2012GLK350

Hi All, this is my first post here (not first time visiting) - I cannot seem to find any information here and my dealer has not been helpful.

Our 2012 GLK350 has a defective TPMS module (the computer, not a wheel sensor). I can't seem to find any type of diagram showing the location of the module to even be able to access it, pull it and get a part number. There is some conflicting information as to whether it is located up under the dash on the passenger side (near cabin filter) or under the backseat. It may possibly be located somewhere else entirely. There also appear to be 2 possible parts, one is a small, black rectangular module with two mounting tabs and the other is a slightly larger white rectangular module with a short antennae protruding from the module. I am wondering if the part was redesigned at some point in the 2010 to 2012 GLK models.

Can anyone confirm the location of the TPMS module on a 2012 GLK350? For what it's worth car has AMG package and 20 inch wheels, if that matters.

Thank you.

Here's the part: https://www.mbpartsworld.com/oem-par...bC12Ni1nYXM%3D

I'm not sure where it's located either exactly. Hopefully someone else can chime in.

Thank you, very helpful - now it appears that there are two module components!

Thanks

not necessary, it may depends on system, which you have in car, there are 2 options for flat tire warning...one is TPMS - this needs sensor in each tire and is more precise - newer years of GLKs, other one is based on suspension level sensors...so you need only one module for system equiped in your vehicle..

Interesting, thank you - I was told specifically by the dealer that the module was defective (not a wheel/tire sensor), my system is clearly the sensors in the wheel / TPMS system not the suspension sensor.

I suppose the easiest way to check is to go inside the wheel well area and check which module I have. The dealer did not give a part number.

Thanks!

That link in now dead. Is there any chance you could post up a screen shot or new active link? Mine's a '15 model, so it has the individual TPS sensors in the wheels. The sensors tested fine, so I purchased the the module (Part # A0009000800), but I'm having no luck getting a diagram of where the module goes. Obviously from reading above its behind the rear driver wheel, so I'll start digging around there tonight but the diagram would be great to have.

What model of mercedes do you have? This is GLK section, nr. 10 is TPMS module..

Thanks! I have a '15 GLK250. That diagram appears to show it in the interior behind the tail light, but I didn't see it when digging around in there yesterday. I guess I'll have to look closer.

I removed the panel in the hatch (the one intended for tail light removal) and moved the amp out of the way but still no TPS module. I'm lost or clueless - maybe both. Thanks anyway.

Are you sure, you have a TPMS system? Because GLK can be equiped with 2 different systems for tires..one is TPMS - this shows you exact pressure in each tire and another one, which is based on suspension level sensors and this system informs you only about flat tire...

huh my 2010 glk has the TPMS there when you open up that compartment its tan with a black tube sticking out.

Honestly I'm not sure. Here's what's displayed on the gauge cluster in case it maters. I'll do some research on the suspension based system and report back.
