I'm getting an EGR light, 1.4 16v BBZ ;  looking at prices on ebay I see that to clean it might take £12 of cleaner plus time and a replacement about £30 and far  less time.

Replacements are priced  from under £30 to £130, it's a solenoid, how can one cost for times another ?

The car has done 177,000 miles I don't think it will do enough more to justify the 'buy cheap buy twice' dogma.

 

It looks a straight forward swap out, but is there anything to catch me out?

Try unplugging it completely, clear the codes and see if it runs better.

I forgot to disconnect but did a 100 mile round trip to judge how the car was performing, it was fine, same as usual but the strange thing was that the fuel consumption was better.

I did another trip about the same yesterday and, once again, far better mileage.

The only other change was to change a front wheel bearing, I can't see that that would cause a 7% drop in mpg.

 

Perhaps I should just shrug and leave the light on.

 

I'll try the disconnect later to see what happens.
