Okay, ABS on snow is always a tricky thing... I've also tried it with my Octavia. To turn it off, you just turn off the ignition. While there have been many improvements in terms of speed regulation, etc., the braking distance with locked tires is definitely shorter on light ice or snow. Whether ABS is better or worse for the average consumer... I have no idea. I learned to drive without it, so it's not as essential for me. The 'stutter brake' works quite well, and you also need to master that if you ride a motorcycle .


most cars were delivered incompletely; it was forgotten to connect all the wheels to the engine/transmission .


Well, in that case, I'll refer you to my signature .

Well, I'm still skeptical about this ABS thing. I think a lot depends on the tires being used. Our company's Golf 4 variant doesn't even engage the ABS when my Golf 3 already locks up. So, the only thing that helps is to buy good tires .
It's a shame, but if they develop brake fade during the first hard braking, they won't have ABS. That's also a significant advantage of ABS .

Hi,

Regarding the ABS deactivation issue: Does disabling the ABS in a newer car not generate a large number of error messages in other control units? Possibly even errors that would prevent the ABS from functioning properly after being reactivated?

Best regards,

Jan.

Hello,
Okay, I get along perfectly well with ABS.
It's simply not possible to brake and steer simultaneously on snow as effectively without ABS. Furthermore, I experience fewer problems with ABS during full emergency braking on the highway.
And if I ever want to drive without ABS, I can simply pull the fuse and that's it.

Sure, here's the translation:

'MFG' is an abbreviation for 'Mit freundlichen Grüßen,' which translates to 'Sincerely' or 'Best regards' in English.

Okay, comparison of the new (Touran, manufactured in 2003) and old (Passat 35i B4, manufactured in 1996) ABS systems: No difference could be detected. The frequency with which the brakes are released and reapplied is approximately the same. Otherwise, steering on a slippery surface is always a nightmare, regardless of whether you are braking and/or have ABS. Otherwise, I think ABS is a good system (at least the newer versions) and I wouldn't disable it (it's a personal preference), because it generally always chooses the best compromise between friction and slippage (at least where it's possible).

Best regards, WarLord.

Hi,
As a proponent of the deactivation option , I wouldn't constantly disable ABS, but only in situations where it is inherently overwhelmed (off-road) or where I personally achieve better braking results without ABS (snow).

Regards,
Jens.

I see it the same way.

Hi,

I have observed that ABS can be very helpful, but it cannot overcome fundamental physical limitations.

I can't leave it like that, because the ABS might be overwhelmed in icy conditions. A lot depends on the driver, and also a lot depends on the tires.

30m irrigated sliding surface:

At 50 km/h with ABS, it's impossible to come to a complete stop within 30 meters.

A car traveling at 30 km/h with ABS will come to a stop in approximately 20 meters.

At 30 km/h, without ABS, it's impossible to come to a complete stop within 30 meters.


This suggests that sometimes, exceeding the speed limit by a few km/h can lead to being stopped and potentially facing other consequences. Accidents can be decisive.

Have you ever braked on surfaces with different levels of grip without ABS?

Without ABS, the vehicle immediately starts to spin and is almost impossible to control normally.
to master.

ABS makes things like that a non-issue.

I'll concede the argument about snow, but when and how often does one actually drive on a completely snow-covered surface? By adding up the days, one can hopefully arrive at a total of 1-5 days, which can be managed even with adjusted speed and ABS.

One should perhaps consider whether they should re-evaluate their own driving style if they constantly have to rely on their electronic driving aids.

Sure, here's the translation:

"0 points for anyone who didn't explain this correctly to you!" The trainers are only too happy to emphasize this point during a safety training session.
The braking distance increases with the square of the speed. This means that on a slippery surface, at a speed of 50 km/h, you will come to a stop after approximately 55 meters. Every driving school student learns this.

The skating surface simulates ideal ice, which is something you don't find everywhere.

While that wasn't the main point here, it was definitely correct.

