Help with this madness please

[mm3260]

i have an octavia 54 plate. Recently the engine management light came on and the glow plug indicator came on and have stayed on ever since. Code said it was Crank shaft sensor on one reader and engine speed sensor on another reader.

It is really difficult to start when its hot or cold. Normally cuts out after driving a few miles then difficult to start again.

Mechanic (not skoda) tested glow plugs and found that 2 were u/s and changed them. he ordered a crank sensor which turned out to be the wrong one.

Skoda have said i need exact part (choice of 2) 036 906 433e or 036 906 433b. All brake lights are working. Mechanic is p**d of and has not given me the existing part number coz he put it all back together.

Help pls

Hi Mike, not sure if this is the same problem that I had with my 88000m 05 reg but the symptoms are exactly the same. Crankshaft sensor didnt fix it nor did a engine management flash update. Turned out to be a wire rubbing and then earthing. As you look into engine bay on right hand side, low down and below the air trunking there are a few wires going across the engine. One of these had rubbed the insulation away. Its difficult to see with the air trunking in place. It took the garage 6 hours to find and fix. When I went to collect my car the mechanic showed me a taxi that had the start of the same problem but the wires hadnt yet gone right through the insulation, he said it looks like it may become a common complaint.

thx for that, ive now got the correct sensor but the mechanic damaged the connector into which it plugs. I am hoping that he can find a replacement coz Skoda were no help.

If all else fails i will get him to look at the wiring.

Cheers
