Superb Engines (are they?)

Jenks · 05-03-2008, 12:43

Is the 2.0ltr. PD TDI DPF engine in the new Superb the same engine as the engine in the current model?

Is the DPF exactly the same as in the current model?

Is the 2.0tltr TDI CR DPF engine a new Engine?

How do the two different engines compare "Pros/Cons" etc.

Is it thought likely, that being as the new diesel engined models are to be be fitted with DPF,s. Skoda will put some effort into sorting out the problems being experienced by some people at the moment on the current model.

I would be very surprised to see any PD diesels in the new Superb - all the newer VAG diesels are common rail.

The 1.9 litre PD was an excellent unit in its time but the 2.0 litre unit which followed was either less good or completely hopeless depending on the version. The current Superb got off lightly because it kept the old 8V head as a 2 litre, but it did suffer from DPF problems (see various threads) which VAG, as usual, have not bothered to fix leaving their customers with major problems.

In some of the more exotic VAG encarnations of the 2 litre PD engines there are all kinds of problems with oil pump drive chains which also drive the balancer shafts. This results (predictably) in drive failure by fretting and will write off the engine when the oil pump drive is lost. If they had used the oil pump to damp the torsionals introduced by the balancer weights (as PSA have done with their gear drive on the 2.2 litre HDi) it might have worked.

It remains to be seen how good the common rail VAG diesels are. The design team obviously had an off season with the later PDs, so if it were my money, I'd buy something else until the newer engines have proved themselves. Buying any new vehicle in the first two years of production is a risky business, especially if its designed by VAG and is not Japanese. It's a pity; I'm sure Skoda will make a fair job of screwdrivering it together.

# I would be very surprised to see any PD diesels in the new Superb - all the newer VAG diesels are common rail.#

According to the catalogue for the new Superb there are to be two PD engines and only one CR engine. Hence my questions.

The link to the catalogue can be found on the thread “ Launch photos of New Superb page 8 #158

Thanks for the link to the brochure. It's interesting to see that VAG are hedging their bets with the diesels, but both of the PD options are SOHC (8V) ie they have dropped the troublesome 16V head on the PD engines. I wonder what they did about the DPF....

# I wonder what they did about the DPF....#

As the owner of a 2.0Ltr 140 BHP Superb with one fitted. "So do I." If they are going to fit them on the new model Superb, surely they must address the problem. Are other engine manufacturers who have a DPF fitted experiencing similar problems? If so what are they doing about the problem?

Surely if your having troubles with the DPF you could just eliminate it?!?

As they've made the engines without as well!

Mmmm! I guess you are not aware of the problems of "Just eliminating it." Have a look at this thread, and several other threads discussing the problem.

Superb 2.0 DPF Removal.

if you can remove the DPF, and fool the ECU into thinking that it is still there and functioning correctly, you might be onto a nice little earner. lol.

I'm going to have a look at the thread you've mentioned. As well as contact some of the friends I knew back at VAG to see what they're up to...

Stuart_J · 06-03-2008, 09:43

The new Superb I believe has a DPF but is a completely different design, at least thats what the helpful guy at Skoda thought last week

As for removing it on the current one Im battling away to find a way. The car comes out of Warranty shortly & once a few outstanding issues are sorted I can start to play. We are working out a system to data log the G450 valve (the bit that reads the dpf) whilst driving & then build a box of tricks to repricate the signal for a clean filter, then we can remove the filter, stick it on the rollers, tweak the map & see what happens. I cant believe that will be the end of it as it uses other sensors as well but you have to start somewhere

skisbp · 06-03-2008, 09:49

Stuart,
Have you tried the VW-VORTEX site yet? As the US spec Passat had this engine option for a short time before the B6's arrived...
I'm on the 4th page of your post 2006ish. Will chime in again when I've something useful to say!!!

skisbp · 06-03-2008, 12:50

Ok I'll try to keep this as concise as possible as I have a habit of bantering on...

Here are a few things I've pulled off WIKIPEDIA:

"In 2004, a powerful 2.0 L turbocharged diesel TDI engine producing 136 PS (100 kW) was added (making the Passat the only mid-sized diesel powered car sold in the U.S.). This variant, sold from 2004-2005, is relatively rare on the used market and examples in good condition command high resale prices for their fuel economy and ability to operate on increasingly inexpensive biofuels."

"As well as offering Volkswagen's older 1.9 litre PD engine, the Superb also uses the new 100 kW 2.0 litre TDIs found in other cars of the Volkswagen Group."

"2 valves per cylinder, SOHC version, developed for VW Passat B5 GP (last editions) and continued in B6 MY'06 with particle filter"

"Bosch EDC 16 / SiemensVDO SIMOS PPD1"

"75 hp 2.0L SDI
Configuration
1968 cc Wet sumped inline four
Head
aluminum, SOHC, 2 valves per cylinder, compression ratio 19:1
Block
cast iron, five main bearings block, 81 mm bore × 95.5 mm stroke
Fuel
multi point direct injection (PD Pump injector, Pumpe-Düse)
Output
55 kW (75 hp) @ 4200 rpm, 140 N·m (103 lbf·ft) @ 2400 rpm
Applications
2003 VW Golf, VW Caddy mk3"

Ok thinks that's most of my supporting material for now.

