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 ! :driver:
:sad1:
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...
:happy2:

Ohh, interesting. Mine doesn't self rev but that's interesting getting the same. Take it no adverse consequences?!
Pop over and I will take a look.
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. :happy2:
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. :sick:
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 :happy2:
-
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. :rolleye:
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.
-
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!
-
Neil, try replacing the G410 sensor on the side of the fuel pump.
Cheers Alex :happy2: 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 :sad1:

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?

:confused:
-
Seen that a few times with that o ring.
Try a g valve.
-
What are we looking at here Alex?
-
The O-Ring on top of the Piston, has a part missing :sad1: Will try the rev G on, could something so simple cause the problem, of it dropping down on the rev's so far it cuts out?
:happy2:
-
Well my issue isn't fixed either. Didn't have any problems for month and then twice in 30 minutes, although once again it was under boost!
Doesn't help but interesting nonetheless!

:happy2:
So is that an opened Forge DV I'm looking at Neil?
-
Yes Ayoub, that's were the spring goes, with the top/lid beside it :happy2:

:happy2:
Have you rung Forge, explained your problem and asked for a service kit?
iirc it includes a new rubber O-ring, new piston and some grease and they sent it out for free a while back.
-
Yes emailed them today, with the pictures, still waiting to hear back, be early next week i would assume :happy2:
A service kit would be useful !
-
Well tried the OEM pcv on today, trying to rule things out... Didn't fix it, Like the pcv fix much better. I did the dipstick test and idle went funky, i did test the pcv first, that just double told me it was ok.
Anyways when i took it of, i found some of this :-

-
From what i'm aware this can be down to the weather, or cold/war air causing moisture...
Maybe a new gasket for the PCV fix and a good run!
:confused:
Could a boost leak cause this to happen?
-
Mine looks like that all the time, is the under side of your oil cap like that? Short journeys is all I do and its like that.
-
When the car died... did all the clocks drop to zero too??

Hey matey
no no, the odd time i would get the milky stuff round the oil cap, but thats only on short journeys, most the other times i check it clean.
car getss serviced every 4-5k miles, always used castrol 5 - 30.
Always geniune parts.
I did clean it the other day, then checked angain the day after, it was not anywhere near as bad, so i will run it for a week and then check and again 2 weeks after that...
Anywhere i have read about this, it seems to be the cold weather, with the cold weather in, i would not get on, many longer journeys, maybe just needs a good run...
When the car died... did all the clocks drop to zero too??
Yes rich, when the car goes to die off, the revs bounce, splutters, then just stops, the battery light then comes on, which gives me the indictation to bump start it to keep on the move, if need be...
:happy2:
hope you understand the way i have explained this???? :fighting2: :signLOL:

Just thought I'd mention as my PCV looked like that till I removed it and fitted a catch can. Still get that sh1te everywhere tho, but I just give it a decent run and it goes. Don't think it's anything to do with your other fault. Hope you get to the bottom of it.
Could it be a dodgy earth / ground point or a bad battery?
-
:happy2:
Yes when i had run the catchcan, i noticed it was the same, the hoses used to be filled with all that gunk, aswell as the catch can... :sick:
As for a dodgy earth, where do i start looking ????
It's not something i have had to do before! :laugh:
:popcornsoda:
-
Sure I read that Nick from R-Tech had an ongoing fault with a MK5 and had to check all the earth points and made the comment there were loads lol!
Start closes to the battery, then just tighten up everyone you see in the engine bay, might be nothing to do with it but if the clocks are dropping and battery light flashing, thought it might be worth a try
-
What plugs are you currently running Neil?
-
Same happened to my scopes the other day. Car had not been out for a few days and it didn't like being give full throttle. Power cut and out clocks dropped for a split second and then came back on again. :scared:

