TD4 auto strange cut out problem

Hello all,

Right, this is a strange problem.

I have a 2006 TD4 auto, its done 70k has a full main dealer service history and runs just fine. The only thing that needs doing is the VCU support bearings as am getting a slight rumble so have just ordered some OEM ones. VCU is fine as it will reverse in circles all day with no throttle on full lock. Plan to do gearbox and ird oil change soon, and fit some new pads. Did the PCV filter a couple of months ago.

However, we have come accross a really strange problem where by it cuts out either just after starting or when just about to reverse. It is strange as the ONLY time it ever does it in in the wife's work car park, it NEVER does it anywhere else. Weve just been up to Lancashire / Yorkshire from Devon and it didn't miss a beat or cut out once. We've been testing it for the last few months and cannot make it cut out anywhere else.

After it cuts out it starts again and runs normally just fine. More often than not it does it after starting rather than when reversing. It doesn't happen every day.

The only thing I can think of is that its something to do with the immobiliser, perhaps some kind of interference??

Any ideas?

I sometimes have the same problem, and have always put it down to a cold engine. With mine it is always in winter or on cold mornings very rarely in summer. The engine has done it since I've owned the car. I think it might be something to do with a slight down gradient in front of my house causing it. It has happened to me for years so I don't think it is anything to worry about.

Thanks very much for the reply. Interesting ours never does it when parked on a gradient. Our drive slopes slightly and when its been parked on that, its fine. Its started to happen less since the weather has got colder.

It also never does it when I use it, only when my wife does, hmmmm!

Agree that its not much to worry about, will keep an eye on it. If anything changes will post on here.

either do not go to the wife's works car park or have a look around and near to the car park it is a long shot But is there a police station or similar very close by as radio transmit ions can have weird effects .

Our local cab rank has a similar effect

Good thought, I think there might be a phone mast quite close by, will have a look. Its not done it all this week.
