Title: TD5 auto green lights M+S flashing
Post by: mike142sl on April 27, 2008, 21:03:20
On a few occasions recently I've noticed the green lights flash when I start the engine which indicates a fault with the transmission system - and it sticks in first. The manual suggests turning the engine off and on again which has cured the flashing. However today it took several attempts so I suspect it's a trip to the dealers next week.

Has anyone else had this, and if so what did it end up being?

Thanks

I had this when mine failed to start. In the end I changed the battery and there has been no repeat of the problem

I've had this a few times - although mine goes into 'limp home mode', which means the 'box sticks in 3rd. I noticed it more when starting to pull away on cold mornings - if I change from D to R too quickly, the 'box throws a wobbler. My guess is that on cold mornings, the ATF is a bit thick (is that possible ?) - I guess the other possibility is that the oil pump in the 'box may be a bit weak.

The Disco's in for the 108,000 service today - getting a new autobox filter fitted in case it's just a bit crudded up.

It does seem to be related to changing to R, especially just after setting off. But on Saturday it happened when the engine was warm and it took several attempts to get rid of it.

Well I got it back from the dealer today. It puts it in second gear apparently (limp mode).

The problem was a faulty gear selector switch which unfortunatley is not a DIY job as it needs matching with the electrickery, presumably via the test book. A pricey day with dealer labour prices, even with their allegiance discount ???

However the gear selector feels a bit better now - a bit more firm to the touch, so hopefully all will be well.

Hmmmmm, I think limp home mode is 3rd gear - but the stealer is *always* right !!

Where did you hear it was third?. Second would seem more likely :-k, it certainly felt like second to me the first time it did it, plus it would be a tall order in this part of Sheffield to hill start in third :shock:.

My RAVE cd IIRC !


Yep, found it -

Mechanical limp home
In the mechanical limp home mode, gear engagement is controlled by the manual valve. The gearbox is fixed in 4th
gear if the fault occurs while the vehicle is moving, or 3rd gear if the fault occurs while the vehicle is stationary. 3rd
gear is also engaged if a vehicle is brought to a stop and the selector lever is moved out of, and back into, D. Neutral
and reverse gear are also available.

Fortunately with mine, the battery was disconnected and reconnected and the fault, for the time being, has not returned.

I had a similar reprieve when my battery was replaced a few months ago. Of course as the problem turned out to be the selector switch it was purely coincidental and the problem returned after a several weeks, eventually getting worse to the point where turning it off didn't clear the fault.
