What is the Issue?
Some people have commented on the difficulty in
controlling the acceleration at low speeds, both in and out of low range. The TD5 has FTC
(fast throttle control) which allows longer pedal travel in low range and shorter pedal
travel in high range. This should give more control in low range and better access to
power in high range, thereby improving on road acceleration.

I have just read comments from Jonathan
Edwards concerning 'jerky' throttle control in 1st/2nd gear with TD5
engines. I have experienced similar problems and have put up with them for
2 years since buying the Defender from my brother who bought it new (and
experienced same problems). As speed bumps seem to be breeding faster than
rabbits round here, I was considering having it 're-chipped' by a LR
specialist in the Midlands, but was reluctant to go down that road when
quoted a cost of £500+VAT!!! I've tried Jonathans suggestion of letting
the clutch right out before accelerating and it's like magic!!! Problem
solved and saved me a packet! Don't know why it works, but it does and
suggest everyone tries it before going to a lot of expense. Bring back the
good old TDi!!

The Discovery TD5 saga.
I own a Disco TD5 2002 Model and boy am I an unhappy camper.
Problem 1:
From day one I experienced problems with this car, especially the
uncontrolled jerking between 2800-3000refs. Everything from airflowmeter
to
jetcalibration to ECU was replaced. After 1 year and the last 3 weeks in
the
workshop the problem was apparently found. Software issues!
Problem 2: Electric window system broken. Replaced and hopefully it will
last.
Problem 3: Electronic Door locks. Passenger Door broken and replaced.
Tailgate door broken and replaced.
Problem4: Tracktion control not functioning front left. Not fixed.
Problem 5: DUST DUST DUST. This car seems to be only half completed. I
have
never in my life seen so many missing dustproofing rubbers.
I think for the price I paid for this car, there should be a hell of a lot
more quality available. I also recognize the fact that this car may be one
of the few Disco's with excessive faults on it. But if you get stuck in
the
Ugab, you feel like wrapping this car around the next landrover dealers
neck.
I would love to take the landrover crew for some SERIOS off-road testing
in
the terrain, have the cars stranded and let them push them home. Where did
they get the quality awards from and what for?
Thanks for giving me the opportunity to air my frustration.

Dear
Landy-on-line
Thank
you, for the great site. I would like to submit some information regarding
the TD5.
I
own a 1998 Defender 110 TD5. When I purchased the vehicle I was very
disappointed as it had this terrible jerking problem when pulling away
from a stand still. Even when traveling at slow speeds in the game reserve
in 2nd gear it had the same problem.
I
contacted 3 or 4 different Land Rover agents and nobody could help. I
tried the Technical Consultant mentioned in your site and had no joy,
however I took my Defender into Land Rover Port Elizabeth and they
downloaded some new downloads onto my ECU.
The
jerking is a lot less if not gone and the vehicle seems a lot smoother.
I
would like to highlight something that I have learned while driving the
TD5 which is different from driving my Defender 110
TDi 300. ( This is my 3rd
Land Rover, both others were TDi 300’s )
When
pulling away from rest, let out the clutch pedal completely before you
accelerate. You will find that it will not stall and the jerking will
disappear completely. You can also cruise in 2nd gear without
touching the throttle and enjoy the game viewing as the motor just ticks
over. It takes some getting used to as this is a completely different way
of driving. I found that this solved my problem. Another plus that I have
discovered was to replace my standard air filter element with a K&N
replacement type. It fits into the standard air filter box and is very
cost effective as it is a “ washable “ type of element and can be
re-used for many future services.
Keep
up the good work.

After 90 000 funtastic
km in my Defender Tdi (96 model) I "upgraded" to the TD5
Defender 6 months and 10 000 km ago. Biggest differences are: lots
more power, lot less smoke, lot less noise, lot more diesel burnt (7,4
km/l where my TDi regularly did better than 8,5 km/l). The power is
great, although mine also needed adjustment to overcome the severe
turbolag at low revs.
The reduction in black
cloud on startup is impressive - no longer necessary to check in your
mirror that your hosts are clear of the exhaust before you start, or
that some poor guy isn't parked next to you with an open window right
next to the exhaust (as happened to some unfortunate smoker in
Pretoria parked next to me)
Disappointments:
1. After 50 years of
offroad vehicle design and amidst all the fancy electronics, and
slowly fading interior lights, still no visor mirror for the
passenger? Does LR research show that Defender drivers only marry
rough and tough females? I actually know quite a few Defender owners
with surprisingly ladylike wives, or are we the exceptions?
2. Still on the visor: It
still can't swing sideways! Such exquisite luxuries are reserved only
for Discovery and Range Rover drivers? Same research probably show
that Defender owners are always driving due West towards the sunset
like in the movies, never to the North or South?
3. The radio. Albeit to my
uninformed eye a very fancy model, it's too fancy for my liking. I
prefer a radio with numbered preset buttons. If I press 4 I want my
station, I don't want to scan all 6 to find my choice. Plus the search
and preset buttons look so much alike, that I end up searching from
scratch most times.
4. Gearbox clearance. Also
after 50 years experience from the "best by far", a gearbox
that knocks against the floorpanel when going through bad tar patches
that even my Jetta can negotiate with ease. Come on, Land Rover!
But still a great vehicle!
The mags grow on you after a while, and the luxury of being able to
talk on your cellphone (and to each other) while driving enhanced our
love affair with Land Rovers and each other.
And the Fuel Throttle
Control? When I asked Broadway Land Rover in Witbank to check if my
Defender was fitted with the correct chip, I was told it hasn't got
such a thing. :-)
I'll get it checked by Cusson's whenever I'm in that area again....

I agree with the difficulty in
controlling acceleration at low speed.
My recently purchased new TD5 Defender feels
as though it is sluggish at low speed.
I took it to Safari Center Braynston's off
road track recently. I trouble at very steep inclines to
control the speed, low range, difflock attacking it at about 2200RPM I
had to back off several times to get up.
All in all a great vehicle however.
Will somebody please tell those LR sales
persons out there that the consumption is NOT 10 km/L (my pet
hate!)

Should your TD5 Defender be jerky in low range and high range 1st
& 2nd, you should ask your dealer to check that your vehicle has the correct throttle
control unit fitted. I had mine changed by Auto Alpina (Boksburg) and my
vehicle is now much smoother. For your information the old control unit's
part No. was MSB110170 and the new one is MSB101171. The contact person at Land Rover is
