Cost prices to everyone but Preeny.

So why are you going to give Preeny a freebie - is he your current BFF or something ?

[Greg Roles]

He is...he just doesn't know it yet.

I meant Preeny pays a premium!

All that gunk is really quite scary. I thought VW were good engineers. Why didn't they engineer this gunk out of the system to prolong engine life. Maybe they are thinking along the lines of the chinese and design something to just last past the warranty and then die like my kettle. I reckon theres an art form to predicting when something is going to die.

I am really tempted to perfom inlet surgery on my TDI as well but the car being under warranty is always on the back of my mind. Maybe next christmas santa could give me a mann oil/air separator and a day of patience.

Given the obvious need, and the number of requests, plus the plumbing hassle, I'm going to investigate putting together a fitment kit for the Provent for the oiler crew. I'd recommend anyone who is handy under the bonnet get onto this asap, but give me a few days to see if I can set up a trade account with Mann and Hummel specifically under one of my businesses.

I'd say a well thought out kit an instructions could be quite a seller here and OS... I'll wait until you know more before I go down this path.

Man that's dirty!

I asked my dealer to check it and he said it's fine. I am thinking he lied to me now. I will get Derek to look at it next week.

But aren't they designed to never be squeaky clean? That the EGR is a trade off of soot/gas and it keeps the EGT down?

It's all to do with emissons. I'm sure the actual engine design team didn't vote yes to the EGR levels, but had no choice to pass Euro V and VI. Decide for yourself, but the best avenue is a Provent and the odd spray flush offered by VW, as hobbling the EGR will indeed raise EGT's and CO outputs. I've been making sure my inlet is as cool as possible, and along with water meth my CO should be as low or lower than stock when I remove my EGR completely. Those with DPF's need to be extra careful, as that gunk when spray cleaned will most likely end up in the DPF as non regenable ash. And that is direct from the VW tech bulletin I have talking about oil burning to ash, and that eventually clogs the DPF permanently.

Haha i was wondering why i woke up sore on the weekend and couldn't remember the night before.. You could have just bought my a drink instead of slipping something in it you know..


Good info here. Me likey.

Seeing all that accumulated soot and matter through the intake has answered a lot of questions I had about my last car and the steady decline in fuel economy and the assosciated decrease in performance. I can only imagine how my Fiat Punto Sport 1.9 JTD would have been faring when I sold it with 80,000kms on the clock......

Thanks again for the edumacation this thread is providing!

good work mate.

that looks a lot like the level of buildup we found on mollins 1z tdi before we cleaned and put it in the mk1... although a bit drier (less oil). i would say the pro-vent has probably helped quite a lot.

that throttle body assembly is a bit sad - be a good thing to be rid of that. how long before your warranty runs out?

Quick question - is this happening with all TDI engines, both PD and CR versions??
I have a brand new Skoda RS with the VW TDI 125kw CR engine fitted, only done a little under 4K in it so far - should I be checking the inlet for oil contamination?? I guess depending on what i find I should be looking at a Pro-vent to slow the problem down. But going off your pics cogdoc, it's doesn't completely fix the problem, just masks it for a bit longer and make it a bit more manageable...........
What a pain in the arse!
