slick Posted June 12, 2005 Share Posted June 12, 2005 Major brown trousers moment today! Was pulling away from a roundabout up a fairly short dual lanes section of good road, hitting 1.1 bar. All of a sudden a big bang/pop sound and then the engine proceeded to virtually die on me and judder and learch throwing out black smoke out the exhaust. Straight away 'turbo's gone' flashed across my mind so applied a little throttle to see if it would still pull away, but no... bairly moving up the road. Limped to an area where it was safe to stop at the side of the road and get the bonnet up, now expecting it to be a piston gone through the roof or something. First thing I spot is the large black hose going onto the throttle body had completely popped off. Didn't have a screwdriver in the car (doh!) so had to make do with forcing the pipe back on as best I could without loosening the jubilee clip. Was only 5mins from home so drove it back while trying to stay totally off boost, wasn't running smooth though. I've just secured the pipe back on properly and started it up, revs ok now and idles ok except what is hard to discribe.. a slight misfire almost. Theres the usual burble from the nurspec, but every few seconds theres like a lull in it with a pattern to the time it does it. Now whether its paranoia or not but there sounds like a slight rattle/tapping sound coming from the engine on idle that again has a pattern to it Could this pipe blowing off and me still driving the car for a few mins before putting it back on have caused any further damage? I've not driven it yet as I wanted to hear back from some of you techy guys first in case it could be something I'll be making worse. Cheers in advance.

Jake Posted June 12, 2005 Share Posted June 12, 2005 Intercooler pipes blowing off is quite common when you have upped the boost (by Decatting or whatever). It's scary if you don't know what the problem is. Obviously while the pipe was off the car was running on unfiltered air. Something nasty could have been hoovered up and into the engine but I think it's unlikely. You'd have to be very unlucky for that to have happened.

slick Posted June 12, 2005 Author Share Posted June 12, 2005 Yeah thanks for the reassurance, probably me looking for further issues after bobbing myself lol... I'm just off out now to look for crop circles Link to comment Share on other sites More sharing options...
slick Posted June 12, 2005 Author Share Posted June 12, 2005 All seems ok, idle was still off but took it out for a blast and it was spot on as usual. On returning the idle was perfect and the intermittent juddering sound had gone from the exhaust burble on tick over. Phew! Thanks again Jake, you should get a medal for your post answering on here Link to comment Share on other sites More sharing options...

imi Posted June 12, 2005 Share Posted June 12, 2005 Is it your plugs, or coilpacks? Link to comment Share on other sites More sharing options...
slick Posted June 12, 2005 Author Share Posted June 12, 2005 Is it your plugs, or coilpacks? All seems fine now m8 after a blast around, settled it down. I'm wondering if with the pipe blowing off and the car getting air straight in bypassing the correct system off things if it just threw a wobbly, and took a while with it all back to normal again to fully realise all was ok again. I'm not complaining as long as things stay ok, gota save before I can afford rebuilds or big singles Link to comment Share on other sites More sharing options...

This is the all-important sensor that tells your ECU how much air is going into the engine so it knows how much fuel to add. So it's suprising the engine even starts with it out of the loop Your self-learning map in the ECU would have been going bonkers trying to compensate for the very bizarre readings it would have been getting because of this, and that probably explains the gammy idle you got after connecting things back up. If this is the case it will sort itself out pretty quickly, as you have found out -Ian Link to comment Share on other sites More sharing options...
slick Posted June 13, 2005 Author Share Posted June 13, 2005 Yeah even though I'd read of it happening to others its still a bit of 'cack yourself' moment, be the same hitting fuel cut I suppose if you'd never had that happen before. Cheers for the info Ian, I gathered it would be something along those lines Link to comment Share on other sites More sharing options...
