    A3 8v Brake Pad Sensors

    Wow, really? It borders on disappointing that a disrespectful attitude still exists when an input or opinion does not align with your's. It really is a disincentive for others to contribute to this forum, or even to ask questions. The fact is no one except the engineers at VAG knows why the RS3...

    A3 8v Brake Pad Sensors

    Possibly because the RS3 being the highest performance variant and likely to see some track use, Audi had decided that the "count the rear caliper motor revolutions" to be not sufficiently accurate to detect pad wear before disc damage occurs? For example, if the rear pads have 20% pad...

    A3 8v Brake Pad Sensors

    Yes, you are right. Should be the "A3/S3 8V platform" not having wear sensors. It appears only the RS3 have the wear sensor on the rear left caliper per the service manual:

    A3 8v Brake Pad Sensors

    T-1000, looks like you have the S3 or RS3 based on the ventilated rear discs. Seems like Audi has included the wired wear sensors for the rear pads on the S3, but it's absent on the A3 models. Or it might have been a running change from PFL to FL. Mine is a PFL so never seen a rear wear sensor.

    A3 8v Brake Pad Sensors

    No, there aren't the traditional wired sensor for the rear pads on the 8V platform. The rear calipers are electronic actuated, and part of the process of pad renewal is to use VCDS to reset the calipers to account for the thickness of the new pads. This means the ABS module knows the starting...

    2015 Audi S3 Smashed - xfer engine into A3?

    Sorry to hear about your situation. My take on the options: Option 1: Repair the damage - it looks like you will find quite significant structural damage. It is not just a matter of swapping out damaged doors, skirts and airbags. The high tensile steel structure where the B pillar is would have...

    Facelift S3 low coolant

    The water pump and thermostat housing is buried right at the front of the engine block. In your photo, immediate to the left of the yellow circle with the word "Lots", you will see the aluminium body of the throttle actuator. If you peek down below the actuator towards the engine block with a...

    1.8 TFSI

    I have a 2014 1.8 TFSI Quattro in a saloon. Day to day driving the engine is great, torquey at the low and mid range. It's only when you are really pushing it that it falls off power at higher rpms. This is due to the small IS12 turbo, which spools quickly and runs out of puff quickly too. My...

    Can steering rack replacement coding cause T23 code?

    You mentioned it was purchased CPO, would it be possible the car was tuned before you purchased it and it wasn't caught by the CPO inspection?

    Creaking noise at rear of the car when turning sharp left

    I had the same noise from my A3 saloon, rear left area. I thought it was the side pillar trims initially, and spent a lot of time and energy trying to get rid of the noise. I finally isolated the sound to the rear left door latch. If you close the left rear door to the first latch position...

    1.8 Quattro 177bhp remap review??

    The 1.8T is paired with the IS12 turbo, which is the smallest of the turbo options on the EA888 Gen 3 engines. A Stage 1 remap will improve torque and hp to an extent, but you will not be getting the top end power the S3 will have with the IS38 turbo. That being said, the IS12 is quick to spool...

    Air Con problem Hot Air

    Definitely avoid the stop-leak, it will not fix a hole in the condenser. If you flood your system with stop-leak, no air conditioner service shop will work on your car anymore as the stop-leak clogs up their recovery machines. Costs a fortune to clean up, if you get asked and you don't tell...

    My A3 8V TFSI ran 198bhp??

    APR publishes dyno results for the 1.8 coupled with an IS20 turbo on their website. https://www.goapr.com/products/turbo_18t_g3_is20_mqb.html Their max power is achieved with IS20, APR downpipe and 104 octane fuel, producing 319 hp at the crank.

    My A3 8V TFSI ran 198bhp??

    Yes the IS38 is a direct bolt on for the 1.8 EA888 Gen 3, but do consider that while it can make significant power and torque at higher up the rev range, lower rpm response do suffer. It is sized for a 2 liter engine which has higher volumetric flow than a 1.8, so it will be laggier on the 1.8...

    ⚠️ALL S3 8V OWNERS COOLANT LEAK!!!!!!

    Lehn, Those wet greasy spots on the undertray and the position of the residue on the plastic oil pan was exactly the symptoms I had in mine. I confirmed the leak on the thermostat housing, which seems to happen only on longer drives on warm days, probably early stages. I ordered the parts from...

    1.4ftsi COD noise saga continues....

    How about you scan the used car classifieds in your area, locate a similar year PFL A3 with the same COD engine and ask for a test drive? You can test a few and come to the conclusion if the noise is indeed normal or not. If none of the cars make the same noise, then you are in a stronger...

    Wing mirror replacement help

    Also be careful about buying from European ebay sellers, as their cars are predominantly left hand drive which means the mirror you need is actually their passenger side mirror. I suspect the actual shell and mirror angle is different, so something to look out for too.

    B&O Retrofit or new car... :(

    The money invested to install B&O into your car will never be recovered when selling or trading in. If you are planning to keep your car for many years, it may bring you some personal satisfaction during your ownership. If you want better sound without dropping 3000 quid in, investigate...

    Does anyones else car do this?

    Sorry Audi Ashley, but I can hear more of your breathing in the video than the COD noise, which suggests the noise you are referring to is very soft. Some noise is acceptable from any internal combustion engine in normal operation, we can't expect the engine to make zero noise. Turbocharged...

    Upgraded Turbo A3 1.8TFSI

    The general consensus is the IS20 will be better for daily drivability, with just a bit more lag than the original IS12 but improved mid range and top end power. The IS38 will be slower to spool up than the IS20, but will give you the most top end power. Don't forget, both IS20 and IS38 are...
