Is it normal? It’s only when the lights are on for a short journey, condensation appears at the low section of the front cluster. I last used it in the dry just before the snow.

Running with them on all the time should cure it.....and making sure the rubber grommet/protector is sitting pretty, too.

This will need getting in to the headlamp and checking it is in position.

Nothing as such to worry about, but the condensation will cause rotting and this can become a MOT fail. Will take time, though.....and the problem should clear itself no matter what you do soon, when the temps get more warm and stable.

I wouldn't worry about it Mr Sea. My Jim Clark SC does exactly the same, and I am fairly certain it is caused by the twin oil coolers mounted underneath each headlight cluster. Something to do with the combination of hot air from the back of the oil coolers and cold air running over and around the headlights...

I've seen Exiges and 211's doing exactly the same thing, which both have oil coolers in the same place.

Cheers for that Niki, right then, a spanner to remove my oil coolers if you please Watson.

What build number do you have? I haven't seen another 25 SC yet (since May 2009) and I was the only Type 25 SC at Snetterton for the 'most Lotus on track' record attempt in June last year. There were two or three of the first Type 25's and very nice they were too.

no. 9 here, I've met the owner of no. 10, and I'm aware of 6 or 7 other owners over on SELOC.org.

smile Obviously only applies to S2s though, and I could of course be talking cobblers! I'd like to have a look at a car with a single oil cooler some day, and see if only one side steams up to prove the hypothesis...

If it's not that, then it could just be heat from the headlights against the cooler air running over them...

My SC does it, without oil coolers.

I have yet to do it but this is what my dealer told me...

"the condensation is because the units are closed

this is easily accesible by the rear side of the headlamps,

remove the plastic panel with 3 screws (2 x lower fixing + 1 x top fixing),

then you see 2 x grey caps - remove them - open at the rubber part the
vent."

You should leave it open for some time (30mins?). A nice crisp cold day would have very low humidity and should solve the problem.

Fair enough, so it's not the oil coolers wink I removed the covers on my old S2, the new one does seem to have holes at the front of the housing, I wondered if they were for ventilation?
