The 6% better efficiency is not just because of Dry vs Wet, but because 7 gears are more optimized compared to 6, the Dry clutch does add some efficiency over the Wet but it's less than 6%, maybe 4%-5%. The extra 7th gear improves acceleration because each gear range are shorter so the car can accelerate better, but makes little difference in start/stop driving. The reason manufacturers went for Dry is because efficiency (which result in less power loss & better fuel consumption), and 2: Less stringent requirement for sealing to prevent oil leak in wet clutch thus cheaper & also allowing manufacturers to claim it's maintenance free since you don't need to change the oil.

However comparing Dry & Wet, the difference in terms of performance is really negligible unless you are racing in the circuit, for most people a 0.5s difference means nothing other than shiok sendiri. Like it matters 99% of the time people drive.

Even comparing Auto vs DSG it's not that significant compared to the production cost & maintenance+repair cost. That is why Manufacturers who emphasize on reliability like Toyota & Honda don't really focus on them. For European cars that emphasize on performance & the fact that long lasting isn't their main concern allows them to use all the advance technology available. That is why people consider european cars more advanced. Just like performance tyre vs normal tyre, there's no such thing as both performance & endurance.

DSG has been around very long time, Audi was the earliest to implement it. Most people know how expensive it is to fix DSG, even Proton Savvy uses the SSG (AMT they call it), and guess what, the gear cost more than the car today. Impressive it is, the reliability is still a big question mark even after more than a decade on commercial vehicles. At least for high powered cars with Auto Transmission, aggressive driving doesn't wear the gear down as much as DSG. Yet i don't know why for non performance car they chose DSG over more economically sound Automatics where cost is a concern for both buyer & manufacturers.

Also don't forget, Single or Dual Clutch, the computerized gear will grab & let go of the clutch when the gear is engaged, unlike Manual Clutch where the driver can balance out the grip of the clutch depending on the speed. Imagine letting go of the clutch pedal immediately after downshift under city drive, it won't just make the car jerk but also put stress on the gear & also other parts like driveshaft & engine. For DSG the computer doesn't car about the Clutch.

Actually most of the European manufacturers have to adhere to a lot of emissions standards in the UK as well hence the push towards technologies that increase efficiency and reduce overall emission rates. Based on the report I posted in the link, the main conclusion that with the use of the DSG gearboxes over the conventional 6-speed automatic that they used to use, their overall emissions are reduced, not from just the driving perspective but in terms of manufacturing of the gearboxes, servicing and recycling.

In terms of performance, it makes a difference for enthusiasts because of the limiting torque factor of the DQ200 gearbox thanks to it's 250Nm limitation. Not even in terms of performance junkies but also to the European market who favours diesel powered cars/4WD, they can't alone rely on the DQ200. Hence a lot of speed enthusiasts, if they can afford it will go for the more performance ready DQ250 and the DQ500. But for the everyday, point A to point B drivers, the DQ200 will serve them just fine.

But again, I think we have diverged very far away from the main point which was the question, "Is the 7-speeder gearbox problematic".

Do anyone knows is 18" for GOLF mk7 TSI suitabe?

So does the new mk7 GTI comes with the soundaktor which they put on the mk6 to give some fake engine sound to make the driver feel good?

hi sifu, i will be getting my beetle 1.2 this coming thursday...this is the first time i buy car, so before i sign anything should i check the car? which part have to take more concern? such as mile range?

No issues with it when I was using 18" rims on my Golf Mk6 TSI. As long as the rim isn't heavy

Check thoroughly, watch out for scratches, dents, scuffs on the rims, check all indicators, electronic switches, windscreen wiper, mileage and the interior if there is any damage. Other than those, can't think of anything else.

for mileage more than how much consider too much?

Anything more than 100km I would be suspect and should check with them why is the mileage that much.

ok tks...

Usually how much the mileage?

ha...i have no idea...from my previous experience my dad buy car he never check anything of the car b4 sign any document...as you know uncle mindset, we cant brain...lol

should immediately ask the SA if found the mileage above 100km

Yes but only rear part as you do not have front sensors;

If you want to contact FA Wagen VW Glenmarie new service centre: 0355670698, just FYI.

Hie guys , just wanna ask regarding my

Golf GTI: is it normal for the car to have squeaking sound from the doors after about 1 year driving it?

POLO Tsi: my car had the usual clutch slip problem. So sent to VW SC to replace the clutch pack. Everything was ok till recently, whenever i go low speed, say around 20-30kmh i can hear some metal sound from below the car. This only happens at low speed. But at higher speeds, thr issint any sound.

Is it the gearbox problem?

Tq sifus!

VW service damn f*cked up. Last week sent in, next week only can collect.

more than 1 week to service 1 car? that is hideous

How much is the maintenance for a VW Golf 1.4 Tsi?

i've tested the vw passat and the mark 7 golf tsi way back in april. i personally felt the passat was nicer to drive than the golf but don't get me wrong. the golf was good enough. last sunday i've tested the recently launched mark 7 gti. The car's performance was bullet enough eventhough some of it's rivals offer slightly more horsepower and the handling was brilliant but not as sensational as the bimmer. well, rwd cannot beat the fwd or awd in terms of sheer sensation. but one thing i've noticed was it's not as refine as the tsi in terms of NVH. The sound insulation is poorer than the tsi or passat. The engine sounds rough and feels rough at low rpm but once the soundaktor activate at 3+++rpm i think, it sounds quite good with the pop exhaust sound when upshifting. The strange thing was that the gti sounds even poorer than the toyota or honda NA engine at low rpm but not in the case of the tsi or the passat. But the main that i'm gonna highlight is about the dsg in the gti. When in the passat or the golf tsi that using the 7speed dry clutch, there was literally no vibration when in D or R on idling. It's like the same vibration-free that u feel when in N. But in the gti which use the 6speed wet clutch, the vibration can be felt. i thought only the japanese car got vibration. This is the the 1st german car that i felt it. Quite frustated actualy. In overall, the gti is a great rounded car but the pricing is ridiculous. Not getting a sunroof, smart entry, lether seat, navigation, DCC on 218k price tag. phewww

Yeah! Fixing the coolant leak. From Monday they keep telling me installing the part, today I go, part just arrived. Wtf have to wait till next week only can collect. Now no car! WADDAFARK!!!
