Hi Paul,

Without seeing the car for ourselves it's hard to say for sure. The gearbox itself could be leaking oil somehow, though it may also mean the failure of the rear crankshaft oil seal on the engine. Both of those are likely to be expensive repairs so make sure you get to the bottom of it before you buy the car.

Let us know how you get on.

Hi Sandra,

The Stilo is well known for its electrical gremlins I'm afraid and it's impossible to diagnose from afar. Even a good automotive electrician may not easily trace the source of your woes. In this instance we'd advise you to bring the car to a Fiat main dealer, as they will have seen the symptoms before and should quickly get to the root of the problem.

It's likely that there's an issue with the car's wiring loom, which is difficult to pinpoint.

Sorry not to be of more assistance.

Hi John,

I put your question to Paul Healy, our News Editor, but also a very experienced man in the way of Japanese imports. Here's his response:

May we first commend you on your choice of choice of cars? There is little that can offer the kind of thrills the MX-5/Eunos Roadster does for the money.

In regards to your question; yes the Eunos Roadster is essentially just a Japanese Domestic Market (JDM) MX-5, but there are a few differences between the two cars. For the most part these are cosmetic or inconsequential differences such as the shape of the number plate surround or the fact that the speedometer will be in km/h instead of mph (which is actually handier). The bigger issues relate to the likes of the thinner windscreen that would require a new surround rubber should you need to replace it with one from a MX-5 and also the engine management system (ECU) differs between the cars, but failure of this system is rare so the likelihood of it being a problem is minimal.

While air conditioning was offered on both models many MX-5s do not have it whereas most Eunos Roadsters do. This means that the power steering belt that would also drive the air conditioning compressor will be different between the two cars. So too will be the radiator, as the Eunos almost certainly (the Japanese like their air conditioning) will have additional mounting points for the unit.

None of these issues present any real problem though. Such is the appeal of the MX-5/Eunos Roadster that a whole industry has sprung up to supply parts for both cars that are sometimes unavailable through official channels. Websites such as mx5parts.co.uk and mx5ireland.com are good resources.

Hope this helps!

Hi Paddy,

This really sounds like a clutch failure. Many cars have hydraulic clutch mechanisms, which is why you may still get the feeling that the clutch is ok. However, it could be that a driveshaft or a part of the gearbox has failed. It's highly likely it's 'just' the clutch though.

Bring the car along to a mechanic to get it checked out.

Hi Jim,

Sorry for the delay in getting back to you, but I was checking this out and there certainly seems to be something of a difficulty with the diesel particulate filter in the Mazda6 although in general Mazda cars are really very good. There is ancedotal evidence of problems with the DPF and we have had questions on the site from owners relating to this, who were seeking to remove it altogether. With any used car it is pretty impossible to predict if the issue will occur so perhaps it might be worth considering another model, which is a shame, because the Mazda6 is a really good car otherwise.

Here is some more info, from a Mazda6 forum.

Hello Mark,

We checked in with the technical department of Fiat Auto Ireland and they told us the following:

"First have the air bag system checked with a Fiat Dealer to see what errors are present and they will advise on the repair. The problem could be with any part on the system so this check at the Dealer will save you time and money."

Hope this answers your question Mark.
