Current Octavia has third generation of the EA888 TSI motors. I am not sure, but from the pictures it seems that the water pump placement / construction / drive are similar to that of the 1.8TSI in Laura.
A4 1.8TSi has longitudinal engine! Interesting!

Whether the water pump is driven by timing belt or something else (like in case of 1.8 TSi) has nothing to do with combustion system and fuel type, IMO.

BTW, in case of the Tuc, I got no warnings on the instrument cluster, even when the parking guy showed me the leak, temperature gauge hadn't moved at all from the standard position, so I was lucky, I replaced the pump before the engine overheated even once.

And for any such critical jobs, I will never give my Laura to any FNG. In the 6.5 years and 45000km that I clocked on the Laura, she has strictly been serviced at the dealer. Only wheel balancing and tyre rotations have been done outside, but that's me, I don't know of any FNG who really know the 1.8 TSi engine so I don't risk it even though the dealer rates are high (but then it is the case with Hyundai as well as I have seen in the 8 years of my Tuc's ownership). Maintaining cars is expensive, no doubt.

Like mentioned in my previous post, the water pumps in the 1.8TSI are advanced units compared to the ones in 1.6/2.0TDI engines, located differently and significantly more expensive also. The assembly contains the thermostat unit and the coolant temperature sensor. Also when working properly, they are for the life of the engine (ironically) unlike the units on the diesels where they are replaced with the timing belt. Quote of 19k for the water pump seems to be fair, considering costs here in Europe. The pump with a history of failures, has atleast 3 part revisions post 2011. For reference, the current part number revision for the coolant pump should be either of 06H121026DC or 06H121026CP.

Labour involved in replacing the pump in 1.8TSI will be more than that in the case of 2.0TDIs. Because of the pump's location, replacement requires removal of intake manifold and other bits in front of the car. But 5k as labour definitely seems far stretched. So is 3k for coolant drain and refill. Insist on the ASC to use only standard labour codes.

If anyone is interested, attaching the self-study programme document for the EA888 1.8TSI engine's basic architecture. Good read. Regarding the coolant pump in discussion, from page 30 of the document. Attachment 1573927
Excellent info Avinash, thank you! Will surely read it.
BTW, any idea where the engine oil really goes in the 1.8 TSi (Laura)? It's not alarming, but in last 6 years, I have never clocked even a single service interval without having to top up. And I don't even clock 15000km between services. It's anywhere between 8000 to 10000. And the tail pipes have a black carbon deposits! Same is the case with Polo TSi. What's the story, any idea? Thanks again

Thanks!
Hi Anand, I also had same issue with low beam projector lights, while my visit to sainath auto ultimate in khar suggested me to upgrade lights to HID's and this can have good impact. He told me that this will cost me 6K. I have not taken specifications of bulbs but I am incline towards the upgrade.

I plan to visit him next weekend let's if it work out well.

Yup, all Audis from A4 and upwards, whether FWD or Quattro have longitudinal engines. Among them 1.4/1.8/2.0TSI essentially are the same engines that do duty in the affordable VW/Skoda cousins.

I honestly don't know the reason for the higher oil consumption in 1.8TSI (it is the case with the engine globally). Some suggest that it is due to inefficiency of the the Positive Crankcase Ventilation (PCV) assembly (also refered to as the oil separator / breather etc), which sits at the top of the engine. If the oil separator (part of PCV) is not doing a proper job, you have more of the oil vapours going into the combustion chamber than normal, possibly increasing oil consumption. This PCV is also a common faulty component in the EA888 1.8/2.0TSI engines (along with the likes of coolant pump, timing chain tensioner etc), and has seen three part revisions. You can read about the PCV in our cars from page 24 of the previous document.

In our Laura, the PCV was replaced couple of months back due to 'system lean' faults being recorded in ECU. Post the replacement I feel that the car idles smoother, and will also be checking if it is bringing down the oil consumption. Other reasons for oil consumption could be our fuel quality (thereby different constituents in crankcase vapours), but that is just a wild guess. The tailpipe carbon deposits needn't be burnt oil. Direction injection petrols (likes of FSI / TSI) do produce soot which is otherwise normally associated with diesel engines. Combine that with our fuel quality, the deposits thus could similar to what we normally have in diesel tailpipe. This soot/Particulate Matter is not an issue with regular port fuel injection petrols though.

On a separate note, I have observed that the 1.2TSI (in our Vento) as well as the 3.6FSI (Superb) don't have similar oil consumption patterns like our Laura. The Superb seems to be having the least consumption rate, slightly higher for the Vento, and highest in the Laura. I keep spare bottles in the boot of all the cars though, luckily all use the exact same grade.

I was waiting for the ABS sensor kit to arrive and as posted in the log earlier, it indeed was the fault in rear right speed sensor. Got all 4 of them replaced for 8K (Parts + labour) with 2 year warranty under 70% discount scheme still applicable. Actually it was much cheaper than outside, many of whom quoted ~4K per sensor + labour.
All the DSG related issues too are now sorted!!

My Laura has the ABS Sensor error and has to be replaced, where did you purchase same? I'm sorry if you have mentioned it elsewhere.

Btw just changed by Laura 2008 Clutch Assemby and Front Wheel Bearing along with Timing Belt, costed me around 80K for all the above.

Need to change my roof lining and ABS Sensor, and I think my car will be back as new

I gave it to Autobahn Skoda - Mumbai as mentioned in the Bill.
