- 2004 CLK270cdi Avantgarde
Hi all
I have recently bought a '54 plate W209 CLK270cdi with 68k on the clock. When I test drove it, a pipe had come off and it was blowing loads of smoke and making a rushing air sound (like the climate fan was speeding up and slowing down) when on the move. This was fixed and I bought the car. I am generally pleased with it as it is beautiful to look at and drive but 2 things are bothering me slightly:
1. How much black smoke should there be under acceleration? Although I couldn't describe it as clouds there is a definite plume of smoke when I put my foot down (even does this when stationary).
2. I have supposedly upgraded from a Volvo S60 D5 diesel yet the CLK seems a lot 'lumpier' than the Volvo diesel. It feels like a step back in technology and sounds so much more diesel'y than the D5.
Should this be so or could the 2 items be related and I have a problem? Could the original problem of a blown pipe have left a residue that is now blowing out under acceleration?
Thanks in advance for your advice and comments.
