In conclusion:
SD C4 Plus Doip is the not cheapest, but it owns the advantages below:
1.It’s optimized on the basis of the original hardware, to solve the problem of the dead whiteboard caused by the upgrade test in actual use.
2.The official diagnostic test model is continuously updated to support all old cars and new DOIP models with functions exceeding MB SD C4, C5 Doip and Benz VCI C6.
3.All C4 PLUS are tested by 24V supply in 24 hours without interruption before leaving the factory. More than 90% of the IC is guaranteed to be original, especially the main control and relay are guaranteed to be 100% original material, which improves product stability and reduces use. Failure rate, the product has undergone multiple rounds of self-diagnostic tests before leaving the factory, real vehicle CAN and K-line ECU tests, programming and coding, and DOIP tests to ensure consistency of all products before leaving the factory.
That’s all! Hope it helps!
