Engine Clean

If I cleaned my TDI would I actually gain anything and what would I clean? Is it simple to do?

In what way are you on about?

As in cleaning the inlet manifold, EGR valve, intercooler etc?

Or simply cleaning the engine bay

EGR etc...

Less smoke, better MPG, better performance

Personally I'd ditch the EGR and fit a delete pipe from Allard

sorry for late reply....just got in from work....whats the price of that thing then?

So just cleaning the EGR or infact delelting it would cause better performance, more or better mpg?

or even cheaper this but it states requiring fitting large bore inlet manifold?

Why is everyone deleting the EGR valve, why did VW put it there in the first place? Just worries me as I have read bad things like their VW dub smoking more and turbo dying etc  Just be my luck for mine to go thats all

All it does it provide two operations

1-Allows to reduce the emissions by recirculating some of the exhaust gasses at idle. This is not needed in this country as diesels are not tested on emissions.

2-The car will somewhat splutter to a stop when you turn the key off. The EGR has a anti-splutter valve that closes a butterfly valve starving the engine of air. In some very very rare case the an engine can run off its own oil.

so all in all not much point in spending 50 pound or so......oh well ok

You could just take if off and give it a good clean and block up the vac pipe running into the top of the EGR.

just worried that i might ruin something or damage the egr valve and cost more money...car has done 112k and I have never cleaned it and owned it from 62500k.