Following my original feelings which are backed up by some excellent postings made by other members throughout those 10 long pages!!!
I recommend further investigating the removal of the DPF!
I vaguely remember this engine 1st being designed without the DPF.
Yet without any supporting material on this simply retrofitting to that might lead you down a dead-end. So I've included specs of the pre-TDI variation the 2.0SDI above. If you haven't figured out where I'm going with this it's to recommend using mostly VAG existing parts. As opposed to going to the trouble & expense of reinventing the wheel!

Option#2 is to go the other route & attempt to Upgrade to the 16V with all acutrements...
"4 valves per cylinder, DOHC, compression ratio 18.5:1"
"103 kW (140 hp) @ 4000 rpm, 320 N·m (247 lbf·ft) @ 1750 rpm"
"125 kW (170 hp) @ 4200 rpm, 350 N·m @ 1800 to 2500 rpm"

An in length discussion with a knowledgeable VAG tech. Whom comes in day to day contact with these engines. Should be able to tell you which is the more feasible route for your desired results.

Stuart_J · 06-03-2008, 13:02

The hard bit is tricking the cars ecu once the dreaded thing is removed & thats the hurdle we have to jump.

The Passat you describe in the early part of the post cant have had a dpf as running biodiesel in a car with a dpf is a definate no no

Just goes to enforce my memory of this engine without the DPF!!!

Thus if we can confirm this, Then get ahold of this software version & flash

presto no more limping!

Oh other than VWvortex.com could also try Fred's TDI Page. TDIClub.com. VW TDI Enthusiast Community

It wont be that simple, the cars with DPF's have other changes & Im still finding these, as an example it has a longer injection period & this is achieved by varying the cam profil so the downward motion of the pump plunger is longer (thats what irt says in the VW book on the DPF anyway which I guess is aimed at the Passat. Still more research to do

rotodiesel · 06-03-2008, 19:55

This is why the DPF engines are less efficient than the older 1.9 unit. A VAG bodge to get these engines to meet Cat IV I'm afraid.

Burning more fuel to reduce emissions is not very clever.

superb15 · 22-03-2008, 23:21

Sorry for my naivety but i am new at Briskoda.My question is:how many valves per cylinder is in my Superb FL 2.0 TDI 140 BPH with DPF (year 2008) engine code BSS-2 valves(8v) or 4 valves(16v).I have read topic "Superb 2.0 140 bhp -- DONT BUY ONE" and understand that the Superb 2.0 TDI is a 2.0 8V PD (changed from 16v due DPF problems).To my mind problem is omited in manual (just mention 4 cylinders without number of valves) and in the net(even official Skoda site).In my country (Poland) some sites mention 16v others 8v .Skoda is ashamed for too old engine?

Lummox · 23-03-2008, 08:42

You have a 8v 2.0 (BSS).

However as far as I know this is the only 2.0 8V (aside from the Sharan) PD engine. It was used due to space limitations in the 3B Passat originally and then carried over to the Superb (VW thought it was a bad idea anyhow).

All VW 2.0 PD engines are 16v now.

I would have thought with the new car being transverse engined the DPF design will be the same as the Octavia 2 and MK5 Golf/Passat which is self regenerating unlike the BSS engine.

I'm having no problems with my Merc engine, which has a DPF fitted to meet Euro IV. Only annoying thing is the bad mpg I get.

Thanks for yours clear answer

Mine has covered 19,000 miles in 8 months and no "problems" with the DPF. Yes, the warning light has come on once during this time, when I was stuck on the M25 for 2 hours near Potters Bar crawling along due to rubber-necking tourists! Once I got on the open road, it went off and that was that. It normally does it's job in the background around every couple of 000 miles and seems to last for 5 miles or so - you just see a 200 rpm hike in revs and a big drop in MPG during the time it's doing it's thing. My mates Renault Megane has a DPF and he's had the limp-home mode cut in as well as the "get me to a motorway NOW" light come on far more frequently - and he covers as many motorway miles as me. So, now he is considering getting rid of the crappy French thing and going Diesel VRS! So for me, I really don't see these DPF's as offering up a real problem as such - so far for us it's been a really comfortable, cheap and very reliable (touch wood!) vehicle.

There seems to be similar problems with Volvo D5 Euro IV engines - to some extent. VAG, it would seem, are not alone.

Vauxhall and Renault also suffer DPF issues. A workmates Signum was in for six weeks while they were trying to sort that out.

So, now he is considering getting rid of the crappy French thing and going Diesel VRS! So for me, I really don't see these DPF's as offering up a real problem as such - so far for us it's been a really comfortable, cheap and very reliable (touch wood!) vehicle. __________________ Num In Search Of Working Remap!
