My EGRs have been blanked for at least the last 40000 miles. During the blanking procedure I cleaned the sensor and manifold section that it fits into , and this is what the sensor looks like today....

No crud whatsoever, just a smearing of oil. Before the EGRs were done it was caked in carbon/oil crud, and i needed a small drill bit to clear out the hole (at about 80000 miles).

I certainly am on the original MAP sensor, and have Installed a BAS Blanking Kit.

Not too bad IMHO, still cleaned it as it was out.

Mine looked like lad's sensor so wiped it with a shop towel and used EGR cleaning spray to clear the hole. I BAS blanked my EGRs last year and the intake stub-pipes were in a horrible state. Thinking back on it I really should have taken everything apart and cleaned all the black gunk out.

As a slight worry she was a bit reluctant to start afterward but all seems ok now.

Mine was also just like lad's, sensing hole completely clogged over with oily black crud. Hope this is the reason for the <20 mpg I've been getting lately Big Cry . Thanks for the pointer Derek. Thumbs Up 55 Plate, EGR's not blanked, 38K miles.

Remove oil filler cap, pull the engine cover off, replace oil filler cap, and you'll see where it is, just in front of the oil filter housing. Its fixed with a torx screw.

Not been touched since new as far as I know Whistle

Just took mine out, quite dirty, cleaned and refitted.

Maybe me, but seemed to start slightly easier/settled to smooth idle faster from cold.

On the road, seems slightly more responsive, have to see how the MPG fairs.

Thanks for the pointer Derek Thumbs Up

This also makes interesting reading Thumbs Up
