Coolant Leak - This May Help
Guys, I seem to have a similar coolant leak to the one described above, as in using about 1 litre per 6 months, but I have just found the cause - It also came to my attention, as the better half complained she had no heating, even when climatronic on HI, although cold A/C was fine.
In my FR TDI, there are what I believe to be the flow and return pipes that pass through to the heater matrix, down fairly low right in the centre of the firewall. Looking from the engine compartment, towards the top of the metal pipe, but before it is connected to a rubber hose, there is a form of bracket with a nut through it, where the leak appears to have come from.
I haven't messed around with the bracket, as the car is just in warranty, so that'll be fun then!!
Anyway, it may be worth checking, as it appears that this could be caused by vibration, which I assume has physically fractured the pipe, as there is no obvious connection at the bracket, it just looks as though the pipe is bent.
Is there a common(ish)
problem here, or am I just plain unlucky - Whatever the outcome, I'll let you know, as I'm assuming it'll be a dashboard removal, and possibly part of the engine, as in mine, there ain't much room.
By the way, I forgot to mention, that as the coolant is in contact with the outside of the pipe, it has crystalised, and there is a large amount of distinctly pink (G12+) running down the pipe, and in through the firewall, so get your torch out, and look for the pink!
Hopefully gonna take it in to Kings Seat Portsmouth, as they've always been top guys, and never quibbled, unlike the scrotums at my local stealership.
Have a look at the following photos - sorry for the bad quality, but I couldn't do much better with a mobile and a torch at 22:30 last night! - Guiness, I hope these
help you pal, cheers.
