Possibly leaking injectors?

Hello, welcome to the forum. Do you have what could possibly be the only Skoda in the State - or do you have one of the other brands From the VAG family?

It sounds as if you have a competent dealership workshop, what did the relay unit and fitting cost?

I asked because I'm not aware if the original 1.5TSI issues were ever properly addressed by VAG - rather like the continuing issues with the MkIV.

Note that there are plenty of good quality, OEM replacement expansion tanks available for less than half that price.

Is this a manual or DSG gearbox?

Hello, welcome to the forum. There is another cause for 'sloshing' sounds when braking - check the lower door seals, especially on the rear doors. The drain holes in the lower seal can block, resulting in a surprising amount of water being trapped in the doors. Gently run fingers along and between the seal lips and see if this is the case.

Was the 1.5 so-called 'Fix' usually more successful after a certain year?

Unable to say for the 1.5TSI - but I'd be very surprised if it was supposed to be set significantly higher than the 600 - 750 rpm on my 1.4.

IIRC, there may be insufficient adjustment in the suspension components if the subframe is disturbed.

I'd suggest a full coolant change at the same time - in order to avoid air locks in the cooling system, it's worth considering vacuum filling (or similar) when refilling the system.

As per my post above, just replace the tank - you can get good quality OEM ones for around £15. Make sure the replacement is not 'Mit Silikat' Suggest getting a pair of proper (inexpensive) hose clip pliers - makes the job so much easier and useful for other hose tasks in future (like air filter replacement)

Unless the coolant has become contaminated again - or incorrect coolant has been used, there shouldn't be any staining of the tank.

The simplest way would be to just replace the tank. There are plenty of OEM quality tanks available without needing to buy VAG.

also carefully check the threaded neck of the expansion tank when you clean it up.

Yes, that is what happens if a dashcam is left powered with the ignition off.

One thing to remember, all of the vehicle control modules will be in awake mode, so current drain on battery will be considerably more than just the tv tuner.

Sounds like a good plan to replace the cap first. Make sure the replacement is genuine OEM quality.

I have just realised, if you currently have G12evo, the coolant has almost certainly been changed at least once since it left the factory - IIRC it would originally have had G12 or G13.

Hi, you say 'digital temperature gauge' - is this the Maxi Dot oil temperature reading?

Hello, welcome to the forum. Personally, I'd tend to believe the online spec over the dealer. There is an easy way to test - try switching to HB in an area with good street lighting (without oncoming traffic) - if you need to push the HB stalk forward twice before they switch to high-beam (blue tell-tale indicator lit) - you have HBA.

Hello, welcome to the forum. The fuse ratings are marked on the fuse - replace like for like.

Hello, welcome to the forum. Is there a warranty with this car? if so, I'd seriously consider rejection.

If new service centre does not offer, politely insist on battery condition and alternator output test be carried out as 1st priority.

If you do have G12evo in the system at present - and if that G40 is in fact equivalent to G12++ (check first) it will be compatible. If you do not know if the coolant has ever been changed since it left the factory, suggest a complete change.
