Yeah, will do…I think it will be fine. I looked a little closer at that code and it appears to be directly referring to the Active Exhaust:

I have a feeling that is just a code that can intermittently present when someone is pulling fuse 15. Perhaps that is what intermittently presents as a code when the ECU goes to initiate a GPF regen but then won’t due to the circuit being open because of fuse 15 being pulled?

Anyway, certainly not expecting this to occur again. The ASR makes the car think it still has control over the back valves even though it does not, as we have discussed.

 

TOPDON seems quite confident that they will be able to get me up and running for the GPF functions, and if they can’t they are guaranteeing that I can return it with no issues.

I will say, this is a quality unit in terms of build quality, interface, function, work flow, etc… Very nice.

I would also add that it plays nice and cleanly closes the session with the port, won’t lead to battery drain, etc…I was a bit concerned because this unit has a wireless dongle that plugs into the port. All good.

This is the unit:

Let us know how it goes. Would be a good investment if you can force a regen every 3 months. Although depends on the conditions required i.e. drive above 50mph for 30 mins continious.

 

So your car sounds like a stock 2018 SVR/R when you take the fuse out?

 

I doubt that is truly the case given that some of these newer F-types have a GPF filter integrated in the CATs, but it’s certainly much better than not having the valves open all the time and letting the car open and close them depending on RPM. Having them open all the time makes such a dramatic difference.

I’m hoping to get mine improved further again by only replacing the stock back box exhaust with an aftermarket box from Velocity AP (valvetronic that will use the stock valve actuators). I’m told by some that have it installed that it makes a massive difference without being too over the top, even on these GPF equipped cars. I’m already quite happy with the stock setup as long as the valves are open all the time, so this should bring the bump I’m looking for. It seems like a good path for getting a bit more without messing with CATs, removing GPFs, etc…A few have told me that 200 Cell CATs might not be to my liking and could be over the top, so this could be the best approach on balance without breaking emissions laws etc…

I gather the GPF filter didn’t make it to NA until 2022 some time, so if someone is lucky and has the newest facelifted car without a GPF then keeping the valves open would be quite close to the older cars minus some of the pops and bangs…So, same loudness and tone, just without the CAT killing pops and bangs sorta thing…

To be clear, I no longer pull fuse 15 to achieve the valves being fully open. I have an ASR valve controller installed now in order to more safely achieve the same thing…In case ya missed that from above…

 

Will do. Happy to update this thread with any info that could be helpful for folks. This was an important topic for me, and I’m quite certain it will continue to be for others moving forward as people acquire more of these newer F-type variants and get disappointed with the lower sound volumes, want to address it etc ;-0

As indicated in some of the posts above, I think there is a static version of GPF regeneration that has less pre-conditions etc…

 

Thx. I saw the device above. I have a 22 R. Can you make an audio clip so we can hear? I usually just drive above 3200 rpm like at car week when want more sound. I noticed the super cars did the same thing like F1 race…

 

I don’t really have a way to do this that would be helpful and convey what I’m talking about. Just revving the car when it’s standing still is not capturing it given the soft limiter etc…Not the same…

I would suggest you pull the fuse just once and go for a ride to experience it, and then put the fuse back in. Be warned though, the difference cannot be unheard…lol…It’s not gonna cause any problems doing it the one time pretty much for sure, but it’s up to you and your comfort level…Just a suggestion…

There are enough accounts on here from different people that it should give you certainty that the difference is big. It is a lot different. I literally cannot drive the car without the valves open and enjoy it the same way, but that’s me.

What I like is you get some drama without even driving fast or stepping into it…Which is nice..

 

I came from the Mustang world of endless modifications, so I am relieved that I never felt the need to modify JLR products other than minor visual changes.

It’s strange that I could not find a YouTube video so far with the sound of your modification. I think my sound is perfect but I just want to make sure.☮️

 

Not sure what else to say other than, I wouldn’t be going through all this trouble if there wasn’t a significant difference.

Cheers

 

A definite and immediately noticeable change. No way I'm putting that fuse back in..... unless I order the ASR RX1 device. Being an online purchase has givesln me too much time to talk myself out of it. If this was on Amazon with overnight delivery, I would have purchased it by now.

The poser above, who came from the Mustang, probably thinks the F-Type is too quiet even in its loudest form [stock].

I will probably revisit the ASR purchase after I'm able to confirm/deny my ability to run the static GPF regeneration.

 

I got the more expensive ASR module with the auto stop/start function as well.

Good news, full control from the exhaust button rather than a fob. Bad news, the auto stop/start functionality only worked about 75% of the time.

I never want to use auto stop/start anyway, so I just unplugged the module in the trunk. Now, I am getting a service notice at startup, but I also have a half dozen other items unplugged temporarily, and the car just went over 5k miles, so could be related to those as well.

For those who have unplugged the auto stop/start, did you get a notification on the dash at all?

Also, the 200 cell downpipes showed up today. Resonated, so hoping minimal drone...

 

ASR is supposed to have pretty good support. Perhaps ask them. That was a lot more money to spend to not have that work. That would have been the only reason I would have paid the extra (to keep the auto start stop disabled cleanly). In my view that is essentially the only advantage of the more expensive one if you have Homelink buttons to program the cheaper unit to in order to avoid needing the dongles (like I’ve done).

Perhaps the wiring harness splice connection you had to do with that unit isn’t done quite right or something and you are having intermittent issues or something? That was the aspect of that unit I couldn’t do…Just didn’t want to get into splicing the wiring harness of the car.

 

I will say ASR shipped immediately, and it arrived here to Canada within a few days.

 

Have you ever seen a P2169-13 code like I posted above? Perhaps I did because I used to go between fuse 15 being in and out with the Claws Out setup vs. you consistently having the fuse out, and/or because I’ve driven a few more thousand Km than you.

 

If you google that “Exhaust Pressure Regulator Vent Solenoid” description associated with that P2169-13 code I posted about above, it certainly seems to be referring to this other solenoid in the engine bay that Busby was talking about. Perhaps I got lucky and did pick up this code relating to the conditions that play out in the lead up to it’s eventual failure?

I didn’t do too many Kms before rectifying with the ASR so I’m not overly concerned, but this is interesting I’d say…

I would suggest that this MIGHT be the best evidence we have that there could be something to that eventual failure of the other solenoid Busby was talking about? Hard to say for sure, but maybe, and perhaps it takes some time to show up in the codes as you drive more Kms.

Up to this point I was only really fully convinced of the GPF regen cycles getting interrupted aspect of pulling fuse 15, but I’m starting to come around to the idea that there might be something to this failure of the other solenoid now?

I don’t know, I’m just glad to not be having fuse 15 pulled any more just in case. The ASR module definitely seems like an advisable solution to me for anyone wanting their valves open all the time at this point…

 

I'm late to this conversation -- But isn't this a European issue only?

 

No, some time in 2022 even North American bound cars ended up getting equipped with GPF. Wasn’t required in NA, but I guess it was a business streamlining opportunity for Jaguar…i.e.: Not have to differentiate for different markets on the production line etc…

 

I believe it was also done on all cars as a part of a greater conscious effort on the part of Jaguar to quiet the cars down a bit too, which it certainly helped to do…

 

Info for those interested...

I've been driving around over the last few days consciously enabling/disabling the ASR valve controller...Been running a few checks for codes using my iCarsoft LR v3 scan tool after drives and it has been crickets on the error code front. No P2169-13 code or anything else, so again, I fully suspect that was from my pre-ASR days using the Claws Out fuse 15 pulling business...

Cheers
