[Dazkeirle]

Hi hopefully someone can help.

Have a clk 220 cdi.

Noticed yesterday car was loud on boost, whoosh noise from left of car.

Today car went to into limp, had odb connected and these were the codes. 0299,, 2395

I've done some research and this appears to be commonly a server split 4inch intercooler pipe.

Only photos online are now dead links and I can't feel any cracks or splits in any pipes that fit this description.

Please can somebody tell me if they agree with diagnosis, how to locate pipe and part number for replacement for

Thank you so much.
