Can anyone confirm that the current 2.0 PD140 engine is, in fact, the same engine introduced mid 2006 through to Week 42 06, when it seems there may have been a change? No one in SUK actually seems to know (yeah, right!).

Check the engine code - usually on a paper label on the engine itself (often on the cambelt cover) and always on the build specification label in the spare wheel well and on the same label which is on the inside front cover of the service book.

Any engine differences, even small ones, will show as a different code.

Beware the 140PS PD engine - it has not proved itself to be as reliable as a well maintained 130 PS 1.9 litre unit.

Cheers Roto... any idea what the code is of the current engine? Are either of these the same unit in A3 2.0TDI? If not, have these been used in any other VWAG vehicles?

Sorry, I bought one of the last 130 PS units - by choice. The code for this engine is AWX.

The codes do read across to other VAG vehicles - I've driven an Audi with "my" AWX engine in it (it was smoother in the Superb - but that was a newer car). Beware, any seemingly slight differences will result in a different engine code. For instance, the same engine for transverse installation as in a Golf will have a different code because the mountings/flywheel and anciliaries such as the fan(s) are different. A NS mounted diesel will have a different engine code if auto transmission is fitted because the EGR is water cooled on these (horrible) models. There are quite a few variants of the 140 PS engine so look carefully.

BSS engine code (2.0 140 EU4) was fitted from 11/05 with a DPF and from 10/05 without so it's not entirely clear. Both also have a 6 speed box.

Only differance in description is -

BSS EU4 or BSS EU4+DPF

And the BSS engne is unique to the Superb as its a 2.0 8V PD, different to any other 2.0 PD which are 16v with the exception I believe of the latter Sharans whichare transverse anyhow.

I wish this was a little more complicated and that way, I'd get in a right mess - as it is, this is as clear as MUD!!! The engine is a VV103KW BSS and its a 7GG.

So what are the issues with the 140 tdi engine, as I have this one with the dsg gearbox

As far as i'm aware all BSS 2.0 8V PD engines are fitted with a DPF.

If I had to guess I'd agree with Ross, you'll probably find that all UK BSS engines have a DPF.

Easiest way to see if you have the DPF would probably be to have a look for the 'gunk tank' in the boot.

IIRC the Gunk tank is underneath, the spare has now been flipped over and the boot floor modified.

Ahh my mistake. Never actually seen one but I seemed to remember the spare wheel bing mentioned.

There was an enormous thread entitled

"dont buy a 140bhp 2.0 tdi superb" or something like that.

The issue was that the DPF (Diesel Particle Filter) gets bunged up,

a warning light comes on, then your car either goes into "limp home" or "shut down" mode.

If your car gets nicely warmed through & gets plenty of long motorway / A road runs,

you'll probably never encounter this.

If you spend a lot of time in slow, heavy traffic,

program the AA/RAC/Skoda Assist rescue number into your mobile!

As mentioned in this thread, the Superb has 8 valves not 16,

so it's a slightly different engine to the Octavia / Golf / Audi etc....

I hope that's a fair summary. ... Darren

OK - I seem to have sent everyone barking-up the wrong tree on this thread!Sorry!!! So, to clarify the questions....

Is my VV103KW BSS engine, installed upto Wk 45 2006 with a CO2 Emission of 173 the same unit as the current post Wk 45 2006 VV103KW BSS engine that has a CO2 Emission of 169?

Then...

Is the VV103KW BSS engine used, or has it been used, in any othet VWAG vehicle?

Sorry again for any confusion...

My doubts with reference to DPF

In 2.0 tdi 140 km is "wet"(additional) DPF in contradistinction to "dry" in Octavia. Im not sure if:

-The catalyst allows the soot to be burnt off at a lower temperature or higher temperature

-The car ECU injects additional fuel to raise the temperature of the exhaust gases

The curent Superb and the Octavia II have two different DPF systems. The Octavia II has a self regenerating DPF as the DPF is mounted directly to the turbo and can get hot enough to burn the soot off. Injection quantities are altered to heat up the DPF when in regeneration mode. The Superb has a longitudually mounted engine. Due to space restrictions they couldnt mount the DPF on the turbo so its further down the exhaust system. The downside to this is it cant self regenerate as its to far away from the turbo so a solution of iron filings is added to the exhaust from a reservoir in the boot. These filings heat up and break up the soot. However the filings stay in the exhaust so over time the DPF will fill up and eventually need changing and the fluid will need to be replaced.
