Does anyone know when VAG changed to supplying the colder '7' plug as standard?

I didn't think the NGK they are now using was any colder than the original Bosch ones...  :confused:

Ive seen a few posts on here saying that they are and even on JKMs website is states they are now one grade colder.  I fitted some new OE ones last October and dont want to go out and have to take one out to check to see if mine are the colder grade plug.  So I was hoping that someone on here would know the change over date.

I have just checked my receipt and the part number is 101905631H as listed for my engine.  I have just read another thread on here and that states the correct spark plugs for the car is actually 101 905 631 B and that the plugs I have are meant for higher power variants and it may cuase damage to my pistons?  Is this correct? I bought them from TPS and thyey were the ones listed for my car.
