    Hi Folks

    Ok first things first, great site very informative, I am new to this forum and a new owner of an S4 2.7TT (what a car!)

    Anyway problems I might be having, not had a S4 before and I think the power/torque might be lacking above the 70-80mph mark, upto this the car accelerates like a rocket but after that it just creeps up, not as quickly as I would have thought. I then did a VAG scan with the trial version and it chucked out these following codes.

    VAG-COM Version: Release 409.1-US

    Chassis Type: 8D - Audi A4 B5
    Scan: 01,02,03,08,15,17,25,35,45,55,56

    -------------------------------------------------------------------------------
    Address 01: Engine

    Component: 2.7l V6/5VT G 0002
    Coding: 05611
    Shop #: WSC 00165
    7 Faults Found:
    16486 - Mass Air Flow Sensor (G70): Signal too Low

    Shop #: BB 24334
    No fault code found.


    I have done some research and found that the codes with Register/Activate seem to be EGT errors, would these be caused by the MAF or Lambda sensors or would there be a fault with these too?

    I will be having a pressure test done soon when my mate has time!

    Do you have any pointers for me?

    I think they could all be related. What often happens is the maf silently fails, the engine runs lean and then kills the EGT sensors, which puts the car into limp mode. You've also got lambda sensor errors too which wont be helping things.

    It would be useful if you could post up ALL the errors without the shareware stuff so we can see exactly whats going on.

    I'd also reset the codes, have a drive around and see what comes back.

    Hi Aragorn

    Thanks for fast reply m8, sorry about shareware stuff but only got a shareware copy :unsure:
    Anyway those shareware errors are all EGT sensor errors from doing a Google for them.

    I did clear the codes, or at least when I clicked clear it seemed to clear them as I did another scan straight away and nothing cae up, so drove around for a few days then tried again and those codes came up.

    The MAF was replaced 12 moths ago looking at the invoices from the previous owner, is it likely the MAF would fail again in such a short time?
    I have read other posts the MAF does seem to be a little problematic though.

    Scott.

    I just mean post up a list of each code and its proper description.

    If you go onto the rosstech website you'll find a list of all the codes and what they mean.

    Makes it a bit easier to see everything in one list than me having to go out and google each code myself to see whats going on!

    Is the MAF genuine Bosch, if not then thats probably why its died.

    I think you'll probably need at least one, perhaps both EGT sensors depending on what the fault codes say, and possibly even two lambda sensors, as one of the codes there is pointing at a lambda fault. You'll probably also need a new MAF if its not a genuine one, but you could try cleaning it.

    Hi sorry for confusion

    Error codes as follows

    17861 - Exhaust gas temperature sensor 1 open/short to B+

    17865 - Exhaust gas temperature sensor 2 open/short to B+

    16538 - O2 Sensor Circ.,Bank2-Sensor1 No Activity Detected

    17965 - Charge Pressure Contr. Positive Deviation

    18010 - Power Supply (B+) Terminal 30 Low Voltage

    I really don't know if it is a genuine Bosch MAF, how can I tell if it is or not? Would it be buy number printed on it or something else?

    Thanks for your help so far

    Regards Scott

    If you have an oiled air filter that can also kill the MAF prematurely.

    Would suggest you take the car to a specialist (ie: Unit20 or MRC) and get them to take a look at it. From the looks of things it's going to require some painful open wallet surgery.

    Where are you based?

    Looks like it needs both egt sensors and at least one lambda (i'd probably change both for good measure), however the lambda fault says both the heater is broken and the sensor is dead, which might indicate a wiring fault rather than a dead sensor.

    "positive deviation" of the charge pressure control i think means its overboosting, which might indicate a boost leak or a faulty N75 valve, or it might be related to the MAF.

    Sorry Folks

    One more very important question, where is the best place to buy sensors and MAF from?

    Siena on here can get bits for decent prices, otherwise euro car parts and/or the main dealer?

    You should contact Philip Walker who runs PW-Motorsport (site sponsor). He is in Pembrokeshire and knows a hell of a lot about the S4.

    He can probably get you a good price on parts too. I've bought some stuff off him in the past and can't recommend him enough.

    Update*

    Well I went to see Phil at PW Motorsport last week and he said MAF was def gone and looked like F-hose was split so ordered new to try these first.
    Had MAF and F-hose replaced on Saturday and hose had a big split in, that cured the Boost pressure fault, MAF fault also cleared. I just have the EGT and LAmbda probe to do, that's where the money is lol, close on £600 for parts grrrrr, need to save up now for a few weeks and drive like a grandad lol.

    I will update when the work has been done, hopefully I should then feel what an S4 should feel like.

    £600 for two EGT and two lambdas sounds expensive to me...

    egt are about £160 each (maybe he needs 2) and the lambda can be upto £110 iirc

    Lambdas can be had from your local motorfactors for about 30 quid.

    I wouldnt be paying anywhere near £100 for one.

    Fair enough on the EGT's, i reconned about £125 each.

    Yeah EGT x 2 @ £160ish each only place you can buy them (or so Europarts say) is from stealers, and the Lambda probe is aprrox £120 so £440 for parts and Phil gonna charge around £100 for fitting, sorry got me figures mixed up lol.

    Total of approx £540, not too bad I suppose although it was a bit of kick in the ass, wish I knew what I know now about S4 as I would have taken my laptop and VAG-COM when I went to pick the car up, you live and learn I guess.

    What I am looking forward to most is experiencing the full power of the beast, I must be way down on power as after 3rd gear the S4 is no faster than my 2.5TDi 163bhp :sob: I hope to god it should be alot faster or I'm going back to diesel power lol.:wtf:
