vacuum leak . on one of the small black pipes

[TREVOR 0191]

I changed the vacuum pipes yesterday with new pipes while doing that i found a split hose which may be the problem as the hose gos the bottom turbo to the front of the car I think it is to do with airflow to the turbo not sure.

sounds like the n75 valve pipes.

Late update but better late than never after all it was Easter weekend, I replaced the s shaped hose with the two metal things at each end it was a brand new one for which I was quoted £180 over the phone but with a bit hum and har i managed to get it for £93 still I thought that was pricey anyway the result was good and all is well my Passat 130 sport is as it should be.
Thanks to passat 130 tdi for your replys to my post.
