Hi, new to this and some help would be received very gratefully.

Last night filled up 1/4 tank of diesel, drove about 500 meters, parked for about 5 minutes, then would not re start and the oil pressure warning light eventually came on. abandoned the car for the night. went back to it with a tow truck ready and the car started. wtf. drove 3 miles to my house where I attempted a 3 point turn and the car has now stopped again.  

 

recently, there was a problem with the security cut out switch when locking and unlocking the car. left it for 5 minutes and it started.

 

Have I a simple easy fix problem or a major oil pressure problem and or electrical problem.

 

Hope some one can advise

 

Thank you

Hi, welcome to the forum.

 

I think the oil light is a red herring. The oil pressure warning light will come on through repeated cranking of the engine without starting. This is normal and not in itself indicative of a fault. I had wondered if you'd filled up with a contaminated batch of diesel, although you mentioned the car started fine the next day?

 

I'm not sure what you mean by the security cut out switch? Has this non-starting happened before?

Hi, 

 

Thanks for the answer. I got 3 miles to my house from where the car broke down and then tried 3 point turning it and it then seemed to stall and then would'nt start again.

 

A number of weeks ago i had a starting problem and I cannot remember why I knew it was that, but I called a friend and he said make sure I take the newer spare key. It definitely was'nt anything like this though thats why I thought that maybe I had a deeper problem with the electrics?

as for the fill up, i (think) that i instinctively go for the black minging filler. I had 20 km's showing on the tank and have gone well past zero in the past and since that, the car has had a full service. maybe tomorrow it will start up again and I can get to the garage? I would rather not though as I am in France at the moment and a recent turbo failure was actually a manufacturing default when they, (the skoda dealer wanted to charge nearly 2, 000€

When the car was serviced did they change the fuel filter? I'm wondering if perhaps its not quite sealed properly and letting air in. Can you see any signs of leakage from around the diesel filter housing lid or the pipes connecting to it? Fuel system air leaks on diesels can cause weird intermittent non-starting/cutting out faults like this.

 

It's possibly an electrical fault, but really to detect for example something like a failing crank or camshaft sensor you would need someone with VCDS software to scan it.

 

Immobiliser faults on these are usually characterised by the engine starting ok but cutting out almost immediately, within a second or so, and a 'key' warning light coming up on the dash. That doesn't sound like what you have here so I don't think it's related to the immobiliser.

yes, the filter was changed a few thousand miles ago at the last service. I'll have a look for leaks, but where should I be looking? currently the car is parked on wet grass. i make a habit when, say at a super market the parking space when i get back to the car and pull out a bit. not noticed any leaks that way. i do think its a sensor problem of some kind. where would i find that?

 

your spot on with the immobiliser. thats exactly how it was. just thought it could be related as electrical.

 

thank you FREEDOM

anybody with a possible solution please. don't really want to french expensive to say the least garage??????????????????

 

anybody?

As you look at the engine bay with the bonnet open the diesel filter is at the front left, its a cylindrical metal canister with four slim rubber pipes connected to the top. I would have a look round the top and pipe connections for any sign of diesel weeping from them. It doesn't need to be enough to make a puddle under the car before an fuel/air leak can cause starting or running problems.

 

Another thing to check is if the electric fuel pump in the tank is working. When you turn the ignition key to the warning light position you should hear a humming noise lasting for about 1 second coming from under the back seat, which is the sound of the pump priming the fuel system. If there's no sound it would suggest the pump isn't working.

 

To check for faulty sensors you really need diagnostic equipment like VCDS, or at least something that can scan for fault codes.

just started the car and it runs again, (after 24 hours of first trying again), sounds as though the idle is low and about to stall. looked on another blogg and maybe like you said nick74, or anyone, "crank or camshaft sensor" what do you think?

 

dunno if it makes a difference but my son in the back noticed that the esp to control the traction control came on or off. oh and another thing that may or may not make a difference, last service, the service warning message was never reset.

Perhaps, but equally that could be caused by fuel starvation. You really need to get it scanned I think or you'll be replacing parts by trial & error which could end up costing a lot more in the long run.

yeah, 

 

bite the bullet and get in diagnosed

 

thank you for the advice and when I know what it is, i'll write back.

One little bit of info - your car has two lift pumps in the fuel tank as the tank is saddle shaped because of the prop shaft to the rear diff.

Interesting, I didn't know that.
