After discovering my intercooler has a leak and my mk4 tdi is a bit sluggish ive decided to replace it and whilst im there clean n block the egr, and possibly clean the inlet manifold. As the manifold is a bit trickier to get to is it necessary to clean this also? I'm hoping this will sort my sluggish throttle response.

I've done it on every TDI i've had,it's only 6 bolts,take it off and soak it in oven cleaner for half an hour.

Never had any bolts rounding off or any other kind of problems,also always reused the gasket without problems.

I wouldn't even consider not doing it now that you're at it anyway,i've also done catch can installs after cleaning,blanking EGR etc.Then the engine can breathe clean air.

The oven cleaner is also great for cleaning the VNT in the turbo ;)
