Car won't start, oil indicator light flashing

[Jindera]

After fixing a dud window regulator and checking fluids etc, went to start car and just didn't want to start. Checked fuel pump fuse - OK. Oil indicator light flashing but there is enough oil. Any ideas?

Thanks

oil light will flash after cranking for a while as its not building up pressure........check all the fuses not just the ones labled with stuff like "fuel pump" as some fuses are linked with stuff weird like cig lighter etc, so check all fuses first and then back step and recheck your window reg work........vwtech........

Thanks- fuses and work checked - all in order. Reading other forums, dud relays (no 40 - ECU, in particular) appears to cause similar problems - what do you think?
Something else which I've just noticed, is on withdrawing the dipstick there was a small piece (about pinhead + size) of what appears to be hard tan/ brown plasticky materiel stuck to it. This happened twice now and I was wondering if there is an oil pressure sensor or something similar that may have failed/ disintegrated internally?

Grateful for your ideas.

The light flashes until the engine starts that is normal. If it keeps flashing when the car is running, there is a problem.

I reckon you knocked a wire off the coil or starter in your tinkering and thats why it wont start.

Does it crank over??? If yes, check the coil, if no, ignition switch.

Thanks - no wires knocked off because I wasn't working in the engine bay. I can't hear the fuel pump working (fuse is OK) so perhaps its the relay?
