Hey thanks for the concern. Yes, it was quite a weird phenomena for me as well when I first noticed this 2 months ago during one of my test drives, but I would like to mention a few more things :-

Observations

• Coolant bubbles even after a 10min or 15min or 2 hour long drive.
• Coolant temperature perfectly maintained at 90 Degrees with no sign of overheating.
• A phenomena I witnessed right from the first day and also witnessed it on 9/10 1.0 TSI engines which makes me hope that this is normal.
• Coolant perhaps overfilled from the factory since it was well over the MAXIMUM mark on all of these cars and I really do not understand how Volkswagen's plant would do this.
• I also noticed a similar phenomena on an immaculately maintained 1.2L TSI DSG GT TSI with 23000kms under its belt in 2 Years, making me believe this could just be an operational trait, but at the same time my mechanic friend remarked that it was indeed the first time he had witnessed the same event.

Some Other Conspiracies

• 1.0 TSI is a faulty engine . (I highly doubt so.)
• Cooling system perhaps not properly bled or erroneously overfilled during PDI.

Bubbling or Boiling coolant is not normal at all.
It's a sign of air in system, however this definitely is strange in a brand new car.

I had this issue in one of my cars after hose replacement, and repeated bleeding of system fixed the issue.

If it was my car, I would chase VW till they fix this.

I’ve yet to see this phenomenon happen in a NA engine.

I see, well in that case, that tiny turbocharged engine is being worked like mad to extreme temperatures & pressures (typical for small turbo engines). As a result, because the water pump stops pumping the coolant which stops circulating completely, the engine block is still very hot due to the coolant circulation stops, the cooling fan stops too, the heat continues to build up causing the coolant to overflow to the reservoir.

Which brings me to my next question, is the coolant in the expansion tank above the maximum mark even after the engine is cold? This should be an easy check, first thing in the morning - on a level surface, with a cold engine, the coolant should be at or below the maximum mark.

If the coolant is above the maximum mark on a cold engine, please reduce the amount of coolant so that it’s at or below the maximum mark - https://www.autoguru.com.au/car-advi...erfill-coolant

Precisely my initial reaction!

If VW have indeed designed this to be normal, they have further strengthened my belief that they are designing engines to have a limited shelf life thanks to these ruthless engine operating conditions.

Yes, that was my precisely my first reaction during my first ever experience with this engine when I drove it in July, and yes, this agreeable has been a common symptom depicting air in the cooling system, but presently, I really wouldn't be too concerned since it is a brand new vehicle, with a 5 year warranty, and looking for faults in it, when it is meant to be driven a day at a time, would only distort the peace of mind one purchases it for, and if you've been following my ownership thread, I just got my car back after a windshield repair which took 3 weeks and so I'm really not mentally in a position to chase Volkswagen at present, since the vehicle is not having any heating issues.

On another note, I just completed my Swagat Service and did highlight this issue to them and we witnessed the same phenomena on every other 1.0 TSI engine which was in the workshop for a similar service. The service guys were surprisingly not concerned by this issue, and asked me to enjoy the vehicle.

Yes. I have not noticed this in any other NA engine we have had (1.2L Kappa and 1.2L K12M), but both of those engines had a separate radiator cap and a coolant reservoir, thus making it a slightly unfair comparison. Most of the VAG cars we have (Jetta, Tiguan, Polo) and even other VAG cars for that matter do not have a separate pressurised Radiator Coolant Cap making me believe the cooling system could be designed differently.

As prompted, I have attached a photo of the Coolant Tank taken this morning and I still maintain that I have found the Coolant to be Overfilled (COLD Engine) above the MAX mark right from the time the vehicle was driven out of the trailer, making me affirm that the Coolant was Overfilled at the plant itself. What beats me and makes me wonder is WHY Volkswagen is overfilling their Coolant systems because I have genuinely documented a consistently high number of new vehicles with this phenomena.

