Hi,
I have been struggling over the last few weeks with no turbo from my td4 over the weekend I got to the back of the engine and found no vacuum coming from any pipes. today I removed pipes from vacuum reservoir and joined them together using a straight through adapter and I got all my turbo power back. I have blown and sucked through the reservoir and it seems to be blocked. Does anyone know if I should be able to blow straight through it?

Cheers gaz
 
the pipe that goes over the gearbox rubs on it and then you get a hole and then no suction the worst part of that is you do not have good brakes either as you have no vacuum
 
yes I noticed it had been rubbing, it has worn down but no hole yet.
But can you blow it as I cant with mine, I have ordered a new one from BMW for £22+ the dredded.

Thanks for sharing I have been looking at this on my FL1 now I know what it is, do you have a link for purchasing please
 
If its getting blocked, then there is a problem with the system....missing the wee filter that dangles on the end of the pipe, or one of the pipes is worn through...either will allow dirt to be drawn into the system, or worse if someone has connected the other end of the filter to the front diff breather tube, which I have seen a few times.
 
I had to replace my vaccum reservour , due to the vaccum pipe that goes from there, across the engine and down to the turbo was split, on removing the old vacuum pipe I broke the end of the vacuum reservour and u can indeed blow through them ,

I got a silicone vacuum hose as I needed around 2 metres and most of the ones online wernt long enough

ended up replacing all my vacuum hoses , due to there age and also found where they had touched the engine , burnt holes through them

it's fidley getting the old vacuum pipe out as it runs by the injector wiring loom , easier to remove the air filter assembly , so u can then tuck it neatly

I also got myself some washing up liquid , mixed it with water and put it all around the joints with the engine running to see if it sucked any of the soap in , it didnt so I knew I didn't have any leaks anywhere , also made sure all the clips were on securely

when you blew through it did you cover any holes ,I am just wondering if that is wrong with mine as top speed is getting worse. Did you buy the tank or just new pipe which I think is 4mm.and where did you get it from.

bought the tank from my dealer , yes the pipe is 4 mm silicone hose need at least 2 metres to go from the tank across the engine and down to the turbo selonoid valve

got it from this company , ordered 3 m so I knew I had enough for the back of the engine

had to replace the tank as I broke the end off whilst getting the old vacuum pipe off,

I also made sure as it went down the side of the engine onto the turbo unit that it went into the clips and used cable ties to ensure it didn't touch anything hot again ,

ref the pipes I replaced all of them as they were either frayed or holed , the ones at the front of the engine under the egr were the worst

when I removed them I put them into a bowl of water and used a foot pump with a small nozzle attatched , bolt in the other end to prove that they were indeed holed , after I fitted new ones, ran the engine with all the pipes connected, used some soapy water onto all the joints to see if any bubbles were sucked in to ensure they were all nice and tight and not leaking

didn't like to put the foot pump onto the pipes whilst fitted onto the engine just incase the pressure damaged any seals etc

found the brakes improved and also the pick up of the engine was better

don't know if the question was directed at me , lol

hope it helps abit mate

my fault with the turbo not picking up properly was due to the map sensor which is on the side of the inlet all the hole was bunged up and after I had cleaned it up the problem was no more. but top speed is still a problem it is down to 90 now at one time I could get 100-105 my old one used to do 115 but I am trying and trying to find out why it will not go over 90
