Engine Management Light came on today

Was an absolutely lovely day today (hottest since getting the car) so took the car out for a wee run as I needed to get more fuel anyway.

 

Got onto local B-Road (private land, of course) and ran it through the revs in 3rd. Slowing down after this, the engine management light came on.

 

I trundled for the next 2 miles at 40 and stopped up at a big car park, left the car a couple of minutes then switched it off.

 

Upon switching it back on, the light was gone and there has been no trouble since (driven about 100+ miles more).

 

Oil pressure and oil temp were reading fine off my gauges, there was no loss in power and it was boosting same as ever. Had absolutely nothing since either.

 

Any ideas as to what this could be caused by?

 

One mate I spoke to said it could be brake fluid level.

 

Thanks in advance :)

Yes, brake fluid level is a common cause, as is a "speed sensor" error. But rather than guessing, it's best to get the error codes from the ECU. The engine management light tells you the ECU has just stored an error code, so get it to tell you what the code is. Simples! :) It's dead easy to get the codes, just search on here for how to do it.
