VW Golf GTI 115bhp Exhaust Fault Finding

After the engine light coming on, I read the fault code, below:


The advice given for code 16804 was to check the inlet and exhaust for leaks… and we could hear a blowing from the engine area, so I set about finding the fault!

It’s hard to find a leak on an engine that’s running, as the exhaust is really hot! So I improvised using a camp-bed air pump shoved up the exhaust pipe!! And with the addittion of some Fairy Liquid as a substitute to “Snoop“, I found several leaks! ….along with a wet camera and very wet T-Shirt!


Cheers, Scott
