The EGR is visible behind the cam cover, access is better if the bulkhead extension (scuttle) is removed.

Tools required quarter inch drive socket set with torx bits is best.

Remove the large air pipe held by spring clip and pull off the two vacuum pipes, then there's 3 bolts attaching valve to inlet manifold and 2 bolts under valve attaching small exhaust tube, can be a bit fiddly depending how good you are :D

Thank you very much for your detailed advice.Going to give it a go. Hopefully it'll be ok.

 

thanks again

Got a bit waylaid. Going to attempt it this Sunday. Just to clarify, is this the valve?i seem to have a few more bolts.

Hold up no thats not it, thats the tandem pump (vacuum & fuel pump)

 

As you look at the engine immediately behind the oil filler , it's just out of view in the top picture.

The large air pipe is connected to it

 

here is a pic of mine, you will see the small vacuum pipe on top

Fidly to get off, but managed it( with allen keys and tork set). Very clogged up.Cleaned it.Could move the valve up, so assumed it was ok to replace.Did so but still black smoke coming from exhaust, but not so laboured in lower gears.Should i have bought a new valve? Or is smoke from debris still left in tubes?

cheers.

The EGR valve is held shut with a strong spring, and opens when vacuums applied according to operating conditions, the flap valve should be open all the time engine is running, only closes momentarily when switching off engine.

Sudden black smoke could be down to over fuelling or more likely restricted air supply/charge pressure deviatiion (underboost)

This could be turbo vanes sticking or maybe something more simple like a perished turbo actuator hose or one of the intercooler pipes split or perished, or damaged intercooler radiator

Have a close inspection of all those items.

Thanks for the info. Will have to get my mechanic to look. seems a bit too complicated for me (im strictly nuts and bolts not diagnosing) as i dont know where these parts are.

thanks again for your time.
