I even heard someone made around 200k KMs with these, i think it will not be healthy.

I was thinking to buy some motorsport style HG coils since they are about 25% expensive, but i guess it will be waste of money at this point.

Remapping the car might be a great idea since a lot of people doing it and the charge pressure is only 0.6 bar with original tune AFAIK. CJZC and CJZD has no differences except the transmission (5sp vs 6sp) and bigger front brakes mechanically AFAIK.

But these undersized engines are prone to oil burning issues and LSPI. EA211 1.2 families have no problems except the oil burning and this makes me a bit reluctant to do remap.

I really hate the delay when pressing and leaving the gas pedal especially at the 1st gear and when driving a bit faster. The delay is literally 2 seconds when leaving the gas and pressing it again. I never race or push the car to limits but directness is important for me.

At 120K KMs, the timing belt will be changed. After the replacement i think i will remap the car but what are your opinions? Probably the coils will be changed at this stage but we will see.

The first marche from April 2014 yes, because the head of the engine had a defect from factory. The guide for the valves were too big.

But after the correction, no issue.

My engine has now, over 200000 km (from end of September 2014)
After 10000 km, the oil level does not move. Even after 15000 km, no need to add oil.

I did my oil change every 10000 km with 0W30 Shell 504/507.

Timing belt is original.

Misfire is detected by difference in engine speed at TDC and BDC.
I also have 30K+ misfires per cylinder. Plugs and coils were fine. Car ran fine, but at idle you feel a little skip.

I then ran CRC GDI IVD Intake Valve & Turbo Cleaner through the intake.
Misfires stopped. Car outran the ESC constantly and was a small pocket rocket. 1000km it calms down again.

My theory? Intake valves not fully closing due to carbon build.
The CRC does an amazing job of cleaning this up even if temporarily. Unfortunately for me right after I discovered this the local importer decided to stop the GDI IVD line and instead import an inferior tree-hugger product from the European market. This one is just naptha, no PEA compound as with the GDI IVD. Didn't work so well and now costs twice as much.

You might want to look into a intake carbon clean.
I need to do mine, but will do it myself. Need to get walnut shell blast media from the local jewellers (the gun shops went mad with their pricing over the last 2 years or so), and then then an adapter to fit the intake ports. There's one for the EA211 on Etsy, but can't bring mysel to buy right now given finances. I do want to look into making an 3D printer adapter, but that means pulling the intake to get a pattern and that's a pain with the cooling system attached to it.

See the shape of the intake port... that bump at the top? Look on the intake manifold where it matches that location. Has flat areas that could be injector ports. The intake is already set up for port injection.
One could modify these engines to have both direct injection and port injection. The intake needs to be drilled, but there is already mounting holes on the head that could hold a fuel rail.

There is one easy way to understand where was your car produced.

The VAG Group uses this kind of VIN algorithm:
First, the country and brand identifier code, for our case it is "WVW"
Then, i guess special section comes and this section is nearly always "ZZZ" in VW cars which i believe means blank, maybe in expensive brands or trucks it can be other story but i have no idea.
Then, the chassis identifier comes. For this generation of polo, we get "6R" (then a "Z" again). For comparison, a golf might have "1J","1K", or a passat can have "3B" or "3C". This surely depends on the car.
Then we have the model year identifier at the 10th digit. For my case, it is "F" which stands for 2015. "A" stands for 2010 and "H" stands for 2017.
11TH digit is the plant number. For EU market, we encounter "Y" (Spain) and "U" (South Africa). For more information you can check the corresponding Wikipedia page. https://www.wikiwand.com/en/articles/Li ... _factories
The rest is serial number for the car and normally for other vehicles (especially japanese originated), lower number means early production but i have no idea about VAG cars.

Normally, there is no prodived VIN checker from VAG unlike Mercedes or BMW. Unless you have the Vehicle ID paper thingy in the user manual and at the trunk, there is no way to check for your equipment. Also, you can not check your build date, only you can estimate from the glasses and production of the parts.

But there is another way actually. By using a paid website called "partslink24", you can check your equipment number and many more. This applies for all cars actually which is very handy. Here is a screenshot for my vehicle information, in turkish.
partslink.JPG

Also, you can check the equipment info but sadly i have no document for that. But i am sharing the list of "factory" code thingies in my car. Normally, in vehicle factories, the vehicle is built with this equipment codes. A single vehicle might consist from 100 and more codes and these are not option codes. Without a single or wrong code, whole system will get confused. This is a bit easier in passenger cars but buses and trucks have crazy list of codes since they are more specific.

Those codes are intended for production and end user has no relations with these. But they are very helpful if you want to have an idea what are you dealing with. It is sad that "VAG" does not give us enough information about our vehicles, at least i want to know the manuf. date of my vehicle.

And since my vehicle is pretty much lacking most of the equipment, i wonder a fully spec'd vehicles equipment list even though they are pretty rare.

How dusty does Turkey get?

I have cleaned my engine bay a couple of times, but the thing never really gets too dirty. Only real problem spots is the frame rails under the battery, etc.

I still want to do a proper clean from underneath and then apply Koch-Chemie MP (Motor plast) which will help make cleaning easier. Also protect engine from external corrosion.

I've someone bring a Polo around here once with a blown head gasket and that thing's engine bay was a complete mess. Maybe people just drive more than me.
