Scotland 2005 Discovery 3 TDV6 HSE Manual Zambezi SilverDiscovery 3
Revs Dropping

Hi All
Can anyone help me with this Ive got an 05 HSE D3 manual and first thing in the morning when I start the car and drive away I get to the first road junction and slow down the revs suddenly drop and the battery light appears for a split second like it is going to stall then the revs come up again and all is okay,
It dosnt do it when its warm everything is fine and its not EGRs cause they have both been done.It has also had a brand new battery, its just a pain every now an again cause it keeps stalling
Im running out of ideas.
 Mike

My original D3 (54 plate 05 model) used to do that every day. It did it from new, and never got any worse. Despite several 'software' upgrades it was always the same. It never caused me any problems in 125k miles so I would not worry.

FYI my newer 58 plate 08.5 model does not do it ever!

My 05 model does the same thing, but you'll find that it will only do it in cold weather. As soon as spring/summer comes it will stop till next winter. I understand that its a software thing that L/R have never got to the bottom of.

2005 Discovery 3 TDV6 Base 7 Seat Manual Bonatti GreyDiscovery 3

How did you decide the throttle body was the cause , did a fault code register ?

I have the same issue from cold starting , below approx 5 degrees. on my 05 plate.

Fault was diagnosed by dealer as clutch drag , flywheel was found to have excessive movement and replaced together with clutch assy (2nd time in 43K miles) , thankfully under extended warranty. Previous attempts to fix included glow plugs and injector replacement.

However this has not resolved the problem and now looking for any leads into other causes.

Any help would be much appreciated.
