    A4 TDI exhaust rust question

    I went along to the easiest VAG dealership to buy one for my wife's VW Polo 1.2TSI 110PS, which was a Skoda dealership, they had none in stock, and on back order at the UK warehouse, this was said to be due to change/revision of that part, so maybe it is finally getting made to survive as long...

    Charge Cooler Pump Operation B8 S4

    I think that I have answered my question, there is a one way valve built into the only link this section has with the small return pipe to the coolant reservoir.

    Any Aircon Gurus??

    It would be "Bar" that VCDS was reporting as a pressure reading, 1.0Bar = 14.5psi I checked my wife's 2015 VW Polo 1.2TSI hours after it had been recharged by ATS and with an ambient temperature of 23C, with the AC demanding maximum cooling on an auto AC system and the engine at 1000rpm, VCDS...

    Charge Cooler Pump Operation B8 S4

    No, it is charge cooler pump I am meaning, my car is a 2011 B8 S4, and the option for coolant pump does nothing in VCDS - which was obvious when I then looked further down the output tests list and found charge cooler pump. My car has a mechanical coolant pump but I initially expected that the...

    Any Aircon Gurus??

    Have you checked and noted down the pressure using VCDS, does the front mounted cooling fan run when you demand cooling, if the fridge gas charge is low, but enough to keep the system working/happy, then the pressure shown in VCDS when you demand Lo should tell you something, maybe check that...

    Bump Bump! No knowledgeable B8 S4 owners out there?

    Charge Cooler Pump Operation B8 S4

    Can anyone tell me if there should be evidence of coolant circulation - ie coolant passing out of the small return pipe into the coolant reservoir, when the pump is activated using VCDS and the engine is cold? I have been checking this prior to replacing the coolant so that I know if/when that...

    Coolant replacement B8 S4.

    Well the general web chatter on this subject seems to suggest that 8 litres is a close enough guess. The current price for G12EVO premixed to 50% is £7.13 inc VAT from VW and VW Van Centres, so that knocked any online suppliers out of the game when delivery was taken into the equation, even...

    Coolant replacement B8 S4.

    Sorry if I've missed this question being asked in the past, but, does anyone know what the coolant system capacity is for a 2011 B8 S4 6MT?

    Coolant replacement B8 S4.

    I meant to write "G12EVO conc" not "G13EVO conc" ! My mistake!

    Indicator bulb type.

    Well 1 year and 2 months later, and I have finally got round to removing a headlight to check which type of indicator bulb is correct for my 2011 B8 S4. Having smallish hands did not stop uttering lots of bad words though. The bulb is definitely the version that has an inline socket on the back...

    Coolant replacement B8 S4.

    @spartacus68 , quote "I mean you're at 26k on a 10 year old car." - yes, maybe I should be sectioned! For knocking around locally, I really don't like using my S4, the worry that naughty people might mark it and only getting 28MPG, when my wife's 2015 Polo 1.2TSI 110PS is excellent for that...

    Coolant replacement B8 S4.

    As per the thread title, I had been considering replacing the coolant in my February 2011 B8 S4 mileage is low, 26K! Anyway, I have been testing the ph level at every service using coolant test strips and checking the freezing point using the same strips and a refractometer. It still seems to...

    Front end whine...

    Are you sure that the AC compressor has a clutch, I don't think they have, in fact I'm 99.9% that all AC compressors at least from B8 onwards have constant driven compressors that have their delivery regulated by being variable displacement.

    A4 B6 1.9tdi 130 AC issues

    Well, maybe some things to consider, did you use a general tyre/exhaust etc place to recharge the system, or a proper AC place? If it was the former, they would not have enough knowledge normally to monitor the system while it was operating, just qualified to handle fridge gas and operate a...

    Steering wheel not central

    If the car drives straight ahead without wandering when the steering wheel is in that off-centre position, then it should only require the steering rods adjusting, one side in a bit and the other side out a bit.

    Car cover A4/S4 - Recommendations

    No, you missed the point, Sandra is a site admin person, though I can't see any reason why the name of what a member thinks is a good brand/make should be hidden just because they ended up being a past sponsor. This forum runs for the members not that site admin, without members it is nothing.

    Front Parking Sensor "Always On"

    I can't say, I retro fitted them to my 2011 S4 so the bumper needed taking off. The plastic retainer clips are quite strong probably even in summer weather, you can but try to get in from below after removing the lower screw fixings and the under covers. Taking the front bumper cover off is...

    Front Parking Sensor "Always On"

    Just make sure that you buy the "inline" connector version, there are many discontinued/superseded part numbers that are equivalent to what is fitted to your car, the rear sensors are "right angled" - well that is for B8 models. Edit:- always remember that it could just be a wiring issue with a...
