    Hi All,

    I have been a member on the site for a few years but never really spent much time on here due to not owning a BMW. But now I have managed to get a car i have been after for a long time and this is a E46 320d M sport 150bhp model in silver. ALso got it at a bargain price due to 198,000 miles on the clock but it has got dealer service history up to 150,000.

    I have looked into the common problems as it was missing power and first job was to do the swirl flaps but whilst doing these i noted the EGR was a bit restrictive so cleaned that also went ahead and cleaned the inlet manifold by submerging in white spirits for 24 hours. It now ticks over fine but it's not on the road yet so not been able to take it for a spin. WIll upload some pics when I get home.

    Also thought i would check out the crank case breather and it already has the vortex one fitted so that has justified the purchase of a performance panel filter as the air filter is filthy. All that is left now is an oil and filter change fuel filter change and a new set of front tyres.

    So here are the questions
    1. What is the best performance panel filter?
    2. What tyres do people rate?
    3. Any other common faults?

    I have got plans to try and hike the power on the car but not for some time yet. But current plans are Panel Filter, De-Cat and custom S/S Exhaust, EGR blanking, Remap and possibly a larger Front mount intercooler.

    Also my Dad is trying to sell a 2000 E39 523i which I will list in the For Sale Section

    That's it for now but just thought I would say hello

    There isn't a 'best' panel filter, K&N are oiled so that can play havoc with the sensitive MAF sensor, OEM are good enough
    but if you're deffo you want one look into Pipercross filters as they're fitted by forum tuner Motech.

    Tyres - Falken FK452's and 912's have a good rep, vredestein ultrac sessanta, Conti's, Michelin Pilot Sports all depends on your budget.

    Faults - Radio not working when screen demister is on, brake callipers sticking and usual steering bushes
    failing due to wear and tear.

    De-catting may become a problem if new MOT rulings are strictly adhered to, if you have an EU3 engine then EGR bypassing
    won't be a problem, whats the build date of the car?
    iirc if you increase the volume/size of the intercooler you'll need to upgrade the turbo or it'll suffer from more turbo lag.

    welcome back and hth

    Is there any side effects at all from removing the swirl flaps??
    Just purchased this week a 2003 E46 320d 2.0 Sport with 78000 on clock.
    Its my first ever BMW and love it already, and dont want to be modifying it to much as its almost in perfect condition, just want to do the right things.

    A very small number of members have found a drop in low down torque after removing the flaps (I didn't) and tbh the risk
    of swirl flap ingestion is probably minimal but should it happen the rebuild costs can run into £1000's as another unfortunate
    member has recently found out...2004 E46 320D - Swirl flap damage, what to do?

    It does happen so in my mind at least "remove the flaps and spindles = removing the risk"

    Here's a pic of her and also of the EGR when I took it off and the other once it had been cleaned. I don't think it has been cleaned over the last 198k.

    The reason for the biscuit wheel is the tracking needs checking as both the fronts have ran off on the indside so getting some Falken FK452's fitted tomorrow and she's not on the road yet. Then it's time for a sevice and MOT next week.

    Please do as I'm new to this as well. Be good to learn how to keep these cars on the road.
    For all its faults the E46 varients we have are good looking/handling cars.
    Seems this is a good forum to be on.

    Hi and welcome along to Bimmerforums UK, it's good to have you on board.

    Cats won't be in the MOT for diesels, so removing it will be fine for now...... it can't be failed for not having one fitted.

    I thought as much for the CAT as currently they only perform the smoke test rather than the emissions test. ANd as far as I am aware the only reason they fit the EGR and CAT on diesels is so they get better emissions figures when selling the cars and they are nothing really but restrictive and a nuisance in my opinion.

    Does anybody know if an enlarged exhaust bore (not Tail Pipe) may help with performance by allowing the engine to breath more freely?

    Only if the exhaust is designed for the car, else you will lose exhaust gas velocity.
