Hi all,

I had the opportunity to buy another L322 from a friend so I went for it with the plan to resolve a few issues and flip it for a bit of a profit. Well, the best laid plans and all that :(. Ha, it broke!

It's a 2008 ('58) TDV8 Vogue SE 3.6. I drove it around for about 3 weeks to shake it down and it drove absolutely fine aside from having very heavy steering (there's a clue here I'm sure). I did a wheel bearing, replaced the front brakes, full service (all filters) replaced the coolant and brake fluid, couple of parking sensors and gave it a thorough clean.

The plan was to take it to a friend in Cornwall as there is such a shortage of them there(and they command a premium) and he would sell it after running it around for a couple of weeks. Ideally, the additional profit would cover a bit of a jolly for me to drive it there, have an evening in the pub, we drive back to Kent, he visits his parent and then takes it back. I appreciate this is not a particularly shrewd business model but it's a bit of fun.

All went really well until I got half way there and found I had a bit of boost trouble which was (to nobody's surprise) a split inlet manifold just like my RR. Simple diagnosis and a drop of Q-Bond resolved that and all was good. Drove back to Kent 300 uneventful miles and then while here, the steering fixed itself. Now it is light at low speed and weights up as the speed increases - Great, even if a bit odd we think.

Cut to day 3 and he's just over 150 miles from me almost back as far as Devon, and suddenly, GEARBOX FAULT!. It's in limp mode and won't shift past 3rd gear. If you stop and restart the car the issue goes away. Once it had cooled right down at Exeter for a couple of hours, the issue didn't reappear. Just prior to this happening the car was vibrating going uphill under load as if labouring and perhaps in the wrong gear.

The fault hasn't reappeared as going into limp mode but it still vibrates a little when climbing steep hills at speed as if not downshifting when it really needs to. My feeling is that it's electronic and related to heat-soak into a sensor as it only happened after several hours of driving. Below are the fault codes:

Speed sensor is a bit of a misnomer I feel as the speedo is working fine as are all other functions but that is driven from the rear wheel speed sensors as I understand whereas I feel this one is from the gearbox and perhaps controls the Servotronic steering also? Set me straight on this if you know how it works please.

So, does anyone have any experience of this? I've asked him to take the car to a local LR specialist for advice but I thought I'd ask here too.

We really can't sell it in good conscience like this now and I'm sure that anyone wanting to buy it like this would give me a hefty kick in the trousers on it's value (I don't blame them either!). I need to get this resolved so that I can reduce my current LR stock!

Cheers all
 
It's booked in for Monday13th now and I'll update when I know more but still interested in your thoughts and opinions.

He tells me it is a 'typical Cornish business' as they called him back to discuss his cam belt enquiry. Ordinarily alarm bells would be ringing with me but I'm assured that is the just the norm in Cornwall and this specialist was recommended to him by other LR owners down there.
 
Your P0500 error relates, as the code reader states, to a vehicle (i.e. wheel) speed sensor and not to either of the transmission speed sensors.

The vibration when climbing gradients could possibly be caused by a worn torque converter lock-up clutch.

The clutch slip codes for 5th & 6th gears may be an indication that the rear stator bush in the transmission is worn, allowing the E-clutch to slip. The E-clutch is used in 4th, 5th & 6th gears. In 5th gear the clutch sees 125.5% of input torque, in 6th gear it’s 100% and in 4th gear it’s 72.6% so it’s most likely to slip in 5th gear first, and then in 6th & finally 4th. If the controller senses this slip it will restrict the transmission to gears 1-3 to prevent the E-clutch engaging.
