MK3 Leon FR 150 vs MK4 Leon FR 150

We've recently switched from a MK3 LEON 1.5 FR 150 to a like for like new MK4 LEON 1.5 FR 150. Having had the new car a few days, some initial comparative thoughts are as follows:

Positives:

- Despite being on paper the same engine, the FR150 seems smoother in the MK4 than the MK3.
- Early signs are that the fuel consumption is also better on the MK4 (52mpg on a 30 mile mixed road trip)
- The Sat Nav is a considerable step up from the old.
- The media player and radio are also a step up in terms of functionality and ease of use.

Things that don't seem as good (at this point):

- Our largest "gripe" is the the Lane Assist function that was not present on the MK3. On country roads or on roads where a cycle lane is present it is a real pain if not a dangerous distraction. It kicks in too soon or misinterprets the lines in the road. On a number of occasions, I was driving around a bend and it twitched the steering wheel to indicate we were too close to the centre line when, in fact, we were a considerable margin away from it. Switching off the Lane Assist function brings a permanent warning sign onto the dashboard. I would like it configurable so you can specify a higher minimum speed that it commences working (e.g. 50mph) so that it mostly kicks in on dual carriageways etc.
- The seats in the MK4 FR do not seem as supportive as the seats in the MK3 (notwithstanding the presence of lumbar control)
- The front parking sensors do not seem anywhere near as sensitive than on the MK3. Getting someone to walk a foot away from the front of the car (with it engaged in first gear) does activate it so we know the sensors are operating. However, slowly driving towards objects when we're parking does not activate it. We'll likely get this checked out by our garage when lockdown finishes.
- When using the sat nav in auto day/night mode, it switched to night mode when we went through some shaded woods but did not switch back to day mode when sunlight returned. We had to resort to manually forcing it back to day mode. This feels like a software issue.
- Driving the car in twilight, the dipped beam did not seem as strong as on the MK3. At one point, we wondered if we simply had the running lights on. However, the Auto mode on the headlamps was showing we had dipped beam on. We'll do a test in full night mode at some point to see if things are better.
- We do miss the rotary climate controls from the MK3. Also, at night time, the hot/cold sensor controls below the infotainment screen do not light up.
- I have not found a way of manually adding icons to radio stations (e.g. Capital or Heart) that do not have them. Again, in the MK3, you could load icons manually.

Would welcome any thoughts/feedback on the above from other forum members.

Nice review.
The software does seem a bit rushed - it seems to throw up errors a lot
Possibly the parking sensors aren't aligned or set up properly? Flag it now and get it fixed later.

Re the Parking Sensors, having tracked down the respective sections in the handbooks, it looks like SEAT have reduced the sensitivity of the front corner sensors from the Mark III LEON to the Mark IV LEON (see screenshots attached).
Mk3 p234
The approximate measurement range of the
sensors is:
A 1.20 m
B 0.60 m
C 1.60 m
D 0.60 m
As you approach the obstacle, the time interval
between the audible warnings will be reduced.
When you reach around 0.30 m the
warning will be constant: do not continue to
move forward (or backward)!

Mk4 p285
The approximate measurement range of the
sensors is:
A 1.20 m
B 0.60 m
C 1.60 m
D 0.60 m
As you approach the obstacle, the frequency
of the audible signals will increase. The signal
will sound continuously at around 0.30 m:
Stop!
Looks the same to me?

That's interesting and definitely not our experience having just moved from the MK3 FR 150 to the MK4 FR 150. Doing the same parking manoeuvres in front of our house with the new car generates virtually no alerts whereas that was not the case with our last car. Out of interest, what date was the MK3 manual you were looking at? The diagram I took the screenshot of was on page 303.

Hmmm... Googling the 11/18 Mk3 manual shows -
The distance of separation from the obstacle can be estimated using the segments around the vehicle.
The optical indication of the segments works as follows:
White segments: they are displayed when the obstacle 30 cm away from the vehicle or further if it is not within the vehicle's trajectory or the direction of travel is in the opposite direction to its location, and also when the electronic parking brake is activated.
Yellow segments: obstacles located in the vehicle's trajectory and which are more than 30 cm away from the vehicle are displayed in yellow.
Red segments: obstacles that are less than 30 cm away from the vehicle are displayed in red.
That's super helpful and specific :mad:
Edit: approx ranges found -

1.20 m
0.60 m
1.60 m

The 11/19 manual has the same ranges - so "officially" the Mk3 and Mk4 sensors should be comparable. Won't be able to check until the GF picks her Mk4 up, so others might be able to help.

That would be really helpful to know. As per my earlier post, it's only the front sensors that appear less responsive than the MK3.

I find the same problem with mine, I do not get a warning at all until I am on top of a obstruction and then it suddenly turns red and a continuous warning sound, it’s very unnerving but when I have a look to see how far away I am it seems sometimes it not that close.
