If you press the accelerator normally, or heavy footed, the rpm shoots up and it again reaches 2700 rpm but for a smaller time and upshift. So all the same , except happens quickly. You hear that harsh engine noise. And it can go till 3000 also if you press it hard. I'll make a video tomorrow and post it.

Ok. I got the car back. This is what Skoda told There are no issues in the transmission or engine. Every thing is as expected. They said there is no clutch slippage. Every thing is normal. I'm disappointed.

Hope the clutch slip adjustments does not cause any shudders. 🙂 Any way, i'm asking the service guy and told him about TPI settings. He said he has adjusted and he will be share me the video. Expecting it . Will let you guys know.

Ok. I'm talking to service guys in parallel. Can this "clutch slip" issue be fixed without causing any other side effects ? Or i have to live with it ? @Roottoot As a workaround, i'm using the idea of shifting mode to Manual and upshifting. But if the issue can be fixed, then it is lot better.

@Roottoot And others. Here are the videos. Its worth 1000 words. Please comment. I see sluggishness every time even on moderate ramps with in city. And engine noise beyond 2500 rpm becomes very much louder. Moderate Uphill road: ( Its sluggish) https://drive.google.com/file/d/1J2ERgit9KdLVN14NtzAwivKtPnyLvHtv/view?usp=sharing On flat /horizontal road: ( No issues) https://drive.google.com/file/d/1L1U2Va6wATN3VNo8JKItULJ_1VF7_sa8/view?usp=drivesdk

- "I drove up a long slight hill at one point. Where the car would normally be in 6th gear at 50km/h it stayed in 4th for the entire time until it leveled off again." This is relatively better than the problem in 2/3 rd gears. Where the RPM revs up all the way to 2700 with moderate uphill. I'm wondering whether this is deliberately caliberated by Skoda/VW to put less stress on their DSG Gear box, that seems to be the weak link in the whole transmission chain. I wish i'm wrong here. Hope fully they rectify this in my car.

It doesn't. Yes Indian rules were lenient. Diesel Particulate Filter has been introduced now with all BS6 cars. And Adblue stuff. But those cars prices have been increased. So people are preferring petrol and the market is moving towards hybrids/plugin hybrids.

They said they are checking whether engine is generating enough torque. Also inspecting turbo. Also, once, emission control lamp, engine symbol, in cluster had lit. But after I power cycled it went away.

Thanks @Phil-E I have given it to Skoda service center. I will post the their justification here once I get it. Mine is a BS4 , same as Euro 4 car. No DPF in my car anyways. Makes sense, there could be 'n' number of parameters involved in upshifts. Have observed downhill, it uses engine braking.

May be acceleration is measured by accelerometer sensor and till the level is achieved it revs up and hold on to lower gears. Those request levels are mapped onto pedal. But wondering why we tend to upshift a manual car thinking it is appropriate.

Hmm. Ok. Thanks @Wino Its getting involved. Wondering why it needs so much power to climb in moderate uphill with just one person in car. Use to drive manual diesel 1.3 litre engine for couple of decades. Never revved it so hard to climb the hill, even under full load. Need to understand criteria for upshifts clearly. Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488

And fyi, the use case or issue is seen even with only driver in car with no load. And it's with in city limits not very steep up hill road.

Skoda rapid 1.5 diesel model is discontinued in India due to BS6 standards which took into effect from 2020 April. So, Skoda official website doesn't have this model. Sorry, I didn't find any official links.

The torque curve in 1.5TDI engine falls after 2500 rpm. As per their specification, it is 250 Nm between 1500 rpm till 2500 rpm. So no point in holding the gears past 2500 rpm expecting the car to accelerate. It won't. So, it makes sense to upshift so that rpm falls abruptly and expect for better acceleration. The Torque curve ( Torque vs RPM) is not linear.

1.5 TDI with 250 Nm torque is no less. DSG sw which decides about upshifting during uphill ascent seems to be the cause for this issue. Holding gears longer than necessary is irritating. I have raised this concern with Skoda.

@J.R. To over simplify the problem, imagine having just one gear in the car and a powerfull engine of 2 litre , this car can be defeated easily by 800 cc car with 5 speed transmission. We don't need that much of torque to carry 4 people uphill, it should upshift.

@Rootoot Yes, it's the same rapid. Its launched 4 years back. I purchased this model so that all the issues in dsg transmission would have been fixed and will be well tested. @J.R. Definitely, if acceleration / throttle position only thing that is used, then during uphill ascents , it revvs higher. They should have had a different torque curves uphill. So that it shifts aptly and not rev hard. The same rapid with manual gearbox is quicker than dsg variant during uphill. Delayed upshifts will make the car travel slower.

I own a Skoda Rapid Diesel Automatic, 2019 model. It has DQ200 Gearbox. I'm facing the below issue, any suggestions are welcome. Issue: It seems the gear shift behaviour is different in Flat roads and bit uphill roads (even moderately uphill, in city conditions) . Gearbox holds on to the lower gears little longer than on flat surface. Mine is a brand new car which is just 7 months old and i see it during uphill ascent. For instance, It spends close to 2500rpm in 2 gear and then it shifts to 3 gear, this is with just the driver and no other load in the car. And the speedometer is around 35 to 40 Kmph. I'm seeing such a behavior even in 3 gear as well. So it seems "upshifts" are sluggish. The engine roars and it is audible inside the cabin. This is annoying and to get rid of it, as a workaround, i change to tiptronic mode and upshift. Why is this behavior seen in DSG variant ? Is it related to "inclination sensor" calibration issue ? I have also tried to lift off my foot momentarily from accelerator after it leaches 2500 rpm, but it never upshifts. Seems the thresholds for upshift during uphills is not properly calibrated. Actually, it's 7 speed dry clutch dq200 gearbox. Its 1.5 tdi . 2019 variant. Now the problem statement is : "Why can't they have same behaviour as on flat roads nice and quick ?" Its D mode by the way. Not sports mode. I dont see any point in holding the gears and revving the engine up and delaying upshifts. Seems it is holding the torque which we are not requesting for . Like i try to lift off my foot from accelerator momentarily after it reaches a roaring rpm of 2500rpm in 2 gear, but it never up****s.

When the engine rpm begins to increase beyond 2500 rpm in 2 gear means that it's time to upshift, what's the point in revving high and allowing to increase without upshift, because rpm will only increase if load is compensated. I put to tiptronic mode and upshift as a work around. May be simple sensor inclination calibration issue ?

Actually, it's 7 speed dry clutch dq200 gearbox. Its 1.5 tdi . 2019 variant. Issue is, the gearshifts during uphill ascent is sluggish, than compared to horizontal roads. And I hear engine roaring and it's annoying. Now the problem statement is : "Why can't they have same behaviour as on flat roads Nice and quick. ?" Its D mode by the way. Not sports mode.

I own a Skoda Rapid Diesel Automatic, 2019 model. It has DQ200 Gearbox. I also see the exact same issue. Seems the gear shift behaviour is different in Flat roads and bit uphill roads. Gearbox holds on to the lower gears little longer than on flat surface. Mine is a brand new car which is just 7 months old and i see exact same behavior. And it is always seen during uphill. It spends close to 2500rpm in 2 gear and then it shifts to 3 gear. This is with just the driver and no other load in the car. And the speedometer is around 35 to 40 Kmph. I'm seeing such a behavior even in 3 gear as well. So it seems "upshifts" are sluggish.
