Title: Grumpy Diesel getting silly now... :-(
Post by: Diamond Black Geezer on 10 December 2014, 16:43:37
Suspect my lift pump is on the way out, and when I get half a chance, I will do it (though the weather's not provoking me to do it any time soon)

However, now I've got the issue that the revs seem to dive by about 200rpm when I change from P to D... doesn't matter if I have load like heated seats, lights, blowers etc. or not. and as the tickover has always been a shade slow on this thing, on about 5 occasions in the last week or so, the engine has stalled. Pretty embarrassing and annoying stuff at traffic lights, as you can imagine. First time it happened I was making a relatively tight turn from a standstill, and the subsequent power sapping caused by the PAS pump caused it. But now it's to the point where every single time I am about to engage D I'm praying it will engage ok. Resorting to leaving it in D at lights + footbrake but I don't like dazzling drivers behind me, it annoys me when people do it.

All I can observe is that it hasn't done it in Sport mode...yet. Also, immediately after starting up, when idling at approx 900rpm (before warmed up) there appears to be no appreciable drop in revs at all when I move from P to D.

Oh, and while sat on the house front, waiting for my other half to appear, on her emergence, I blipped the throttle - whereupon the engine just died.

Is this all related to lift pump - or is there an expensive gearbox issue going on here?

Merry Christmas!!  :y

I have no useful advice really other than:

Resorting to leaving it in D at lights + footbrake but I don't like dazzling drivers behind me, it annoys me when people do it.

I used to leave mine in D and pull the handbrake on.. saves dazzling and you don't creep forward.

I must confess I don't find brake lights bright enough to be dazzling, even at my advanced age, certainly not as bad as low sun this time of year. ??? :y

Sorry, also meant to say, I assume you have checked all the usual suspects, gearbox oil level, and gear selector.?

To be honest, boys, all my free time is spent doing freelance design work, and working on getting the V6 going. I don't like leaving cars unmaintained like this, but every minute i spend on the turbo weasel literally has to come from somewhere, be it less time on my beautiful V6s resurrection or less time with my girlfriend or the graphics work, all of which I love doing.

Will have a look at oil level / selector - that's a good thought, didnt think of them.  :y

  Instead of putting it into P, why not do N and use the handbrake? you may be able to very slightly pick the revs up when dropping back into D

Also the handbrake is the most ineffectual I have ever known on a car (yet passed the MoT).... also slightly surprised the cure suggested by you chaps for a car which stalls when moving from P to Drive is 'leave it in Drive'   :y

I'll certainly try altering my driving style for the near future. At least get Christmas out the way, then make use of my Halfrauds socket set I'm getting  :y :y

What Keith is suggesting is a variation of the 'rocking' procedure, as described in the manual, for moving away if stuck in snow or mud :y

In Neutral you can start and switch off the engine, so leave the car in Park when not in use, but to go somewhere, try:

Ignition on.
Left foot hard on brake.
Into Neutral.
Start car.
Bring the revs upto 1200 with right foot.
Choose a gear.
Hand brake off.
Gently release foot brake.
Move  away.

Find somewhere quiet, empty and free from posts to practice before using it as a daily solution, and if it all starts to go Pete Tong, simply knock it into neutral :y
