Sneaky little Boost Leak

[Dingo]

Cars not quite been running 100% for a bit, boost gauge stops at 1.4 and moves around a bit, it used to hit 1.6 and stay steady, so I've did a leak test and could hear something underneath at the back of the IM, so I whipped of the TB hose only to find the smallest of holes in the pipe.
I'm quite chuffed really because I've done loads of leak tests on her over the years and never found any, so I had a small doubt that I was doing something wrong, but the noise is quite obvious really, even from the smallest of holes, new hose on order from Audi £29, Happy days.

I hate boost leaks, had a nightmare over the last few months with them, maybe a picture gallery of boost leaks would be a good thing to have. I've got lots to add

I have had to replace that hose twice in the time dat I have owned my car. someday I will get round to replacing everything with silicon.

IMO non of the silicon hose's available for our cars fit the throttle body as well as the orginal Audi part which has an internal lip to locate it properly. I had a Samco set and I didn't like the fit of that or the MAF hoses so I sold them and purchased new one's from Audi/Roose instead.

The one under the ISV ( short right angle bend to IM floored me - not part of the original samco hose kit replacement set ) - sold the car with 2 spares ! Always careful removing it ( I had a spare ISV ever 'lubed ready to be installed ) but they always split on the back curve....

They are NLA now so be careful with them!

I fitted an AAN throttle body which has a longer connector for the hose which helps, the connection to ISV pipe is still a bit short on the Samcos though
