    Rear Oxygen Sensor

    So the sensor was swapped out and other than the light is now off there is no difference in how the car drives. While the car was getting fixed I had a loaner 1.0T and other than feeling a bit crisper with the clutch (newer car) it felt the same. Suspect I need a remap...

    Tyre Management System

    Yeah, just had a look in the manual and it confirms. Not sure how much of a bodge it is - on previous cars the same type of system has told me of pressure loss that I wouldn't have spotted with a visual inspection. But its probably not as precise as the direct sensors. However I guess there is less to go wrong which isn't a bad thing.

    Tyre Management System

    Hi - no I haven't taken the wheels off but I'm confident its an indirect system because there is the function to reset the system (which you have to do once you have corrected the low pressure warning / put new tyres or wheels on the car as instructed in the manual). This would not be relevant to a direct system. Second, and more telling, when I put my winter wheels on from my old car (the previous generation S4) the system did not not get upset I had installed wheels without sensors in them.

    Tyre Management System

    As said before I'm not sure whether the new legislation mandates pressure sensors in the wheels. I also have a 2017 Audi S4 (the entire platform was new in 2015 - so would be a 'new type) and that uses ABS sensor data to work out whats going on - as far as I'm aware that is the case for the vast majority of VAG cars. All the VAG cars I've had since 2005 have had this form of monitoring. Whilst VAG are known to take a loose approach to complying with legislation I doubt they would get away with this if indeed it is mandated that the technology used is direct pressure sensing in the wheels. In the US things might be different - and I wonder whether thats why the American manufacturers use this system because they want to standardise technology across all markets. Whereas European manufacturers take a different approach (lowest cost technology they can get away with in each market). I have to say in my experience the ABS systems do work, and are less of a PITA with respect to changing wheels with no additional parts to go wrong.

    Rear Oxygen Sensor

    I took delivery of my new to me 2014 mk 3.5 1.0T focus (125) at the end of December. A week ago the engine management warning light came on saying and the garage says it needs a new post cat oxygen sensor. The car drives absolutely no differently to how it did before, and over the last couple of tankfuls on my commute its return a healthy 45 mpg. So far so good. I have a wee bit of a doubt though, I've heard this engine described as 'lively, rev happy' and so on - but I'm not sure I would agree with that. Bury the throttle and it gets round the rev counter but feels like you are eeking it out. It does seem to get a second wind at about 5k rpm. Obviously there is a known fault at the moment, but I always thought that rear oxygen sensors didn't really affect performance as such and were there only to monitor the health of the cat. So wouldn't expect it to really affect anything. Its not limited to any revs (limp mode) as far as I can tell. Are you supposed to hear a whistle or hiss - indications that it does actually have a turbo? I can't hear anything. Like I say, it was like this before the light came on - and we'll see soon enough if a new o2 sensor helps. But wondering if there is something else amiss as well.

    TPMS - Disable

    Not true, as far as I'm aware most VAG cars use the ABS sensors. My 2017 S4 doesn't have sensors in the wheels. I don't think the legislation mandates the technology used, just that some form of it has to be used. I guess each has its pro's and con's - but not using this sensors in the wheels sure makes changing wheels a lot easier!

    TPMS - Disable

    Yes I agree - The golf I traded in had Michelin Crossclimates on it for that reason (and very good they were too). But since the 'new' car came with Michelin Primacy's with quite a lot of tread left I didn't want to bin them to replace with crossclimates just yet. So I got a set of winter wheels tyres. By next winter I'll have cross climates all round and had I realized Fords have these stupid sensors in the wheels I might have taken a different course. Ah well.... My other car keeps separate winter summer / tyres - all seasons are very good but don't rival the performance of a true summer tyre.

    TPMS - Disable

    I don't think those examples are analogous - since TPMS does not directly affect the cars safety in the same way that a broken bulb or ineffective tyres does. (Cheap does not always = bad). Its interesting to note that the primary driver for mandating TPMS in Europe was not safety but rather to reduce CO2 emissions caused by under-inflated tyres). How many people who have remapped their vehicles, taking it outside the original emissions bracket have had their vehicles re assessed to see if they owe more tax? I'm sure the tax man could make a case for tax evasion should they ever take the notion. I prefer to balance cost, benefit and risk and make my own decisions from there.

    TPMS - Disable

    I bought the wheels with tyres from gumtree before I took delivery, Had I known about this I would have done something more pro-active... My 2017 Audi S4 doesn't use individual sensors in the wheel and had no complaints when I swapped wheels so I didn't expect this to be a problem. I'm interested in the screw on sensors - will have a look for those. Thanks for the heads up that DDS isn't an option on the 3.5's - I won't bother attempting to get that to work!

    TPMS - Disable

    Hi, thanks and noted. I have effectively disabled the system by removing the wheels with sensors. The car is significantly safer with winter tyres (minus sensors) rather than summer tyres (with sensors). What I'm looking to do is change the system from the sensor based approach to the ABS sensor / rotational speed system known as DDS (deflation detection system). If thats not possible I want to remove the warning by turning the system off - which in itself is not disabling the system any further than it already is. More than anything I'm looking for any advice on the coding side of things, i'm getting somewhere with forscan but currently in the process of downloading a bunch of calibration files.

    TPMS - Disable

    Hello, My first post... I've just taken delivery of a 2014 facelift focus 1.0T Titanium X. I've swapped over the standard wheels for some steel wheels with winter tyres, and the TPMS system does not like this. I was unaware that Ford uses sensors in the wheels.... I have an ELM OBD cable, and focccus / Forscan but am at a loss how to recode the car so it thinks its got the DDS system (using ABS sensors only) or to completely disable the system. With focccus I can read the BCM data, and it looks like I can change the TPMS system in the menu to DDS, but I get many errors when I try and write the file back. Plus the car goes batshit crazy. Cant' seem to see a way to try this with Forscan which at least seems to be quite stable in comparison.
