Hi everyone, I know this has probably been done to death, but is there any update on whether anyone is putting together a list of people who need window seals, part numbers C117U0009F & C117U0010F, in case we can get a bulk buy discount? Many thanks.

I hope the MLOC Team can advise! The header tank cooling levels, on my 2002 S2 Elise, has started fluctuating 20mm below the min level, when cold, to just below the max level when warm. Images below (I hope) I’ve had the car from new and the coolant level has stayed consistent between the min and max levels until now!! There is no obvious coolant loss under the car and the oil dip stick and oil filler cap are just showing clean oil. I have changed the pressure cap but this has not changed the situation. Im not sure what my options are and PJS/Unit 4 are over an hours drive away and I’m reluctant to travel that distance!! Any help and or advise is…

A few days ago the engine management light came on on my 2008 Elise. My OBD reader said fault P0638 which is to do with the throttle control I believe. Have sprayed the throttle position sensor contacts with contact cleaner and removed the air inlet pipe, the valve rotates by finger when I push it and then rotates back when I release. The light has gone of and engine idling ok, but i'm getting this buzzing sound when the ignition is on, which goes away when the engine is started. Maybe the buzzing sound has always been there and I've never noticed. Is it normal ? 20230806_170618.mp4

Hi folks . Just doing little ferrying jobs on the exige whilst I wait my new harnesses touching down so I can actually drive the thing . despite being relatively new and not rusted in place the rear retaining screws on my discs appear to have developed a cheese like consistency and I have had to remove with larger torx fitting . Does anyone know what size the bolts are and if an off the shelf euro car parts item will suffice as I can’t bring myself to pay the 8.34 postal charge for a £4 item from the usual lotus suppliers ? or if anyone has 2 spare they could pop in the post in exchange for a beer at LITP or similar meat that would be awesome cheers rich

On Sunday evening after a glorious and spirited drive back through the Welsh mountains the dash temp gauge began to fluctuate at 67/68 then jump back to 87/88 then drop to 79/80 and has continued to do this after an evening left on the drive to rest . A bit of googling suggests the blue thermostat / sensor may be shot and needs replacing . the car is a 99 S1 Elise and despite a reasonable search I can’t find a definitive guide to how to change this part . I am hopeful it can be quickly removed and a new one fitted without the need to drain down the whole system and hopefully will only need under trays and wheel arch liners out . Or am I dreaming ? as ever , any a…

I think it’ll be obvious as to where to re-attach the coil spring once I get myself folded into the Lotus-position, but where has the hair-spring come from?!

Hi I need of some info / help The car is 2004 Elise 111R and I'm looking at fitting quantum dampers which come supplied with new damper mounts. I'm tackling the Front drivers side first....the other wheels seems a little more straight forward. All bolts/nuts come undone easily bar one (highlighted by the orange circles in the pics) this particular bolt/nut is quite rusty, its been covered in WD40 but its no use as the whole thing just twists, so it's not really coming undone, managed to get a little bit undone. Clearance is also extremely tight so not able to fit many tools in the gap. 1) Any idea how to undo it? or is there a way to get at it from…

Hi all, My son and I are new owners of a 2005 Elise 111R and we need a little help with a couple of things! We did manage to find Lotus in the Peak today but didnt know where to start! 1. The alarm - it went off on the first night we had it last night. No idea why - so we just lock it now with the key, hoping it wont go off again, so far so good. Does anyone know of a mechanic near Sheffield who can either test it all or remove the alarm? 2. Also - when we go on holiday can i remove the battery to ensure the neighbours dont suffer any more false alarms? 3. Anyone know of any Sheffield (or close by - derbyshire / yorkshire) Lotus mechanics, not…

I thought I would post this in case it helps anyone else. So last year I fitted a quickshift stick on my s2 K series elise. Well, I say I fitted it but everyone that knows me knows that really means Gav, who has looked after my car for the last 11 years and 60,000 miles (where did that time go?!?) fitted it. That's Gav at Unit 4 Vehicle Services, Burton by the way. I liked the shorter throw but, perhaps inevitably because of the reduced leverage, it required quite a bit more force to move the lever, especially initially, when changing gear - which I didn't like. Mods are usually a bloody compromise aren't they? Anyway, I had read good things about the…

I got my S1 111s back on the road thanks to some excellent service from Gav at unit 4, but a stubborn coolant leak has been really grinding my gears, and my feeble attempts at fixing it have made it worse The rubber hose connecting the radiator return pipe to the metal pipe next to the gear box here: just won't seal at the end. It's been like this for ages, an occasional drip. Enough to want fixing but not enough to justify mangling the old rubber 90 degree piece by tightening the hose clip and adding another hose clip. After a couple of miserable hours under the car it's worse than it was before and I really think this rubber section needs replacing.…

My S1 elise has Koni yellow Lotus sports suspension coilvers fitted by a previous owner but failed its MOT last Friday due to one of them leaking. Phoned a company in Northampton who repair them, but they said they are very expensive to repair and wouldn't bother unless you wanted to maintain originally (the mechanic there told me he'd refurbished a pair for a Ferrari owner a few years back and the cost was £600) So have ordered a full set of new Bilsteins complete with brackets and bolts for £1200 from Elise parts. I phoned Bilstein direct for a price but they said we don't sell direct to the public Will let you know how I get on with replacing them and ne…

Hello All. I've got a 2001 S2 K series elise. It's started making an annoying low droning noise. Sounds like it may be fuel pump on It's way out. I've tried to find a new one but without luck so far. Any thoughts where can get one ? Thanks
