The Mega Mk7 Golf GTI/GTD/R thread

The thermostat housing is plastic and has a tendency to warp, its mated to an alloy coolant pump and the mating surface on that has a tendency to warp too. They are a balls of a job but fairly common to go.

Dealers will never replace the two at once though so I'd nearly find out what one is leaking and pay for the other component myself or you'll be paying for the full job down the line.

Do you have a DasWelt Auto warranty? They dont cover leaks, if the selling dealer is sound they should cover for you regardless but if getting the work done at a different dealer you might have grief.

This is good advice. I’ve seen it so many times on these where the dealer sorts one leak only for another to develop soon afterwards.

Oh yeah? They only seemed to mention the thermostat, so I should be asking them to do the "alloy coolant pump" as well?

Oddly enough it's not the buying garage, and they had no bother doing it under warranty seemingly.

Depends, manufacturers warranty will cover it but the DasWelt used car warranty doesn't, or at least shouldn't.

I forget how much the pump is but I'd definitely be doing it at the same time, they are known to leak too, so you might aswell get the labour for free now. Particularly if you plan on keeping the car a few more years.

Do these problems affect the Mk7.5 also or just the Mk7?

Mines a MK7.5

I didn't find it anything major, light came on in the middle of nowhere, topped it up with some water and drove on. Fixed under warranty, no issue.
Other cars have broken my heart when that light came on, BMW it's a head gasket, if it's a Subaru you cry.

I asked them about it there. He recommended I wait and don't do it until the timing belt is due (5 years is the interval right? 162 car so it'd be due at the end of next year)

Does that make sense? Basically said there's no point in doing all of it yet.

Time to find another dealer for servicing I think. Clueless.

It's literally attached to the thermostat housing, it'll be removed to do this job which is a good few hours labour. Its driven off it's own drive belt, not the timing system. Might be worth asking them to reconsider unless you think you're banging your head off of a brick wall.

@SH,

In fairness the usual and often only symptom is slow coolant loss, you wouldn't be able to spot the signs of coolant residue at a glance on a dealers forecourt or anything as the components are well buried in the engine bay.

It will effect anything with the 2.0TFSI, fast Golf's, Cupras, Audi TT.

Would you need to be worried with something in the lines of 181 with 20isk k km? Or it's just a think that will manifest even on almost brand new car.

The Mk7 R is no more, I assume this applies to everywhere.

Really?
I have the button and don't have DCC

I thought it was standard, this is the first I've noticed without it

I think Driver Mode was an option back then.

It was, Joe had to badger Western Motors with the option code to get it added to his R at the time back in 2015

Another GTI with the mode button but no DCC here (162, model year is 16). I was quite disappointed when I realised it didn't have it because I thought all GTIs with the button had it.

I've driven one with DCC and it's a really nice extra. Subtle, but you'd notice it. Possibly the only extra my current car doesn't have that I'd like it to.

What does the mode button do if you’ve no DCC

In the GTi/GTD switches driver mode between Eco/Normal/Sport/Individual.
In the R switches driver mode between Eco/Normal/Race/Individual.

The individual mode lets you alter the settings like throttle response, steering feel etc. Without the DCC it obviously doesn't alter the suspension.

Race mode in the R opens the valves in the exhaust. Not much difference between Normal and Sport in the GTD anyway, improved throttle response and the soundaktor gets louder, which reminds me i think i'll get it coded out in the R.

Agree with this hooch. Eco mode is about as useful as tits on a bull in the R.

I will say though that in my R with no DCC, eco mode feels like the suspension is “squishy” on hard bends. On the few occasions that it was on and didn’t realise it (after going around 1 particular roundabout the car felt it like it was under steering When it shouldn’t have had and I realised it was in eco...) - this might be just bias confirmation, or else, MAYBE just going too fast
