#941 of 5002 Faulty throttle body on 2001 DII
Aug 02, 2001 (7:46 am)
This is a quick follow up to my previous post on the 2001 DII loaner vehicle that wouldn't stop accelerating - around post 873 on the board.
The dealer has since inspected the engine, and found the problem to be a faulty throttle body - a mechanical component linked to the throttle cables that essentially controls the throttle/intake. The aluminium unit had apparently twisted under heat and pressure which is due to two reasons (as far as the mechanic's concerned):
1. The car wasn't professionally broken in (you probably all know that Land Rovers have to go through a fairly strict breaking in routine that's about 30-35 miles long). This, in my humble opinion is not a reasonable excuse/reason in and of itself.
2. The throttle body component was not manufactured to the ususal high quality standards at the Factory, causing the circular device inside to get stuck at full throttle - I was surprised that such a "heavy" piece of aluminium could twist, but there you go. Apparently Solihull has requested that the piece is sent back for further examination. As per the mechanic, no official recall exists on this yet, but reports are starting to trickle in that certain 2001 DII's, within a specified VIN range, may be impacted. I suppose an official recall is dependent on the number of complaints.
The good news is that I've since driven a second loaner car that drove perfectly. I'm picking up the original loaner can (fixed and properly broken-in) for a final test drive before I make a final purchasing decision. The repair itself is fairly minor, only taking an hour or so. I still like the car.
Moral of the story: make sure your car's properly borken in when you pick it up, and also get the dealer to thoroughly inspect the throttle body for an abnormal contortions/uneveness prior to pick-up.
Tincup, if you listening, I'd advise LRNA to work with Solihull to fix this problem quickly (should be cheap to do so), before someone has a serious accident. Perhaps a recall is warranted.

Your retailer would have been in contact with our onsite powertrain engineer, he would have requested the part. All driveability or braking complaints are required to be filed with LRNA, so our engineers can spot trends, and take the proper corrective service actions. These could be in the form of TIB's or recalls. Safety of our customers is something LRNA does not take lightly.

Thanks for the update regarding the stuck throttle condition.
A thought: if that was a new-ish truck and it experienced several trips to redline, to the point of the rev limiter kicking in, that cannot be a good thing. If I was you, I'd have a long long talk with the service manager about possible outcomes before I wrote any checks.
Yes, these are durable trucks but... they are also not magic. Very likely there will be no problem at all, but you'll feel better having some sort of limited coverage statement in writing... along the lines of "damage or premature wear to internally oiled components due to over-rev condition when new".

Thanks for the advice, but rest assured that I wouldn't event consider buying the loaner/demo vehicle after that incident.
Truth be told, I'm a little hesitant about driving the vehicle even after it's been repaired, but it's the only demo car the dealer's got with ACE. Having driven both a car with and without ACE (OK, so I only drove the ACE car briefly), I think I prefer the sturdiness of the ACE, even if it is noisy.
Do you, or anyone else on this board, know if ACE is generally speaking reliable? I've seen recall or service bulletins on ACE before, so I'm just wondering if I'm setting myself up for a lot of repair time with an ACE car?

I've read a few scattered stories of ACE problems, but really not very many. I suspect it's as reliable as any other major component on the truck.
Personal opinion: I avoid as many complex vehicle systems as I can, thinking it will prevent having to deal with those complex systems somewhere down the road. Just my $.02

We haven't experienced many problems on ACE. The recall was due to problems with a hose redesign to cut down on noise, but the resulting harmonics caused hose fitting failure, resulting in leakage. The lack of fluid would not mean you lost the sway bar effect as failure mode is full stiffness on the bars. Drive an ACE car if you are considering it as the main complaint with this system is noise. It is not as quiet in the cabin as a non-ACE car. If the noise and price doesn't bother you, it is a worthwhile option.

I have a shot at a 97 with everything including brushbars etc. About 31,000 km (20,000 mi) and am trying to squeeze for Cdn$26,000 (US$17,500). Clean and lady driven in city only. Was a bit unsure reading reviews but this group certainly brings passion to the side of owning a LR. I hear thirsty and unreliable. Should I be concerned. Unbiased comments only!
#948 of 5002 Question for Tincup
Aug 03, 2001 (11:11 am)
I have heard that Land Rover offers a 15% discount on accessories for the X-Plan... Is this just a one time offer when you purchase your vehicle or can you use the 15% discount at any time after you have purchased the vehicle to buy accessories?
Aug 03, 2001 (11:42 am)
X-plan only covers new vehicle purchasing, so any discount would only apply to items bought at that time. One thing to consider about accessories, is any accessory bought with the vehicle (listed on the buyers order) is covered for the full length of the vehicle warranty. Accessories bought later have a 12 month warranty.

Thanks for the info...
