[cornishprincess]

please excuse the essay but the more info i give the more chance there is of someone being able to help.......we have an 08 skoda octavia elegance 1.9 tdi estate, we were going round a very busy roundabout and it died, would not start, we were pushed off the roundabout and called the breakdown, my husband is an engineer so half an hour later whilst waiting he tried to start it and behold it did..turned off the engine after a few minutes and tried again, no start, breakdown came, he connected the fault thingy and it said sensor, as he was a mechanic we believed him when he said it was the crankshaft sensor but he said to make sure drive it down the road and call me when it dies...we did , it did and we called...towed home...took it to our local garage which is a vw specialist , he changed the sensor checked on the fault thingy, no faults and dropped it off..husband went out and it wouldnt start and the temp light had come on, it hadnt been on before at any time,  garage picked it up, checked the fault thingy, no faults...sent the ecu away for checking, came back good, changed the glow plugs and the coolant temp. sensor, garage believed it was fixed, took it for a drive and it died...the problem is still there and now the garage has decided they dont know whats wrong so cant fix it...still no fault codes showing...temp light still on...car still dies when it gets hot....does anyone have any ideas that havent been tried, we have been without this car for weeks now, i have trawled the net for answers without success, someone please help...xx

Choked fuel filter? Sorry clutching at straws but if it dies then as you said a while later it starts then dies again, maybe restricted fuel flow?

 

or, coolant blockage or restricted flow and overheating maybe?

 

Interesting one. Hope you get it fixed. Has it been connected to proper VCDS? Maybe the "fault thingy" was just a generic obd2 reader.

[cornishprincess]

the fault reader at first was the breakdown man obd reader but the garage did a proper one, both faults were the same and when the garage checked the history of faults that was the only one, just cant understand it, we all know there is a fault somewhere but no-one not even the vw garage can find it, and until the crankshaft sensor was changed we didnt have the temp light come on...so frustrating..thank you for your suggestions..x

[pikpilot]

Which temperature light is still on? Is it the low coolant light?

[SuperbTWM]

Don't let the garage throw any more parts at it until you get somebody who knows what they are doing and can diagnose it properly.

 

As above, you say you have a temp light on, have you actually checked the coolant?

[xman]

Hey, check you've not run out of fuel? If you have allowed air into the fuel filter it takes a lot of cranking to restart (after putting some diesel in).

 

When was fuel filter last changed? Might be full of water if very old.

 

Other thing to check if you recently refueled did you misfuel with petrol?

 

If this was an 1.9 tdi Alhambra the answer was almost always relay 27. Dry joints in the relay, intermittent starting/dying. Could be similar.

hi guys...wow..ok...the garage told us today the car is ready to be picked up, theres nothing more they can do....after all they have done and checked we were told 'NO CHARGE'...all they want is that should we ever find the problem we let them know, what is was and how it was fixed, this was a family owned vw garage that has been running for many years....the coolant has been checked as has oil, water, fuel, we did not run out of fuel, i am disabled so believe me when i say we never , ever run out of fuel, or put the wrong fuel in, having spoken to my husband in depth on the subject of the skoda, he informed me that the temp light is not on when the car starts but comes on when the thing dies, oh and the sensor in the coolant has also been cleaned and checked......please keep the suggestions coming, they are really appreciated...xx

If its a mechanical fault a code reader is no good,if there's no fault codes then its back to basics like fuel,first and cheapest thing i would do is change the fuel filter as already suggested,could be fuel pump fault but i think that might throw up a code,cant understand a garage giving up on it that quickly.

[Busamad]

What is your engine code?

What fault code numbers led them to change the parts mentioned?  Does not sound like a good garage.

Maybe relay 109 at fault. Do all the normal dash lights come on then go off when starting?

But would always look at fuel delivery as the starting point if no codes.
