Engine management light flashing - losing power

Hi, I have been driving my 2005 1.6 megane privilege for about 8 months now without any problems. I did have a couple of issues where the car would not start first time in the morning, but after a couple of attempts it was ok, and this was intermittent.

Today I was driving along a started to lose power and the engine management light started flashing. Can anyone give me some advice on what this might be?

I've read around and found it could be the engine coils, are these expensive to replace?

I'm going to take it to the garage tomorrow but hope someone may be able to give me a heads up as to the problem!?

Many thanks in advance!
Dan

The two most common causes of poor running on Renault engines seems to be either duff coils or TDC sensors so it may well be worth getting those checked out first.

Thanks for the response, how much would I be looking at to replace either of these from somewhere like nationwide autocenters?

Depending on the quality each coil could start at around 15 plus each plus labour. If you find out its a coil problem try to identify which ones are duff and replace only them. Generally it only takes around 10 minutes or so for each coil and if you have the tools you could attempt it yourself. But find out the exact problem first

Absolutely no chance of me doing it myself!! I'd end up doing more damage!!!

I've been told its best to change them all, it this true, if so i'd be looking at 150ish??

Do these affect fuel consumption as well?
