Q: Fetrotech tool black not possible read Citroen c5 aircross 1.3 puretech Md1cs003 2020year. There is no access to the ECU.
Security change on most MG/MD ECU in 2020
Fetroteh tool cannot read if car sold after july 2020. ecu is locked.
After 2020 not all Expensive tools support, in fact BMW/toyota still not possible. Toyota module 74 will work upto 2020, after that UDS security changed.
