I know its not recommended on the 1.8t, what about TDI?
:huh:

What sort of engine flush, how do you mean? :undecided:

You just take the sump plug out and run the hose through the oil filler cap until the water runs clear whilst leaving the car ticking over :grin:
-
personally id never do it unless its been done since new. but thats just my opinion
-
LOL doubt that would end well :laugh:

People use this religiously in some places. Won't do any damage if you do use it... :smiley:

"Engine flush" is only useful if the oil has been left in too long and sludge has built up. If this has been left too long the flushing agent can cause damage as a load of carbon gets liberated and can cause seals to fail and the filter to get blocked.
All the reasons for not doing it on a 1.8 T apply to a diesel only more so. Boost is higher and so is compression.
If you have a basket case that has not seen a change for 40k miles - and as a last drastic step - by all means give it a go.
If it was mine -not at all. Ever.
Doubly so for a turbo engine - turbo bearings probably have the highest lubrication requirements of all the bearings in the engine. You are proposing to add something to the oil the designers never planned for and can only reduce the lubricating properties of your oil.
Give it an oil and filter change every 3k miles for the next 12 months. Fully synthetic has the best cleaning/suspension agents and out of those one approved for extended drain will have the best. That will do all the flushing you need gently and in a controlled manner.
Once that is done - stick to the service schedule (or even better more frequently) and use a good quality oil and you will never need a flush. The oil and filter will do the job they are designed for.
That is to keep the crud from your engine in suspension and filtered out until oil change time when it gets removed from the engine.

Interesting to know :wink:
I thought it was just like another form of Redex and the such... :undecided:
But a lot of diesels, I say a lot I only know of the PD engines, require a specific type of oil other wise the cams turn to chocolate. (Another disscusion for sure). So I'd guess a more frequent oil change would be required!

Good point Scarr - should have said to only use oils approved for your motor. If that allows you a choice of extended drain then use that.

Gotcha. I learnt something today :afro:

Think its been done quite often. Worth running some cheaper oil to clean it out?

So why do you think it is dirty and need flushing?
If you really want to flush it then use an oil approved for your engine with a new filter. Run it until the oil on the dipstick goes black - probably about 3k miles. Drop it out, replace with an approved oil and filter.
If you are really worried about it - repeat the above and change it when it goes black. Forever. That is the best protection a man (well, his engine) can get - but it is overkill.
Could do with Oilman's opinion here but IMO - a turbo engine would be better protected at the end of its service interval with fully synth oil than running with cheap (non turbo) oil on day one.
So no. I wouldn't put cheap oil in it if it was mine...
