From: Fred on 19 Mar 2010 08:47 Hi, Following on from my recent thread about p0400 and 401 diagnostic codes. What's the best way to decoke the egr bits and pieces? The pipe does have a sooty interior but it is only a thin layer; its not narrowing the bore of the pipe. The garage advised injector cleaner in the diesel but I read here to use ATF instead. Any particular type of ATF, I thought I saw two different types in the shop? Or is there something better? Using google I found something about carburetor cleaner but I'm too young to have driven a car with a carb, so I know nothing about what carb cleaner is or what it is good for ;) TIA

You will also see the results almost instantly. I'm not sure how effective the injector cleaner might be, but ATF is pretty much the same stuff except the cleaner has added ingredients (paraffin?). That is intended to be put in the fuel tank. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk

Thanks. I have been wondering about this. Why is carb cleaner good for removing soot from an egr pipe? After all, the fuel mixing in a carburettor is unburnt so there should be no need to remove carbon should there? |
