Hi, I do a lot of driving in traffic so the Traffic Jam Assist function has always appealed.
I thought Traffic Jam Assist in the Golf was just ACC and Lane Assist working in tandem to brake/accelerate and steer.
The GTI now comes with Lane Assist as well as ACC in the standard spec. So does this give me Traffic Jam Assist?
The configurator doesn't list explicitly in the standard spec sheet. However it does list Traffic Jam Assist explicitly in the now cheaper Lane Assist Plus option.
What's confusing me is that I can't see what's in Lane Assist Plus over the free Lane Assist that would give me this function.
The configurator doesn't give much info and isn't very helpful.
Does anyone know if I have to spec the Lane Assist Plus to get this?
Thanks

According to page 43 of the latest price list brochure, the Dynamic Light Assist option available on the GTI, GTD, GTE Advance and R models gives you Traffic Jam Assist. Link to brochure below;

-
Thanks, but page 40 shows you get Dynamic Light assist as standard. It just doesn't mention traffic jam assist. Maybe the they've just disabled it unless you stump up for the lane assist plus.

Thanks, very helpful. I'm guessing the traffic jam assist listed as an option then is the v1.5. Not sure that's worth the extra money though so will stick with the standard.

Plus has the 'side scan' for lane changing and blind spot etc

Nope.
On the GTE/GTD/GTI/R 'Traffic Jam Assist' is not standard, it is only available as part of the 'Plus' pack which gives you:
- Dynamic Light Assist
- Emergency Assist
- Rear Traffic Alert
- Side scan
- Traffic Jam Assist
- Traffic Sign Recognition
The pack is £575 and is available on DSG models only.
-
My March 2019 GTI has the following and I didn’t spec them as extras:
- Dynamic Light Assist YES
- Emergency Assist YES
- Rear Traffic Alert NO
- Side scan NO
- Traffic Jam Assist YES
- Traffic Sign Recognition YES
I also find VWs spec list utterly bewildering. Audi’s configurator is far easier to understand. Having said that, everything is a £1000 optional extra with Audi 🤣

Your MY19 doesn't have Traffic Jam Assist, it has as standard (free) a pack consisting of;
Lane Assist
Dynamic Light Assist
Traffic Sign Recognition.
From MY19 (build week 51 onwards) the pack became standard (free) on the GTE/GTD/GTI/R, all other Golf models it's an option and costs £650.
The 'plus' pack adds Traffic Jam Assist and Side Assist, the 'plus' pack is £575 for the GTE/GTD/GTI/R.
There are two other packs available for the Golf, at £1120 and £1225, but they aren't available or applicable to the GTE/GTD/GTI/R.

Ok, but presumably if you have ACC switched on and come to a full stop, start/stop stops the engine then when the car in front pulls away it starts it again (without taking your foot off the brake pedal) and then (I’m assuming) it would engage ACC and crawl forward. So how is this different to Traffic Jam Assist? Or doesn’t ACC work below a certain speed.
On a similar note I’m considering switching off Lane Assist. I drove around a car which was in the centre of the road and turning right, and the car tried to correct me but merely pointed me straight at the turning car again. Slightly disconcerting. Yes I know I could have indicated left but then cars coming from the left hand junction would have thought I was turning left as opposed to going around the car that was turning off.
It’s all clever tech but not really necessary. It’s just refining driverless car technologies in real world usage scenarios.

ACC works in conjunction with stop/start, but once the car has been brought to a halt by the system, you need to touch the accelerator again to move off. Lane Assist also only works at speeds over 40mph.
Traffic Jam Assist adds to both the ACC function and Lane Assist function, by allowing LA and ACC to work together in slow moving traffic (hence the name). With TJA you can sit stationary for 10-15secs before the car applies the brake.
-
Yeah TJA will steer (using lane assist) and stop/go under 35mph.... with lots of caveats of course!
-
is it possible to have TJA retrofitted on a MY19?
I picked mine up Saturday, it was a bit of an impulse buy (I was planning on waiting another 6-12mo) but given the 10% brexit increase and the current deals from VW I had my arm twisted whilst my Polo BlueGT was in for its MOT!

Without going all political - there is no current 10% ‘Brexit increase’. It’s been delayed and there’s a reasonable chance it may never happen. The 10% only comes into play if there’s no deal (which Parliament have already rejected) and if we impose the 10% tariff on car imports - the government has indicated 95% of goods where tariffs would apply will be set to 0% in the event of no deal - even if the EU doesn’t reciprocate. In short, don’t worry about the ten percent because it’s about as likely as seeing the Mk8 being released next week. Otherwise - enjoy your car. Great choice.
-

I don't think so.
Assuming that you already have lane assist then you probably have the hardware, its the software component you need, but its not one of the things that has dealer activation possible (like voice control or AppConnect).
Technically possible, likely, I'd say no.

