Revs Dip When Stopping

Hi all,

As per subject. Hot or cold, when ever I come to a stop the revs Dip and battery light flicks on for a second. As if its going to stall but doesn't. Revs then seem to settle after going up and down a few times.

Seperately, probably not linked but yellow parking light is on and been having several weird things happen lately like screen flicks on and off, radio resets. Occasional errors that come and go.

I've been thinking battery for a while now. Just an inkling but nowhere near certain.

Any thoughts please?

Thanks.

Brake light switch or rear brake light bulbs?- the brake light switch is more than just a switch, it sends messages to the engine ecu, for example when the brake peddle is operated it cuts the fuel supply to the engine Shocked
 It can when others can't,
It will when others won't,
It goes where others don't.

How old is your fuel filter?

Mine started doing the same and then started stalling when slowing down for junctions, very hair raising!

I foolishly hadn’t changed my fuel filter for a ‘few’ years (mainly cos it’s a pain). Changed it and all fine, lesson learnt.

Not checked CC but will do on way home tonight.

Not checked break lights but that is a good shout, thanks.

Not considered fuel filter either. Also good shout, thanks. Is that an easy change on a D3? I've had it a year now so no idea when it was last changed. Certainly not in my time.

I had similar, as above is your cruise control working and what about your EPB?

I had a problem with my EPB, it needed adjustment so I pulled the fuse for a few days. That fuse also took out the cruise control and the engine anti stall which caused similar almost stalling as you described.

EPB works fine but Yellow light is on and on screen error tells me there is an EPB fault. SO maybe it is all linked then?

Where about is the fuse for that? In which fuse box do you remember?

That's precisely why I asked about your cruise control. Rolling Eyes

Working or not?

You want fuse FL8, it's a big pink block fuse, it's in the engine bay fuse box, next to the battery.

Well I dont often use. Hardly ever in fact but the more I think back the more I seem to remember trying it a good few weeks back and thinking oh thats strange it isn't working.

Whats the diagnosis based on that?

Check fuse FL8 as described in my previous post. Wink

That fuse controls EPB but also sub-controls cruise and anti stall on manuals. Wink
You're experiencing issues with all 3 and that fuse is the common link.

Have you had the egr,s blanked ? Mine did exactly the same nearly stalled when you were coming to halt at roundabouts, traffic lights and the like.When Mick Flack did my belts and water pump he found that the butterfly valve had not been removed and when he did it cured it completely Thumbs Up
