As a locksmith is the Poldiag a good investment vs Yanhua Mini ACDP2 with VAG MQB RH850 instrument clusters?
Pros:
Poldiag works very well for VAG MQB. It has better coverage on both RH850 5A and 5C clusters.
Poldiag is easy to do with IMMO 5A for used cluster. There is a special option in program for cloning these boards.
Cons:
You need rh850 subscription.
You have to pay a subscription for it every year.
Poldiag only works online via the server and several times a month the server is down.
Long time to open BGA, you have to be lucky for the server to work, support is practically non-existent, the developer has shifted responsibility to the users. The contact phone number is a complete failure.
Yanhua Mini ACDP with Module 33 and 34 MQB
Pros:
Done mileage & keys on RH850 no issues.
No soldering required, and even the xhorse adapters though they work are not as easy to align as the ACDP ones.
The ACDP adapters have clear alignment on the silkscreening guiding you to the correct position and are much more compact which makes alignment easier, and helps storage in a smaller work van.
Abrites, Xhorse and Poldiag they all read different format – only one file, they encrypt on they own way, thats you cant use the files from one to another as they do not recognise it, no matter what extension at the end. ACDP reads normal data and you can also save it as .bin. For example, the calculated immodata is recognized by VVDI2. There is always a problem with Poldiag.
In ACDP if something goes wrong there is an option to send the damaged file to the support for repair.
You can add many other modules to the ACDP/ACDP2 to expand functionality. For example, ACDP-2 can now also do new Mercedes and Toyota and the price for this update is not much.
Cons:
Some reported it will kill dash when reading 5A cluster for immo data, i.e R7F701402. But ACDP team will repair data.
