Hi.

We have a 500L (2014 - Just out of Manufacturer Warranty) and wondered if there are any known issues with the Dualogic Gearboxes. I rang a local dealer and they said there are no known issues or no software upgrades available but am not so sure!!

When driving sometimes it comes up with a red warning light with a massage along the lines of Auto Transmission failed. Check Manual or something like that. And it doesn't go into gear and just stays in Neutral.

After fiddling about with for a bit with some random series of events its fine again. This could be a simple restart or switch off, put in neutral start again etc. Not quite sure what the magic series of events is to get it going again.

Would appreciate any suggestions

Hi, :)
did you get the fault codes read after this..??:confused:

I suspect it's probably that the fluid level has dropped a little,
or it needs purging or air,
the purging can be done sat in the drivers seat:cool:

Hi Charlie.

Thanks for your input. Not in a position to get the codes read at the minute.

How can the air be purged and also how can we check the fluid levels and top up. I was under the impression these were sealed units. It is a 2014 Popstar model. (In the UK, just in case there are different ones in Europe or in the states.)

I'm not sure about what the actual fault could be, though I don't think the dealers response of there being 'no known faults' with the Dualogic gearbox is particularly honest - they can be a right pain, as the 500 section will show!

However, if the car's a 2014 example, whilst it'll be out of the 2 year manufacturer warranty, it should still be covered by the 3rd year. This is a 'dealer warranty' but it's essentially a continuation of the previous 2 years and you shouldn't expect problems being turned down for a warranty claim if the Dualogic gearbox has gone wrong. The only thing there might be a charge for is the diagnostic fee, usually about £70, which they'll refund if they find a fault which is to be covered under warranty. It's just the slightly a*se-about-face way Fiat deal with potential warranty claims, but might've come as a shock if you're used to other manufacturers!

I seem to remember particularly with the 2014 500Ls there were specific problems with the dualogic which required a recall and software update but could be wrong about the year.
