Many thanks guys. Food for thought. I'll check out the LAMBDA first and find a 7 friendly test station. Interestingly it was tested by a certain Caterham dealer in Mid Cheshire.

Jonathan,

I will have them in the archives somewhere but I seem to remember it was 1.7% 12 months ago but will need checking when I'm at home. Was thinking of sounding CC out to hear their views.

How long do we expect a catalytic converter to last?

Just had mine in for MOT and the tester informs me that it will not pass next years MOT as it is on the limits now (2% ). Can we adjust mixture settings on the standard set up?

Car is an August 2013 1.6 sigma with 4.5K on it. Lack of use could be one reason but it does get used (very hot) when I'm out.

Would have expected it to last a bit longer than this. CC replacement nearly £600

I change mine every year with Fords own Formula F synthetic oil and their own filter. I only do a couple of thousand every year though. Would not think necessary to change at a thousand miles.

Checked my Sigma - Brake lights only work with ignition on.

Went to check this morning and everything is fine - working properly. The indicator gremlins have gone to bother someone else.

Have sent a message

Thanks Jonathan, I have a meter but not a wiring dia. for the car (sigma roadsport)

Indicators / Hazards  do not flash. All bulbs illuminate when switched on with the direction switch and the hazard switch . Is it one of the relays? Done a quick check and all earths appear good. Suddenly happened, one minute fine and working as normal, next time I used them they refused to flash.

Any clues or should I just purcase a new relay?

Will,

It will most likely be the sensor (Approx. £70)or the air gap requires adjusting. Had the same fault last summer. Presuming yours is not very old so it will have the earth mod already done.

I had exactly the same problem this summer on my 3 year old roadsport. Speedo / odometer stopped working. Rear wheel sensor was eventually found to be at fault. Carried out the earth mod, (probably already done on your car) fitted new sensor and been OK since. The sensor is on the CC website it's just a b*gger to find it. Best part of seventy quid though. As all have said before, the sensor gap is critical and make sure it lights up on each castellation for a full 360 degree turn.

It's a new sensor. Speedo now works fine. Best part of £70 though*smash*

I bought a 1400cc 'classic' in 2013 which turned out to have questionable build quality when it was delivered and I'd had a good nosey about. When interrogated CC admitted it was a schools car but checked by them. It was so bad I rejected the car, with no questions asked they took it back and refunded  the cost. It basically need a re-skin.

It seems that at the end of the model run they gave the remaining kits to the schools to finish and then sold them as full CC assembled prices. Not pleased.

Thanks John, have checked resistance of lead at 0.4 ohm but not from the connector. Continuity from earth point is good to anywhere on the car. Will persevere!!!!!!!!!!! 

Carried out the earth mod and set the sensor - everything was working as normal for about 9 miles and then the intermittent fault returned. Sometimes the speedo worked sometimes it would not, so over a 30 miles route it recorded 18 miles.

Very frustrating.

I suppose a new sensor might be required?

All Screens come as heated. They are fragile though and do not use them to get into and out of the car, like my missus did. Replacement required, which takes an age.

I have (eventually) adjusted the speed sensor gap so the led flashes for the full 360 degree rotation (5 attempts!)

Carrying out earth mod WN572, but does anyone know how to remove the existing earth pin from the terminal block on the loom side? Do not want to destroy the block or splice into the wire.

Thank John,

I have sent you a message.

Appreciated.

Having now checked the sensor is OK, I think the earth mod will be the next item on the agenda. Does anyone have a copy of  factory mod WN572 or similar.

Is it coincidence that I fitted a 3rd break light (48 LED) approx 150 miles ago?

Spot on chaps. Will have a fiddle over the weekend. Many Thanks.

Thanks Jonathan, will do some digging.

Out in the sunshine yesterday and the speedo stopped reading for approx 1 mile. Flickered up & down a bit then started working again apparently normally. Presume it's an electronic version taking its message from a speed sensor on the rear wheel. Is the sensor about to through its hand in?

3M dual lock on front and back. Plates stay put, brilliant stuff and you can remove / replace them when ever you want to. Got mine from Amazon. Highly recommend it. Just make sure the surface is nice and clean. 

Does anyone have a set of S3 leather seats CW runners etc? reasonable nick required.
