SVR buying advice

[simpleR]

With regards to what brianhpenfold said earlier in this thread -

"The cut over to the new Bosch ECU and GPF was at some point during the MY19 build.
I had a MY19 R and a MY20 SVR. The R was built in Feb 19, delivered Apr 19; the SVR was built in Sep 19, left the factory in Dec 19.
The R was full of pops and bangs; the SVR totally different"

Does anyone know exactly when the changeover was - is there a way of identifying the cars with the Bosch ECU & GPF from their chassis numbers?
Of failing that, how to physically identify them?

From reviewing Jaguar data, it differs per engine and country but the UK cut over for v8's seems to be car number 59206 and older would be the old EU6 (we'll call that the noisy version then) and car 59207 and later would be the quieter EU6d model.

There will be exceptions depending on the order cars came off the line but that's as near as I can get so around mid to end of April 2019.
