My check engine light just came on. The test says that I need an EGR Valve. Are these hard to replace? and How urgent is it that I replace it.

Thanks

you most likely dont need an egr valve rarely go bad, that engine is very common to
have clogged egr tube the code is probley for egr flow malfunction this is really for a mechanic to do.

 

diaphram. I had a problem with my wife' car EGR, bought some carb cleaner sprayed it until the diaphram moved freely in and out again and reinstalled, had the dealer reset the check engine lite and it works fine now for 3 months. Should be on side of the engine near the exhaust manifold.

 

easy to replace,but check the vaccum hose and the exhaust system first.

 

es, good advice, then the whole system, is "new"
