HI EVERYONE I POSTED THIS EARLIER

Boost problem

--------------------------------------------------------------------------------

have a problem with my cars boost, i was driving on motroway last night when i went to put my foot down an the car would only boost to 12-13 psi an hold at 10. pulled over an checked hoses to see if something had popped off an all seemed good, set of driving again an for a few seconds boosted to 20 then would hold at 16 an then went down where would boost to only 12 an hold at 10, has anyone else had this problem? ive checked hoses but everything seems good, also got no warning lights on on my dash. my car is a lcr with 56k on clock, when turn ignition on allows higher boost for a min then goes low again, would i need vagcom for this or would be able to diagnose without vagcom? im in bordon so if anyone near has vag com would help. an if anyone else has had this sort of problem what did you do ti fix it, and i have searched but cant find this problem, thank you


I HAVE LOOKED AT THE CAR EARLIER AN THE REAR DRIVER CALLIPER SIDE BOTTOM BOLT HAS WORKED ITS WAY LOOSE, WAS WONDERING IF ANYONE ELSE HAS HAD THIS PROBLEM? I HAVE ORDERED NEW BOLTS. THE DISK IS A BLUE COLOR, DO YOU THINK WOULD NEED NEW DIAK AS WELL IRS ONLY 8 WEKS OLD SO IF CAN STILL USE IT WILL BUT IF NEED TO BUY NEW ONE WILL DO THAT,

HAVE POSTED SOME PICS BELOW TELL ME WHAT YOU THINK. I WAS DOING MOTORWAY DRIVING AN DIDNT FEEL ANY DIFFERENT BOOST JUST WASNT GOING AS HIGH I THINK BECAUSE THE BRAKE WAS STUCK ON WOULD THIS STOP IT BOOSTING SO HIGH?

that disk has overheated a bit

You were flipping lucky mate, could have been a bit scary that one.

 

[1.9...stefan]

hmmmm... looks like it may have been at a slight angle poss rubbing for a while... looking at the rust on the threads may have been slightly lose for sumtime... a similar thing happened to me but looks like i caught it before you.

 

[paul-murphys]

so you think disk will be ok or should i renew? ordered bolt an got some mega locktite.

 

[LEE69]

Disk should be fine, very strange how it come loose, not pissed anyone off lately?

 

[paul-murphys]

only person pissed off was the mrs with buying more bits for car but she wouldnt no what to do. why would this stop the car boosting high though, i no would be more stress on engine but cant see how this would stop it boosting so high,

 

[LEE69]

Yes it would, be rubbing.

 

[paul-murphys]

i can't see how this could affect the boost? I no would put more stress on engine but makin boost less is a bit strange i think. Any ideas anyone.

 

[LEE69]

It's holding the car back.
It's a binding brake, of course your not going to progress as if it was free.

 

[paul-murphys]

but would have though boost would still peak?
