Holding revs between gear changes
A friend has a 2.4tdci and between gear changes, more noticeable between 3rd to 4th the revs don't appear to be dropping, i.e staying high as if the foot has not be taken off the pedal.

Any thoughts? I was thinking switch on the clutch pedal? 1999 Defender TD5 110

I thought that this was just one of those thing, some do it all the time , others don't and some do some of the time.
Mine will do it one day then has a break of 3 or 4 months , or it does it for a week and then has a break.
I have spoken with main dealers and Independent garages they all know about it, do not know what causes it or how it can be stopped. Don't make old people mad.
We don't like being old in the first place,
so it doesn't take much to Censored us off.

2.2 is known for this but not the 2.4.

It is indeed possible that the clutch pedal switch is the culprit, and it is at least quite easy to test.

In fact ours are developinng the opposite. Some times when the gear change, revs goes up for 1 sec and then drops...
Until now doens't means any problem. I will check the clutch pedal switch (I have to change the cylinder anyway)

I have the same problem and also no solution from the people who should know. Iam going to try changing both clutch and brake switches when they turn up. Have thought this could be linked to the anti stall system??
Thank
Garry

My 2.2 has done this from new (year old nearly). Does it everyday mainly between 3rd and 4th. I've just learnt to live with it.

Check the pressure sensor on top of the clutch master cylinder. I know (well, 'heard') that when the clutch is depressed it sends a signal to the ECU to reduce RPM... Could be something there Wink

I had a faulty clutch switch on my 2.4 Puma. The ECU thought that the clutch was constantly depressed and therefore wouldn't allow the revs to exceed 3000rpm. It didn't maintain the engine speed the way you're describing though.

Incidently, I found that the switch for the Puma and for the TD5 are opposite throw (one is normally open going closed, the other is normally closed going open), so make sure you have the right one.

Issue resolved - by replacing the clutch switch.

Thanks all. 1999 Defender TD5 110
