Sound like the idle air control valve(IAC) is dodge, could try taking off and cleaning with carb cleaner, while doing that take off hose by throttle body and also clean in there inc butterfly, go and give it a good blast down the motorway !!

Hi i have an intermittent starting problem on my 2005 Volvo s40 1.8.

We don't have the 1.8 engine here, but the diagram for the 2.4 engine is at the link below. They should be similar.

Isuzu 3.1. turbo diesel. Engine revs drops and the engine cuts out intermittantly on tick over.

possibly the fuel metering solenoid on the injector pump playing up was common
or injector pump itself
depending on which type of injector pump you have the round switch things on top rear section of pump that have a single or 2 wires to it.

Volvo s40 engine ticks, revs and cuts out

goodday! I asked a question about my S40 Volvo 2001 high idle. The answer is great, but I did not use it because I found out that it the car was giving another fault.

there are times when the engine woulld crank for a long time without firirng. when it finally does it would be powerless to an extent that it doesn't respond to the gas padel. its like it activates some form of inhibitor. When it behaves like that the only way to eventually start it is to disconnect the battery and wait for a few seconds. Now I wonder if it is still the idle motor

When I go 3000 rpm the aceleration is not good. What would it be?

MAFS are common on Volvo especially the ones using the Renault engines. Could also be a TPS fault, you need it putting on a data-reader to explore the values in live data whilst taking it up over 3000rpm. The fault will be highlighted.

When the accelerator on my 2 litre 1997 volvo S40 is pressed quickly it splutters and won't take the revs. Any suggestions?

check your spark plugs first,and then have your coils checked,might be a misfire or flat spot,and also check that your throttle body is clean

Flashing upside down arrow/ slow acceleration

This is a common problem of Volvo S40. You can try this trick to turn off the flashing arrow light.

1) Turn off Engine
2) Turn key to "On" position (Not start the engine), you will see the panel light will on
3) Step on the break paddle
4) Shift the gear from "P" to "L" 10 times
5) Turn key to " Off" position
6) Now you can start the engine.
7) If doesn't work, you can repeat the procedure.

Hope this tick help
Good luck

2001 s40 volvo diesel .. turbo oil leak ??

Could be the Turbo oil return pipe seal, its a cheap about $10 but you need to get to the pipe.
Its just a bit tricky to reach and you will need the gasket to go on the other end of the pipe when you take it off.
Its a well know fault check the Volvo Forums web site.
