Could it be a section of the 7.5mm vacuum hose 11727545323 cut to length ?

Thanks Dave ! Not sure.... Because the tube iam seraching for is in shape bent (see picture).

But out of my sight it is indeed the only possibility. By the way, the tube ist totally corrode.

I have some of the smaller hard tube #10 and it fits into the #9 perfectly if that makes sense

So finsihed replacing all vacuum control pipes, crankcase-Ventilation/oil separator and idle regulating valve.

After 17 years a lot of the rubbers was broken. In neutral position when engine was warm the car swallows ab bit because of that (think so).

PS: The price of the rubbers and pipes are crazy if you have a look what it costs years ago

I have replaced the larger hoses but not the small vacuum hose on mine, did the standard length of hose replace the small 90 degree hose?

Yes, it does.

A lot of the S50b32 engine have problems specially with this hose (number 11) which broke at my engine at the first touch after 17 years in three pieces.
