Ok typical TPMS need to change batteries every 2 years or so, be it internal or external type. I ask because I got my car used and never ask previous owner when he last changed it, so I do not want to be caught in a situation where need to replace its batteries just after I change tyres. So I checked around, then I read that for Mercedes car need to change whole sensor as not serviceable. So I posted it here to get some answers. Anyway I just got the answer from my workshop contact. Indeed it is not serviceable, need to replace whole module. Total 4 sensors would cost about $800! If do in AD workshop would be more to much more definitely. I can only say Mercedes cars really atas. And this is for the lowly B180. Higher grade Mercedes might cost more.

I am driving a E250 and not aware of such "batteries" other than the main battery and a smaller one meant for the start/stop function which should cost no more than $350 and $180 respectively if replaced at a workshop like Chip Soon. The only brake related sensor i am aware of, cost no more than $8 per sensor. Your B180 so complex? Edited October 12, 2019 by Nav14 Link to post Share on other sites More sharing options...

One main battery and one mainly for start/stop function. What is TPMS ? Tyre change and sensor can only refer to the sensory wire for brake pads which cost no more than $8 per sensory wire. TPMS = Tyre Pressure Monitoring System. If your Merc is newer ones, mine is 2015, it should come with this feature that allows you to see your tyre pressure through dashboard display. There will be 4 internal tyre pressure sensors in the wheels, which can last a few years as self powered. But not many know that they are not serviceable, like me haha. And it is expensive! My quote is through Chip Soon. C&C should cost much more. Edited October 12, 2019 by Heartlander 1 Link to post Share on other sites More sharing options...

I can only say Mercedes cars really atas. And this is for the lowly B180. Higher grade Mercedes might cost more. OK, let's say you're right. Or that the workshop is giving you reliable info. Remember that it's in the interests of any workshop or parts supplier to agree with you if you start worrying about whether this or that needs to be changed. As an example, I had my M5's DCT fluid changed for piece of mind, even though it's supposed to be a "lifetime" component according to the AD and BMW themselves. But online forums and pro mechs and worried M car owners in Singapore were all in agreement that it's a "better safe than sorry" sort of thing. The 3rd party workshop never argued with me, they were quite happy to do it, and they did a proper job, no complaints. The same sort of thing happens when people service their cars every 5k km rather than the more usual 10 to 15k interval recommended by most German manufacturers. And then there are those who tell you you should change everything pre-emptively, even key fob batteries. Just in case costly "re-coding" is necessary if you let the batteries go completely dead. What I'm trying to say is that in your place, I would just have let the TPMS soldier on and see how much life it had left. If it died soon thereafter, no biggie, if the replacement cost close to a grand, you wouldn't have saved much doing it with the tyre change anyway, so what did you lose? And it might have surprised you. Basic mantra: don't try to fix what ain't broken, especially for a non-critical non-wear part. And if you think these bills are "atas", I don't want to scare you with the preventive maintenance I pay for my current car lol. 7 Link to post Share on other sites More sharing options...

Online mentioned 4 to 6 years, 7 years also have. My intention here is to get feedback from current owners on actual usage and experience. But I not so hopeful as I know most owners change rides every few years, so most likely do not know at all. Actually I quite curious how much you paying to service your atas ride. Just the most expensive interval will do if you can oblige. I do not know many atas people. Link to post Share on other sites More sharing options...

I don't consider myself atas in any way, shape or form. But since you asked about service costs, last service at McLaren in March this year was 3100 before GST. I also bought 2 years warranty cover at 13k before GST (one year would've been 6800 so less lugi since I love the car and intend to keep it).

Old-driver 5th Gear October 12, 2019 Share October 12, 2019 I've never been concerned with this feature; this is probably the least of any issue. Useful though, as a warning came on recently due to a `leak' on one of the tyres. Just go check and pump the tyres weekly and save the $800. Link to post Share on other sites More sharing options...

Mkl22 Twincharged October 12, 2019 Share October 12, 2019 I would leave it and fix it when the battery runs out. Labour to replace the the sensor would not be that ex anyway. Link to post Share on other sites More sharing options...

therock Supersonic October 12, 2019 Author Share October 12, 2019 I think one disadvantage if one regards it as so is that Merc cars cost more to service than say a Toyota but they are already amongst the cheapest of the premium brands see the list of workshops 1 Link to post Share on other sites More sharing options...

Total of oil plus transmission and clutch fluid and miscellaneous crap came to 4760 before GST (about 5092 after GST). If really cheaper than Jap makes, that's good to know but let me know which make and model so I can avoid. Thanks in advance. 2 Link to post Share on other sites More sharing options...

I drove to the merc centre and had it fixed for $10 and took the opportunity to rotate my tyres at the same time. If you are concerned about the high cost of replacing the TPMS when the car is 6-7 years old, consider switching to non-run flat tyres (which will be cheaper than run flat) and put in a tyre repair kit in the boot and/or have your AA membership for service on call.

Thanks for sharing your experience. This feature has also alerted me of a punctured tyre awhile ago, certainly find it useful. My surprise was more on the high cost of replacement due to non-serviceability of the sensors. Coming fr jap/kor cars i had not expected it to be such. Good thing i came to know about it now, so less of a shock when it happen later. Just another thing to pay for. I do not like run flat tyres option as noisier. Worse czse would be installing 3rd party TPMS system with internal sensors and separate display unit, which will cost not more than $300. Only drawback is need to change batteries every 2 to 3 years. TPMS with external sensors are even much cheaper and can do it yourself, as done for previous Vellfire. Wait and see lah. ↡ Advertisement Link to post Share on other sites More sharing options...
