2004 1.4 MMT transmission intermittent failures - Jerry Attrick
I have owned the car from new and in the 4 plus years I have had gear failures four times. Each time it has righted itself after a time (From a few mins to an hour or so.)
The dash shows the N neutral setting but the car is in gear but this is not always the case. The local garage "updated" the gearbox under warranty just before it was 3yrs.
but no further information was given about the problem.The car was bought in Nov. 2004 and has a 1.4 diesel engine. I would like to know what is causing this.

Hi Jerry,
There were sadly a number of issues relating to the dreaded MMT system, I really need to know what has been done to the vehicle in the past, I may also need to know what ECU (part no printed on ecu) is fitted to your car, as well as any other countermeasures that may or may not have been fitted. I can find most of this from your vehicle reg number, although it's not a good idea to post it on here! Hmmm a tricky one, as I can't really give you my works Email address without giving the game away so to speak! You can however Email me on my private address, which is bladerunner042000@yahoo.co.uk
and i'll take a look at what I can find out for you. NB have you had any warning lamps illuminated on your dashboard at any time? Sadly I can't post all the answers on these boards as a lot of the info is 'strictly private and confidential' so I will have to email you direct with what I find.
Regards
Dave
