VW VENTO CUT OUT PROBLEMS

[mickylad]

I'AM HAVING BIG PROBLEMS WITH A 1997 1.9 VENTO TDI,THE ENGINE JUST DIE'S AT LOW REVS TRAFFIC LIGHTS ETC... 2 GARAGE'S HAVE HAD A LOOK ONE CLEANED THE CRANK SENSOR AND SAID IT IS THE IMMOBILISER AND A POSSIBLE RECODE ON THE KEY COSTING £75.00. IT CAN GO DAYS WITHOUT HAPPENING.WHEN IT HAPPENS IT CAN TAKE 5 TO 30 MINS TO START AGAIN.IF ANYBODY CAN HELP IT PLEASE LET ME KNOW.

check the relay plate under the dash,if it has relay with the numbers 109written on it,i would replace it, they hav been known to cause the problem you are having plus there no fault entry in the eng ecu with this fault.

Hi

Hope you can help as really do not know what to do next. I have had the same problem as you - my N reg Vento has been cutting out sporadically and then starting after 5 - 30 minutes. Changed HT Leads ignition module sparks etc etc but it has now cut out totally. The engine turns but does not start - any suggestion welcomed.

Cheers

Sam

hello all

having same problems i have a 96 2.0l gl auto vento that just cuts out when im driving when its idling and when your trying to start /crank the engine... not showing any fault codes... the fuel pump relay was clicking and the rev counter drops dramaticly... changed fuel filter and changed relay ...which done nothing... now im having trouble starting it (it cuts as soon as it starts) but leave it 10 mins and it fires up fine i can go a few miles before it starts freakin out....

read an article where a guy had a similar problem the garage told him it was the crankspeed sensor he replaced it twice... then tried the power relay to the ecu and all seemed fine....

have been spending hrs searching for answers all over the net with limited success but it seems to be a common fault with the vw

looking forward to answers please...!!!!

Hi Guys,

I had the same problem with my partners car, and I found I could get it working wiggling the fuse board.

In the end I changed the relay Paulb mentioned and guess what..... it works!!! SO if you having this problem this is the first place to start and especially the relays are only a couple of quid.

Good luck guys and hope you sort the problems, now just back to sorting my current problem.

[smokey0123]

I have to agrre with paul on the relay, it is very unlikely to be an immobiliser prob as it only checks all is present and correct when you start up.

Just Brought The New Ecu Power Relay..........

Guess What It Dosent't Work....... F~@ck F~@ck F~@ck....
Had To Get The R.a.c Out....first Of All The Mech. Said It Was The Ignition Plug....wrong..
Then Said The Dizzy Is Giving Out A Strange Spark, As In It Was Cutting Out Then Back In.. He Suggested Getting The Thing Tested....
I Think It May Be My Fuel Pump,as The Power Stays On Ie The Lights And Dials,only The Engine Cuts And The Fuel Pump Relay Clicks Like Mad... Or...

Could It Be The Crank Speed Sensor....... !!!!

Any One Have Any More Good Advice

I had the problem were my 1996 2.0 Vento would cut out whilst driving and wouldn't start until one of the relays reset itself which could be over 10 minutes. The relay was changed and have had no problems since.

On the other hand i do have another issue and this is were my Vento is coming to a stop or changing down gears. The revs suddenly drop below idle and can cut out (unless i save it by pressing the accelerator which can be tricky when one foot on the clutch and one on the break). I can stop this from happening by bringing the car revs down to idle whilst still in gear and then change but if my revs are above 1000 rpm the chances of it cutting out are high. It starts up no problem if cuts out but is annoying (especially as i'm trying to sell it now). It only has 76,000 miles on the clock but i only do 5,000 miles a year - could it be a clogged up engine as not driven all the time??? Any suggestions??? Thanks.

Hi guys, I've got this one too on the same 96 2.0L vento. I had a diagnostic run at my local dealer who said nothing was wrong but it's getting worse. I've had some suggestions that it may be the MAF sensor but disconecting it causes the engine to stall more easily so I'm guessing not. Crank speed sensor makes some sense so I may look into that.
Mine does around 300 miles a week so it ain't lack of use.
Sorry for comming in and asking difficult nooby questions but any help would be gratefully recieved

[MarkB1979]

I'm so glad I'm not the only one having problems on this front.

I've got a 2.0l GL model, only 60K on the clock and it cuts out when dipping the clutch when coming to a halt. It's sporadic as well like yourselves. Revs drop to 400-600 revs and then it cuts, but then other times it drops that low, but manages to pull itself back.
I haven't had the problem of it taking 10 - 30 mins to start again though. I can get it to start again pretty much straight away.
Engine's been serviced, dropped slick 50 into it, changed distributor as well. Was thinking of getting K&N as well to help engine breathing.
Not sure if it's worth changing relay going on prev comments.

Anyone got any more suggestions or is it something we vento drivers are going to have to put up with.

[gruffly]

Looks like it's just us, with nearly 450 viewings and no answers this must be a new one on here. I'm going to start pulling out and cleaning or replacing sensors and see what happens.
I'll post up here if I get anywhere.

[forevervento]

Yeah it seems like a normal problem but if we just knew what the solution was we could enjoy driving again without trying to keep the engine running everytime you change gear :mad:

I am trying to sell my car at the moment but not due to its fault but because i hardly use it and don't need the additional running costs. I'm going to struggle selling it if it has this problem.

