Engine Diagram

[bakes70]

Does anyone know were I can download a labelled engine diagram.

Also can anyone tell me were the fuel pump is on a RS4 Stagea? Are these know to cause problems.

I can answer the fuel pump location question. Thats if Series 1 and 2 are the same, I have a series 2.

Its in the bottom of the fuel tank, accessed under the right side 'boot' floor.

Remove the floor

Unscrew filler cap to release the pressure in the tank.

Undo the Sender and return lines. (watch out for the that'll come out) remember which is which!!!

unscrew the big cap over the tank and remove the centre piece(not sure its real name)

Put your hand straight down you should feel a small box, it has a little clip that holds it down inside the tank.

Unclip and pull it up, it will be full of fuel to becareful.

Inside this box is the fuel pump.

As for problems, it shouldnt be. There is a pump that is a direct replacement for the stock pump, I think its a Bosch one 040 maybe, fits the standard box and the plugs are also the same so no rewiring. My mate has the exact specs of the pump if you need it.

Hope that helps.

Bosch 040 is not a direct replacement for the Series 1. I have an 040 and i had to remove part of the cradel and modify the connectors for the power. it does fit nicely once done, but don't expect it to be a simple replacement.

Thanks for the info guys I am still unsure wether my problem is fuel related or electrical

what sort of diagram do you need? ECU wiring or something else?

and what is the problem?

My fuel pump is dying, symptom is pinging as it reaches full boost about 4500rpm and up.

I have a 1997 RS4 Stagea with 4 speed Auto. I have got a problem that when I cruise at 70km/hr or above the car seems to pulse. It does not do it when accelerating or when crusing below 70.

I have changed fuel filter, plugs and had checked the coil packs for resistance values and all seem ok. I done this as the fault seem to act like a miss fire. The car has been checked on a diagnostic tested and all fuel and engine management appear to be ok. I have the injectors cleaned and the gearbox flushed and new oil put in.

I had the auto box replaced and I am now wondering if the electrics / sensors on the auto box are causing the problem. I have been told the transmisson is ok. So I have narrowed problem to coil packs, but all the threads on here say there coil packs gave them a miss fire at 4000rpm or above were mine pulses at 2500rpm when crusing. The car does no do it under 60kph or when cold as I can drive the car at any speed for about 10 minuets without the pulsing. If it is not the coil packs the next thing I was thinking was fuel pump maybe, could a faulty airflow meter cause this?

I am getting the rear tyres replaced this weeks as they are shot and I will be getting the wheel alinament checked to see if this might be a cause.

Can anyone offer any advice or has anyone experinced a similar problem.

welll. generally engine problems relate to revs and chasis/suspension problems relate to speed. so if its only over 70klm regardless of gear, its probably the chasis.

I'm not really sure what you mean by pulsing but I would start with wheel balancing (not alignment) - could be an unbalanced or buckeled wheel? maybe tailshaft out of balance?
