"The only problem I have found with the entire clk55 swap is the rear windows not being recognised by the EIS, I think the only way around this will be to make the CLK55's ECU virgin again ,use the C43's EIS and recode the clk55 ECU with C43 VIN and let them get married... we will see "


Guys, just wanted to tidy this loose end up. the fix for my rear windows was to install EIS/ECM/ESL from a 00 C43, and then code it to CLK55
