T350 Throttle Cable
Discussion
Hi all, planning a trip to the south of France for mid September and am doing some due diligence and getting a collection of spares together and working out what pre-checks I should do. I know the throttle cable is often an issue so I am taking a spare but could I ask does it usually snap at the pedal end? I guess the rotation (if not perfectly adjusted) as you press the pedal is what cases the damage over time? I will probably add a regular check of the cable to my normal routine just so I am on top of any issue before it is close to a breakdown scenario!
Also related to the throttle, I wondered if anyone who has an ECU reader can tell me what % each throttle should read at full pedal depression to the stop? I am guessing not all the way to 100% but would like to know the norm?

Great thanks Twinreal, that is exactly what mine reads! Not planning on making any adjustments just want to check regularly to ensure I can catch any issue before failure. So I assume I am correct in that it is 99% of the time the pedal end that snaps (i.e. this is where I should check for any fraying)?
It is very important to adjust the pedal end stopper (sorry don't know the english word for that). Best is to read the max value (the 94%) in the diagnostic software and then to adjust the stopper to this point mechanically.
I think one of the most reasons for snapping the throttle cable is putting the foot down with an incorrect adjusted stopper.

Hi Charlie,
As you know from the FB group, just got back myself.
I was on a trip round the Scottish Highlands in May and about 20 miles from the overnight stop my cable snapped (engine end) and I coasted to a lay by. Most annoyingly, I tried to source one last minute just before I left "just in case".
Not all bad though.. car was transported back down to London care of the RAC saving me circa 400 miles and a few gallons of fuel!
I now have a spare tucked away - better to have and not need etc etc!
I would also carry - a basic tool kit with spanners, some insulation tape, a selection of blade fuses, a 100amp main fuse, a spare relay, 2.5 litres of oil and tyre weld. Plus a few other obvious bits and bobs

Hi Arthur,
Glad you had a good trip this time round without any issues! Would be great to see some more pictures
With your cable break, was it the cable or the R-clip thingy that broke? I think I will now check both ends regularly, especially before any major trips! Hard to understand why it would break at that end as it is not at any awkward angle or anything....
How did you find the heat in the cabin over there? As we are not going over until mid sept it shouldn't be a major problem as temps usually between 23-25c which isn't too bad. Especially when on the move.
This is my current list of spares
Tools:
Small ratchet set including screwdriver, bolt and allen bits
Some bigger spanners of common sizes
Small Pliers
Anderson Jump leads
Insulation and duct tape
Selection of cable ties
Heat Insulated Glove
Tyre pressure reader
Magnetic Pen
EvoOlli Mobile ECU Reader
Torch
Spares:
Numerous selection of spade fuses
2 general yellow relays
Fuel pump relay
Various strip/midi fuses (80,100,125amps) and holder (for under airbox) and 80amp fuse passenger footwell
Fuse/relay layout diagram
Coolant cap
Throttle cable
Set of Bulbs
Tyreweld x2
Fire extinguisher
1l Oil
1l Coolant
Have I missed anything!

Didn't know where Patagonia was, so looked it up and I would love to drive there! Some of the pictures look amazing....
Was thinking I could easily take my socket head and breaker bar but would then need a bottle jack to do anything. Seen this that would be well handy:
But pricey though!I have a normal size bottle jack that I could take and would just need to park on a kerb if an emergency arose!

Hi, my cabel went couple weeks ago, it's the outer rubber or plastic cover which was the issue it has broken up and no longer could be used as the keeper so cable just pulled through resulting in no throttle.. A very small jubilee clip and two very small screws clamped around it and now OK.. 😜
Have to order a new cabel any ideas where from guys Cheers..

As the thread has been resurrected, people may wish to check they have a physical throttle stop as TVR didn't like to fit them (this goes back historically to most of the cars they made). Later T cars may have them from factory, some have been retro fitted but plenty out there with out them.
I would have some of that stop leak tape in the kit (wrap it tightly around leaking silicone tubes & lock with other tape on top)...
AA man showed me that stuff as he fixed a leak on one of the original small coolant tubes near the top of the engine (it psssst on me after parking up).
Can get you out of trouble for small leaks and to your destination. Regular tape won't take the pressure.
