Update to 8500KMS
So far so good except a few oncoming show stoppers.
Bad things...
1. AC making lots of noise, which we believe is the condensor fan going kaput ( god, what would have happened if hadnt taken extended wrnty

)
2. EGR modulator needs a HARD relook, and am going to be present throughout in front of the vehicle during the 2nd service..
(please tell me is it a switch (bosh or padmini make) or its a big cylindrical thing with a pipe connecting to the padmini/bosh switch)
3. some sort of a minor leakage happening from where the sensor os coolent temperature sensor .. lot of dust accumulated there.
Good things..
1. lesser smoke now from before, i filled normal diesel only and the observation is based on 2 tankfulls. I also observed that the smoke which was present during the night time against other vehicles light has become lesser. may be a good cleanup of the catcon and egr is required.
2. milege seems to be never going below or above 11.5 nowdays, with or without a/c
3. Lesser vibrations from before and i feel it will improve after 10K servicing.
well so long, will update this thread with my second service details soon.
