Secondhand MK4

[edam]

I am thinking about buying a secondhand MK4 as they are starting to appear. Has there been any problems with the first ones to come out?

Had mine since July, no problems so far.

Depending on model you choose check availability and price of tyres. Some variants have uncommon tyre sizes and choice can be very limited.

No problems with my Crosstar (bought July 20) that might have been fixed in later production (annoyances such as RDMS are features we all have to live with so that Honda can get the top safety rating).

What about the Tyre Pressure Sensores which do my brain in on the MK3

Only had 1 alarm 2 days after picking up the car.
Did a recalibration and no trouble since.

No problem so far. I can't remember whether I did a precautionary calibration after getting the vehicle but haven't touched the valves since then but I wouldn't be surprised if Honda refined the algorithm which triggers the alarm.

Have a 2012 Jazz, and quite pleased I do not have to go through all that hassle with TPMS.  Have a real handbrake currently . Have a real arm as well ! What happens with TPMS when tyres (and valves) are renewed, and how much do the valves cost ? As eventually I will have to get a more up to date car.

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

The valves are not different. The Deflation Warning System works on the rolling radius and rotational characteristics of each wheel and tyre.
I only had a few false warnings with the MK3,  the MK4 appears to be better.

The tyres on the Mk4 EX are the same as on the Mk2 EX (185/55 R16). They did tend to be more difficult to source when I first got my Mk2, but there's much more choice available nowadays.

After changing tyres or even adjusting the pressures you need to remember to re-run the calibration (tyre fitters won't know how to do that for individual vehicles). The calibration is so that the car knows how fast each wheel rotates relative to the average of the four wheels (and can therefore accommodate different amounts of wear). If the system subsequently detects that there is a significant change from the the calibration condition then it will give a warning.

MK4 will be under Honda warranty, find one you like driving then negotiate hard & enjoy it.

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 ?