Cheers matey, it is something I will have to look into, if I remember right, someone had posted up all the earth points, as they thought that was causing a problem they had...
:happy2:
-
What plugs are you currently running Neil?
Hey Alex
New OEM plugs fitted (2000) approx, miles ago, changed from Nology plugs as they where throwing up a fault with the intake runner, as soon as the OEM plugs were fitted the faults cleared all was good then.
:happy2:Same happened to my scopes the other day. Car had not been out for a few days and it didn't like being give full throttle. Power cut and out clocks dropped for a split second and then came back on again. :scared:
Was it like, the rev needle was bouncing then going to cut out?
-
When the car died... did all the clocks drop to zero too??
Was out testing there now, the only needle that drops is the RPM one, the rest stay up, the speedo tells me my speed ok, fuel gauge ok, plus temp gauge ok...
Is there any logs I can run for testing or to rule anything out, any basic settings needing done?
I now have a stinking smell that blows the heaters when the car is stopped, but seems ok when driving!
Only from the weekend have I started to notice this.
:sad1: :sad1: :sad1: :sad1: :sad1: :sad1: :sad1:
I find the car is driving the very best bar these few problems :signLOL:
At my wits end guys, just not to sure where to start now! :fighting:
All help is gratefully appreciated :notworthy:
-
It didn't bounce... It was like I had turned the ignition off and back on. No fault codes stored
-
Mine it still doing it. Gets to 5000 rpm and sh*ts it's pants. An error has been thrown up for the engine speed sensor.
-
Could a faulty downpipe lambda sensor cause any of these problems????
-
Could a faulty downpipe lambda sensor cause any of these problems????
Highly unlikely Neil. Also a bad lambda sensor should give a fault code on vcds scanning.
-
ive had it on a few tuned 2.0 tfsi usually when pulling upto a stop

I was thinking that too matey :happy2: Just trying to rule things out, anyone have a approx. price of a new one...
Also found out what the smell was when the heaters were on, some grease on my engine block :confused: all cleaned of and smelling fresh again ! :smiley:
So that's one problem down.... :star:
ive had it on a few tuned 2.0 tfsi usually when pulling upto a stop
Yes matey, that's exactly when mine happens, when the car is coming down of boost, not even from when an extremely large amount of boost has been given, just a blip, if I hold the clutch down when coming to a stop, that's when the rev drop/bounce, then the revs must drop to a degree where it stalls or cuts power...
Any idea, what caused it Pikey?
-
New one is around £150 from VW.
ECP do the same one, a Bosch for 134 notes.

-
The difference between the two is?
just the brand name?

Bosch supplies VW with the lambda sensor. There is a slight superficial cosmetic difference between the two but the sensor is identical. I should know as I'm using the Bosch one. :smiley:

Cheers Ayoub :drinking: will look into this first before thinking about changing!
Well today, I started of with a simple boost/vacuum leak test, the objective was to find bubbles from where I had sprayed the different parts with soapy water, no bubbles, none seemed to be sucked away either, I replaced the PCV gasket, nice new one in there now, replaced all the boost hoses in around the DV, serviced the DV, some fresh forge grease in, added a custom spacer in, only cost 10p, so thought I would try it, re-fitted the throttle body hose, as I was not 100% happy with the fit, clips all tightened up, replaced the MAF sensor with a spare I had, scanned and out for a test drive, I have to say the car drives great :driver: love it... But problem still there!
The next thing I would like to try, is cleaning the throttle-body flap, what would be the best to use?
My idle seems to tick over between 720-760 rpm's, can this be adjusted in anyway?
Thanks
-
afaik there's no way to alter the idle speed even with vcds.
-
Engine speed sensor.
-
Engine speed sensor.
Does or can this adjust idle speed??????
-

Nope. It reads the speed. The idle is in the mapping.
Get rid of the forge valve and try a rev G. Could also be a small leak from the brake servo pipes.
-
cheers Al
Will give that a try :happy2: Also where would be a good place to start searching for any leaks from the brake servo pipes ???
-
Probably cheaper to just get a new hose if there is any doubts for just under £29. And you will need the small green plastic bung as well if you get a new hose part # 056129777

Thanks Ayoub, what can cause these to leak, would they be known to failure ?
-
Anyone ever figure this out yet as the problem is still here...