Anyone who tries to do that with four wheels is to blame. Everyone should already have a little bit of feeling in their right foot.
If the wheels are still rolling on the more grippy surface, the car remains quite manageable and steerable. This is how it was always taught in safety training sessions "before the era of ABS," and it's still valid today! People rely too much on their electronic gadgets these days, and when those gadgets suddenly disappear, it's like being stranded in the middle of nowhere.

While electronics are helpful, they are not all-powerful!

If you drive to work around 5 am in the winter in this area, the snowplowing service is still peacefully asleep, and you often end up driving on fresh snow. But generally, you're right about that.

It happened again this afternoon.
From Wachenroth towards Schlüsselfeld / A3, expect sleet and snow showers.

The road surface is extremely slippery in places. The track is almost straight, so if you're going 50 km/h, you might end up fully engaging the ABS... well, let's just forget about the concept of 'brake.' It's more like a foot massage, but not much else.

Without ABS, the vehicle may slightly lose traction, but the stationary wheels scrape through the thin layer of ice, and the term 'BRAKE' becomes somewhat more applicable again .

At home, going uphill, then the game is reversed:

'Everyone's spinning around down there, etc. Up above, the snowplow is trying to get down, while we're all waiting down below (it's right in front of my driveway). Eventually, the plow backs up and goes back up the hill, and to the surprise of everyone waiting or giving up, I drive up the hill. I do it with the help of the EDS (ASR OFF) and a gentle touch on the gas pedal. It's quite a show. Then, the snowplow drives down backwards...'
Okay, my winter tires aren't *that* great... I can't imagine how bad it will be when it really gets icy.

PS: Of course, I know that the snowplow truck can't go downhill facing forward because it wouldn't be able to steer. Please don't make any comments about that...

You just have to get used to the hits from the EDS, which sounds really brutal.
But it's still better than that huge, obnoxious BMW in the right lane, which nobody could help anymore...

Hm, a special permit for overtaking tractors?

By the way: What exactly does ESP do when the rear of the car starts to slide on a slippery surface? That's what happened to my company-owned Polo yesterday (which doesn't have ESP), and I had to correct it. It's quite a thrill driving at 80 km/h and having a car approaching from the opposite direction in a head-on situation (luckily, I managed to react before the other car passed me - it looked quite dangerous though).

Best regards, WarLord.

@warlord:

What it should do: The front wheel is briefly braked to (theoretically) bring the vehicle back on course. What I'm starting to doubt, given the accounts described here...

Hi,

So, I want to share my experiences from the last few days on a deserted, snow-covered, and cordoned-off parking lot.

I must preface this by saying that I have a new ABS/ESP control unit for the past three weeks (which likely includes new software).
This traction control system reacts much more sensitively and smoothly, but in my opinion, even this system corrects oversteer far too late (for the average driver). However, at least on slippery surfaces, you can force the system to engage by giving it full throttle. "That works great, but it's pretty much the opposite of what you're told in every driving safety course (depress the clutch and steer gently)."

With ESP, you can wonderfully maneuver the car around a corner. Suddenly, steer sharply against the intended direction of travel (experts call this "counter-steering") - the ESP will then try to force the car in that direction - immediately steer in the direction you want to go, and the car will come around the corner with a clean, drifting counter-swing (again, the ESP helps here ). If you remain brave on the accelerator (the ASR/EDS will nicely reduce the power), you will exit the curve with such speed that it can be frightening.
However, it requires quite a bit of practice to be able to execute these maneuvers precisely (it took me some time to learn).
Previously, I had to brake with my left foot and accelerate with my right, but now the ESP handles that task . Unfortunately, left-foot braking was not possible in the TDI because the engine power is completely reduced when the brake pedal is pressed.

I'm slowly starting to get used to the electronics in my car. It just works a bit differently than in my fully mechanical rally car without any assistance.


Please do not attempt this in public road traffic under any circumstances... it is extremely dangerous.

And no, under normal driving conditions, I neither need ABS or ESP, nor do I drive in a way that would require them.
Just for emergency purposes, I want to know how it reacts and whether I can work with it, or if I'm just going to be a "passenger" in the car. I've now clarified this question for myself.

@Bertil:

Did you have Contiteves installed again, or did you get Bosch this time?

Good question. I haven't checked yet .
