Sensors and Service Kits
Q: What is a service kit?
A: A service kit contains:
1 cap
1 core
1 rubber grommet
1 nut
And 4 coloured rings (Renault)
1 zinc coated seal washer (VDO)

Q: Why do I need a service kit?
A: We recommend that you should replace the cap, core, grommet and nut every time a TPMS sensor is removed from the wheel or the wheel is serviced. Worn component parts can cause serious problems. Replacing the critical valve component parts every time ensures an air tight seal allowing the TPMS to function properly.

Q: Are all sensors the same?
A: No all sensors vary. There are some sensors that are for several different makes and models of cars but it is important to make sure the sensor is the exact one for your vehicle.

Q: I can't find my vehicle listed on your site - What do I do?
A: We are constantly updating our site with new vehicle listings but there may be a chance that we haven't got to your vehicle yet. Please drop us an email or give us a call and we will be happy to advise you on the correct sensor for your vehicle and how many we have in stock.

Q: Will my new sensor learn automatically or do I need to have it activated/triggered?
A: On the item description it will tell you whether or not the sensor relearns automatically. If you are still unsure or would just like to check it over with a real person, give us a call on 0844 2510503 and we will be happy to help. 

Q: My valve has just broken! Is it possible to just replace the valve part of the sensor rather than the whole sensor?
A: This really depends on what sensor you have on your vehicle. Some sensors have the valve as a seperate part, whereas other sensors come as one fixed piece with the valve. If you search for your sensor on our site, you should be able to tell from the image provided whether the valve is attached to the sensor or not. If you are still unsure or you would just prefer to speak to a real person, give us a call on 0844 2510503 and we will advise you.
