    PCV valve replacement - other things to check (upgrade?)

    This is a copy/paste of your post about this from last year (09/10/20)........ OK mechanic confirmed it's the bypass pipe that's leaking, not the thermostat housing I repeat, "Are you certain the Thermostat was replaced?"

    PCV valve replacement - other things to check (upgrade?)

    Thermostats don't normally leak (that's the waterpump), they start to stick (closed) and cause the engine to overheat/fans running all the time. Are you certain the Thermostat was replaced? For the extra cost of replacing the PCV Valve, whilst the supercharger was off last year, I would have...

    PCV valve replacement - other things to check (upgrade?)

    Just be careful, there are internal (pressure) differences between B8 & B8.5 PCV Valve. Usually, it is highly recommended to replace the Waterpump and Thermostat whilst the supercharger is off. Definitely replace the Thermostat IMO. The plastic coolant "crossover" pipes can become brittle with...

    Low oil pressure S4 b8.5

    @ninjag you are correct! In your pictures above, the top two are from a B8 and the lower one is from a B8.5 - very different seals. I do apologise, I am mistaken, the CAKA & CREC engines have diferent oil filters! In my defence the mann catalogue lists both engines, however when you go further...

    SD Card What Is The Biggest I Can Use

    My 2010 B8 with basic Concert works fine with a SAMSUNG EVO 32GB microSD HC Card in an adapter. I believe it was only the very first B8's 2008/2009 that were limited to 4GB SD Cards. Be aware that most of the "cheap" cards on ebay and amazon are fakes. There is a test you can run to check...

    PCV valve woes

    @HertS3 Just for your info. the PCV valve is a mechanical oil seperator and it has no electrical connection. It is made from plastic and has oil vapour (crankcase ventilation) and water running through it (seperately) which can lead to leaks either way or out of the unit, if it cracks. The main...

    New battery, is coding required?

    The car should "learn" it's got a new battery fitted as you drive and re-enable the shutdown circuits.

    ESC fault

    I belive all three "faults" circuits are linked to it, ESC Stop/Start & Cruise control. Also, when water gets in to the ECU box (usually due to blocked scuttle drain) it can not get out again, so leads to codensation/damp which can play havoc with ECU PCB. The capilliary action should only have...
