Hello from Newcastle upon Tyne LC5 2006 1KD with ahc issues

[simples]

hiya thanks firstly to all contributors and sharers of knowledge , ive just acquired a land cruiser 2006 LC5 126k miles 1 owner from new so virtually untouched example im here to look into issues with the rear height control system as it seems to be playin up , it like to sit on the bump stops when the dashboard indicates this is normal ! , i can lower and raise with techstream so confident the compressor and air bags. Are working It did have code c1714 since I’ve cleared code its not came back but the suspension is still not working correctly, so I’m here researching before changing the rear height sensors for some off eBay to see if this cures the problem ,,,so far I’ve changed engine oil ,and filter ,replaced the timing belt and tensioner , fuel filter and cabin and air intake filter both inner cv boots and anti roll bar bushings

, ive got a techstream running on laptop which so if anyone nearby needs their land cruiser plugged in drop me a message if I can help I will
