VAG Techies....Possible Consequences of topping up a PD engine with non PD oil
Is it anything to worry about - a mate of mine topped their 130PD engine up with 2 litres of 15/40 Standard Diesel oil.

Couldnt you drain the lot and refil with PD oil - then after a few hundred miles drain it again and refil?
Thus using the original fill as a flush so to speak?
Sorry, I dont even know what 'PD' oil is. Its just what I'd do if I stuck the wrong oil in something (admittedly less advanced as I only ever own old crap cars).

We have about twenty 07/08 plate passats at work....virtually ALL of them have used loads of oil and they regularly get the oil light coming on......all are under 12k miles too!
Whats the score with them?

We use Castrol LongLife III on all VW diesels there, and no real problem. Only see 1 customer each month with oil light on. Not more. Use VW oil spec 507.00 for all VW "modern" diesels engines and it should be fine. 
Otherwise use Golf Synt oil.

More seriously, its not just a problem with VW engines (and by VW I do mean engines are used in Skodas, Seats and Audis), but with all diesel engines are crap. Its just diesel...

We look after a taxi at work that has the 1.9pd engine and we just put normal 10/40 semi synth in it cause the owner is to tight to pay for pd oil and one of them has over 200k on it and only thing it has had engine wise is a new clutch at 120k.....
The same owner wants his handbrake on 1 click everytime we service the car then comes back saying its sticking on after a few miles and wants it looking at but still wants it on 1 click....lol

I know you can set the EGR adjustment down using VAGCOM as well cant you.

Thats VERY interesting actually......the persons car who had to top up the oil, has just had the turbo let go - the cars got an Allard EGR Removal pipe on there - according to the service history its the 3rd turbo thats gone - its only on 96k - the garage said it was because its been re-mapped to roughly 180bhp & couldnt take the pressure!!
Although I thought the EGR re-circulation only occured under part throttle not under wide open throttle - if so how can the turbo overspin as I doubt you would get full boost on part throttle?

Doesn't need full boost to overspeed. EGR will go in at full pedal, just not at very high rpm, so upto 4kish you'll do a lot of damage
I run engine dynos for a living mate - and alter all ECU variables daily, main timing, boost, throttle, MAF (EGR basically) etc
And how MAF/EGR effects the turbo speed (instrumented so you can see the actual speed i,e 240,000rpm
) is very suprising at first

Also, there will be certain parts in the map, that EGR is the ONLY thing stopping the turbo overspeeding (as it reduces turbo speed). I've removed too much EGR many times, and then the engine shuts down because it knows the turbo has oversped, obviously a car does not do this, as it does not have a turbo speed pick up
