Thread: Need help with my 99S3

  1. Default Need help with my 99S3

    Hey yall! pretty new to this thread as i have just recently purchased a 99 S3,
    have enjoyed reading some threads and can tell most of you are quite knowledgeable when it comes to help.
    Shes a bit old but she still runs smoothly and what not HOWEVER being the super eager and impatient bastard I am,
    I didnt get it checked thoroughly untill after purchasing it
    I took it to a mechanic.

    they listed the following;
    Stop light not working
    Indicators flashing white at rear
    The mass flow sensor has been unplugged
    Oil sump is not correct
    both inner and outer c/v boots are torn on Right hand side
    Shocks are super worn out
    right hand rim cracked on inside
    and the Exhaust is too loud

    The mechanic was a bit of a moaner as he really just complained and said I should get a mazda 3
    I'm not looking for another car to be honest, I've already spent my money on this one ,
    I am really just looking for parts to replace from list above or any general help that isn't "get a nana car"
    Any knowledge/info/links from the Crew would be super helpful thank you guys and drive safe!

    Hello Luke and welcome!
    Nice choice in car, very understated!

    Lights are easy enough, they'll just be globes. Just make sure you buy quality branded globes, not cheap crap - Phillips or Osram are my brands of choice, Bursons sell both.
    The indicators may be coloured bulbs. The '99 S3 should have tinted/coloured rear light lenses, so the bulbs should be clear. The comments about flashing white confuses me a little! If the bulbs should be orange, just buy new orange ones! If the lenses are clear, then someone's fitted FL lenses to it, in which case buy orange ones, or the silvered style for looks!

    Unplugged MAF... Interesting! Why was it unplugged?
    It could be faulty. With it unplugged, the car may be fuelling off the O2 sensors, but they're probably well under efficiency if they've never been replaced too.
    The only way to be sure is to plug the MAF back in and observe how it drives and scan it with VCDS (or get someone to help, or take it to a good independant VAG specialist to scan) to see if it throws a MAF fault.
    Fix is to replace the MAF. I would consider O2 sensors too if no evidence of them being done.
    MAF is particularly important if it's an automatic car, as the data is used to optimise shifts - they won't be as smooth with the MAF unplugged.

    Oil sump not correct... ?
    How does Mr Mazda 3 know that?
    Does it leak?
    Get a 2nd opinion or check part numbers against ETKA.

    Inner CV boots can be a little hard to find. I would normally direct you to FCP Euro or ECS Tuning for parts, but I'm not sure the 8L was sold in the US. You could source parts by looking under MK4 Golf perhaps.
    The job itself is easy enough with a bit of experience, you'll need to remove and reinstall both CVs on the shaft, and probably clean and regrease them.
    If you're going that far, I would replace the outer CV entirely - they're not that expensive and the outer CV takes all the wear and heat and grit from the wheels and brakes, it also has the hardest job to do with the angles it operates on. Loemforder is OEM, Meyle or JP Parts are good substitutes.
    If you're not that confident, you can buy whole replacement shafts with new joints. Try yellow pages or the sites I mentioned above.

    Rim cracked.
    Is it holding air?
    Have it checked by a wheel or tyre shop and observe it for yourself.
    Is it still the original 6 spoke AVUS rims? For an S3 they might be a little hard to replace. 5x100 bolt pattern and narrower offset than a B5, so you can't substitute either. Try a repairer to see if it can be fixed.
    Full sized spare the same? Swap them over.
    Might be an opportunity to buy some rims

    Exhaust - does it meet local laws? If so don't worry about it unless it annoys you!
    If it has a leak, repair it. If it needs a muffler or resonator, try a wrecker like ASV Europarts, or Unique Auto parts (Melbourne).

    Hope that helps!

    ahh thanks! that does help a lot with the lights and that, yeah it looks like they've been swapped so I'll have to grab some orange bulbs :)
    silvered style ? ohh might have a looksie! ahh yeah with the oil sump there is no leakage or anything but he just said that it wasn't right ? to be honest he wasn't the most helpful for 380$ just told me there were a few things wrong and changed the oil.
    I live in Melbourne and my Audi is a manual, with the MAF, yeah I actually have no clue why it was unplugged at all, could be a problem might not, the mechanic said he didnt even wanna touch it incase something went wrong ? is that a generally expensive job? sorry I'm a bit of a rookie with cars and mechanics and a little new to australia so my resource knowledge is very limited haha.
    Oh I see do the mk4golfs have similar shafts completely ?i'll have a look at those sites for that too!
    The rims are aftermarket, 19 inch HxR rims ? 5 bolt. I've already started look at some different rims, probably the funnest part haha
    uhhhh its pretty loud, again no leaks , very smooth tough sound but
    I fear it may be a little too loud, I'll give those 2 companies a call today thank you ! Thats really helpful thank you!

    Yeah - I think Phillips and Osram both make them. I've got them on the front indicators of the S8...

    If it passed a Vic RWC, then I wouldn't worry about the exhaust, for now...
    A replacement MAF will be about $200 for a remanufactured one (new sensor in old housing usually). That's what I did with the S8 after it nearly blew my auto up! Got it from eBay I think.
    O2 sensors are around $100. You will only need the primary sensor, if a secondary is fitted it only checks on Catalytic Convertor efficiency. I only buy NTK (NGK) O2 sensors these days as Bosch have stopped supplying the OEM plugs (although they lead you to believe they haven't).
    It's worth replacing both to maximise fuel efficiency and engine longevity.

    I'm thinking that either the Mk4 Golf GTI or R32 (or Bora/Jetta VR6) may use the same driveshafts. ASV or Unique Autos should be able to help you with both. ASV are in Campbellfield. Unique Autos are in Dandenong.

    Another resource is Imparts. They're not always helpful with cash sales.

    There's a number of websites for parts (most are US based, just watch out for freight costs and do your conversions) - FCPEuro.com, ECStuning.com, Autohausaz.com, Rockauto.com, Easy-square.com (genuine parts only, need part #), A8parts store on eBay (use desktop site so you can search within the store) - UK based.

    Forgot about the shocks...
    OEM on A4 and up are Sachs (ZF) units. S3 may use Sachs as well - they're normally painted dark red.
    They can be found ok, but tend to be pricey.
    Bilstein are more common as an aftermarket replacement and are a good substitute and cheaper.
    You can buy Bilstein from Quadrant Suspension in Berwick at very good rates.

    In my post above it reads like I suggested replacing both O2 sensors. My both referred to the MAF and primary O2 only. Secondary O2 almost never needs replacing unless it throws a code or you get a CAT efficiency code. Your car may not even be fitted with one.

    Also note that Easy-Square is in Holland and all orders are dealt with via email.
