Excellent, thanks again tim

Thanks tim, Much appreciated. Will it also be ok for the LSD? Ben

I want to change the gearbox oil on my car as I have no idea when it was last done. I already have a gallon of ep 75/90 gl4/5 semi synthetic that ive had for ages that reckon will be suitable however is says that it is hypoid gear oil on the label. I think its one of those oils that's suitable for various applications but i just wanted the opinion of others before i change it. Would this also be suitable for the lsd? Pic of the label below, What do people think? Thanks, ben

No problem Alan, i shall let you know what i find. Sounds like you're going to understand the working of an alarm system much better than me! I am fine with the oily bits and basic electronics but after that its a bit beyond my knowledge.

That used to be quite a common problem, normally due to a replacement windscreen not being sealed correctly. I guess the replacement companies figured out how to do it properly now so you don't hear as much about the issue. Symptoms are headlights staying on, hazard lights playing up, alarm issues and other problems too.Here is an example of what happens: http://www.lexusownersclub.co.uk/forum/topic/94492-efi-relay-clicking-removed-junction-box-need-help/ this one wasn't too bad and was cleaned up. Others have had to replace the fuse box which I think costs around £180 for the part. Thanks for this link, i will check mine out. Although my car appears to still have its original screen fitted and I've not had any issues other than the alarm problem?

Siren is on the drivers side / right behind the boot side panel. It is easy to get to. I only sourced another complete siren so i could remove the original and fit replacement in one go. For £11 I thought it was worth a go. I shall take my old unit apart and have a look to see whats inside and let you know. On the era of these cars I'd expect it to be a ni-cd or nimh?? I've always assumed its rechargeable but i really dont know? I didn't try the car with the siren removed as i had the main battery disconnected. I'd read in other posts of people having problems with the alarm going a bit crazy when reconnecting everything so i made sure it wasn't armed and removed the neg lead from the battery first. If you could simply bridge a couple of wires to bypass the alarm and retain the remote locking that would suit me down to the ground! I did contact a local auto alarm guy a while back and he suggested that as the siren and horns sound it wasn't something he thought he could easily fix and wasn't interested in looking at it. Thing is, the problem must be traceable and fixable! You mentioned dampness in the fuse box? I've not heard of this issue before, i will check mine Ben

I fitted a replacement siren to my car over the weekend, not sure if its cured the problem or not? It seemed ok on Saturday, however i didn't trust it to leave it overnight. I rearmed it on sunday morning an it went off within 20 mins! I'm wondering if it could just be the back up battery in the siren needs to charge? With a week of using the car I'm hoping this might happen? I'll try again over the coming weekend. I have also searched alot about this problem but cannot get to the bottom of my issue. Its a pain not being able to lock the car with the button, I'd settle for the alarm being deactivated and the remote locking working if i could work out how it could be done if possible? One thing I've not tried is removing the roof lining and looking for a damaged alarm wire, purely as i see this as unlikely?

Well i found an exact replacement siren for my car, hopefully it will arrive tomorrow and I'll get it changed over the weekend I'll let you know if it sorts my problem. It would be really handy not having to manually lock the car all the time!

All my door switches seem to operate the interior light ok so i have disregarded them at the moment. Im wondering if a dodgy switch could just be causing the light to come on, cause the volt drop and cause the alarm to sound? Suppose an easy way of testing that theory is to just remove the interior bulbs? If the battery is built into the boot siren i might just give another a go? They go for about £15 on ebay. (My car is the saloon) The estate must have the same siren somewhere?

Dave i have the exact same problem with my 200. I have disconnected the interior sensor, bonnet catch sensor (so it thinks its always shut) changed fob battery but still the problem persists? Did you manage to find out if there is a back up battery to replace? Tbh I'll be happy with having the completely disconnected and just the remote locking working if thats possible?

Yes i am interested, would you sell the front pair on their own or only as the full set?

Interesting! I wonder which type it is? Thanks

do you still have your original sport front coil springs? if so and you don't want them I'd be interested in buying them off you I found out this week at mot time that one of mine has a snapped coil so am after a standard replacement, finding replacement springs for a sport model seems to be difficult! thanks

does anybody know the difference between the standard suspension setups? I have a late 2001 sport model which I believe is a facelift model. I took it for an MOT and I have a leaking rear shock absorber and a snapped front coil spring so need some replacements. most online suppliers seen to only list one type of spring for all models which cannot be correct if the sport models came with slightly lower suspension as standard? its seems the same issue with shock absorbers too. buypartsby list the parts at a good price but I just want to be sure its the right bits for my car. I don't want to buy a pair of front springs and end up with the front of the car higher than it is now, I assume it is only the springs that were different between the sport models and se models and the shocks are the same? does anybody know as searching the web seems to find conflicting information. Any help would be much appreciated! thanks

You know at first I really thought we had it sorted, but never mind! Thanks for your suggestions, it did help alot. I'd still like to get to the bottom of it but I am not going to spend loads of money doing it. I am comfortable working on cars but with this I have run out of ideas with. It is clearly getting a volt drop from somewhere but I don't know where?
