Hi everyone! Thanks for reading my post.

My question is very specific and its about TPMS - specifically on the 2007 DB9. I have had the car for (6) years and now the tpms warning has been on and am unable to resolve the issue. I have taken it to (2) luxury shop/garage for repair but unable to fix. Initially, they replaced the tpms sensors on the wheels, but they were for the SMART tpms system, which this car apparently does not have. Then they were replaced with OE valve/transmitter sensors from Scuderia, but still didn't resolve the issue.
Can anyone confirm if it is a module issue or another part and if there is a specific sensor combo I should be looking for?

I appreciate any help on this - we do not have an AM dealer in Las Vegas and have only found (2) shops willing to work on the car but neither has been able to resolve the problem. Thank you again!

 

Hey ed..just to confirm..you do not have this in the passenger footwell…

 

Thanks Import!
No I don't have the SMART system. Originally they replaced the tpms assembly with the color coded ones for SMART, but the shop said it wouldn't connect and figured out it wasn't a SMART system. They are basic 433mhz sensors but I'm wondering if they are not compatible with the module or if I just have the wrong sensors on there.

 

FYI, 2007 is Smartire system and even with OEM sensors they are not self learning. Sensor codes need to be programed into the module to enable them.

 

This may be possible with a ThinkDiag 2 OBD tool. They are very low cost for the number of special features you can use on AM. I have the later Beru system on mine and can access that with that tool to reset it.

 

FWIW- I have the same MY DB 9- I removed (unplugged) my Smart tire box 7 years ago. No Speedo warnings at all. Invest in a excellent tire gauge. I check my tires on a regular basis, its a good practice. If your tires are 6+ years old give them a good look. Depending on Brand they can get weathered and hard no matter the miles you have on them. There is an old DYI thread on this topic as well.

 

In the end I bought the defeat cable…and like 07sportpack..I just check before driving…mine isn’t a daily..so not on issue…
