    Custom Gauges on RMC/MMI Screen

    Yes I did. Here's a few pics (taken by a bad camera, incompetent photographer, or both :sadlike:)

    Audi S4 B8.5 can’t select ADS and efficiency mode

    The primary purpose of ADS is to control the 3 cost options of dynamic steering, dynamic suspension and sports differential. Of the 3 the latter is of highest value benefit, to the subset of owners whose driving style pushes the standard rear differential beyond its limits. The dynamic...

    Audi S4 B8.5 can’t select ADS and efficiency mode

    ADS was never standard. I have read that if the button is retrofitted it works properly.

    S5 (2014) Mild Vibration / rough idle.

    You'll need a diagnostic scan. Usual symptom of PCV failure is excessive vacuum at the top of the engine - how hard is it to remove the oil filler cap whilst the engine is running?

    S4 B8.5 Electrical issues

    How old is the battery? Seemingly unconnected errors often occur when the voltage gets too low.

    Gearbox / rear diff oil change intervals ??

    I don't know about the manual, but the s-tronic transmission has a 38K miles ATF & filter change schedule. The rear diff is officially sealed for life.

    2013 B8.5 S4 oil consumption issues

    Yours is a 2014 build car? Did it get the CREC engine? If so it appears that the injectors are keeping carbon build-up low and cleaning is not needed.

    B8 S5 - Buying help needed please

    From your other posts I assume this refers to a UK car. A 2012 build should have the 2nd generation 0B5 transmission. It was an improvement over the 1st, but the mere fact that there was a 3rd indicates that there were still problems to be fixed. My advice would be to find out for certain if it...

    2013 B8.5 S4 oil consumption issues

    If it is a bad PCV then the supercharger needs to be removed to replace it. Other items which could be replaced at the same time are the waterpump and thermostat. Both are items that can leak and/or cause problems at higher mileage. Then there's the crank pulley and tensioner. The former has a...

    2013 B8.5 S4 oil consumption issues

    BTW whilst some oil consumption can be considered normal, frequent filling is not. The only time oil goes into my engine is at the annual service.

    2013 B8.5 S4 oil consumption issues

    PCV is the main cause of oil consumption on this engine. When you have topped up, how much effort was it to remove the fill cap? A bad PCV can create quite a vacuum. It is possible to get a dipstick which fits this engine (although there isn't one specifically for it). I don't recall the part...

    Clutch slippage? A5 3L Quattro 218PS B9 2017 Automatic

    Stage 1 should have taken the peak torque from 400Nm to 500Nm. AFAIK the 0CL DSG was rated to 400Nm. Has the TCU tune increased clutch pressure? Nevertheless since the car has done 127K it seems likely that the B clutch is worn. Both will need to be replaced.

    Update on the S4 Recently Purchased

    If you can spare the time, go over to Audizine and read about 0B5 transmission experiences there. There are plenty of reports of problems and a few about the mechatronics repair kit. Maybe you'll get a better idea about how bad yours is and how urgent it is to take action.

    Update on the S4 Recently Purchased

    Is this a 2009-2011 car? The early gearboxes did suffer from mechatronics problems. There is a mechatronic repair kit available. But did I misread something? I thought that your problems were TCU comms and a possible clutchpack slip. Mechatronics is all about gearchanges.

    Update on the S4 Recently Purchased

    As you may have seen there's lots to be found about this gearbox on the web. This is worth reading: https://forums.ross-tech.com/index.php?threads/15276/

    Update on the S4 Recently Purchased

    Whilst the hill start judder does point to clutchpack wear, the P174000 implies an issue with the sensor and/or wiring rather than overheating. The dates of the DTCs are relevant - sometimes they can be old and so not necessarily indicative of a current issue. But at 117K miles with only one ATF...

    B8 Headlight Washer How to Open to clean

    Do you mean the jets which rise out of the "bumper"? If so you can carefully prise the lids and pull them up, but they are spring-loaded. The only other way to access them is to remove the bumper.

    2015 S4 b8.5 74k Miles

    As @ninjag noted, in theory the port injection on the CREx series engine should prevent significant build-up of carbon at the valves. Based on the few photos I have seen of CREx valves compared to the many of the previous engine it appears that this is proving to be the case. PCV failure was a...

    2015 S4 b8.5 74k Miles

    FYI mine's also a 2015 with CREC engine and the car has done almost 26K miles. It uses negligible oil - between annual services the MMI might drop 1 or 2 bars at most.

    2015 S4 b8.5 74k Miles

    Audi engines can burn oil but it should not be considered normal. Have you checked for any signs of oil in the coolant? Any signs of exhaust smoke? Also how easy is it to remove the oil filler cap? If the PCV is malfunctioning then as well as the oil level dropping it can create a vacuum beneath...
