Hi,
From what I can make out from the diagram, it is a plain water cooled intercooler. What is 'Chemical Intercooling' about it? (From what I know, might be wrong, 'chemical intercooling' i fanciful jargon for fuel (usually methanol) injection just after the turbo.)

Well your right actually.. its more like coolant intercooling. Though if you use a stronger coolant, the results improve.... power bump and better boost hold.

Hi,
What is a 'stronger' coolant? (Eg. please.) Does it run cooler? If so, how and why?

Dude, I'm really sorry, but I don't buy your 8.08 second time! It definitely doesn't feel like an 8 second car. And gains of nearly 2 seconds on 97 vs. 91 octane is unbelievable.
VAG officially claims 9.6 seconds. It would be possible I suppose to get that down to between 9-9.2. But anything more than that on a stock car is crazy.
What was the surface you were on? We're you going down a slight slope? Any significant winds?
Are you giving us runs in one direction? Or did you do runs in both directions and take an average?

One direction. Slope dont know. Better tires, lighter wheels (1.9kg off every wheel) and on 97, tcs off, no spare wheel. Quite possible. I was also surprised by the timings so I dont blame you for being sceptical. Also car was in S mode with short shifting thru paddles at about 5200 rpm. Will do a video next time.

Have you managed to install the dead pedal. Can you share pictures and experience of installation.

The new cluster looks good - classy as the Laura. I love white over black dials.
BTW, my Laura has this coolant level sensor. It will be worth checking if you can take the Laura one (the bottle, sensor, wiring, etc) and retrofit in your Polo.

Prithwi, sorry to hijack the discussion but could you tell me what should be the ideal life of clutch packs on your DSG and does it really vary much with spirited driving (especially after VW said that they have made some changes to the box to suit immense stop and go Indian conditions)?

Also, please mention if there is any oil change schedule for the DSG and if yes then what is the interval/cost associated with it?

No idea. First DSG car I've owned.

Usually from reading on various VAG forums DSG clutch packs last quite a bit, even if ur doing crazy driving. Most clutch pack replacements have been reported around the 25k miles mark which is ~ 50k kms. There is little scope of damaging or burning out the clutch unlike in a manual. DSG prevents accidental downshifts in manual mode, an even if u do downshift from 3-2 at 4k rpm, the car rev-matches (brings the engine RPM to match the transmission gear rpm) to prevent damage to clutchpack.

Only increased wear IMHO comes for 1-2 gear bumper to bumper traffic, where the car is slippin the clutch in 1 to get the car rolling. I suppose we will find out how much the clutchpack lasts.

From what I can remember Sparco Wheel Weight incl tires is roughly 9.4kgs. Stock is around 10.8 kgs. Donno for sure. Sparco Alloy weight alone is around 7.5kgs.

Thanks for your prompt reply. What I also wanted to know is does the manual suggest any periodic change in Oil for the DSG like the 6-speed DSG gearbox found on the diesel variants?

The 7 Speed DSG (DQ200) is a dry clutch gearbox, so I guess there is no oil change there.

No. The clutchpack is dry, lol.. transmission is still wet.. so yes, you will need gear oil.. try driving a car which is low in tranny oil.. terrible experience.

Dead Pedal Install Process - A little more complicated than you think.

Step 1- Remove the plastic clip/nut on top of the trim next to the steering column cover on the floor of the car. (to find out which, align the pedal on the floor and see where the top hole aligns to. Fix the foam backing in the plastic holder and put it in place so that the top hole lines up with the mounting point above the pedals. You will see that the pedal sticks out from the foam moulding a bit. This is OK.

Step 2- draw an outline on the carpet (covering the floor and transmission tunnel) of the pedal.

Step 3- cut the carpet out and expose the metal floor and transmission tunnel.

Step 4- fix the foam part in place on the exposed metal using any glue/3m tape of ur choice.

Step 5- Put the carpet back around the foam moulding. Fix the dead pedal on top of the foam moulding, bottom part clips into the foam moulding, top part aligns to the screw on top which gets covered by the nut.
