yup

will have the whole thing checked up - all brakes + the LSPV
better safe than sorry
cheers

Folks Skidding on dry tarmac at 70 -100 kmph should never be considered normal even for vehicles without ABS. I peiodically test my breaks ( specially after service) on empty road and I am able to stop in straight line from 120 kmph on surfaced empty road , I think brand of 2 tonn Iron block does not matter much.

I have been running in to this problem with my new mHawk from weeks. The real left wheel locks up even at slower speeds if I hard break. I have the SLE version, so it does have ABS, but I don’t know if ABS is available on all four wheels or only the front wheels. It happens on dry tarmac occasionally but happens mostly on loose gravel. The point is that only the said wheel gets locked up.

A.S.S could not find out the reason though they tried twice. Two weeks back I found that the tyre had a minor puncture (read tubeless) so the air pressure was less by a few PSIs compared to others. I fixed the puncture and for few days I didn’t encounter this and was happy. Now from last week, it appeared again. Type air pressure is fine and has no puncture.

One other thing is that I have never seen my ABS functioning (i.e no usual ABS beating sound etc) and a bit worried it isn’t working at all.

@ casperrider: the ABS in the scorpio works for all the wheels. BUT the scorpio has a 3 channel ABS compared to the 4 channel ABS in some other cars. this means there are 2 individual sensors for each of the front wheels but only 1 common sensor for both the rear wheels. in other cars, 4 channel ABS has 4 sensors for each wheel.

has your issue got something to do with this?

[CasperRider]

@raj_5004: Thanks for the info, I didn't know that Scorp only has a 3 channel ABS. Even in that case, I wonder why only one wheel gets locked up, instead of both and it happens only on the real left wheel. Looks like I will need to take it to the A.S.S again and do a detailed investigation. I'll update on the findings. Thanks again.

@casperRider:

It is definitely a flaw with the vehicle and a dangerous one. Put your foot down and have them change the brake assembly for the wheel with the issue. It is possible that there maybe block in the brake lines to the wheel that is not locking causing more pressure to the wheel that is locking. Either way if they cannot pin point the problem and the symtpom can be easily replicated make them change the brake assembly. Escalate to Mahindra customer care. Lock wheels are not something you should drive with.

I also feel it is very petty to offer only a three channel ABS on the Scorpio when Safari can offer 4-Channel ABS. I doubt the difference in cost is that much. Guess Mahindra wants to claim the *ABS* feature while giving something half cooked. Petty, I must say....

Sorry, I usually do not comment on somebody's decision. But you should have taken HVK's suggestion about service at MICO.

That should have been a more pressing reason for not entrusting pump work to the service centre. Mounts of course at TASS only.

After my recent sojourns in my Marina to Pamba and Bharananganam, I have reailsed that my visit to MICO is due (Both for coins which out banks refuse to part with)!

[CasperRider]

@4x4addict:Thank you for your guidanace. Yes I know it's long overdue, but just because of my schedules I couldn't spend a day at A.S.S yet. I will find a way quickly.

hey trrk, the A.S.S will be giving the fuel pump to MICO itself.

The bobbing & wavering quality of ride, in my opinion, is due to lower damping ability of the shocks. This is evident at standstill itself, when you bounce the vehicle from the sides and release it. The vehicle continues to bob up & down for another 5 to 6 oscillations, before fully coming to rest. I have checked this on three other leaf spring scorpios at an ASC and confirmed this. A well damped suspension must settle down to rest within 2 oscillations. (When I do this on my Ikon, it settles down at first cycle itself! Of course, this is a low slung sedan with a very low CG, so wrong yardstick for comparison).

Apart from GD's idea, & the composite leaf spring (supposed to have better inherent damping characteristics), shock absorbers with better damping seem to be only solution left. But the aftermarket shocks start at 38k for the full set (Bilstein B6), unless someone can suggest shocks of another brand, which is better priced.
Cheers, Mohit

Hi all, I upgraded my Scorpio's shocks to Bilstein B6 today. Details at :

I know. But it would have been better if done directly as they allow you to watch the service!

okay, i will find out if thats possible.

need some inputs from people owning refreshed scorp 2009 model +

1. I dont see any spare tyre pressure on TPMS display - is that how it is supposed to be?

2. after a recent puncture, I change the the tyre - the spare tyre when deployed continued to shown 29 psi/26 degrees temp after 50 km run - is that normal as well? Original tyre when corrected and replaced back gave all the right temp/pressure indications.

3. The TPMS sensor starts beeping once tyre pressure goes below 26 (I think) - so how do you drive a 4x4 in sand - it is normal to deflate tyres below this limit on soft sand. any way to turn off the beeping?

Cheers

1> In previous version all the 5 tyres pressure and temp were shown, with refresh only 4 tyre pressure and temp are show, but 5 are monitored, if the tyre pressure goes below the threshold it should beep for spare too.
2> When you change the tyre, you need to let know the system, else it will not monitor the right tyre, too make the system monitor the changed tyre, you need to look at the manual, there process is mentioned, you need to press the TPMS system button to let you are exchanging the tyre with the spare tyre and once done, you need to release at least 2 psi pressure to make the system recognize the new tyre correctly. once this process is done the correct pressure and temp is monitored! you need to do this same process again again when you change the tyre back.
3> I don't know if this is possible.

In my 2004 Scorpio (88k on the odo), while releasing the clutch in first gear to start off from rest, I feel the whole vehicle shudder. I then raise the engine rpm a bit, release the clutch at a slower rate, and take off. This is more pronounced when the vehicle is on a slope, with full load. Once I start moving, the pick up is normal.

Do I need to check my clutch plates? Suggestions please!

Clutch plates, pressure plates the works. Get it opened up and observe next to a brand new piece. Should logically change everything in the clutch assy.
