Most cars have them by 2000

isnt the Wynns step a bit of a mine field?

Im not an expert at all but I've been reading all sorts and the general consensus has been, if you have a new car or its had plenty and regular oil changes then its fine, but if its a bit long in the tooth with unknown oil changes then doing it may give you more hassle as it breaks up all the old crap, which may either lead to leaks or more likely block things up as it comes off and floats about. I read somewhere that if your going to do it on poorly looked after engines or long oil change intervals, then the first time you'll need to clean it change it, run it and repeat it 2 or 3 times to help reduce the chance of crap getting in to places you don't want it, suggestion was to use cheap oil first for a couple of hundred miles then on the final go put in the good stuff. Using it after should be fine so they say...

We have to be clear that we are talking about fuel or oil additives, you sound like you are talking about oil additives Lenny is talking about fuel additives (obviously 2 different things)

Fuel additives such as Winnes cannot clean the EGR valve, or inlet manifold, they can only clean the fuel lines and injectors, combustion chamber etc, the fuel goes nowhere near the EGR valve or inlet manifold on a direct-injection diesel, to clean the inlet manifold (or EGR valve) you need to take it off and clean it properly

So does that make using the oil tank cleaner a nono then?

Aye, sorry I was meaning the oil in that post, the fuel additives are amazing though, I used some AR6400 to 3/4 of a tank, unbelievable difference to the noise it makes and a noticeable difference with mpg and response. I really cant begin to describe how much of a difference this makes to the sound of the engine, if its sounding like a tractor the injector cleaner can sort it.

Mine wasnt easy egr was at the back i had to get the 1.8 most awkward one but il upgrade the air filter wen i can just bought a halfords own one for now

My air pipe wasnt even attatched to the box so the extra air pressure that has been escaping from the engine has been stopped

My air pipe wasnt even attached to the box so the extra air pressure that has been escaping from the engine myt of been causing the low power ive been having now ive cleaned the air box clamped the pipe on and a new filter it ran better and blanking the EGR aswell it feels loads better cant wait to give a good clean through and service it should run alot smoother

Can anyone tell me where the EGR valve is on the 2.0 TDCi on a Mk 2.5 at all? At the front I think I have read?

Not sure it helps but I have. Mk1 and I just followed the pipe from the inter cooler and I found it mine was at the back of the engine

I've got the 1.8 Tdci (Endura) engine and I'm having difficulty finding where the blank slips into. There's 2 places that it could go

Cool beans. Thanks. I've only got the one plate so will go for the exhaust side of the valve. I guess that is the idea and/ or the only place the plate will fit.
