is it a wheel off and arch liner off jobby? I had a 17705 fault code, I recently changed a split pipe and did a TB clean yesterday, reset the code and took it for a 15 mile flat out blast and the codes not there so hopefully it's sorted. I did check all the boost pipes but the pancake was the only one I didn't check.

The car flies and pulls hard in a gears so I doubt if there is a leak.

Cheers

The pancake pipe is a alloy pipe that sits behind the wheel. It is visible when wheel is taken off and dos not really need arch liner to be removed to inspect it. I would not expect the pancake pipe to leak being alloy but sometimes the joining pipes that connect to it. One from the SMIC (hidden behind the arch liner, and one from the pancake pipe to the back of the engine turbo can leak, either way you would notice that on driving.

Yeah I wanted to check the connection onto the pipe. I guess if it's leaking it would be a massive leak?
