Following hotrodders post above, I had an issue when I attempted to source Sachs coils springs for my CLK.
Being a long-term BMW maintainer, I have high regard for Textar brake products and ZF group products (ZF,Lemforder, Boge and Sachs), so when I needed to replace the rear coil springs I looked up the ZF webcat for the Sachs part number.
I found a comment there that stated 'not for UK' against all likely Sachs springs. I emailed ZF customer service to ask how I purchase Sachs springs in the UK. They replied that ECP are the Sachs spring distributor and I would have to contact them.
As usual, the ECP website was not sufficiently specific to positively identify the spring I needed (MB 210 324 36 04) so I phoned them to crosscheck their part number against the MB number.
When I aked them to confirm the manufacturers number of their most likely Sachs spring, they replied with a manufacturers part number that I didn't recognise and certainly not a Sachs number. Afterwards I found out it was actually a Lesjofors part number.
I have nothing against Lesjofors, but did read they have been buying spring makers in Slovakia and Asia. I therefore bought my springs from MB.
I future I will be buying any Textar and Sachs parts I need direct from Germany as it seems there may be some doubt that the UK sourced parts are actually the brand you expect.
