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.

tried enabling indirect TPMS on my 11/2007 Skoda Octavia but no luck

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.

Does anybody have an idea of what could be happening ? Are we missing some extra codification ?
