    DIY S4 Waterpump and Thermostat Install + Supercharger Removed (Pics)

    Guest-only advertisement. Register or Log In now!
    The original early production S4 3.0TFSI Engines were delivered from the factory with plastic waterpumps. They have this tendency to fail after a while and the Audi have rectified this with a superceeded original upgrade part that is now a fully aluminum pump housing.

    have driven the car very hard at times and my original plastic pump/thermostat assembly has not failed to date (>10,000km). So this "upgrade" is purely a preventative measure on my part.

    All the 3.0TFSI engines rolling off the factory plant now use the new part, so if you have ordered a S4/S5sportback or other car equipped with a 3.0TFSI engine not arrived yet. You will be getting the new full aluminum pump.

    Here are some pictures of a DIY install of the upgraded water pump. At the same time the Singapore cars will also get a thermostat change also (tho the part number is exactly the same as the old one, no superceeded part). The factory protocol does not mandate that the thermostat be changed but the dealer here in Singapore has decided to take an extra step up and package the upgrade with both parts just to be on the safe side.

    One take home message here is that for genuine original parts, good to see that there is a continual improvement and rectification of problem issues. I am delighted to see that any such improvement are carried down to serial production also.

    Singapore dealer will take 2 days to do this upgrade for you. I strongly suggest you do not try this at home unless you have al the special tools, torque wrenches and knowhow to do the job. It can be real tricky at times as one connecting pipe is not easy to mobilize at all!

    The supercharger also needs to be removed to access the thermostat housing.

    here are the pictures of the job.......... hardcore DIY guys can try


























    OLD VS NEW WATERPUMPS

    deck, is there a way to see from under the hood wether we have the plastic, or the aluminum? or do you need to remove lots to even inspect?

    did you notice carbon in the intake, or is the car running mostly clean...unlike the rs4's.

    Deck, once again you rule!

    Lou, you should be able to clearly see the pump from the hood, it's got a pulley on it seperate of the SC system, and the black housing is visible

    I echo Lou, were you able to see any signs of carbon?

    Anyone know if the dealer will replace this for you as a preventative measure or do you have to wait until it fails? I don't know which one I have but I got my car around April 2010 (not an in-stock car).

    There are rumors of a TSB for this, though until one happens, doubtful the dealer will do it.

    thanks Lou, yes, very easy to spot the old plastic waterpump - it is black....so you will see a black edge where it mounts into the V6.
    the new ones are all metal, u cant miss it. just pull off the front plastic cover that says "V6 3.0TFI" and you should be able to see it.

    No signs of carbon at 12,000km. to see inside the intake runner flap (closed position). you have to open it.
    do not force it open [danger of damage], what you need to do is put a vacuum tester to the actuator that opens these flaps, once u apply the vacuum the flap will open and you can then use a torch and look down the intake runner to the intake valve.

    what i must also let you guys know is that i specificall run 98RON only and nothing less, the gas used is "CALTEX Platinum" only with that techron cleaning agent that is advertised heavily here in Singapore by fuel company.

    No TSB here locally, the dealer just does it to keep the S4 owners happy cos after the 1st few cars coming in, they decided to replace all the old waterpumps to prevent complaints since the S4 here is priced like the GDP of a small african nation after taxes.

    sweet. no carbon! Looks like it would be fairly easy to pop the charger after 30,000 and do an inspection. Time to go check my pump.

    remove completely the intake pipe (+one vacuum line to intake pipe) from the airbox. then unplug all the mess of connectors on the back of the S/C. there are quite a few, 3 for the solenoids, one for the throttle body, one for the bypass flap, one for the charge air pressure sensor. you will especially find that the connector for the bypass flap cannot be slid out easily as its blocked by the metal plate holding the 3 solenoids...so what i did was to dismantle the entire plate and go grind a small notch on it so that infuture the bypass flap connector can be easily slid out without taking out the 3 screws that hold the black metal plate with the 3 side-by-side solenoids.



    then disconnect the bunch of vacuum hoses also. then the SC is ready to come out. you will need 2 people - one of each side to lift the charger straight out.

    the 6 nuts are 20nm when you put the SC back into the car. observe diagonal tightening rules.

    Great info again Deck. Due to DI, do you really think that Techron helps all that much since there is no way for it to wash the intake valves though? Granted I agree that using the best fuel possible is always a boon.

    IMHO, the techron does not really help (maybe mentally LOL!)....cos the engine is DI in the 1st place so no fuel ever hits the intake valves.
    but so far so good. have another 2.0TFSI at 50,000km and the valves look fine too. must qualify that my engine gets fed new Audi only original oil every 5000km (3106miles)

    i think its all about the blow by scavenging of the crankcase breathing system, the RS4 has the most sophisticated one with triple vortices.
    the TTRS inline 5 is pretty sophisticated also and our S4 system is also not a pushover.
    Audi use a contractor called PolySwirl (TM) for the fine oil separators that utilize the cyclone principal

    If the RS is the most sophisticated, why does it have all the CB issues?

    Good question! I know more than a few 50,000+km RS4s here. No issues except for the vacuum line on some. But that was a TSB issued on that.

    Remains to be seen if the inline5 of the ttrs will have the same or will the polyswirl do its job???

    correctly if im wrong, but isnt the 3.0t running hotter than the TTRS and b7 RS4?

    benz is doing this with their direct injection vehicles also......

    Not sure about the TTRS, but it's set about 10 degrees F hotter than previous models yes.

    Great post Deck Surgeon.

    I have a couple of Noob questions.
    1. Why is the outlet side of the supercharger brown in color?
    2. What does the hotter running engine mean for carbon buildup?

    Thanks.

    Is there a way to determine based on build date without opening the engine cover? Mine is a 2010 with a Feb build date (I'll double check again)

    Thanks.
    1. The PCV valve (Positive Crankcase Ventilation) recirculates unburned exhaust gasses back into the supercharger for entry into the intake to for reburning - this is an EPA mandate from Waaaay back when, my 1968 Mustang had a PCV valve. Hence the green text on the same pic you refer to, which shows the dump valve for large oil particulates which are recirculated into the SC drop out of the air and pool in the bottom of the SC, to be scavenged by the oil recovery system.

    2. Since DI (Direct Injection) engines shoot the fuel straight into the cylinders instead of across the top of the intake valves, fuel doesn't wash these valves to clean off deposits of the above mentioned unburned exhaust gasses. Over time these harden and disrupt airflow or even the proper seating and seal of the intake valves. Increasing the engine temp allows these valves to get a little hotter than previous models, which (in theory accordin to Audi) should be enough heat to bake these deposits off before they can harden there.

    Why not pop it off? It removes in less than a second and sits on there like a tupperware top - just pops off and on.

    NWS4Guy, thanks for the explanation.

    I have heard before that synthetic oil "ashes" as opposed to "cokes." Is that not true or does that not apply when it is not in solution?

    I have not heard of this, but if you can find evidence this is true, it might be a large part in deciding what type oil to use (I personally prefer synthetic anyway).

Increasing the engine temp allows these valves to get a little hotter than previous models, which (in theory accordin to Audi) should be enough heat to bake these deposits off before they can harden there.



    Why not pop it off? It removes in less than a second and sits on there like a tupperware top - just pops off and on.
    The PCV redirects to the cylinders the evaporation fumes of oil from the crank not exhaust anything lol

    Yes, was thinking about EGR when I was typing PCV, thanks for catching that!
