Updating this thread after quite a gap. My car has now done 13k km and well, Nothing's majorly changed. I still haven't got any Steering Rattle (touch wood) but the engine noise at cold starts has slightly increased albeit a very small increase.
Mileage figures have improved after the second service and oil change. I am getting 12.5 kmpl as compared to 11.8 i used to get before in city and with a heavy foot.
One strange thing i have noticed, There is a drastic difference in FE figures if i fill at other fuel stations. I generally make it a point to fill at only IOC bunks. But i have had to fill at HP pumps 3 times in the 13k kilometers coz the fuel level was too low to take it to the next IOC pump.There is a drop of 1kmpl every single time!
I think i have got used to the Turbo lag so much that i don't really notice it kicking in these days at all

I don't know if the lag has reduced after the service (I am not technically good enough to comment on it anyway) or i am just too used to it and shift better.
Did a Bangalore - Davangere around a month back. I still love it so much on the Highways. Pulls so neat and clean. Am doing a Bangalore - Shimoga tomorrow morning, Will update with the mileage figures once i am back.
Some random pics.
Hyundai people had called me up for rating the service. I rated 2 parameters a 8 on 10. (Delay and the wash). Delay coz they made me wait for close to an hour and half more than what they had promised for and the wash coz they had put the polish on the door pads which made the beige color look dirty (The polish was actually for the arm rest on the doors. But they had by mistake touched the beige part as well). I just thought it was a customary review and nothing too serious.
Someone from Hyundai calls me in the next 10 minutes and asks me for an appointment so that they can come and wash the car at my place.

I was really impressed!
I really did not know the rating i give actually affects my SA as well. He calls me in the evening and says "Sir, why did you give that rating! I would solved you all your problems and given you a free wash anytime you wanted". I apologized to him and asked him to tell the Hyundai guys to call me again. Gave a 9 rating the second time. I really like my SA, he is a very nice and honest guy. Did not want him to be disappointed.
All this coz of Hyundai's horrible rating scale. They have 1 - 8 as bad. 9 good. 10 Excellent. Where is Average ?? Why would they need 8 levels for bad. Beats me!
I ordered and got a ELM327 bluetooth scanner for 20 dollars (Check OBD thread for the link). Worked fine for 3 days and then stopped working. I met other BHPian's Salbin and White-Rabbit around 2 weeks back. They wanted to try out the scanner on there Beat. I plugged out the scanner from my car's OBD port and plugged it on the beat, It stops working! No more recognized by my phone. I think i removed it from the slot when the car was on. So not really sure if that caused the problem. I mailed the people whom i ordered from that i have a problem with it, they asked me for the pics, I promptly mailed them the pics and guess what, they are ready to replace it with a new one for me. (Just that i have to ship the old one to Hong kong and i know it'll cost me a bomb). Haven't mailed them back, will do tomorrow telling them that it'll cost me more to ship than the product itself and asking them for an alternative.
For the time it was working, it worked like a charm without any problem.
I have also ordered for the L-shaped Merc type DRL's. Haven't got them as yet. Will update once i get it. Cheers!
