How to: retrofit indirect Tire Pressure Monitoring in 5 minutes. (7K6)

[Dana @ Ross Tech]

Yes and that makes sense based on the 2011 NAR VWs with Indirect TPMS and that bit enabled from the factory.

I have turn on tpm on my octavia mk2, 2.0 tdi, 2007y, and it's working, and i have instaled the reset button, connect on ABS controler pin35, but the reset button doesn't work, on measured blocks in vag com for this button don't change from not operatin to active when i press the reset button.
Does anybody know what to do that the reset button work,maybe is wrong pin,but i cant find the pin list of abs controler to check it out.

hi gurus, on my 2011 Caddy I tried to enable Bit 2 (to change from B1 to B5) but the coding is not accepted: Error 31: Request out of range

any ideas? I had a rear tyre go down to 20psi and thought I should have another crack at this

Hi Lams, I haven't chatted with you lately and I see that this post was quite some time ago, but I have some new news for 2012 cars that I wanted to share with Logger. This was a 2012 Canadian market Golf TDI and they do NOT have factory TPMS up north:

Anyone know why I'm getting this error with CAN gateway? - TDIClub Forums

In summary:

1) The cluster coding was needed.
2) The normal TPMS Byte 16 bit needs to be enabled in the MK60EC1 ABS.
3) The Tire Pressure Monitoring (TPMS/PR-7K6) via Instrument Cluster in Byte 17 (per the latest VCDS release) needs to be enabled AND it is believed most of the 2012 MY vehicles will support a TPMS reset via the cluster/MFA/Maxidot instead of installing a switch or using a scan tool and basic settings. My 2010 cluster does not support this but any feedback would be great.

Perhaps slightly OT, but I have an experience to share with the factory indirect TPMS in my MY12 GTD.

Background:
About 2 weeks ago, as I rounded the last corner on my commute to work, I received a tyre pressure alarm. I rolled the last 300m to work, parked, couldn't see a flat tyre, decided I would check on the car throughout the day.

By the end of the day, none of the tyres were visibly flat, and the warning light was still on the dash. I drove approximately 1.5km to the nearest servo, and checked them all. (A month or two earlier, I had set the tyres to 230kPa (warm) and reset the TPMS.) On this occasion (after dark on a cold winter's day) three tyres were around 200kPa, and one (rear right) at 170kPa. I pumped them all up to 230kPa, and (having NOT read the manual properly) drove a few hundred metres to see if the alarm would reset. It didn't, so I pulled over and pushed the button until the system beeped and the light went off.

Work has been hectic (yes, I'm making excuses), so I didn't think much of it until I set off on a work trip to Eyre Peninsula. In Port August (300km from Adelaide) I stopped and checked pressures. Three tyres were a little under 240kPa, the rear right was a little under 230kPA. I brought it up to 240kPa & continued the journey. I did not reset the system at this time.

After reaching our destination, and spending a few long days of work (more excuses) & local running around (maybe two or three hundred km) it was time to come home this morning. After approximately 150km of highway running I became aware of the car "wandering" a little in a straight line. My first thought was a flat tyre, but there was no alarm, so I started watching the road for something that would cause tramlining. When I couldn't spot anything to suggest a problem, but couldn't deny there was a problem, I pulled over. One severely deflated rear right tyre, without a low tyre pressure alarm. The tyre wasn't on the rim, but we could here it suck air in and re-inflate as we removed weight and the tyre regained its shape.

Put on the space saver (the original wheel was warm when we pulled it off), drove half an hour at 80km/h and called into a Bridgestone outlet. Fortunately, the tyre was repairable, and I have never been so happy to hand over $22. Reset the system with ignition on but engine off. Drove about another 45 minutes, checked tyre pressures in a servo (repaired tyre was at 266kPa!), noted all wheels were cool, not warm. Not that I think this is relevant, just found it interesting.

So I'm trying to figure out why I didn't get an alarm. Having read this thread, my first guess is that a slow leak prevented the system from properly calibrating. I will admit that I didn't think about tyre pressures at all since I checked the pressures on Monday.

