Is the BMM Engine worth it?

Featured Replies

After a lot of looking I have found a scout for sale (used) which ticks most of my boxes. The engine is the BMM which I understand is 140hp 8v PD.

How do these engines rate for economy, torque and lag compared to say the 16v PD (BKD) and the later 2.0 CR of similar power? I have heard they are significantly noisier, but the car is for sale in a distant location.

Are there any expensive concerns with a 2010 vintage (probably 2009 build) scout with this engine and the manual box?

Are these really still a reverse-flow head with the intake and exhaust on the same side?

My wife averages 39mpg which involves a 10 mile run to work via the childminder. Engine barely reachs operating temperature during the winter months.

When I've taken it to work (65 miles each way) I've managed 48mpg.

These are both calculated manually as the onboard computer quite happily tries to tell me I'm doing well into the 50's!

I think the fuel consumption is great considering the extra weight and 4x4 drive system.

I don't think it's noisey.

The turbo (which I'm led to believe is a weak point on the BKD engine) is supposed to be more durable.

The only disadvantage is the BMM gets a DPF (Diesel Particulate Filter) whereas the BKD doesn't.

I wouldn't hesitate buying another BKK used Scout tomorrow, in fact if I had the cash I would.

Thanks for that, very helpful. Is your wife's car a scout?

I like the rest of this particular car, but IMO the price is far too high. Equivalent of 18,000 quid for a 2.5 year old scout with 45,000 miles. I could import a new one from the UK for similar money.

Yes, the wife has the Scout, I have the vRS.

I bought the vRS last year, I wish I'd bought another Scout. When I drive the Scout it feels so much comfier than the vRS and its so much easier to drive smoothly (and therefore effortlessly).

Scout prices here in the UK are crazy, see here:

This is the main reason I'm not prepared to trade in the vRS, Scouts are asking too much money and dealers won't negotiate.

I take it you don't have Seat's Altea Freetrack 4 over in New Zealand?

This is the Scout with a different body (same plastic body mouldings) and the VAG PD170 diesel engine and are HALF the price!

170bhp + Haldex 4x4 = lots of fun and a very capable car. No good for me with it's poor fuel economy.

Th vast majority hate the way it looks, I actually love it!

Sadly no Seat's. Wish we did.

So when did they swap from the BMM to commonrail?

2009, at least here in the UK.

Just following up on Silver's post I can also vouch for the BMM engine. I have a 2.0TDi 4x4 with it and so far the only real issue we've had has been DPF related after roughly 5 years and 36,000 miles (the more recent of which have generally been town related and short journeys). It may be that the issue was a sensor issue but, having had this fixed I can certainly vouch for it's driveability. Economy is pretty good - on a 'motorway' run I get high 40's pretty easily but this drops in town, the torque is excellent and, in terms of lag is better now the DPF has been removed. The latter makes the car much more petrol like in delivery and smoother overall.

It possibly is noisier than the CR engines but the PD always was a bit rougher (that's why the PD engine was phased out) and the Octavia Estate, being a big box, tends to emphasise things a bit.

The only thing that used to catch me out is the gearing on the 4x4 6 speed box - 1st is pretty low but I'd bet is great for towing!

Overall though I see ours as a 'keeper' and have no intention of changing it or moving it on - which may be one of the reasons the used values are so high - most owners think the 4x4 and Scout and damn good cars and are reluctant to part with them.

My current train of thought. I'm not opposed to the BMM engine, just opposed to spending 3/4 of new car money on one. I guess it's a safe bet that any earlier 2.0tdi scout will also be a BMM.

Time to start hunting for fleet disposals I think.

Any pre-facelift Scout will be an 8V PD140 DPF (BMM).

The PD engine was also used on the phased pre-FL to FL Scout (pre-FL front end but FL wing mirrors, interior and rear light clusters/badging).

The PD engine was also used on the early FL Scout's (2009/2010).

The CR engine was introduced during 2009 and is only available in the FL Scout.

I've driven the BMM Scout, a BKD Elegance and now a common rail Scout. I preferred the BMM over the 16v BKD engine - seemed more refined. I live in London and had the DPF light on once (it had been a demonstrator) but then not again for the two weeks I had it. I still miss the power delivery of the PD engines.

Just bought one sight unseen. Price was right.

Any pictures from the advert?

I'll post up some pics when I actually get it. Probably more than a week as it'll be transported.

But for now I can say it's a shiney black pre facelift scout.

Black was my second colour choice, I prefer white for ease of cleaning and reduction in summer heat. But this will look very cool when it is clean. Company signwriting only works on

What were the changes with the facelift? Obviously grille, front guards and headlights. Any mechanical or interior changes? I haven't see the build date but registration suggests it would be near the end of the pre-facelift cars.

Externally the facelift gets new headlights and grill, new rear light clusters (removal of the integrated red reflector strip), new badging on the boot (latest font) and larger wing mirrors.

Inside the centre console is different (touch screen Bolero radio head unit with SD card and a new heater control panel), a new steering wheel and dials/clocks. The rest is the same as the pre-FL.

There were also a few extra cost options added including LED DRL's in lieu of the front fog lights and polished proteus alloys (gunmetal grey spokes).

I see repeatedly misinformation and confusion of common drivers.

 

turbocharged cars are not designed for short trips. TDi engine needs at least 30km to operate at optimal temperatures (ambient temp around 5deg C). 60km needs transmission to warm up.

 

DPF as above by

BMM engine has been designed for fuel economy and it is also younger sister of vRS.

 

BMM engine has got great fuel economy up to 2000rpm; it is beast at around 3500rpm

Got any evidence or statistics (preferably peer reviewed) to back up this assertion?

just check the forums ;-) common outcry...dead DPF - it's expensive; BMM is rubbish it won't drive like F1 at 1500rpm; why is my turbo dead after just 20k km.

 

years of repairing cars; years of racing; years of myth busting. years of listening to e-experts and authorised car parts exchangers ;-)

Just check out my page. My cars last 300+k km and they are in better shape than much younger cars ;-) Everything around you is just a reflection of its owner.

So that's a no then.

I've had mine for about 3 years and the majority of trips are under 30km/h.  The engine is warm in summer within about 4km.  In winter (below zero) it would take about 15km to reach 90C water temp.  I run a carpet square over the intercooler in cold conditions which raises intake temps by about 10C and shortens warmup distance by about 1/3.  I had to replace the DPF pressure sensor (like all VAG diesels that year) and otherwise zero engine issues.  My car is almost 6 years old now and I have a custom tune with EGR shutdown and timing slightly advanced.

 

The BMM wasn't really designed for anything.  It was an evolution of the earlier 1.9tdi with the same reverse flow head.  Slightly bigger pistons fitted, a better turbo and a better intercooler to deliver more power.

 

My fuel economy long term average is around 6.3 litres/100km.  Best ever was 4.7 per 100 on a slow and slightly downhill trip stuck in holiday traffic.  On a flat road at 100km/h it is around or just under 6 litres/100km.

Don't worry guys. You've no idea what is going on. Whole system is based on people like you.

It's alright, I'm not worried.

2009, at least here in the UK.

My scout was built in April/May 2010 and was one of the last PD engined ones. I would highly reccomend this engine. I've had no DPF problems despite it being used for short runs.

The only problems I've had are broken springs (front and rear), difficult reverse gear when cold and a stiff handbrake.

Averaging about 43mpg.
