Thanks. :bannana: I did look at PARKERS but didn't notice the lower power models listed further down the page.
From that it would appear the 163bhp model ran from1 Oct 2002 to
31 May 2005 and the 184bhp onwards from then. No doubt there will be "slippage" related to when they started to come off the production line as opposed to when they hit the showrooms
.As far as the C class saloon is concerned it would appear a higher powered 4 cylinder engine was taken care of by the introduction of the 192bhp 230 Kompressor engine which replaced the 170bhp 2.6 litre V6 engine. The 184bhp version did not appear in the C class till the the w204 series as has been said already. This business of designating engines with "theoretical" capacity when they are all based on the same 1.8 supercharged engine is most confusing. I must say.
