Random Stalling Problem on Seat Arosa 1.4 Automatic

[pudgster]

Hi,

I have a problem with a Seat Arosa 1.4 8V Automatic.
The car is a 2000 W Plate with the engine code AKK. It has done 12000 miles.

The car has been in the garage numerous time, but nothing is coming up on diagnostics and when the car does stall in the garage it starts straigh back up. The car stalls about 2 times per hour if left to sit and idle.

Basically the car will stall at idle or cut out at any speed intermittanty. When it cuts out on the move it sometimes restarts, othertimes it dies all together with the oil pressure and battery light bleeping. The stall is very sudden, not juddery

When the car does cut out it often restarts straight away and other times it takes a minute until it restarts.

When it does not restart it just turns over at normal speed, The Tacho doe not move from 0 rpm. I checked for spark and there is no spark.
When it does work it drives perfectly fine throughout the rev range, no hesitation.
The stalling happens more frequently when coming to a stop or in traffic.
Some journeys are perfectly fine with problems at all. The problem seems to only occur when the engine has reached operating temperature.

The following have already been changed:
Fuel Pump
Coil Pack
The following have been checked for function:
Fuel Pump Relay.
Immobiliser
Earthing Cables
Throttle Body Cleaned and breather pipes

The Engine Management light is not lighting up, although I believe it may be faulty as it doesn't light up when the car is first switched on.

I hope someone can help.

Patrick

Yup I got all that ! and I think Im on an AKK engine not sure. Havent done anything about it yet as it seems to be ok at the moment. I have just found a decent garage locally to me who specialise in VAG engines and auto boxes so Im hoping to find something out. Will let you know as soon as I know anything hun.

just a thought, the problems you're seeing sound similair to the problems I had on my 1.0 16v Cordoba....

which was resolved by changing the ECU control relay.... which is a common problem on Mk3 Golfs etc.

It's only about £11 from VW

Not sure if your's is fitted with an ECU Control Relay or not, but definitely worth a look into.

 

[andyj]

just had a look on ETKA (VW Parts system) and it doesn't look like the Arosa was fitted with an ECU Control Relay......

have a look at the fuse/relay board under the dash, and see if any of the relays have '30' on the top of them......

 

[pudgster]

Thanks for your replies

The Arosa only appears to have two relays under the dash. That is the normal 53 relay and a 140 relay which turns on the fuel pump and injectors.

Today I am changing the Temperature Sender, and then the Crankshaft Sensor.

Mine did this for a while but its not an automatic.

It was a combination of a dirty throttle body and shaggged fuel pump.

And I thought it was the battery lol.

Your post states you have changed the fuel pump so I dunno what to suggest?

 

[pudgster]

Hi Ive changed the temperature sender and still having problems.

I am now going to change the dash clocks and hopefully this will fix the diagnostic lights and therefore the fault will come up.

The only other things I can think of are the crack sensor and cam sensor and the ECU!

I'll update you all, but please send your responses as they all help with my quest to fix this car.

Hi Pudgster,

Engine crank speed senders are very very common problem on these engines, when I worked for SEAT dealer, I must have changed at least 10. only other thing which can give a problem is the ignition coils, but by your description of the rev counter stays on 0 when cranking, I would still put my money on crank sender, as this is what gives signal to e.c.u for rev counter.

Hope you get it sorted.
Jochen.

Hi,

I have changed the crank sensor. On my automatic there seems to be two of them and they are both on the gearbox.

I changed them now, however with the sensors disconnected the engine still start... this has baffled me to whether they are the crank sensors.

Can anyone enlighten me where they think the crank sensor is on the 1.4 AKK automatic Arosa

 

[pudgster]

Hi I have just found out that the sensors I got from the motor factors was the Engine Speed Sensors.

Does anyone know where I can find the Crank Sensor???

 

[Jochen]

Hi,
Sounds like you have changed your gearbox engine speed sender.
The engine crank speed sender is located at the back of the engine, normally just under starter motor, gearbox side, it is held in by either a 4 or 5 mm allen key bolt. It is hard to see it as it is well tucked away. the wiring runs up by the thermostat housing and the connector is above the gearbox on a bracket.
Jochen.

 

[pudgster]

Thanks Jochen,

The garage couldn't even find the crank sensor and asked me to see if I could find it.

The multiplug was well hidden.

Car drives fine now,

however I changed the dash over and the check engine light still does not come on when the ignition is turned on or when a sensor is pulled.

Is this a simple problem or does it mean the ECU is dodgy?

Mk1 or Mk2? (square headlights or curvy?)

For some reason I don't have an engine checklight on mine, even though the handbook says I should

blown bulb or removed bulb...?

Hi,

I have a Mk1 model. I opened the dash cluster up and it uses an LED.

Then I purchased a new cluster from Seat and it still has no diagnostic light.

The light does not even come up if I disconnect sensors in the engine bay.

Hi,
The Mk1 arosa's do not have an engine diagnostic light in the uk market, just had a look at my mk1, the symbol can just be seen near the other warning lights, but it just was never wired up for uk market. Only the Mk2 arosa's had the managment light to comply with the more tight emmision laws introduced around 2002 ish.

it may be worth looking at the coolant temp sender

 

[Boo]

What engine code is yours ?

 

[roy thackray]

Poor running

I run a SEAT dealership in Croyde and found that one of the biggest problems with Arosa/Ibiza running problems, poor starting and stalling is the coolant temp sensor located on the side of the engine, make sure you replace the O ring aswel

 

[pudgster]

Mine was the AKK engine code and finally I have had it fixed.

It was the crank sensor (engine speed sensor)
What is interesting is that the diagnostics never ever picked up this fault.
