Adjusting Alarm Sensor

[RobM77]

I've had problems since day one with my Elise's alarm going off in bad weather. It's the sensor at the back of the car that's at fault (rear window or bodywork near to it). At the last service the indie I go to claimed to have turned the sensor down, but I think they turned it the wrong way as I have to garage the car now to stop the alarm going off! They're too far away to pop in and get it rectified, as is my nearest main dealer, so I was going to have a go myself sometime.

Does anyone know where this sensitivity adjuster is and which way I need to turn it?

It's a 2004 MY Elise S2 111S

thanks.

Identical car mate and i'm pretty sure the handbook tells you how to adjust it. The sensor is behind the plastic panel covering the rear bulkhead and operates by radio waves through the plastic.

Mine's probably not sensitive enough, the neighbour's cat often sits its fat arse in the middle of the soft top and it dips down into the cabin a little - the not-so-little bugger!

(Shame i'm a cat lover really)

Excellent, thanks. I live away from the car and handbook, and when I get home to work on it I won't have time to find out how to adjust it, so I thought I'd ask. From memory, that rear panel is just held on by some screws. I'm guessing they're all accessible without removing the seats?

Same model as mine - I think from memory you may have to remove the seats to gain enough access. When fitting the harness bar on mine I obviously had the seats out and saw the sensor then...sorry if this wasn't what you wanted to hear!!

Thanks. It's ok, I'd been meaning to get them out to clean the car properly anyway
