In fact the same is enough even in second gear from a standstill.

The MPI is a different ballgame.

Infact for TDI, I face the rubberband effect i.e. as soon as I let go of the Clutch, the car is ready to shoot forward. Becomes a bit difficult during bumper to bumper traffic especially with the long play of clutch.

Have faced no such problem on TDI. As for the cold engine, I try running the engine for a minute to let is get warm. Since the car is not equipped with Heat Gauge, I monitor the temperature via the OBD Scanner to make sure the engine is warmed a bit before I move on.

1.6 TDi torque : 250 Nm @ 1500-2500 rpm
1.6 MPi torque : 153 Nm @ 3800 rpm

A slight tap on accelerator of TDi would have rpm at 1500+ and 250 Nm torque would pull up weight easily. Now MPi unit with 153 Nm @ 3800 rpm would require a lot more rev to make it up steep climb. Any day TDi would be more easier to drive in & around city and on highway would be more fun than MPi.

Thanks. This sounds to me the most suitable explanation.
OT: How often do we make it to 3800RPM. I barely go beyond 2500RPM mark, let alone crossing 3500

Can you share with us the time/distance vs the temperature plot, if at all you have some random/daily readings. Would benefit those who don't have the scanner.

@ninjatalli- In my case some electricals started failing e.g. power windows not rolling up. And starts were troublesome which has never happened in this car. Took it to VW and they confirmed battery needed a change. Had it replaced outside with a 55V Exide battery for approx 6k.

Noopster has very much explained scenarios which happens when battery starts becoming weak. I would only like to add to it, get an Amaron battery. Exide isn't any good and I wouldn't touch it with a barge pole.

Wouldn't it reset the ECU and other settings? Did you go back to the workshop get all those settings fixed?

I will try plotting the Time v/s Temp graph tomorrow morning but not sure if this will help much.
The car can trouble X kms of Distance in Y mins of time while reaching an optimum temp.
Usually it takes 4-5kms on a plain run in a time span of around 10-15 mins to reach it.

Even I think my car's battery has started giving signals of going week. First time when I start the car, it takes some extra time to start and the starting noise is different. Rest everything is working fine. Any ideas how much does the service center charge to change it and for how much we can get an Amaron outside. Any specifications for the battery will be helpful too.

I think maybe its due to cold weather in Gurgaon. Normally in colder conditions it takes more time for engine to crank up. Also the sound would be different as there would be more typical harsher tractor like noise from 1.6 TDi. I would suggest you to wait a bit longer till car shows sign of weak battery as put forth by Noopster such as electricals started failing e.g. power windows not rolling up.

My other car Ford Fiesta 1.4 TDCi these days takes a lot more time(5 sec more) to start in colder Mumbai weather and sometimes do feel it may just be about to give away. Still running strong. I belive Gurgaon would be even more chilly.

Vento 1.6 TDi battery has a capacity of 60 Ah whereas for 1.6 MPi its 45 Ah. So battery would costlier for 1.6 TDi in comparison to petrol counterpart. You can have a look at the following BatteryBhai.com website. Its has all the battery info with prices including discount and also on return of older battery.

Batterybhai.com

Also there are 3 Amaron stores in Gurgaon which would give you info as well.

Amaron Pit Stop Locator

No idea about, whether service center are equipped with spare battery for sale to customers.

Hi, I had put this earlier on the Jetta thread but seems nobody has faced a similar issue there. Hence putting it again in the Polo and Vento thread. Hope thats ok with the moderators.
Does anybody here have the Nippon NAL NAV9180 HU installed. The HU is the same that used to come with the Vento IPL edition.
I'm having some problem using the BT on the unit. I earlier had a blabkberry and was working absolutely fine. However, I just bought an iphone, and there seems to be some compatibility issue here. It connects alright, but whenever I receive a call, it just keeps playing the ring tone - even after the call has been disconnected. The only way to stop that is to either switch of the HU or disconnect the BT connection
Has anybody else faced a similar problem

[Vikas Arora]

@Gurgaonites, has anyone tried VW Dhingra's service center? Is it better than Frontier or should i just stick to Frontier? My TDI's second service is due and I still haven't decided between the two. Though there is nothing great about Frontier - my last visit to them (about an year ago) was just ok.

Any references at Dhingra/Frontier would also help. My major concerns this time are 'tak-tak' noise in steering and i think the fuel pump has suddenly started humming a bit in the mornings.

As you have mentioned that Blackberry was working fine, I believe it may be software issue with iPhone. Since new iPhone comes with iOS 7 because of which Nippon NAL NAV9180 maybe having compatibility issue. Its definitely be a software issue rather than hardware.

Try searching if you could find a firmware/software upgrade for Nippon NAL NAV9180 for supporting newer operating system.

Finally I went to VW Frontier for the second service. Total amount was about Rs 11700/- (bills attached) and out of this roughly Rs 1400/- was for alignment/balancing/rotation. I was forced to get this done at the dealer since the regular tyre shop that i visit was unable to adjust the camber. Anyhow this amount is on the higher side but this time it was well spent. Alignment/balancing seems to be perfect this time.

I had complained about excessive vibrations and some tak-tak noise from the steering. SA informed me that they carried out a thorough check and discovered that engine/gear-box mounts were worn out - these were replaced under warranty. I think replacement of mounts has made a huge difference in the drive and my Vento was never as smooth as it is now. There is a huge difference in the overall noise inside the cabin.

I also happened to go through the internal file where all the diagnostic reports are stored and the VAS reports were all clean i:e without any errors. No SW update was required. Though it seems that the battery would run for few months only, VAS report showed that the battery is almost at the end of its life (barely in the healthy zone).

Overall experience was much better than the last 2 visits and these guys have improved a lot. Secondly, agency must have worked hard to retain the employees - i could see a lot of familiar faces (mechanics/supervisors/SAs) as compared to last year.

Engine/ gear box mounts worn out ??? How many kms your car has run??. These things are not supposed to wear out so fast even if they were replaced under warranty. What about the famed german quality and engineering.

My Baleno's mounts are still going strong at 8 yrs/1.2 lac kms.

Well I also asked the same question from SA. I think VW already knew about the problems with mounts and they chose not to change those on Ventos manufactured from 2012 (mine is may 2012 manufactured). However, they did replace mounts voluntarily on the older models.

Anyways I am happy that they took my complaint seriously and replaced the mounts. But a bigger question still remains - for how long would the current ones continue before giving up.

[MADMAX111]

It would be interesting to know as to who are the vendors for the VAG group for rubber/other parts. Most of the parts to Jap/Korean car makers in India are supplied by Indian vendors. If they can produce high quality stuff (read relaible/long life/maintenance free) for Jap car makers, then what prevents VAG group from getting the same quality from them.

just my 2 cents