Another (less likely?) alternative is that I didn't reset the system properly. The handbook says to turn on the ignition and reset; I drove before resetting, and reset with the engine running. Could that really cause a problem?

I spoke to VW, and they have no suggestion. They want me to bring the vehicle in for a check, which isn't exactly convenient for me at the moment. They've made a note for codes to be checked at my next service.

So. That's my experience, and I suddenly have a greatly reduced faith in this system. I'm guessing that I've done something wrong, but I'd like a better idea of what that was.

Thoughts?

How long after you noticed the car start to pull, did you pull over? It sounds like the deflation was previously at a fairly constant and very slow rate, and the condition of the tyre somewhat suddenly deteriorated during your drive home.

So I'm trying to figure out why I didn't get an alarm. Having read this thread, my first guess is that a slow leak prevented the system from properly calibrating.

I'd say this is a likely contributor. Remember the system works based on the ABS sensors and wheel rotation speeds, so if it's a constantly moving target for the system to calibrate against, and the deflation is slow enough, it may have been constantly recalibrating.

Another (less likely?) alternative is that I didn't reset the system properly. The handbook says to turn on the ignition and reset; I drove before resetting, and reset with the engine running. Could that really cause a problem?

I seriously doubt it.

It'd definitely be worth taking a look at the car to see if there are any relevant codes. If you don't have time to head to a dealer, and this issue concerns you, speak to myself, Transporter, or one of the other Adelaide members with VCDS and we'll scan your car and check for any codes.

I have enabled this feature on my 2006 MkV Jetta and it works just fine.

I would like to have the functionality of the OEM reset button.

Does anyone have a wiring diagram showing the module and pin connection for the switch?

P/N for the switch

[jkmboler]

Anyone???

I've got the 7k6 activated on a Jetta MK5 2010 (white MFD), including the reset button installed. Seems to work fine, the light turn on when I start the car, and if i press the button a couple of seconds, a beep sounds and the system resets, but sometimes all the lights in the cluster blink once and for a little time had the steering wheel light turned on in yellow. This happens after i've got the tpms installed.
Checking a scan it says there is an intermittent communications problem between Steering Assist and the ABS.

Revisited this today & it appears I've been successful. Mine has a MK60 ABS controller (not MK60EC1). There was no long coding helper in the ABS Controller - it requires you to add up the option numbers and do software coding. The tickbox for ""tyre pressure monitoring 7K6 installed is in the Instruments Module (IIRC).

I'll drive it about & test it for a few weeks & post my how-to in the Skoda area & link back here if it works properly

Hi, I have a Polo 6C from 2016 which i changed the original radio/screen, so now i cant reset tpms alert.

Do you know if its possible install the set tire Pressure button in the glove box? Or any retrofit kit?

I know that others Polo 6C wich does not have touch screen, have a switch in glove box... But my car not.

Thank you.

[sergio279]

Retrofit fully functional 7K6 Indirect Tire Pressure Monitoring, (No TPMS reset button required).

This may be of interest, if like me; you have a lesser MK6 variant without TPMS. If your car came without the system it will not have a reset button. The rest of the hardware for the system to work, including the warning light, is already in your car. It is just not activated.



Benefits: Enables option [7K6] TPMS in cars shipped without TPMS [7K0].
Does not require a Reset button to be fitted.
No additional hardware required.
Cost: Nothing, provided you have access to VCDS
Target: Mark 6 Golf without factory TPMS button
Requirement: Car with MK60EC1 ABS controller and access to VCDS
Time involved: 5 minutes
Downside: Requires access to VCDS again, to reset a Warning light, OR to re-teach new values.

On the basis that it is free and considerably better than nothing, I have activated, successfully tested and intend to use it. Usual caveats - All modifications and changes are done at your own risk.

What is 7K6?

7K6 is the second version of the VW indirect Tire Pressure Monitoring System (TPMS). It uses the ABS system to deduce and warn you when a tire is going, or has gone flat. VW appear to have renamed it “Flat tire indicator” to differentiate it from the several “direct measurement” TPMS systems that it has also produces.

