    Hi, i'm new.. and a female.. so please treat me gently.. i've come to ask for help as you lot all seem very knowledgeable and i'm in a right pickle.

    Car's only done £56k and i've got a warranty that will cover up to £1K's worth of work. I do about 50 miles a day, but always take care to let it cool down after a trek.

    Turbo was sounding louder when I was changing down in the low gears.. apart from that, was running fine, no smoke or loss of power etc. took it straight to garage after some reaseach on here as I know it's bad if it blows.

    Garage have stripped it and have just told me that something has chewed the blades.. imagining it's some rogue piece of something or other. They can't see the part that's chewed it. They did say it could be in the intercooler and want me to go in on saturday to take a look at it.

    Obviously don't just want to fit a new turbo as whatever it is could get blown somewhere I really don't want it to go as soon as the engine is restarted.

    So I guess the best course of action is to get them to look at the intercooler first?

    I've read that large foreign objects wouldn't generally get past the intercooler, is this true?

    If they strip the intercooler and don't find anything what would you recommend I do?

    Any help from you lovely folks would be greatly appreciated.

    right, well after taking advice from the garage, had the turbo reconditioned, boost pipes cleaned and intercooler cleaned and an oil change.. my mechanic took it for a run yesterday and it was fine.. I just went to pick it up and as soon as I pulled out, new something wasn't right.. black smoke coming out of back and turbo not kicking in straight away.. took it back to garage, he hooked it up to scan it and no faults are reported at all.. funnily enough, there's an a3 same year and model as mine in the garage next door with the same problem.. they took the boost sensor off that car to put on mine to test it and still the same.. they're stumped.. i've left it with them.. anyone got any ideas?

    any help or advice would be very much appreciated!

    Initial thoughts are boost leak/EGR/MAF. They need to take the car on roadtest with the scan tool connected to check the live data (Boost pressure/MAF readings etc)

    i didnt think that could happen unless you didnt service it and booted the nuts off it everyday