Would really appreciate it if you find the solution :biglaugh:

Cheers!:beerchug:

[91oldskoolsoldi]

:biglaugh:fingers crossed i have solved my problem...!!!!!!:biglaugh:

changed relay 30 e.c.m and it didnt make a difference...#
was ready to get new dizzy... i have 104k on the clock now i brought the car 2 yrs it only had 62k on the clock..

mines a N reg (96 registered) ady engine.. 2.0GL.. auto box...

after checking the E.S.S (engine speed sensor) discovered the wires had perished..
the outer casing was gone in places exsposing the 3 wires inside, which were also without their casings and bare wires were touching..

replacing was a pain though, as the fixing hex bolt is located behind the engine mount, as you look at it its just to the right of the oil filter.
and i suppose the heat of the engine hasf#cked the cable..:zx11:

anyway changed the cable and all is fine again.. (it did cut out on start up for aa sec. after about 4hrs of driving around but that was a while a go and has'nt done it since) just a glitch i think.!:o

seems a stupid place to run a cable.. :(

anyway hope this helps will try and get photo's uploaded but dont bet on it .....lol

[forevervento]

Typical! Just sold my car now. :zx11:
Would've liked to have had that fixed before selling it (and got more cash for my car) :D but hey %$^& happens!

Thanks for the reply and good luck with it.

I'm signing off for good.

Cheers! :beerchug:

[91oldskoolsoldi]

still all good......

working fine no problems

[gruffly]

The ess is in deed a swine to get to, just done it and no joy.
I'll change the ECU relay tomorrow and hope that sorts it.
It's good to hear some people have fixed it, it's ******* me off in quite a big way :zx11:

[HankBoogie]

I have the same problem with my 1997 VW Vento GL 1.6. It shuts down all of a sudden and doesn't start up again unless I let it cool down for five minutes or so.. I looked in the relay box and I didn't see any relay marked 109.. I cant find any schematics online so I don't know wich one to change.. anyone got some ideas here?

[gruffly]

Ok I finally got mine sorted, I flushed out a lot of gunge from the throttle mechanism and reseated a loose relay ( 30, ecu relay ) and disconected the battery to reset the ecu (duh, turn it off and back on again works for all other electrical things). Now all running smoothly and not stalling, choking or bogging down, producing no smoke and burning less fuel.
Thanks for the tips, signing off for now

[rambogolf]

ok mine has the same problems as described.. its an early one (94), so i think i can rule out the coded key and ecu problems, but would it have a crank speed sensor as its only a 1.6 single point injection. anyone know the answer? this vento cant die :D

Looks like you've done what has cost me £40! Finally had enough of it stalling on me so had an auto tune guy come out. He ended up cleaning out the throttle motor and then said he'd reset the throttle motor with his VAG info.
Just wish I'd checked this because if all I needed to do was disconnect the battery I'd be £40 better off!
Oh well, am glad it's all sorted now at least.

[leggy_vento]

ive just baught a fuel pump for my problem listed above. ill let people know if its resolved :Blush:

[vento4life]

I had the same problem with my 1.8CL vento, It turned out to be the matrix heater, hope that helps CP.

[leggy_vento]

he matrix used to make the car cut out as we've described? hmm not heard of this problem. do u know how it caused it? let hope its the fuel pump as im waiting for my new one to arrive.

[leggy_vento]

ok well the fuel pump arrived. i did 1 last test before swapping it, and when i went out tot he car it wouldnt start at all, i had my dad in the boot to here if the pump was priming whist i turned the ignition and there was nothing, so i swapped the fuel pump relay(although that was the first thing i did after reading this thread) with the one from my mk2 golf and it instantly started working. done 100 miles odd around town with no probs so far. so a tip to anyone having simlar issues is try 2 relays;)

[fil1973]

father in law had similar probs with his vento 2.0 GL 8v (2E engine)

turned out to be the ignition coil (breaking down when hot)

and sometimes the car would not start at all & that was the crank sensor,

but as we all know the crank sensor on the 2.0 8v is incorporated into the
distributor so we had to search the whole of the north east for a replacement

after that though the vento ran perfect,

Hi,

I've been having the same problem with my A6 2.5 tdi V6 SE. It just cuts out as your driving along normally. It usually restarts straight away, but it is a MASSIVE pain in the @rse.

Took it to my local deisel specialist. He plugged it in, read the fault code, turns out to be a faulty engine speed sensor in the injection pump. He even read the fault code from the injection pump itself just confirm the fault, it was correct.

So, its going in tomorrow, gonna cost about £600 to get it sorted........

GUTTED........

[duanvogel]

My Vento TDI had the same cut out problems. after replacing the 109 relay, all CUT OUT problems where something of the past.!!
THANKS

[Little_vento]

Hello guys! I have a problem with my Vento, when I start the car when the engine is cold, it works perfectly, but if the motor is hot and I turn it off, when I start it again, the car goes max to 110-120km/h. It's like it does not get enough airflow. I put the car on a tester and it said that the debitmetter is fault, but I've changed the debitmetter and same situation.
Do you have an idea on what the problem could be? Thank you very much!

[mickylad]

Thanks it was the relay switch in the end cost £50 a lot but it worked fine after that the garage told me it was common on Ventos and golf mk4s ....

You will get a much better response if you start your own thread, tacking onto 12 year old threads means people my miss you.
