I know its a daft question but have you tried a new battery in the fob? I have had false alarm issues with that alarm if microwave sensor is set too sensitive but its usually a reliable alarm

Hi ted how old is your ls and has your fob got a black and a red buttom?

Hi wallace try and push on dash where it meets the screen if noise goes away then to cure it properly will req dash removal as there are some white dash mounting clips at the rear of dash that need packing out with some felt or sponge also when dash is out pack out demist vents and flange on bulkhead. We used to grease where clips located too certainly stopped it squeaking!! Hope this helps Sent from my GT-I8190N using Tapatalk

Hi all I too have had loads of probs with that alarm even when I worked at main dealers it was fitted to early ls400ucf20 and was a cat1 alarm but as in previous posts the company went bust and you cannot get parts anymore. It has a rolling code and the switch on the side of the fob is to turn on /off interior protection.they can lose cpde if battery goes flat and there are various ways to resync (not all successful!!) I have bypassed quite a few but no alarm but car starts.alarm was originally fitted at import centre after coming off the boat.later ls400 had different fob and used toyota tvss system with extras fitted here to make it cat1 Sent from my GT-I8190N using Tapatalk

Sounds like back plate catching inner edge of rear disc.the back plate has a lip that corrodes and swells and catches the disc.only catches when loaded on a corner Sent from my GT-I8190N using Tapatalk

Hi I have stripped and cleaned out rx hight sensors but usually the brass spring contacts corrode really badly and turn black so unfortunately its a new sensor or a known good one Sent from my GT-I8190N using Tapatalk

Hi only just read this post but it cot be a problem with the hight sensors if car has been on a two post ramp and suspension has dropped to full extent.usually its the rears. If you can disconnect the rods and see if they are stiff. I've not heard of any air suspension ecu reset when I worked at main dealers hope this helps Sent from my GT-I8190N using Tapatalk

You would have thought they would have checked them at least but you might have to check them again Bit of a pain though! Sent from my GT-I8190N using Tapatalk

Did the cam buckets go back in the same position? If I remember right you have to change buckets to adjust valve clearances Sent from my GT-I8190N using Tapatalk

It just sounded like that fault on vid used to get a few of them when I worked at main dealers.did you time both cams up ok? I think there were dots on cam gears to line up Sent from my GT-I8190N using Tapatalk

Just another thing I've not had new valves be noisy and go quiet after a while either Sent from my GT-I8190N using Tapatalk

Its not the valve clearances that are making the noise its the exhaust to intake cam gears that are rattling due to the scissor gear not having any tension.it cause an immediate problem but it req sorting asap. Shame you aren't near sheffield as we could do it for you! But it will req cams out and scissor gear resetting.its hard to explain but you need to remove cams and twist the cam with the scissor gear on and lock it with a 10mm bolt when the holes line up then refit cams and set up valve timing and rebuild Sent from my GT-I8190N using Tapatalk

Hi all just been reading this thread and it sounds to me like when the cams have been removed to remove the head that the scissor gear has not been locked before removal.when rebuilt the gears rattle against each other.req cam removal and reseting Sent from my GT-I8190N using Tapatalk

Hi sounds like vvti controlers getting noisy on start up usually inlet side on both banks .have changed these in situ without taking off timing chain cover using lexus special tools Sent from my GT-I8190N using Tapatalk

Hi when I worked at main dealers think there was a warranty extension on rear calipers but not a recall.i have freed off plenty of these on is and gs (similar caliper) though hope this helps Sent from my GT-I8190N using Tapatalk
