Secondhand MK4

[peteo48]

On the Deflation Warning system on the MK3 Jazz I have had severe issues with both cars. This current one is new and gave me, iirc, 4 false alarms almost exclusively after motorway cruising, the same happened on my first Mk which was used - 3 false alarms.

Both cars settled down eventually after repeated recalibration.

Didn't yours go back to dealer to be made less sensitive, or 'tweaked' as they may have called it ?

In the end it didn't. We had an agreement that the next time the DWS went off I would not recalibrate and take it in with the warning light on. That was the last false arm, it never went off again!

There are no TPMS valves on the MK3 Jazz, it uses the ABS sensors to measure any circumference differences - cheaper!

Is this also valid for the new generation of Jazz? No TPMS on wheels?

They do have TPMS - tyre pressure monitoring system. Its a legal requirement.   My 2024 Jazz still uses the  indirect tpms system which measures the rotation speed of the wheels   . A tyre that loses air pressure  gets slightly smaller and starts to rotate  more times per kilometer when compared to  the other wheels.    What it doesnt have is a   tyre pressure sensor valves in each tyre   which send individual  radio signals to the car.  These sensors are quite expensive to replace when their batteries eventually go flat or if you need to buy them for a second set of winter wheels etc.

   My previous EX activated the tpms after about 100 miles from new, possibly the tyres 'bedding in'. Others have reported similar  with new tyres.       I have just completed 1200 miles  from new in my 2024 Advance and no activation so far . So maybe they have improved the system.

When new, all tyres should bed in at the same rate

I've had 4 new Hondas with TPMS and never had any issues from new

Maybe, like my first dealer, they had the tyre pressures all over the place and when corrected TPMS spotted the change

Calibration of the system involves driving at speeds up to 60 mph (check the handbook for exact details of calibration procedure). I doubt that they do that at the factory or during the dealer’s PDI. So it’s likely that new cars haven’t had the system properly calibrated, hence the false alarms at low mileages.

Ive had a few TPMS funnies over the years on the Crosstar,  What ive found is that once the TPMS has been recalibrated, its best to switch of the power and then power up again before driving.  I dont know why this makes a difference but it does.  If you dont, then 20 miles down the road, the warning sometimes comes back despite pressure being checked and A-OK.
