90% of leaking mx5 soft tops can be cures with one very simple replacement part, the plastic catch cap.
Water creeps in through cracks in these and will fill up the seals. Once the seal gets over full it will leak straight into the car, usually all over the seat or the footwell (a huge cause of ECU failure).
Replacing these caps if they look cracked or are missing is vital.

How to run the diagnostics on a Mazda MX5 MK1
Some of these codes are common with MK2s BUT haven’t checked them yet.
There are a few things you need before you start:
- A jumper – this can be as simple as a paper clip
- An LED – ideally one you can actual see
- The ability to count! If you can’t count then you shouldn’t be trying this!

A fairly common problem MX5 owners find is that one of their doors will fail to open. Try all you like with wither the interior door handle or exterior and it will still not open.
Don't worry, there is a solution.

We are often asked, "What does the HEAT light mean on my dashboard?"
There is a thermal fuse in the catalytic converter of a MK1 imported Eunos Roadster. If it overheats the HEAT light will illuminate. Usually this is caused by a miss-fire.
An annoying tick?

Whats ticking ?
A very common mx5 problem is the development of a nasty ticking sound from the top end of the engine. Usually the first signs of this are when started from cold, but similarly the problem can be non-existent when cold, but appear after the engine has been given a good workout.
99% of the time the problem can be put down to the Hydraulic Lash Adjusters (HLA's) which are used in place of a more common solid lifter with shims (as found in the later mk2 cylinder heads).
