Caterham owner two weeks now, first time driving the car the speedo was a bit bouncy The Caterham magic that every one talks about I thought, asked a few owners at the Caterham open day last week about it, the conclusion was a mixed bag when it comes to speedos. Then it stopped working altogether then it worked then gone again.

I know ,  looked it up on the Blatchat Tech page lots of information on the subject seems to be a common fault, although at first glance the abbreviations and general Caterham undercover code words took a while to work out as obviously people know the cars well, all new to me.

Ok, called around to find a garage near me (Bexhill) and nothing, the nearest to me was Caterham Gatwick, so called them to book it in, "we are booked up for the next 4-5 weeks they said as this is the busy season with racing and customers wanting to get their cars on the road".

Now this was the bit that amazed me " If I had one of our technicians speak to you, do you think you could fix the problem yourself" I couldn't believe what I was hearing, I cant imagine my Range Rover dealer saying that to me, loss of business etc.

Anyway, spoke with a Lady mechanic who was wonderful and over the phone relayed to me in great detail as to what needed doing, she made it so clear and me having not even looked under the car thought maybe I could do this. I have lifted the bonnet by the way.

Right lets have a go, went and bought a trolley jack, 2 axle stands,13mm spanner and a feeler gauge.

POSSIBLE FIX

Speedo Sensor needs adjustment:  FEELER GAUGE GAP NEEDS TO BE 1mm Or (0.0394 0f an inch with an imperial feeler gauge), the gap between the cog & the speed sensor needs setting correctly, adjust two locking nuts  using a 13mm spanner. The action all taking place under the drivers  rear wheel arch.

Mission accomplished, shocked myself surely now I am a true Caterham enthusiast.

Took it for a spin, speedo is no longer bouncing around its  now as smooth as clockwork, really enjoying the needle whizzing round, fast, but maybe just that little bit faster would be really great, I think they call it the Caterham catch.

Does  anyone have a really fast cat? please reply on blatchat?
