Citroen C5 - egr for citroen c5 2002 - monty05

hi i have a citroen c5 2002 and it goes into limp mode when going up a hill, i called the aa and they undid one of the pipes that go to the egr and sprayed some sort of oil into it to try and free the valve inside, was this the proper thing to do or should i have it changed because it still happens please help.

You really need to get the fault codes read as the fault maybe something else. If it is the EGR you can get some cleaner which you spray into the air intake which can be effective in disolving carbon. You could spend a lot of time and money trying things but you need someone with a Lexia code reader to find the real problem.

If you go onto the 'French Car Forum' there is a list of members with a Lexia, you may find one near you.

If you do have an EGR problem then it won't be limited to the valve itself. If the valve is coked with carbon then so will be the rest of the air intake downstream of it. The whole lot will require cleaning. The EGR valve opens and closes, and so long as it does there can't be much more wrong with it.