The very first time I saw this bubbling was after a 50km spirited drive and that gave me the same impression you had - ' The struggle this 1.0 EA211 downsized engine was having with all the equivalent power from the 1.2L making me worry about it. But that being said, Volkswagen has already rolled out 25,00,000+ EA211 engines (as of 2019) and considering those high volumes, I really hope they have gotten their math and research right.

On another note would like to highlight another specific instance which is a little off-topic but pertains to the TDI engine. You can Google or YouTube Search "TDI Blowby" to find videos of relatively new Diesel engines with dancing, vibrating Oil Filler Caps and smoke emerging from the dipstick. Quite a number of viewers were quick to diagnose this as an Engine Compression issue and even local mechanics said "Engine will need to be overhauled." I'm happy to report that Compression tests on most such engines were hardly negative and the very same TDI engines lived on and are still doing duty even after 3,00,000kms without the need for an overhaul.

I wanted to mention this as my friend's Rapid 1.6 TDI exhibited this blowby and engine smoke from the Oil Filler Cap at 45000kms or so and today, it is still going strong at 2.5L kms out of which 1.5L kms have been kilometres put in after a Stage 2+ Remap. So I'd take events documented on the internet with a pinch of salt, since they could just not be relevant to every vehicle.

My Plan Of Action

1. Siphoning out some extra coolant.
2. Obtaining a DSHA Engine Service Manual.
3. Performing Air Bleeding by the method suggested.
4. Updating the post and thread after the rectification.
5. Seeking clarification from Volkswagen.

Will update some more information after corrective actions, observations and researching more about the construction of this engine which I believe has two water pumps. One integrated in the Thermostat Housing and the other one 04L 965 567 A near the charge air cooler, since they have two unique different part numbers.

That few ML of extra coolant water is not going to make any difference.

After owning VW for a decade, I can safely say; you have nothing to worry.

My Vento 1.6 TDI after service at VW Workshop, last week is showing same level of coolant. Will reduce after few thousands of kms.

Very happy to be able to interact with another decade long Volkswagen customer. Yes, there is good evidence to believe that the extra coolant won't harm. Even our new Tiguan which we picked up last year came overfilled from the factory. Maybe this is to factor in some initial coolant consumption? But I still wonder why the vehicle is allowed to be overfilled when the Owner's Manual also advises against this practice.

The main issue of concern to me and the others was about the bubbling of the coolant after a drive, which could point to air in the cooling system, which is definitely intriguing considering it is a brand new vehicle.

My motive for considering siphoning the extra coolant was to bleed the cooling system and then top-up if necessary, but retrospectively, at 250kms on the ODOMETER, even this concern does seem to be a little too much. I feel there could be no issue at all, since the bubbling stops immediately after the Second Water Pump stops running after 3-5 mins after the drive. It could very well be a characteristic of the new downsized EA 211 Turbo Charged Engine.

You should have mentioned this in the beginning!

What you really should be doing is to read the manual regarding coolant top up specifications and instructions and stick to that!

The manual has very little visual instructions compared to a Hyundai manual but it is thorough IMO. Just stick to all the instructions religiously, especially engine oil and coolant specification, and you shouldn't have much problem.

Ensure you build a good rapport with the service team - VW's internal processes are slow, especially warranty escalations and stuff, as you have experienced. Your friend's at the service centre will help you go a long way!

We couldn't build a proper rapport at the service centre because they disappointed us in every way! It was painful, especially when things needed to be done apart from regular service. Thankfully, we found a VW specialist who hasn't disappointed is thus far!

Hello BHPians,

I have always been in wowed by Polo's whenever I see them on the road (especially in the flash red paint shade).
I had a few questions regarding this car based on the Highline plus petrol automatic model -

1) Is this 2020 Polo available with black + beige interiors anymore? (in the top spec)
2) Is the black plastic cladding along this sides and the back removable (I personally find it a bit tacky).

