Had a whistling noise in the engine bay on Wife's 1.6 petrol, auto Golf.
Brake servo pipe, the bit with the heat shield on, is dangling down by the steering rack and brakes are hard (no power assist)
Cannot see where to reconnect the pipe to, any ideas boys and girls?
Volkswagen Golf IV - 00 1.6 Servo vacuum pipe - Zero
One end goes to the servo on the bulkhead, just in front of the fluid reservoir probably, the other end will go to an outlet on the inlet manifold, this one should be making a sucky hissy noise with the engine running
There are three pipes, one to the servo, one to the inlet manifold and a third which all meet at a tee junction on the bulkhead. I can get vacuum by blocking up this third pipe with my finger.
This pipe has a split in it but you can see rings in the plastic where it must have been either pushed onto a tube or had a nonreturn type valve in it. I am at a loss.
If the pipe is hanging down,then it is probably broken at the non return valve,that is why you can't see where it connects.You will need a complete new pipe.
I'm guessing there was a nonreturn type valve that has dropped off, have put a bolt in the pipe and taped up to get vacuum and off to the garage tomorrow. Thanks, will let you know.
Mystery solved, there should be a plastic bung in the end of the pipe with an option to connect to an electric pump on other variants. Mine was just the bung missing, all done by a great little garage in Oldbury, Highpoint Motors.
Thanks anyway for your suggestions.
Sorry, not a bung missing, reconnection to a small electric pump hidden on top of the front subframe, pump used on automatic transmission variants as a supplementary to the inlet vacuum, you live and learn.
