HI,

another riddle:

What does the green-bordered valve do on the BMR?
The photo was taken standing next to the right fender. The valve's operating rod is connected somewhere near the intake manifold or its vicinity...

Awkward counter-question:

Your BMW should have a swirl flap in the intake manifold, right?
...
What do you think now where the rod goes? icon_wink.gif

I almost thought that, but for some reason, I was sure he didn't have one.

I wasn't sure either, but the wheels from Tuneline looked so good on your car... I just had to ask about them.

I think it's great that you are engaging with your new [device/system] so intensely. Even if it is not yet necessary... icon_wink.gif

Does anyone know when the intake manifold switch activates?

Does your BMR actually have an EGR cooler? I once heard that the piezo injectors no longer have an EGR cooler.

Thank you, but I doubt I'll buy another VW again, and probably not a diesel either... After 23 years of owning VWs (plus the ones still to come with my AXR), I'll probably buy something different (... it's good that I said that before buying my AXR too... icon_wink.gif).

Hello everyone,

BMR engines all have an EGR cooler.
The variable intake manifold is needed in the partial load range to provide better swirl of the incoming air.
The valve is for the bypass air duct.
Regarding the question of why use a plastic suction tube, it's about weight reduction and cost savings...
Martin, why don't you just ask via private message? You know the reason.

Best regards,

Unfortunately, the four-legged version is only available with 140 horsepower...

It seems that this is the intended approach within this company. The Skoda Octavia 4x4 was previously only available with a 100 hp engine, but now that the 170 hp engine is offered, it's also available with a 140 hp option.

What is the purpose of having all-wheel drive (4x4) in Germany?

For example, when you have to drive a somewhat larger trailer or caravan.

Or perhaps something more suitable for mountainous regions where you want to be able to navigate well through the snow.

I didn't want to start a "pros and cons of 4x4" discussion right now.

Please don't turn my 16V-TDI thread into a 4motion thread icon_wink.gif.

It appears that not all 16V TDIs have a shift lock. The BKD engine, for example, does not have one, as revealed by SSP 316.

Hi there...

Do the machines perhaps have a different torque characteristic? Or could it also be related to the power output? At 4200 rpm, it only delivers its full potential. For the relatively small valve size, you need aggressive valve timing, and that requires a good Venturi effect at low RPMs. Perhaps this is also related to the emission classification/vehicle weight and similar factors?
