Engine shut down under boost - fail safe?

[jonnym]

Over the last week, my golf has been driven hard. Probably very hard, red lining, aggressive down shifts etc etc you get the picture.

My golf on four occassions has cut out with the battery symbol showing on the dash. General it's either when i'm slowing from high speed and/or in neutral rolling to traffic lights/obstruction. I initially thought it was me stalling it as I was still getting used to  the new clutch, but now driving over 1000 miles with it and pretty much got the grip of it.

Restarting the golf works fine and off we go again. No issues. I can't help but think it's a fail safe, but never had this happen before. Doesn't seem to have had any impact but just be interesting to see if others have had similar.

Dsg or manual?

Pop over and I will take a look.

What could it be, my car is doing the exact same thing ! 


 

It is also "self revving" when the clutch is pressed in, it doesn't rev past 1.5 - 2.0 rpms, just curious as to what could cause it to happen...

Ohh, interesting. Mine doesn't self rev but that's interesting getting the same. Take it no adverse consequences?!

Ahh I would!! I'm away in Manchester 11th jan, but apart from the run up and down, won't be driving much so touch wood will be fine. I'll phone you today/tomorrow as I need to come up anyway! :)

Mine is manual also. 

I haven't noticed any adverse consequences, just the fact when your approaching a junction, maybe with the chance to continue on, as the road is clear, to find you have lost all power, no power steering nothing. 

Just don't take the chance, seems to be ok when your on the power...

It seems like it could be too much fuel, IMO !

Any help would be great

This happened to me when the throttle body was giving up.

Car just stalled out of no where then slowly it got worse and epc and traction control light on  with revs jumping up/down

Hope you get it sorted mate

Not long had a new rev Q throttle body fitted !

Neil, try replacing the G410 sensor on the side of the fuel pump.

Well I didn't have any of that but lol nooo can't be the throttle body! Although my car has been running perfect for too long long, suspiciously long. I sense it is plotting something :/

Just getting none of the symptoms. We'll sort it out! Alex when you back in work??

We had a Tiguan which did that, ended up being water ingress into the wiring loom.

When my TB failed on the GTI it felt like I'd hit a brick wall and the EPC light came on with reduced power.  Started fine and didn't kill -9... sounds bloody dangerous to be cutting out like that.

[jonnym]

Hmmm thanks. I am intrigued but tbh not overly concerned atm. Least I'm not driving it for a while. Need to pop to Blackburn from Manchester but I expect no issues as I won't be driving agressively!

I'll get sorted. Just wierd, so happened for over 2 months, yet to deterioration, and had work done since first happening again.

I also wouldn't have mentioned it but the last time it did get me thinking!

Cheers Alex    ordered the new sensor, so i will try it as soon as it is here !

Tried replacing the fuel pump G410 sensor, but still cutting out

Hi Guys

Bringing this back up, still have not got to find out where or what the problem is, could it be a vacuum leak, faulty sensor, had a leaking twintercooler pipe gasket, a while back, could there be a chance oil/fluid has reached the throttle body and the flapper needs cleaned?

Had read somewhere, they had the same problem and turned out to be the DV, so was going to try a rev G on.

What would your thoughts be on REV G over the forge dv?