I have found that it will detect a problem tyre with a 5psi (15%) pressure drop from 32psi and start error counting. It will trigger the warning at 6psi or ~ 19%. The System is quicker to detect a rapid drop than a gradual deflation. Letting 6psi out in one hit will be detected in ~ 2 minutes and trigger a Warning in ~ 8 minutes. Letting out 3psi followed by incremental 1 psi drops to 6 psi will take longer for the Warning to develop once at 6psi.

Short Instructions.

Activate TPMS 7K6

1) Check you tire pressures are correct. At least even Pressures laterally.
2) In VCDS VagCom go to your ABS controller > Coding > Long Coding Helper > and toggle byte 16, bit 2 ON.


ABS controller [Coding - 07]


Coding


Long Coding Helper


TPMS OFF


TPMS ON

3) Confirm system is active by turning IGN ON. Observe momentary TPMS light beside 180kmh on the speedo.



END

Reset the System
(Emulate the missing TPMS button);
- to clear a Warning.
- to teach system after reconfiguring tires.
- to teach system after modifying pressures from previously calibrated state.

1) In VCDS VagCom go to your ABS controller > basic settings > enter 042 in block field > GO > That’s it.


Resetting System. Showing EEPROM Reset message to confirm it has reset.

2) Chime and Orange TPMS light will go off (if it was ON).
END

De Activate TPMS 7K6
(Perhaps when Selling your car)

1) In VCDS VagCom go to your ABS controller and toggle byte 16 bit 2 OFF
2) Confirm system is inactive by turning IGN ON and momentary TPMS light no longer appears.
END


Note: After activating or resetting, the 7K6 system will need at least an hour of driving including highway speeds to fully adapt and correlate wheel speeds with correct tyre pressures before you can rely on it to give a Warning. Do not partially deflate a tyre in this period to test the warning. The system will not have learnt sufficiently to trigger a warning and it will invalidate the teach in process.



Request

It would be good if we can keep this thread on the topic of activating and using the 7K6 indirect system. The direct system is undoubtedly better - that is not what this thread it about.

If you want to debate the merits of the various TPMS systems or think this system is rubbish, go to the Tyre Pressure Monitoring thread which discusses this. If you want more detail and opinion on the merits of TPMS systems or are interested in how Mavericks supposes it works, go to his TPMS thread. Although I have found the assertion that it “will only alert after 25% of pressure has been lost” is incorrect. I have found it to be between 15% and 20%. Splitting hairs here I know. The speed of which the system learns is as much related to the speed at which you drive as the straightness of the roads. It will not learn anything at all after a reset, if you do not at some point get it up to highway speeds. I believe you could drive around town indefinitely and it will never gain enough information to calibrate itself. So a Highway drive at some point is essential if you want the system to function as designed.

Anyhow I hope this info will be of interest to some of you.

Hi, when i try to access to "Basic Settings" the widows wichs opens is different for me. You can see:



How can i solve it? Thank you

Can someone help me with this. I have a 2012 MK6 GTD DSG. No tpms button or anything and no light comes on the dash when i have a really low tyre. I tried activating through vcds and accepting the coding but when i turn ignition on and off there is no tpms light that comes on? i have the correct abs module mk60ec1

Have you got a TPMS button in your glovebox to set your pressures? Im not sure what is fitted to your car as its a UK spec and this is predominantly an Australian based forum, therefore its quite possible that UK spec cars have some differences to AUS spec cars.

But in Australia, a Mk6 should have a button in the glovebox to set your tyre pressures. The rims/tyres themselves do not have TPMS sensors in them, rather the car uses the ABS wheel speed sensors to detect differences in wheel speeds from an underinflated tyre, and uses that info to signal a warning on the dashboard to check tyre pressures. Its a pretty basic system, and its slow to react (unless you have 0psi in the tyre), but it does work....eventually.

The issue with the Mk5 and Mk6 Golf, is that the ABS wheel speed sensors are a very common failure item, and the sensors need to be replaced (should be about £20 for each sensor). Once replaced and working again (assuming no other issues) then your ABS will be functional again and your tyre pressure system should work.

Have you scanned the car for faults? Do you have faults for the wheel speed sensors?
