Coolant leak

[wai]

My TDI has done the same thing. Einstein at the dealership has pressure tested the system and says it's fine, he went on to say it's a common problem with the TDI's - I'm not entirely convinced, this is my 3rd TDI and it's the first one to use coolant.

That's the standard "standard for this type of vehicle" rubbish that you get from the dealers these days. In other words, the customer has to prove that there is a problem because they are not going to do a thing about it.

It's the usual dealership cop out response. Generally translates to "yeah we see what you're talking about but it's too hard to do anything about it so we will wait and see what happens. If it gets worse it should be easier to find the problem".

I'll be monitoring the coolant (and all other fluid levels) very closely and the dealer will be seeing a lot of my car until I am happy with it.

Went to the dealership and got the we will monitor it as we could not find the problem... Useless

I've found in situations like that, you need to have the system pressurised above cap pressure, and left overnight, and keep re-applying pressure until you spot the leak.

Hi all.

I got a Coolant Warning in my 'bought-new-in-Feb-Mk7 GTI' last week along with leakage (resembling fuel) on my garage floor same day. I promptly booked it in for a going over and the diagnosis was it needed a new fuel pump. I Googled as you do and see this is a known issue with older Golfs.

I have no mechanical know-how and I am basically hoping for a Dummies type run down of the issue and what it means for me and so I know what to say to the dealer tomorrow when I hopefully collect the car (it's been there since Thursday). A friend suggested the dealer will need to flush out my fuel system as it may have been contaminated. This sounds alarming.

Any advice would be appreciated. Thanks in advance.

Just say; "thanks for fixing my car"

Water pumps failing were a known issue on the mk6 GTI - mine is on its 3rd waterpump in 60k - the problem was supposed to have been fixed using an updated waterpump - but there are always parts that are one-off failures.

What Transporter said.

They're honoring the warranty that's built into the purchase price of the car. Not much more they really need to do.

Hang on, is it a water pump (as per the subject line), or a fuel pump (as per the body of your post)? These are two very different things and are in no way related.

The water pump is used to pump water/coolant around the engine block, whereas the fuel pump is used to deliver fuel from the tank to the injection system.

I suspect it's the former, in which case you will need new coolant (which will of course be done as part of the replacement work), but your fuel will be completely unaffected.

thanks for the replies.

collected the car yesterday. unfortunately it is back in tomorrow. see below.

just to clarify, I was advised it was water pump / coolant pump (I assume it is the same thing, not sure why can't they agree on the vernacular, spoke to two different people on drop off and collection).

Unfortunately, i was provided with no paperwork upon collection. this may have been an innocent oversight however i will say
the guy i dealt with at South Yarra VW was a complete a$$. rude and dismissive. told me it was "no drama" that my car had been with them for 5 days. this sort of thing never happens to VWs apparently. was expecting a call back from the service manager today which never came. i will follow with him tomorrow and also re the paperwork.

in any case, the car is back tomorrow as upon collection the left pass window and door is now a creaky mess and in addition the glovebox falls open at the slightest bump (no less than 8 times going home from the dealer, 6 times day on the commute to work).
this afternoon my front parking sensors were going on and off at whim.

feeling a little less love for the GTI today it must be said
