    Just out of interest how much would it cost to fix or replace the turbos if they were to go? Not at main BMW dealer but at a good indy or turbo specialist.
    Any ideas?
    As you can tell i'm a little concerned even though i've no reason to be.

    Doesnt sound too bad, i tought it might be more like 4 grand or something. Due to fact that wife drives 95% of time turbos will barely get any hammer Is this a good or bad thing?

    I'm surprised more people don't go down the rebuild route.

    All that needs to be done is decoke the insides, change the bearings and seals, put it back together and rebalance.
    The vane control would need to be cleaned up, they seize up occasionally but generally the mechanical controlled turbos should cost much to fix up.

    The later electronic actuated turbos are apparently so awesome that they can't be repaired, and must be replaced as one unit.

    There has been a few places that have mentioned electronic repairs, and it's more likely that the electronic actuator will die rather than the bearings will wear.

    Thanks 'The End', but does this mean that on my 335d the turbos can generally be repaired at less cost than replacing the whole unit or vice versa?
    Sorry but i'm not really very clued up when it comes to the more technical terms. I'd like my mind putting at ease before the remap.

    Parts roughly cost £1000 plus labour.

    They should be.

    A turbo doesn't wear out in the same way a house doesn't wear out.
    There would just be a few parts, and in this case, it's the bearings.

    The only way I know of totally destroying one is if the bearing is worn, and the shaft eventually cuts it way an oval hole, but again rare.

    On most other cars, I see people rebuilding turbos as a matter of fact, but BMW is always buy new or ebay.

    All sounds positive, thanks very much.
    Never even considered costs invoved with repairing such things when i bought the car. Untill I joined the forum i didnt know there were so many things that 'could' go wrong. Think, as i've said in a previous post that i've become Paranoid!
    Think a warranty is the best thing for me but that itself is a minefield.
