One funny thing, I was trying to register my Scorpio's VIN no with Mahindra's site. It tells that they will send the service reminders. Somehow the site doesnot accept my VIN . I debugged the java script it came out that the year they expect as a numeric but 2010 is character A so it has to be alpha. Somehow the person who created the site doesnot know how the VIN is formed. anyidea how i can get the VIN registered?

Regards,
Scorpio Fan

The rhythm of this sound is the same as normal idling, only the sound is different.

This occurs for the first 5 odd minutes of driving; once the engine reaches optimum operating temperature [temp gauge needle slightly to the left of the halfway mark], this noise goes away and does not reappear.

Is this something I need to be worried about, or does it happen only because the engine has become really cold due to the low temperature at night?

I have the same sound from the engine while cold. Its been there since the first time I saw the car prior to delivery. Was told that this sound was kind of normal for the BS4 Car, and was also shown 2 other pre-delivery vehicles.

It sounds like a tractor!!

I observe that the colder the morning, (Kolkata has seen record low temperatures this year) the intensity of the sound is more.

Not sure if this is a problem, but then it doesn't seem like one to me. Car runs super smooth once warmed up.

Two things I can think of, that can make that kind of noise:
(a) Tappet noise
(b) Injector noise.

Both are normal noises from a cold engine. The oil change probably washed out the deposits from the cylinders and tappets, and when the tappets run dry for a few seconds after cold start (all engines run a little dry at first start, which is why you

...make sure that I run the vehicle at idle for 2 minutes or so.

IIRC the mHawk engine has oil-damped self-adjusting tappets (Spike, could you confirm please?), so after the engine warms up and the oil flows properly, the noise disappears. In the old Amby engine, if the tappet adjustment was loose, the noise persisted even in a hot engine.

The noise from injectors is usually easily cured with a proprietary injector cleaner (Iftex System-D @ 1ml/litre for 1-2 tankfuls would be a good idea).

Hope this puts your worries to rest.

My vehicle is mfged in Feb '10; so I guess this characteristic is inherent in all mHawks

Same observation here. Last weekend, I started on a trip at 6 AM, and the intensity of the sound was definitely more than it is at around 9.30 - 10 AM everyday. Also, this sound is not heard while returning from office to home, though the vehicle is parked for 8-10 hours beforehand and technically undergoes a cold start even then.

Yup, ditto again. The sound persists only till the temp indicator needle reaches it's usual place just to the left of the halfway mark, which never takes more than 5 mins.

EDIT:

@SS-Traveller - Saw your post after submitting my reply to 1100D.

Sorry for bombarding this thread with so many posts; but I tend to be too paranoid about issues with my steed! But now, your explanation, along with 1100D's post above has definitely eased my concerns! Thanks!

An issue which bugged me a very long time ago has creeped up again in my scorpio.

I get the annoying trrrk trk tuk tuk tut sound from the front wheels when i do a complete steering turn and move the vehicle slowly.

It sounds like something breaking.

What might be the issue? what do i need to replace?

[mooza]

^^ Could be worn out suspension link bushes, or worn out wheel bearings, I guess.

Confirm if the wheel nuts are rightly torqued in the first place, just in case

Yes Sir! You are right, we call them Automatic HLA (Hydraulic Lash Adjusters)

More of Tappet noise rather then injectors.

Sorry for the late update folks.

@SS-Traveller - The engineer at the ASC told me the same thing you did. Also, now that the weather's turning warmer, I don't get this noise even if the cold start happens very early in the day [6 - 6.30 AM].

As an aside, the 20k kms service for my Scorp is coming up in a week. Apart from the items given in the user manual service schedule, is there anything extra that Gurus here recommended?

@Vikram, which model Scorpio is yours?

Had a bit of a heart stopping experience with my Scorpio on Friday. I was driving early in the morning and with the roads all empty appx. 80 KMPH speed, nearing a crossing I slowed down to about 60 before realising the Mahanagar Gas had dug up and filled half the road bang in themiddle of the crossing and about a couple of feet of yellow pipe was sticking out from the road probably to connect with the rest of it once the other part of the road was dug up and pipe laid. I gave a slight flick (left and straight) on the steering to avoid the pipe (still about 60 KMH).

The scorpio behaved very wierdly instead of coming on stright it did a snake routine and wobbled very dangerously, thankfully the road was empty and with the help of clutch brake gear combinaton I was able to bring it under control.

Issues: The steering is suddenly feeling verly light and a small pot hole is enough to jar the steering out of control, consequently I am conciously gripping the steering hard and with both hands now to avoid any issue.

Any ideas or pointers on what could be wrong.

@Spike - It's a Feb 2010 mHawk SLE.

Vikram, nothing special you need to do, just stick to manufacturers recommendation. If there is any specific query just let us know.

PS- Keep an eye on condition of tyres and suspension bushes.

From the last one month, I am finding that my 63k km, 2006 Scorpio SLX is taking a longer starter, in the morning as well as during the day. Its almost twice as long as it was in November. Any idea what could cause it? I find nothing else out of the ordinary and earlier thought it might be due to lower winter temperatures(8-12 degrees) but its still the same though the temperatures have normalized (20-25 degrees).

Thanks

How old is your battery? Is it getting charged properly? Check battery and alternator condition first.
