Thread: external TPMS for D4

Won’t be 3M tape either. Just a knock off.

I don't use the valve caps because I can't be bothered taking them off and putting them back on every time I have to air up or down and external sensors would create the same problem for me.

I always thought not using valve caps could be very dangerous if the valve suddenly failed, (not sure of the likely hood of this) as it would not have the cap to slow the air rushing out, so would almost be like having a blow out. I've had one of those before in a Nissan ute, (co car) and I ended up on the opposite shoulder of the road, luckily no oncoming traffic!

I don't have any experience with these, but the company sells good brands like, Tuffant, Llams, GAP IID, etc.

I have never had a valve fail completely But Yes they do tend to leak once in a while and a valve caps won't stop this.
Every time i air up/down I put a little bit of spit on the valve stem to check it is working, If not I replace it with a new one
I have had my fair share of blowouts but a leaky valve is nothing like that.

I would disagree (respectfully) with you there.

Pre-TPMS I used steel caps with seals and they will seal.

Like you, I also do the Spit test. I will always cap them though.

I am using the Tyredog external sensors with the colour display,all works well and cheap enough on ebay.Have found the sensors flexing on the valve stems on corrugations/rough roads have worn grooves on the mag wheels, can be prevented by using foam tubing[air con] on the stems.
