Can it reset the Service Now light?

 

From what I have read, no, not yet. But they often update the software, it seems.
I just bought an NT520, should be arriving soon, so I will know for sure at that point.

 

 

Please let me know if it is able to.

 

I will update, but it looks like the answer will certainly be no.

I bought two of these (Foxwell NT520 Pro), one for my X5 and one for the Cayenne. I know I could put both cars on the same unit, but wanted it this way.

Anyway the BMW one arrived today (Porsche one on its way), when logging in, registering, checking for SW updates, etc. on foxwelltech.com, I see that Porsche has not been updated since Sept 4, 2018. I think people have reported after that date that reset is still not available. On the better side, Sept 2018 is one of the older SW versions they have up there, so maybe an update will be coming soon. But if you really care about the service reset and want it soon, I'd look elsewhere.

Looking at the change log on that 9/4/2018 release, there is only one thing listed: "Modify not support Oil Reset problem on Porsche Boxster 987."

And BTW, I basically picked the Foxwell because it is highly regarded for BMWs. And I hate research projects when I can avoid them. So if I can get something for the BMW and not have to learn something completely different for my Porsche, I'll do it - and the Foxwell seems reported to work pretty well on the Cayennes, with extra programming functionality for the 955 (vs the 957 or 958). Got a good deal too, buying two at once for about $120 each.

 

I bought the Foxwell NT520 Pro for my 2005 955, I haven't used it yet but this is a description from the manufacturer of what it will do:-

- Full System Coverage

- Electronic Parking Brake Reset (EPB)

- Oil Service Reset (OLS)

- DPF Regeneration (DPF)

- Throttle Body Alignment (TBA/TPS)

- Battery Configuration (BRT)

- Stand-alone Operation - No Laptop or Batteries required

- Extremely easy to use

- Comprehensive help - including DTC Library Database

- Multi-Lingual Menu and DTC Definitions

It does mention oil service reset so I assumed it would be able to do it!

 

Well if you're just going to take their word for it, you could just stop reading at the first bullet item there. Full. System. Coverage. Boom.

I think that list is generic for all versions (car manufacturers) for the NT520 Pro. Some of this is complicated stuff, with differences for each manufacturer, and some are up to date / fully implemented, some not.

As I quoted above, their most recent Porsche SW update added the oil reset for the Boxster. Also, I don't know details yet, but is there a difference between different messages like Service Now, Oil ???, etc.? I think mine says Service Now. So when my unit arrives (due Monday), I'll be able to see if it does it, and I'll make careful note for the exact message I have. I don't expect reset of that message to work, but will certainly try.

Since it is listed as a feature, I DO expect service reset to work one day, hopefully in next year's update (guessing that's how often they update, based on looking at other SW version dates). If you don't yet have that warning to reset, hopefully the SW will update by the time you need it.

The airbag light has been on for years now (before I bought the car), so that will be one thing I fully expect it to fix.

Also, it seems that documentation accuracy is not Foxwell's strong suit. They list Porche (vs. Porsche) in many places - check the box your NT520 came in.

When yours came, was the Porsche SW pre-installed or did you need to first download it from foxwelltech.com? My BMW unit was pre-installed, even with the latest SW version from January. But then, the BMW check-box on the cardboard box it came in was checked, vs. there is not even a Porsche check-box on the box. So maybe they don't sell Porsche as pre-installed.

 

The software for Porsche was pre-installed by the seller but I think he downloaded it from Foxwell and installed it before shipping it to me, how good it is will be apparent only after I've used it in anger, please keep the thread updated with your experience's of using it as well please.

 

LOL will do. So true about the difference between using something when it's not important vs. necessary.

 

My Foxwell NT520 Pro arrived yesterday. Tested out just now ...

Short answer is - News flash ... don't believe everything you read on the interwebs. "Service Now" (oil maintenance interval) was successfully reset using this tool.

Problems I knew I had going in: airbag light on (for many years), Service Now message. My expectations of success/failure were wrong on both items, so don't ask me for my March Madness bracket picks. Not good at predicting things, it seems.

Hooked it up. It was unable to read the VIN (unlike on my X5, where my other new NT520 Pro had no problems), so I entered it manually.

In the Porsche SW (vs. the standard OBDII functionality), it found almost a dozen total error codes, which I logged and reset. I successfully cleared all but the:

Airbag - 3 - Control Module Faulty
and
Air Conditioning - 1592 - Air quality sensor
I don't know of any actual issues with my AC. In going through the active testing (where the Foxwell controls the car, turning things on/off/etc.), I was able to get that code cleared, but then it came back after a later attempt to clear the airbag code. I'll do some googling on this, but am not too concerned.

Despite multiple attempts to reset the airbag, running the active test thing, I can't clear it. Not even to clear and have it come back right away.
But regarding Foxwell functionality, it sure seems like it thought it would be able to do the reset, leading me to believe that I might actually have an airbag control module issue.

Service Now continued to be displayed each time I'd repeat things. But then I noticed an alternative menu option vs. Diagnostics, was "Hot function." I will guess that this means it is a separate function that Foxwell wrote that does not fit in the standard diagnostics framework. After "Hot function," I chose "oil reset," and then "maintenance interval." It gave me options to choose - e.g., Cayenne from 2003-2007, which is what I chose. I did that and probably told it to reset itself and the "Service Now" is gone. I did not look carefully, but I would not be surprised if every Porsche was available to choose from. I can see how others may have missed this, since it is not in the tree under Diagnostics. Easy to overlook.

Also confirming, this is with the Sept 2018 (shown on the website as 4/9/2018) Porsche SW update version, which came pre-installed. Like acer54 said, probably from the eBay seller. This unit shipped from Hong Kong last Friday. I had earlier found the following link which explains how to install the Porsche SW in case it is not pre-installed. Probably also helpful to do SW updates.

Thanks for the update very useful information regarding the Foxwell NT520, on a side note maybe it would be prudent to get the airbag code checked as you say it might be genuine and not spurious.

 

 

 

Wow, thanks for the lead. I've spent hours googling on this topic without much success, and your post there led me directly to the following, which has some results giving me optimism for a DIY fix:
https://www.renntech.org/topic/45757...lt-1217-fixed/

I'll follow up with any results.

Amazing how sometimes an individual's knowledge can outdo even the goog.

Also, more specific to the Foxwell vs. my actual (potential) issue here ... it is not exactly clear what is going on during the "Active Test" here. Some of it is clear, and it definitely does something, like clicking the door locks and turning on the hazard lights. But at some point, it seems to be in a mode that will last indefinitely and there are no clear instructions on what to do. And many instructions are unclear and some are just wrong, such as, "press [ESC]", where there is no such key. But it might be that I do have a failed airbag control module, and that's why the active test does not complete.
