Usually happens in 4th and 5th. On the highway this happens when one is crossing the 70Kmph region in 5th gear.

Actually i am sure it happens when in 4th gear and subsides when i downshift to 3rd. You are right, the vibration comes from the roof mounted AC sometimes. Can we do something to dampen it?

Another issue - AC Fuse
My 2.2 is Apr 08 model, Last 2 months i have changed one 20A fuse and one 25 A fuse. The AC compressor was cut off because of these fuses. Is anything wrong with my AC or can i consider as normal wear and tear on the electrical system?

Ac fuse needs to be replaced by a 30amp fuse and your problem will be solved permanently. This was done on my Safari - Apr 08 too inspite of no fuse failure.

i get floor vibration and a typical resonance noise of body or differential drive in city drive. its more persistant while shifting gear from 2 to 3, prominant when sitting in the middle /rear seats. this occurs when rpm is around 2000 or less mark. i have experianced it more in city drives.

One more thing driver and front seaters does not feel this noise.
Is this normal ?
what is the ideal gear shift rpms 2 to 3rd and 3rd to 4th.

ideal rpm for gear shifting is 2500 rpm to guarantee no vibrations.
Guys, this is a diesel and cannot be driven like a petrol. Shifting at 2000rpm is likely to cause shudder, judder, vibrations, etc.
There is nothing wrong your vehicle. Just drive it the way it should be.

I think this maybe equivalent to kicking the can further down the road. If the fuse keeps blowing it is because of a potential issue in the AC electricals. The idea of having the fuse blow is so that the electrical component itself doesn't get damaged. A higher amp fuse will eventually cause the the defective electrical part to fail/short eventually and if you are lucky it will still be within the warranty period.

When I had my M-Class I had a similar issue. There are two auxiliary fans in front of the radiator to cool the AC condensor. Once I was parked outside waiting in the car for somebody on an extremely hot day and noticed that the AC wasn't upto the mark even at full fan speed and max cold on the thermostat. So I went outside and noticed the auxilliary fans were not working. I complained about this in my next service and they replaced the fuse. This happened on a couple of other locations so I just kept replacing the fuse.

After my warranty expired I noticed that the fan stopped working and changing the fuse didn't help. When I gave it to the dealer for my next service, I mentioned this. Service adviser called me later that day and told me that the wiring harness had a short and was burned out and had to be replaced and I would have to pay for it since the car was not under warranty any more. I hung up, went to the dealership and went ape-**** on this guy. I told him that I had brought up the fuse blowing issue at every service and they just kept putting in new fuses. Since I had a complete service history at the dealer they finally offered to cover the cost even though my car was no longer under warranty.

Thanks for the sensible advice. I however, will try my odds with the fuse. One thing i apply to most situations in life and it has worked for me> The more you investigate and fidgit, the worse it gets. Just leave it alone as long as its not critical or bothering to inconvenience. Might not work with everyone, but im different.

Im sure they did not give you 4 yrs warranty for your M class. Id prefer using mine to the fullest as and when required rather than geting paranoid about stuff that isnt bothering me yet.

I have a gut feeling that this Safari is an alphonso, just like adc's. :D

OK, Jay, here is where I tend to agree fully! :)
I'd posted this on the Scorpio thread just a few days ago:

And, very importantly, I am strongly against having things 'touched' in my car. I like 'stock' and will bear minor issues as long as the grease monkeys at the authorized service centres do not get their hands on my car!

Ah ha, so now the comparison base starts with exotic fruits.

But why are you doing this to the VTT, it sure will take the stress now but it will show up at a later stage.

No way one can use the mineral oil for 15k km, more so after all the rough driving that yours and mine VTTs are subjected to. I change oil every 6-7k but use then synthetic oil if you go for the 15k interval - even what I gather from this forum is max 10k interval is to be used for synthetic oil.

I am not in the habit of looking under the bonnet. I did not even take my Safari to the TASS for a check up before my Spiti trip.
It has never had me stranded anywhere.
I honestly do not think twice before before cranking the engine.
After the 15000kms service at Mandi, I decided not to change engine oil till 30000kms(scheduled service). Just to see how the car performs under extreme stress that I give it.
I have recently returned from a 5000kms journey to nowhere and back(please wait till I find time for the travelogue) which included hard driving at 160kph and revving through all gears and also included approx 90kms of total 4wd offroad.
The odometer now reads around 27900kms.
I have seen the service light come on recently while revving and coasting on all gears. It however does not scare me, since im sure it must be sedimenter related, terribly messed up air filter, poor fuel quality and /or engine oil devoid of its properties.
I do intend to get these sorted out at the 30000kms service and im confident the TASS will sort it.

I agree, the mentioned vibrations/booming noise is more to do with your style of driving.
Also, even if one continues driving they way one does, this gets reduced as the SUV is driven around.

2000 is good enough. I think one can cut down a couple hundred rpms too. But, I want my boost!

Shifting 200 rpm below 2000rpm will cause your safari to shudder and vibrate just like my dog shakes the water off after a bath. He sure is happy after with his vibrations, you wont be happy with vibes in your safari.:D

OT> with no offence meant to anyone but I have no respect for anyone who buys a Safari and then tries to extract high mileage from it by short shifting at 2000rpm and below. why spend so many lakhs in the first place. Save your money.

I know about the oil tolerance issues. but lets see. 3rd service to be done at 28000kms. The war horse is currently parked in the stable for the next 3 weeks.

Engine damage may happen later or much later. Could be 50000kms or 2 lakhs. I dont like to think so much. Its not worth the stress. Enjoy it while it lasts while I take reasonable care. Thats my motto. I cannot spend brain cells thinking too much about a horse. I ride the horse, the horse dont ride me.
Id like to treat this one like a war horse. Sometimes its wartime and sometime peacetime. 15-30k was wartime. Pampering will happen now,when Im more relaxed.:)