Well that’s good to know for the future - I’m not all that clued up on politics but had read it was a possible scenario. I think I was subconsciously looking for excuses for why I brought my old car in for an MOT and came out with a new Golf GTI :grin:

you sure, if you got a wise dealer they may do it for you, I think you’ll find it’ll cost about £300, or if you know someone with VCP then they can flash the firmware to have it (I say flash the firmware as it’s not a vcds/obdeleven mod as it goes deaper than they can)
-
Yes of course you could load firmware... but I seem to remember VW have all sorts of protection on that that needs VW factory authorisation codes to be generated (keying the software to your car's serial number) and VW themselves have a policy of not providing that for any vehicles that weren't shipped from the factory with feature sets enabled...

This is for Audi but it has been done in a golf.

i don’t mean load a firmware but load a parameter into the firmware with vcp, it’s been done all over the world with no problems, just didnt wanna go into it more on here,
Not sure that TJA works, I can’t try as I already have it in mine

Interesting...

Well my May 2018 GTI was specced with:
Lane Assist Plus with Dynamic Light Assist, Emergency Assist, Rear Traffic Alert, Side Scan, Traffic Jam Assist and Traffic Sign Recognition
Which apparently consists of:
Lane Assist, camera controlled warning system should the vehicle drift out of its lane.
Dynamic Light Assist, automatic sensors detect other road users and cover part of
the headlights appropriately. If dazzling other road users cannot be prevented, the
light distribution is automatically set to dipped beam headlights.
Emergency Assist, driver intervention should sensors detect the driver is incapable of
driving. Automatic hazard light activation while bringing the vehicle to a controlled
stop within its lane
Rear Traffic Alert, monitors the area behind the vehicle during reversing manoeuvres,
if another vehicle is getting too close the system alerts the driver by means of an
audible and visual warning or brake intervention where a collision is imminent.
Side scan, radar sensor controlled warning system for lane changing and blind spots
with visual warning via light in door mirror housing.
Traffic Jam Assist, camera and radar sensor controlled warning system to accelerate,
brake and steer should the vehicle drift out of its lane, providing the driver’s hands
are on the wheel.
Traffic Sign Recognition, camera controlled system with visual warning for traffic
and road signs.
But despite that, I've never been able to work out how traffic assist works (or is even installed) !

Sooty:
Traffic Jam Assist function
At speeds under 60 km/h (35 mph) Traffic Jam Assist can maintain a time interval, set by the driver, to a vehicle in front, and help the vehicle to stay in lane ⇒ .
The system automatically controls acceleration, braking, steering and, if required, will decelerate to a stop behind a vehicle that is stopping, and then drive away again automatically.
Only use Traffic Jam Assist on motorways and well-maintained country roads. Do not use Traffic Jam Assist in urban traffic.
Switching Traffic Jam Assist on and off
Traffic Jam Assist together with the adaptive lane guidance ⇒ Lane keeping system (Lane Assist) is switched on and off via the Infotainment system ⇒ Operation and display in Infotainment system .
Traffic Jam Assist can also be switched off together with the lane keeping system by pressing the button for driver assist systems ⇒ Button for driver assist systems .
Technical requirements for using Traffic Jam Assist
The lane keeping system is switched on and active together with the adaptive lane guidance ⇒ Lane keeping system (Lane Assist) .
Adaptive Cruise Control (ACC) is switched on and active ⇒ Adaptive Cruise Control .
The selector lever is in position D/S or in the Tiptronic gate.
The system has detected a lane marking on both the right and left sides of the vehicle ⇒ Fig. 134 .
The speed is under 60 km/h (35 mph).
Traffic Jam Assist is not active (the indicator lamp for the lane keeping system lights up yellow)
As soon as one of the conditions indicated on ⇒ Technical requirements for using Traffic Jam Assist is no longer fulfilled.
If one of the conditions for the proper functioning of the lane keeping system is no longer fulfilled ⇒ Lane keeping system (Lane Assist) .
If one of the conditions for the Adaptive Cruise Control (ACC) is no longer fulfilled ⇒ Adaptive Cruise Control .
Switch off Traffic Jam Assist in the following situations
Traffic Jam Assist should always be switched off in the following situations due to system limitations:
When a high level of concentration is required by the driver.
Very sporty driving.
In poor weather conditions, e.g. snow or heavy rain.
Poor road conditions.
Driving through road works. (hmmm where will most jams occur VW!?)
In urban areas.

