Hi i bought a W reg 2000 Fabia 1.4 16v. The light is on the the previous owner says its been on so long he ignores it.

My collegues have been sorting it clearing codes etc and have now fitted a new lambda sensor and a egr valve, it went of but now has come back on.

thoughts please

which light ?

..is the EPC (electronic power control) light on the dash ?

If so, mine went the other day, apparently all it tells you is that there's something wrong with something, and it could be anything. Mine was because my brake lights were buggered, just a thought as it's well worth checking your lights to see if it's them ..ya never know

He says which light it is, the engine management warning light.

Unfortunately this is a common problem on Skodas, the light can come on for almost no reason. Lambda probe/sensor is a common one as is the EGR valve.

With the EGR valve, replacing the valve can sometimes displace dirt/gunk which can then cause problems with the sensor. This will cause the engine management system to again report a fault with the valve and to light the warning light.

Cleaning the EGR valve and the chamber may help or it may be that you are unlucky and the light continues to come on.

I am suffering this very problem at the moment. EGR valve was replaced last September, things were fine up until January this year when the light came on again, EGR valve again. The garage checked the valve which was fine, and cleaned everything again, but a day or so later the light came on again. Now it is on nearly all the time. I get the fault codes checked occasionally and it is always the same thing, reporting a faulty EGR valve. There is nothing wrong with the valve and the car drives fine without problems, so now I just ignore the bloody thing.

Skoda were useless, wanting to fit a new engine management system at huge cost. My local garage advise me to ignore it.

This is probably a dumb question ('cos I don't really understand what an EGR valve is) but would the sensor come on if the engine was burning oil?

The reason I ask is that I've had a problem with a warning light for over 12 months and was told it was a valve in the exhaust. the gagrage has now done a compression test and says I need new piston rings - 1.4 16 v Fabia which apparently has known problems with piston rings.

Best thing to do when the warning light comes on is get the logged fault codes read off by a dealer or someone local with VAG-COM. That should tell you what the car thinks is wrong....

mine has been on for two months now and garage can't find nothing wrong, I just ignore it, you could always take the bulb out

On my last car I used to ignore my warning light and occasionaly it even turned its self off for a while.

My g/f's vectra has had its warning light ever since I met her and it has no problems.

But if the warning lights always on, how will you know when there is a real problem? :P

I got mine cleared on my old car and it still came back on so unless I wanted to take in every week I just carried on with it on.

my focus has it's warning light on and it is the crank according to my friendly mechanic, hence one of the reasons why I'm changing in the next two weeks, I would have been changing anyhow to cut costs of runnign two cars and somethig newer, but I don't fancy paying out for new parts to my 6 year old focus.

You fancy buying a Fabia 1.4

If its the 16V could it be the problem with oil by-passing the piston rings and bunging up something (i forget what it is , some valve I think) Does it use much oil?

Loads on the 1.4 16v on here allready.

Piston ring issues mean the engine breathes heavy. Crankcase pressure gets to high and oil is forced into the intake (check the air filter and throttle body for oil). The oil in the intake bungs up the EGR, manifold pressure sensor and the throttle body to name a few parts. When changing and EGR valve (if you must) it is essential the metal pipe that goes back to the throttle body is checked for carbon. if this is still blocked hen the same fault will re occur.
