with Delphi FIAT, but for Marelli doesn’t cover all software version. It reads EEPROM ok, but after that said EEPROM verification error. Done with other programmer (zed full).
Check the obdstar Fiat Marelli key precoding tips below:
It works absolutely fine. Obdstar is flawless with fiat. User error due to bad keys we expect.
You must use the correct remote or the buttons will do different things.
There are Delphi remotes and Marelli remotes. Both are available aftermarket. You must use the correct remote or the buttons will do different things.
If no buttons work then the key is 100% faulty.
obdstar x300 dp plus full it works very well on psa Renault vag fiat. It’s the cheapest on market. obdstar it works for me everytime aftermarket or original remote.
Chinese remotes/keys have a lot of problems with the Mareli Fiat. Doesn’t work with Keydiy or Xhorse keys either.
Best is to buy 2nd hand original, change PCF and enjoy fully working key without any issues.
Or use silca key. always silca key works really good quality. Slice key is 2/3 times price but works.
So use original/slica keys for Fiat Marelli type and chinese key for delphi.
