Differences between VAG cars
Discussion
Chaps
My knowledge of all things VAG has been called into question, and I need help settling the office argument.
A new, young sales bod has started, and there was a jovial discussion in the office about the fact he "is a cock 'cos he drives an audi". I jokingly said he and one of the other Audi drivers should have bought the Skoda, after myself being impressed with a couple of them i owned in the past.
So, it turns out new boy is straight from a sales role at an Audi showroom, and starts telling me there are differences between the A3 and Octavia. He agreed with me they are based on the same floorplan, and we agreed that the main differences between the two were the quality of the interiors.
Anyway, he then mumbled something that "There are differences in the engines. The CR 170 engine in the Audi has different internals to the skoda. Especially with the MPi and stuff"
Now, I thought the MPi engines were just a moniker for the (older) petrol engines from the VAG group? However, I settled to agree to disagree with the boy as I'm never complacent enough to think I know everything.
So, over to the experts here, are there any differences between the two? Do I need correcting and have I got to go back with my tail between the legs and tell him he was right, in front of the whole team?

Same engines, just different states of tune...sometimes...internals no different...however....
There are numerous different 2.0 "TDI" engines though and at certain points different VAG group cars have been fitted with different engines, but on paper they are 2.0 diesel turbos...this may be what your young friend is referring to.
For example 2006 was a good year for this... i am an ex Bio dieseler so know a little more than most given that some engines will take it and some wont. Skoda Octavia 2.0TDIs were still being fitted with the 140BHP engine that was A PDI and so will take bio (a development of the 130PDI engine from the earlier cars), but some audi's of the time and seats got the CR common rail unit that will not eat bio, however you can (if you look hard enough and check engine numbers) find some 05 A6's with the Bio friendly engine.
So different internals..same model year....

I think the confusion comes from what "same engine" is. If it says 2.0 TDI on the boot that doesn't refer to a particular engine, just the fact that it's a 2.0L diesel with direct injection and turbo (it could be CR or not for instance. or have different maps/power), the engine code will reveal more details. But a particular 2.0 CR TDI engine as fitted to different VAG brands will be 100% identical. It'd defeat the object of the ecomomies of scale if they started using different internals.
Main difference is between the longitudinal engined cars (anything Audi A4 upwards, SEAT Exeo and VW Phaeton) against the transverse engine cars (Golf/ Passat, A3/ TT, Octavia, Leon etc). Nothing is generally shared between those two categories due to the large technical difference, but within them a lot is shared.
VAG are moving towards universal one size fits all platforms with MLB for Longtidunal cars and MQB (also NSF) for Transverse models.
Oh and the stuff about MPI is rubbish, that's just what the old 3/4-cyl N/A petrols are refered to

As pointed out above different brands changed to the new engines at different times. My 59 plate Octavia is the first of the Common Rail engines. Audi and VW had them a couple of years earlier while Skoda were still on the PD, so you could get an Audi and Skoda of the same year with completly different engines.
Other than the interior, the main difference between the A3/Golf/Leon and the Octavia is that the Octavia has a huge boot.

My understanding was on the turbo diesels Audi and VW get Garret turbo's. Seat and Skoda get KKK's which are cheaper and dont last as long. Even on cars with the same engine code.
Anyone confirm this?
I cant see why they would do this as it would cost them more to have the different production runs rather than build them all the same and ship them out to whatever factory needed them the most.Anyone confirm this?

Might be the first Octavia, but my 58 Superb has the CR170.I'm not commenting on the current range but Audi TDi's used to be different from each other in many ways in the same range of cars with the same power band depending on exact spec. I think there was a point where a DPF engine was 8v and a non-DPF was 16v (or vice versa). Total power output was no different though. It's pretty much b
ks to say Audi engines are better than Skoda in any meaningful way, especially given the price differences between the brands.

The Audi is going to have more of the higher performance engines available on the non-hot models but engine code whatever is the same whatever car it's in.
If you think about it, it makes no sense of them to offer two different CR170 engines at the same time with identical displacement and power figures.
