Hi

Thank you for your question, my name is ***** ***** I am a fully qualified technician and will try and help you.

Yes the intercooler is a common problem on the sprinter, it normally splits a the point the intercooler hose enters it at the right hand side when viewed from the front.

This would tie in perfectly with the symptoms you have and would certainly be the first place I would check.

I would also inspect the intercooler pipes carefully.

I hope this helps do please feel free to ask any further questions.
