Fuel serge causes Limp mode/ Glow plug Warning Light ON


Recommended Posts

I bought my 2.Ltre D 2004 model 3 weeks ago, I new it had a fuel problem with a reduced price agreed as the repairs could amount to a fair bit ! only 62,000 miles. You can see my earlier post

about EGR Valve cleaning.A Long story short, i'm now on my third injector valve removal and cleaning. The 1st was change with recon Valve making no difference so cleaned original and put it back in. 2nd valve was replaced with new (recon) again and wow what a difference! The car started with a puff of smoke but that was it, Idle was stable and it sounded like a tighter engine ! completally different sound than before, I drove onto dual carriageway and let rip it feels like a new Car.

I recommend you clean the valves before spending lots money.

You should be very Careful doing this job, 1 injector at a time making sure no crud or dirt enter inlet

holes on top of valve, plenty of rags for cleaning, Remove excess oils first with rag, I used Holts engine cleaner spray, important note:

Do not spray into top half of Injector. Hold Injector upright and spray up into nozzles at bottom of injector at close range, important not to push crud/dirt in holes with rag ,let the spray clean the holes

until you see jet holes and carefully wipe in down strokes to remove heavy greased areas, when refittng check is washer at bottom of the jet or still in the seat of Block hole, if washer is loose

and out of block, A little tip is to use a metal coat hanger straightened cut about 16"s in length and put into injector hole and slide washer into injector hole, to prevent washer being dropped into rocker bay! These injectors are easy to remove and refit using the Diesel injector socket with window, 21mm on eBay about £10.00. any questions I will try to help you.
