is there a way of turning off the EML light with out using a VAG com as i am getting the errors below and will be changing the glow plugs soon but want to turn the light off in the mean time..

No, if the glow plugs continue to log faults the EML will continue to illuminate.

 

The only way to clear the light is to fix the fault.

There is little point in just turning the light off without fixing the problem, as it will back on in a few miles.

just waiting for my mate to come back from being off shore to fit them, i just it just that and not the ERG thing.

Fixing the glow plugs first makes sense as this is potentially the easiest and most cost effective fix.

 

If it is the EGR then this is either a time consuming and dirty job or a relatively expensive one.

The eml won't be on because of the glow plugs it will be because of the EGR, I have seen glow plug errors before and they tend not to trigger an eml.

+1

Also when you fix the EGR fault the warning light will turn off on its own anyway after a certain number of cold starts with the fault no longer present.

Have you got my car? I had them two exact faults. Glow plug now replaced (do a full set they are not expensive) I am trying to find a guide to clean EGR and remove inlet manifold as I believe that is also likely to be grotty.

ok fitted Bosch glow plugs still the same error, so now going to CAP the EGR and am i able to remap this so it does show up as an error using my VAG COM or do i need to take it somewhere to have it remapped?

I cleaned mine yesterday, wasn't too bad took about 3 hours. The egr was very dirty, the exhaust side valve seemed to be the problem as it was caked there and all around the stem meaning the vacuum couldn't operate. No eml back as of yet but have a 100 mile drive today to see if it comes back.

is it worth blanking it off or cleaning it, or even buying a new one?

Check the vacuum by putting a hose on it and suck...wish I had! If you can suck freely its dead, if not its worth trying a clean. Blanking it off requires a delete kit and the EGR mapping out, unless you wanted a remap could be expensive. I just bought a new wahler one from ebay £63 and the fault is gone , hopefully for good. Took around 60 minutes to swap. I read all I could digest on the subject and weighed up the pros and cons of replacement vs delete. For me I do a lot of motorway trips, roughly 60% of my driving is done on fast A roads and motorways so hopefully the new egr should get the blow through it needs. My car is a high mileage one so I'd be cautious about remapping it so any work would be just to delete the egr. I read about increased temperatures and increased wear on turbos due to warmer oil. And in the end it came down to a new egr being the cheaper option for me.

why are thing never that simple. i buy a blanking plate fro £7 but then need it remapping to delete the EGR cost about £100.  or i now buy a cheap EGR for about £70 which if im lucky might last a year and back to square one.  thats cars for you lol cheers for all your help on this.

I'd expect an egr to last more than a year.
