Difference between BSE and BGU 1.6MPI engine

[OctaviaIIOwner]

What are the differences betwen 1.6MPI BSE and BGU engines that were used in Octavia II.

According to data BGU was used from April 2004 to April 2005 and it was the replaced with BSE. But what are the differences between these two engines? Is cylinder head the same?

Also I would like to know, where on the engine is located engine code so how can I check which engine do I have in my Octavia?

Engine code will be in the handbook sticker, or the same sticker on the car somewhere.

Engine has been replaced, so the sticker and the documents are not valid. I need to physicaly check engine code on the engine.

I have checked with VagCom and I get reading that the engine is BGU, but the control unit for engine according to ETKA is for BSE motor.

So physical check would solve the puzzle.

Also I would like to know if engine head is the same. Because on the engine head there are some data.

Couple of things to try:

- Engine number will be stamped on the block somewhere, usually round about the head gasket level.

- Engine change some time ago? In that case the V5 info must have been corrected (or will urgently need to be). Look for it on there.

Then email Skoda UK with the number and a request for more info on the corresponding engine type.

Sorry, can't help on the head differences. Google is your friend.

Although question was 1 year ago, I have not been here for a long time, so I can tell the differences now:

 

- 1 HUGE radiator fan on BSE instead of the double set of BGU (where the smaller one always goes wrong, mine worked for 4 years, the cheap aftermarket had already done more and the price was quarter of the original replacement part).

- EGR system was thrown away (oh those lucky ones with BSE...)

- one oil sprinkler less inside the cylinders of BSE

- no more oil cooler above oil filter on BSE

- noone with BSE ever complained about uneven idling, shaking of the whole body of the car...

- noone with BSE ever complained about uneven idling, shaking of the whole body of the car...

Well, in Slovenia there are a few owners of 1.6 MPI BSE Octavia that have problems with uneven idling.

They tried to solve this with injector cleaning, changing spark plugs, spark cables, etc. Nothing worked. Mileage of cars is as low as 30.000km to 200.000 km. Good thing is that idling of the engine with 200.000 km is the same as the one with 30.000 km, so this is just a feature not a bug that would get bigger :rofl: :rofl: . Though, the idling does not shake the whole body , but you just fell it on your ass . It is interesting that this shaking is not spotted on the RPM meter :think: .

On the other hand, I know an owner of BGU engine with 80.000 km that does not have the idling massage .

Yes, you're right. I tried to find a solution again but I could not find any on the internet forums, but I found some BSE owners with the same problem...

So we can say that it is not an EGR-related problem, since BSE has no EGR system.

 

I know someone with BSE above 100.000 km without any problem with idling.

 

How this can be that noone knows anything about the solution at that ancient engine? I browsed Audi forums, I found complaints of SEAT owners, VW owners - nothing, just the problem description. Not even a suggestion.

 

Not a hint from someone working at VW engine factory, not from a workshop where successfully corrected this...

Is this engine that complicated?

Regarding idling issues:

 

I experienced a rough idle at approximately 100,000km. After repairing a cracked vacuum hose and eventually changing the whole vacuum system, changing coil pack and spark plugs, and numerous scans... the problem remained. Then I went to a VW specialist and he scanned the car again and said the cause was injectors. I told him I cleaned them but he said that simply spraying them wasn't enough. I had to take them out and properly clean them. Haven't done ot yet... but I made a couple of long drives, pushing the car to the absolute limit! The car isles much much better now. My advice is to scan your cars and you should get misfiring codes on one or more of the pistons. The codes will indicate injector issues, wither to be cleaned or changed. Hope this helps.

Hello,

 

I have Golf 6, 1.6, 102hp, CHGA engine code, with LPG, but it's the same like MPI/BSE engine, without EGR valve and MAF sensor.

 

My golf have spent around 300.000 km, and 20k by me, and still run great, without any issues while driving.

 

But I have the same problem as above, shaking on idle sometimes, but revs are stable.

 

Changed many things, all tested and changed by me.

 

What I have tried:

 

Changed brand new:

• LPG injectors & LPG Map sensor about LPG pressure
• Lambda (Oxygen) sensor (first one before catalytic conventor)
• Spark plugs
• Ignition module/coils
• clutch pedal and used whole manual gearbox (5 gears).
• all filters/oil has changed on time (both, Engine and LPG filters)
• Belts/bearing on time

 

Maintenance/Cleaning/Check:

• Compression test excellent (that means valves are ok, also great pointer is that the sparks are not oiled or burned/dark )
• Vacuum valve - Cleaned & checked
• All rubbers/pipes on air intake system - Cleaned & checked
• Throttle body - Cleaned & calibrated
• Map sensor - Cleaned & tested
• Other diagnostic test like read realtime sensors & parts variables (I have many device including original VCDS)

 

After all stuff above, the problem is still remain. Talked with many people and read on every forum and conclusion is that the problem is very often and has not real solution. Many owner say that the engine simply works like that and forget it about changing parts and waste your money, in other ways, the positive thing about this engine is that the maintenance is fairly cheap and engine run well.

 

Because I have petrol and LPG, and the problem still exist on both fuels, I can exclude petrol Injectors and Fuel pump as possible parts to search for the problem. Also flywheel is not dual-mass, my opinion is not space to search for problem there, like many people does.

 

The only thing that partially works for me, it's up revs to 820-830 by VCDS tool ( that is the same as you turning on your AC because in that moment your revs raise) and idle going to be more stable and shaking become fairly calm, but idle fuel consumption raise up to 30% as well.

 

If someone have another experience and resolve this problem in other way, please share experience here.
