Anyone brave enough to try these direct from China at £45 for four delivered? (Evora and other Lotus cars listed in the full description too...)

💰 Look what I found on Wish! I'm giving you £4 off your first purchase with code: lknczcr

It’s a very good idea. The system is so unreliable and inaccurate that I’ve had it turned off for years. 😜

Mine isn't. I checked mine when I first got the car and 3 of them agreed with my tyre pressure gauges, the 4th was so gummed up I couldn't get air in or out. Once replaced it's worked faultlessly for over two years of my ownership. I rely on mine when driving, for confirmation of correct pressure and that I haven't got a puncture ..  if I had I'd be putting air in before it got soft enough to overheat and damage the structure.  I'm wondering if you've experienced the 'cheap Chinese' variety ...

Nope. Only Lotus OEM/GM. Still rubbish though. 

I could go into the detail of why the TPMS is on the car and who it is really aimed at. But I won’t. 😉

Go on then ... as a Member of The Institution of Engineering and Technology I'm always interested in a well considered opinion, but have a low tolerance level when it comes to bullshit...😜

Oooh, get you. First, let me find a suitable emoji: 👜

Secondly, as an esteemed member of the blah de blah, you will be aware that the TPMS is fitted because of a regulatory/legal requirement: https://en.m.wikipedia.org/wiki/Tire-pressure_monitoring_system (2008 for the USA, 2012 for the EU). The system is primarily aimed at those sorts of drones who do not, or cannot, check their tyre pressures themselves. So they need to the car to do it for them.

Unfortunately, the system that Lotus chose to implement on the Evora is a) very unreliable and b) quite inaccurate. The system produces so many erroneous warning messages that the driver would be de-sensitised to an actual ‘sudden under-inflation event’ (ie blow out). Additionally, I’ve experience indicated pressures which can be 0.2-3 bar away from actual pressures.

I would hope that any self-respecting Evora owner checks their tyre pressures reasonably regularly (even visually) and that if one of the tyres did lose pressure quickly, they would feel and/or hear it whilst driving. If they couldn’t do that (and they needed to rely on a TPMS), then I would question if an Evora is really the right car for them.

Have you tried doing this for the later post 2017 cars with part A132G6017F  my maxitpms does not read/recognize the sensors in my evora (they are fitted as the come up on the cars display) and the evora options on the machine only have the older part number referenced in its display. I have to the latest version, only really bought it to program via cloning a set of black wheels for my wife's RR evoque, and it worked well for that. The reason I ask is that if i bought a spare set of wheels for the evora i thought i get the tpms working to keep the car happy..

keith.

Thought I would update what I have found out. The new lotus sensor is an alligator sensor  that can be programmed with the alligator programmer (and is also a lotus part T000T1543F), but it needs the software to be downloaded from the lotus cars dealers web site - not lotus techcentre. Found these details on a lotus tsb 2019/02 - downloaded from a USA website

The maxitpms / autel programmer is unlikely to support the new sensor as I emailed them and there response was  

We checked this model year, it has very little market share, sorry currently we have no detailed schedule to cover this.
 
So this also means that the later elises and exiges will not work on the autel programmer.
I have a new lotus sensor and at the moment I do not know if it has been programmed or not, so will have to try it one day.

Went out for a run today after fitting a spare wheel/tyre with the new sensor and the car picked it up automatically after a few miles - the original 3 were shown within  a couple of hundred yards. . Have ordered another sensor to fit to the next wheel I have. The guys who fitted the sensor supplied a suitable stem and including fitting it was £10 cash.. (lotus stem cost over  £30 + vat.

I did, absolutely.

I've seen worse reviews for many UK companies 🙂

Watching all this with interest as I'm going to do a pre emptive update on all of mine when I swap the tyres next month. They've been on since new so 11 and a half years ish so I'm well past the expected battery life expectancy

I bought my LE in November 2018 on very thin summer tyres with TPMS but saw a set of wheels with winter tyres for £600 before I'd collected it. They also had TPMS sensors but I found one of the TPMS sensors gummed up with tyre repair sealant and couldn't get air in or out so ordered a replacement from my Lotus Dealer (LB121G600F plus nut, bottom line £75.42). Not bad to get full set of wheels with winter tyres for £685 including fitting sensor.

Having got the new sensor in my hand I saw GM and 13227143 on it so did a bit of browsing...  also used on Saab 93 and others..  available on ebay for about £25. Damn it!  .. but you've got to climb the learning curve. Kept my eye on them and bought 4 for £76 to go in the original wheels when the summer tyres are replaced as I'm also beyond the life expectancy.

I did look at cheaper variants but I know these will communicate with TPMS and last about 10 years as they are what Lotus use. Didn't think worth gambling on cheaper and risk fitting & swapping charges if they don't work, not to mention the inconvenience .. but I'm also watching with interest..

Well that was quick!   Grandado-ordered TPMS arrived this morning. Exactly the same as all the other versions.  9 days to get here from China, cannot argue with that!

Let us know if they work! May get some myself!

I am following this with interest as I shall soon be changing mine. I recall from a previous thread that the date of manufacture is stated on the packaging. I also notice that in the top left corner of the photo of an old sensor, posted by @phil flash, there is what appears to be a date stamp indicating 12/10. So, @EGTE, what date of manufacture does it say on the ones from Grandado?
