Afternoon all
First post and a long old story.
Had some really bad white smoke issues from my 56 plate is220 so took it in to Lexus Edgware for a full check up.
They came back with a quote for £5k of work including EGR replacement, new DPF and new fifth injector. It was safe to say on a car this old I declined there kind offer and took it to a good friend of mine who could only find a fault for the egr which when replaced left the car with much more power and better pick up all round.
I still however have huge plumes of white smoke at times in many different conditions which I am guessing is down to the Fifth injector passing to much fuel through as it smells of diesel so the presumption is that it is unburned fuel. Before I'm asked I have no other signs of HG issues and it really does stink of diesel.
My question is has anyone ever replaced the Fifth injector on here and how big of a job is it as I am aware of it's awkward location? Will it need to be programmed to the ECU and can I get away with picking up a second hand newer one as Lexus quoted around £1200 for it to be brought and fitted and on a car this old its not worth that cost to me.
I actually really love my car as it's a motorway muncher for me I just want to lose the annoyance I have of continuously stressing an feeling embarrassed at the clouds of white smoke behind me!
