O/T I did try to get the R8 paddles for my RS4, anyone know if all Audi paddles fit all cars?

Don't quote me on it but I don't think so. I think most fit most but some don't.

On a side note - if you don't want to spend £150 on the carbon ones. This guy on youtube bought these ones - here and done a video on them here. They're metal and sound like good quality in his video - £60.

Re the buttons - do these need coding and are a plug and play fit?

Plug and play.

They have a loom that takes power etc from the existing wiring.

They work on a Bluetooth transmitter that is fitted in the centre console where the start button is.

Here’s a link to them in action.

So had my car back a couple days now so can give a bit of a review of the decat and the OPFs removed.

First thing is unfortunately the bypass valve didn’t work as the light shows back up, this happened at the company and they offered me the option to put it back to standard but I choose to leave it be for the moment as a light on the dash doesn’t outweigh the positives of this. Basically the bypass worked on the 8V through the OBD port but on the new 8Y platform the OBD port is only active/in operation if the bonnet is open, essentially in a maintenance mode. Infinit performance is working on a fix for this with the maker of the bypass valve so hopefully have something sorted in the upcoming months. The car drives perfect, it was logged for 300 miles and doesn’t over-boost or over fuel, it doesn’t enter limp mode. Drives as it should, just a SH17 tonne louder!

I don’t know how but it is louder than my stage II facelift Pre-OPF was! This absolutely screams and sounds phenomenal! I’ve purschase a new go pro so as soon as I can I’ll get some driving videos for you, valve closed/open videos and also so 0-60/100/200 times ect for use.

It was far to loud with the PCW mod so all that has been reverted back to stock, no wastegate rattle as I mentioned before. Valves work as they should do in comfort mode up to 4000 revs the car is the tiniest bit louder than stock, but it dynamic or performance mode, I want to say it, sounds like a lambo! There is no pops or bangs as the before generation. It has very loud upshift snaps, and also when I do let off the accelerator I hear the slightest burbles like it used to do, they are very faint but they are there and it’s like it’s trying to do them. I’m not sure if you could hear these from outside or if the GoPro would pick them up but they are there!

So Is it worth it and would I do it again even if I knew the light would come back on? Yes 1000% I would. And I’m sure @Aoon_M will come up for a solution for the fix.

Nice one Billy - good that someone has removed the OPFs and Cats and is happy. As you say it wont be long before @Aoon_M comes up with the EML fix, and also break in to the ECU for further tuning upgrades :)

That's a bit of a bummer about the EML coming back on but hopefully they'll have a work around soon. It would bother me too much so that's off the cars until the ECU is cracked or the bypass is sorted. Good that the car hasn't over fueled etc with it on though. I'd just be happy with pre-OPF FL levels of volume tbh.

When you say the bypass valve, is that relating to the cat or the OPFs?

If it's relating to the cat, I'd assume that a sports cat would sort that and you could still run it without the OPFs. If it's related to the OPFs then that's a little more of a pain and I imagine will need some work or a remap down the road.

It’s both, sports cat won’t help unfortunately

That's a shame. I wonder if R44 could help as they do a bunch of modules for BMWs? Obviously if they work the same way through the OBD then probably not, but maybe their OPF defeat devices are stand alone.

He’s going to speak to the people who do there’s and see if they have solution but like you said, theirs work the same way

Fair enough, it makes sense.

I do wonder if someone with a bit of an electronics/software background could just create something that draws power off the original plugs and just links the upstream and downstream sensors and generates a signal that the car sees as the OPFs being something like 90-99% operational? That wouldn't need interaction with the OBD port, but imagine there's a reason they haven't done that yet.

I think the ecu software is a bit cleverer than that from what I saw regarding something as simple as an adblue sensor on an Audi.

The OPF sensors/ecu will want to see the differential pressure rise and then reduce as it cleans them, if they stay clean forever it will most probably know something is wrong, with each new version this type of emission stuff gets more and more sophisticated

It's possible, but there must be cases where folk drive OPF vehicles on long trips all the time and they don't need cleaning by the car specifically? I doubt it'll flag up an error as a result of something working too well, surely? It's a reasonable point, I just don't know how they could possibly implement it and what the point would be apart from specifically targeting something like this.

The ecu can monitor just about anything with all kinds of algorithims working away in the background, it will know that the car is always on the Motorway etc and could be able to predict when the filter needs a clean and if the pressure sensors say all is ok when the ecu knows it shouldnt be it will flag it

Adblue even has ultrasonc or radar tank level measuring, it knows whether it's adblue (pig ****) or water, it knows how much to inject and what the corresponding exhaust temperature should be and how much should be getting used depending on your driving, it can and will also stop you driving the car if its faulty.............it's getting clever out there :openmouth:

It’s probably measuring the pressure differential across the OPF’s when they are fitted, the software probably knows when a steady reading happens for too long that somethings amiss.

I agree it’s all possible, but I wonder if things have changed in regards to this intelligence since the last generation of OPF defeat devices that plugged into the OBD and worked. The only difference so far is that they can’t use the OBD, so being optimistic I’d hope they haven’t changed the monitoring scripts in the background as well. Who knows until folk crack the ECU.
