They advised to replace the gear oil, coolant flush and the gear oil cooler cover which is estimated to cost approx 40k.

I checked with my trusted FNG and he has said the gear oil does not need replacing in this case as the gear oil has mixed with the coolant and not the other way round.

Can any of you suggest what is the right way. Attaching the photo of the coolant condition.

Your FNGs hypothesis isn't completely flawed, but would you really want to risk the GB for it? The oil serves as the hydraulic fluid for the mechatronics and lubricates and cools the clutch packs. Any sort of anomaly in the oil can cause a failure of the mechatronics and set you back big bucks.

Changing the oil and filter at an FNG is not more than 10-12K. My advice is to just change the oil while you are doing the oil cooler and coolant too. It's a very small price to pay for peace of mind IMO.

+1 to Vishy76

If the gear oil mixed into the coolant, the coolant could have mixed with the gear oil. Only if you can inspect the gear oil, you can be sure that the coolant has not mixed with the gear oil. I guess this has not been done. So it is better to replace both the coolant and gear box oil and replace the seals that have caused this.

Thank you for your replies and I agree it would be better to do it just for peace of mind. Infact the FNG person who is known to me is a very honest guy and instead of fleecing he told me that the DSG oil is in good condition(changed 25k kms before) and not to keep changing it prematurely as in lame man terms " the gear and the oil know each other".
I wanted to double check as I found it strange that a refrigerant meant to cool the engine also flows to the gear box!!

This was common with the mid90s Mercs since the intercooler and transmission cooler were colocated and corrosion sets in allowing fluids to disperse into other channels

Hi fellow Jetta owners. I've recently bought an out-of-state pre-owned VW Jetta Highline and I'm in the process of re-registering the car in Bangalore and have hit a roadblock. For the pro-rata road tax calculation, the invoice of the vehicle is needed and I'm unable to get hold of it at the moment and have been following up with the dealer.

In the meantime, if any of the Highline owners up north (UP,HR,UK,JK,WB,OD) could share a copy of the invoice it'll be helpful in getting the tax calculation and payment sorted.

Regards.

Thought of giving an update on my Jetta TDI (86K). Got the work done in PPS, Hyd. Replaced with new clutch plates, flywheel, C mounting(gearbox?), lower arm, wheel bearing, miscellaneous items. Costed 1.21 L.

For reference - Flywheel/clutch/pressure plate etc assembly costed me INR 78K in 2019 Sep in Bangalore(VW Whitefield ASC). The model & year are TDI 2.0 Comfortline, 2014

Folks, need inputs on this.
Today afternoon when I cranked the car, my AC was not throwing any air. Everything on the instrument cluster and the AC switches was normal except that no air coming out. Tried switching off the engine, changing from auto to manual AC, etc. Nothing is working. Don't know if these are related, but co-driver side window one touch up is also not working from today. One touch down is working fine.
Wondering if it is some AC sensor issue, fuse issue or a rat bite or something completely different.
Model - Highline AT 2014

Please remove ac blower and check. I had major issue with rats entering the blower. Also over a period of time, blower gets stuck. It is easy.to remove.

You are bang on the right part. Took the car to a FNG. Technician did some pre checks and then removed the AC Blower. Seems some internal loose connections inside it. As per him this will work for sometime and may stop again without any warning. New one is above 8k. He fitted back the current one and charged only Rs 100. Anyone in Bangalore who can fix a blower?

Sharing the 8th year 120Km maintenance service @ PPS Motors VW ASC at Hyderabad. The car was bought in 2014 in Bangalore by the first owner, I bought it from him in 2018 when it did ~38K. The 8th year /120K paid service package is about ~INR 25K, additional requested jobs ~INR 11K, GFF and Consumables ~INR 1.5K : Total: INR 37K. The ASC rep recommended changing water pump(as additional requested job). However I expected- Air filter, od.filter, brakefluid, cleaner to be part of 'normal' maintenance schedule, why did they keep those out of 120k/8th year recommended service package, I do not know.

Hi Narasimhan,
Maintaining Jetta at the ASC is too expensive unless it is still in warranty. If you live in or around Khajaguda, there are a couple of Workshops I recommend.
Man and Machine in Madhapur for big stuff like Engine and DSG works.
AR German motors in Khajaguda for normal repairs.
Both are excellent and quite value for money.