Fred I think you’ll find it’s more to do with the lines not to good in roadworks

Yes, I know...
The ACC bit of the manual says don't use it in roadworks too :D
-
I was all excited reading the spec sheet and the abilities of ACC before delivery. In the real world most of this stuff is just a pain in the a$$. I almost had a collision trying to fathom out how to switch on ACC and taking my eyes off the road trying to work out which buttons to press. Once it was finally on, I decided after about 3 minutes I hated the juddery way that it reduces speed to match the traffic in front and switched it off again.
When driving manually I anticipate the road ahead and just lift off the throttle. I rarely need to use my brakes during normal A/B road driving. I’m not sure if it applies the brakes or slows by changing gear? Doesn’t feel particularly smooth and I imagine I’d look like one of those old fools who dab the brake pedal every 13 seconds from the car behind. Anyway, switched it off and haven’t used it since.
Dynamic Headlights however - worth every single penny. Had High Beam Assist on the Audi but this is a whole new level.
-
I love ACC!
Wouldn't be without it... no idea why you say its juddery? But then again I have a manual gearbox.
Easy to switch on, easy to adjust, works really well and reduces stress for me loads. One of the best things on the Mk7 for me!
-
Cruise Control on a manual is even more pointless! :grin:

When doing say 50mph and the car in front brakes, there’s a sensation similar to (but not as noticeable as) when ABS kicks in. It feels like it’s dabbing the brakes rapidly and gently to slow down. Maybe because it’s automated rather than me doing it, but it’s not as smooth as my driving. I didn’t like it.
-

Absolutely not. Works just lovely on all of those motorway miles I do.... then again I have a GTD and its happy to pick up from 30mph in 6th gear.

Bizarre. Are you sure that you haven't broken something?
-
Don’t think so. My description is exaggerated I’m sure others with DSG/ACC will know what I mean?

Nope, mines smooth as silk when braking and accelerating. I’ve had ACC on my last three cars and I simply wouldn’t be without it. One of the reasons for me not selecting a m140i was the lack of ACC, it’s not even an option.
It’s essential for the motorway driving I do (especially on smart motorways) and really handy/useful when cruising through 30/40/50 zones. The ability to knock the speed up/down in 5mph increments with just a touch of a button is also brilliant as you adjust though the speed zones.
Another good thing about ACC is when you have the ‘driver assistance’ screen up in the middle of the cockpit it shows what the cars around you are doing in all there lanes.
-
Didn’t realise this. I’ve been driving with the map in the middle as the other screens didn’t really make much use of the space or show anything that wasn’t on display elsewhere. I’ll try ACC again tomorrow for a second opinion! If I can remember how to activate it lol.
-

I am with kmpowell on this one, my ACC is silky smooth and I use it 90% of the time behind the wheel due to my commutes. Have you tried switching it between Eco, Normal and Sport to see if the jerkiness is there in all modes? If you stick your car in individual mode it will be easier to just change the ACC setting for comparison.
-
If I can remember how to activate it lol.
You just press the "set" button on the steering wheel when you are at the speed you want to cruise at. :huh:
Providing the car is set for ACC rather than speed limiter (use the "mode" switch to choose), the ACC will activate when you press that button. To cancel it you simply dab the brake and/or let the car come to a halt. If you want to carry on using the ACC again, simply press the "RES" button.To set your desired max speed press the silver rocker/toggle left to go down in increments of 5MPH and right to go up in increments of 5MPH, press the button in the middle of the silver rocker/toggle to set the max.min distance you are comfortable with.
All the ACC controls are in that little cluster on your steering wheel, it really is simply to use. If you're unsure on how it works, I'd advise RTFM before heading out as you don't want to bend your car.
-
Hmm think I might have messed something up. It just kept saying ACC Deactivated regardless what I pressed. It was ticked in the settings menu. I’ll try it again tomorrow. Probably just needed switching off and on again.
-
I'd probably not recommend ACC on a twisty B road though.... it of course will either run at the speed that you set or the lower speed of the car in front.... some bends can be "interesting" when it ploughs straight through them on ACC, even if the speed is not too much for the bend, the way it enters the bend on the throttle can be alarming!
On motorways and dual carriageways and decent A roads, I have it on maybe most of the time.
With DSG it will be even better because it will go all the way down to a stop and then start off again... on manual, it won't - you get a "apply brakes" message and have to intervene, but that's ok for me for now.
-
Tried it this morning on the A road - and it worked really well. I didn’t touch the brake or accelerator for 17 miles which included two roundabouts! Rather impressive. Last time I tried it was a B road so maybe that explained the juddery braking experience. Not something I’ll use much on my daily routes though. I prefer being in control and dual carriageways are rarer than rocking horse $h1t around here.
-
I prefer being in control
I used to think that, but that will fade in time if you persevere. The more you use it and get a sense of your own personal preference distance/speed settings, the more it'll become second nature when you are on long A-Roads, Duals and Motorways. It's about having trust in the systems, and once you have that trust your thinking that you aren't in full control goes away. Remember, you are still in full control because your feet and fingers control how the ACC is set, so you can override/cancel/adapt/change it any any point of the journey, and the Golf's warning systems will alert you if you need to take drastic action because of somebody else.
ACC with the DSG is sublime IMO, the double clutch system makes it so smooth. :)
