V50 Engine 2.0D : - Warm/Hot starting problem

nozmeister · Jan 25th, 2008, 19:56

Hi,

I've a 2006 V50 2.0D SE which I'm fairly happy with however it seems to have developed an intermittant fault when starting the engine up which is not fully cold.

If I run the car for a 10 miles or so and then stop, wait an hour or so and then come back to start the car it sometimes takes three to five attempts to start the engine. The engine is always warmed up and it can sometimes happen on 60 mile trip. There are no problems when the car is cold.

Is this EGR valve related? As the fault is intermittant I'm not sure if the garage are going to find this and I don't want to waste my time going there to be told the usual "No fault found".

Any clues appreciated...

Thanks
Noz

It could be a tricky one to nail this especially if the garage can not reproduce the fault. Try and give the garage as much information as possible as to when the fault occurs and how oftern it does it, ask to speak to the Master Tech directly about the fault.

It may be the EGR valve but it could be many other things aswell.

Hopefully the onboard diagnostics will have stored a code which should make fault tracing easier.

Keep us updated how you go on after it has been looked at.

Ref my 57 plate V50 2.0 diesel.
I have got the exact same problem, starts perfect from cold, runs fine. Try restarting after say 10 or 15 minutes, and it just won't fire up. Have read various posts and everything seemed to be pointing to the Throttle body/housing which has a flap in it that can stick. Had that replaced today.....same problem occurred after about 15 minutes of driving.

Anyone any ideas?

Same problem on my 55 V50. Only does it after long drives (so if the engine is hot) and I stop off somewhere for 15-20 mins then jump back in and start her up, just doesn't fire! Probably should add that if i pump the gas peddle whilst turning it over it seems to kick it into life, only just recently found this out.

Gradually getting worse, as it seems to be struggling to start ona morning more recently. New started motor fitted end of last year so I know its not that.

Any help greatly appreciated.

I would certainly suspect the Throttle flap. Clean or replace. Do a search and hve a look for how to clean or replace.

I have the same problem with a Volvo, a diesel engine, the engine starts on cool and hot, and does not start on warm. I changed the filters and oils and pumped the diesel, but it did not solve the problem. Tomorrow I will visit the Volvo center.

over tightening of the throttle body can cause problems. there is a mod which involves filing a small amount off the butterfly valve to stop it sticking. a live data scan with vida can check the duty cycle of the egr valve . as they can stick open or closed. replacement can be done. access is awkward with some fixings difficult to see.