It would be an absolute delight if any BHP would answer these two questions that I had in the back of my head for a really long time.
Thanks in advance.

my apologies. I replied to the thread asking a fellow users if he noticed the gurgling and coolant bubbling and even shared that I noticed it bubbles after a drive. Diving more into the details through a study of the EA 211 Self Study Guide gave me some more insight about the cooling system, but the general consensus about bubbling let to a scare that made me consider the many possible explanations to the phenomena which was novel to me as well. Yes, I do make it a point to read every car manual till I know everything it has to offer and even though the Polo is a less-complicated product, I did go through the manual entirely. But I could not get any info about this specific bubbling as I feel the owner's manual only specified the Coolant fluid should be between the Minimum and Maximum mark and it did not have any technical details about what should or should not be done if it is overfilled (which seems to be done from the factory), which has raised the questions of whether or not some action needs to be taken in this case.

Yes, I've had a fair share of great experiences with Volkswagen Service and it is all thanks to the good rapport we share.

Having picked up a Highline+ Automatic last month, there is no BEIGE Black interior variant on offer anymore and I believe it is not offered on any variant anymore. I'm frankly not sure about the black plastic cladding along the doors, but there is a good chance one may be able to strip it off for the most part. Not so sure about the back.

Current owners: Since this is a related thread and I could not find any discussion on the topic, I wanted to pose this particular question:

Are the Service Value Packages worth it?

Well I got one for 22K for 2 years (Ameo Duesel DSG) including interior cleaning (2), free pick up and drop, WA-WB, annual maintenance (2) and free inspection (2). All these and more including labour cost.
The below given pack must be good depending on the cost. They have not mentioned the cost on the website. If you find out then please do share here.

Hi,
The packs do make sense and will be cost effective. I myself purchased it for 21.5k (2 services included). The second and fourth service is expensive compared to the 1st and 3rd so this makes sense. In the second service for tsi engine spark plus get replaced which alone costs approx Rs. 3000/-. You will end up saving few thousands.

I recently got a test drive through them for the Polo Highline TSI.


Experience-
Sales rep came home with the car on time
Car was super clean and well maintained with zero issues. The gearshift was butter (how do they do this?)
The sales rep was patient while I took it for a spin around Navi Mumbai
The car stalled at one instance and I wasn't aware that in VW you're supposed to switch off and then try switching on the car again. He stepped out of the car on the road to help with this
Was knowledgeable about the features and variants and gave me a brochure

Cons-
He wasn't enthusiastic when describing the car features. Was very robotic and bored


Now I was also reached out by VW Thane and was setting up a TD with them (I wanted to drive Polo again :P) the Sales guy asked on "When are you planning to buy?" I told him December. Then he texts "Okay so message me in December for TD then" - I felt this was not cool.


Does anyone have any experiences with the Autobahn Nerul or VW Thane dealerships and/or service workshops? I tried finding some threads or posts on this but nothing is recent. I've read horror stories for VW service workshops so really want to learn which ones are the best out here in Navi Mumbai.

Thanks!

I spoke to a PDI tech, the coolant "bubbled" even during my PDI of the vehicle even after a few seconds of the engine being on. The PDI tech said it's just the circulation of coolant and has resulted in no known complications as per his knowledge (to be taken with a pinch of salt then), for what it's worth.

I recently purchased Polo Highline Plus AT, I am looking for suggestions on Rear parking Camera.

The accessories guy at showroom is quoting Rs. 12000, I enquired with him what is the part which he will install.

He showed me Blaupunkt Reverse Camara BC DH01.
I checked Blaupunkt online site and it cost only Rs. 2800, when I told this to him, he said it needs a special socket
to connect to Head Unit and that costs Rs. 7000 and including installation his quote is Rs. 12000.

I seek your advice on this, is this genuine price or should I try at outside accessories shops?

My worry is about warranty if they fiddle with wiring. At showroom at least the blame is with showroom guys if something goes wrong.

Please suggest.
