ULEZ emissions W208 CLK 430 - Some are exempt ?

[MikeInWimbledon]

I got a clk 55 amg , and I’m trying to make it ulez , another friends they have exactly same car and is Ulez , if you can point me in the right direction , cheers

What makes you think your CLK 55 is NOT Euro 4 petrol and therefore Ulez compliant?

An “elderly” (pre-2000) number plate?

Euro 4 did not start until the end of 2004....it might comply with ULEZ as a Euro 3 car as far as NOX goes (and that's the only one they care about)..but it can't have been be built as Euro 4 in 2000.
