CTS model Blue or Green

[jcb]

I thought my TQS had the newer Green CTS with the rounded plug but it has the Blue square one.
I thought the green was an "upgrade" but they dont look interchangeable.

has anyone got the green one 059 919 501 A on their car?

They blue one has no "A" on the end of the P/N

They're both green now afaik.

"A" is d-shaped, no suffix is square. But ETKA lists both as green.

They changed over circa 2000 to the rounded D shaped plug. If yours has the earlier one i guess you've also got an analog clock and no oil level sensor?
