Has anyone found an additive th at actually cleans the EGR cooler without removing it from the engine..........or major dismantling ...........2.0 diesel 

Merry Christmas!

 

Having removed and cleaned one recently I really doubt it, considering what any additive would need to travel through to just reach it. Decent fuel and additives (aswell as making sure everything else managing fuel:air ratio is on point) could help prevent it I imagine but I'd only go that far.

I've been quoted a rediculous amount of money to replace it..........

Ridiculous on what basis? Are you capable of DIY'ing a replacement?

 

If it has not already failed you could avoid the expense by investing now in an emulator/simulator (was £99) which will stop the corrosive EGR gases from passing through the cooler on their way to clagging up the intake tract.

 

It can also be fitted after failure (leakage of coolant) but is a little more involved as pipes have to be blanked off.

 

Mine is still doing its job of fooling the ECU faultlessly after 50k miles.
