Matrix has gone (misty/ grimy windows, no heat, header tank low, damp pass carpet!) and just ordered new one from VW Heritage.
Can I get rid of the bypass or am I better keeping it? Happy to order new hoses and do the lot at the same time if needed. Car was blowing warm a week ago so I am assuming that the bypass valve is still working. Any way to test?
New part is listed for mk3 as well so guessing it will be up for increased pressure?
-
I got rid of mine when I changed the matrix, just to tidy things up if nothing else. The heater will burn my face off now.
-
Thanks for that. Will source some new hoses to tidy the engine bay. Any ideas on part numbers?!
-
I need to do this too, cold mornings are getting a little hairy...
-
Some suggest using a mk3 matrix along with the straight pipes. The bypass was a dealer fit/recall so isn't listed as a part. You could replace the bypass with copper pipes then see if the temperature changes that way you know it's the bypass. I'm sure Heritage list the straight rubber pipes.
-
the bypass was a safety feature fitted to prevent the heater matrix bursting and scalding your feet badly! would leave it where it is tbh.

So it's either freezing toes or scalded ones? FFS.

oh the irony :grin:
-
I believe the mk3 matrix is a better / strong design so the bypass valve is not needed.

Quite right. The original matrix wasn't up to the job, so rather than VW changing however many millions of them under recall, they fitted the bypass valve instead. It's all down to economics.

I called VW Heritage late this afternoon and the tech guys there have said it is fine to remove the bypass with their matrix fitted. Will get hoses sorted next week and try to dry out my carpets in the meantime! Bloody coolant everywhere......
Have managed to lose my profile in the meantime, though, having updated my email! Waiting for JV to log in and hopefully put the world to rights......

I really like my toes unscalded. But I also really like the ability to see out of my windows. Is there actually any real danger removing this valve? I mean, we are driving cars without airbags, we are pretty much dare devils by modern day standards anyway...

Their is absolutely no need to run these valves after a Matrix swap! a new Matrix is made to a far higher standard than the old line fitted items, and is not likely to burst like the earlier versions!
Proof being that the OP's Matrix is only leaking, and not burst, just like everyone else's that comes on here, and other Forums...
However, I would only recommend removing the valves AFTER fitting a new matrix, just on the unlikely off chance that the Matrix is still the factory fitted item!

Well if I'm honest I don't even know what is wrong with mine, it blows pretty weak room temperature air. I fitted a new fan as the old one was unbearably noisy so was expecting more air blown at me regardless of temperature, but nope still just a trickle of mild air. A new matrix looks like a ball ache of a job, will it solve my heater woes?

There's probably nothing left of the control flaps inside tge heater box.
Just blows on feet after all the foam has blown out of the vents.

All sorted, back on original profile!

If you are replacing the matrix then have a look at the flaps in the heater box. For some reason the flap has holes in it covered with foam (I think). The foam breaks down making the flap useless.
Changing the matirx is a ballache but worth it. Have a read: http://www.clubgti.com/showthread.php?265347-Heater-Matrix&highlight=mk2+heater+matrix

Love how some people say it will burn feet. They are small radiators in a plastic case. WUSSIES :grin:
As Thom and dragonfly above.

RIGHT- :angry: :angry: :angry: The lower securing bolt is turning in the engine bay although the upper one came off really easily (both had WD40 for 12 hrs in advance). Any option but to cut it off? Right pain....
Also cannot get the plastic nut off at the blower end- should it unscrew by hand? Either I am really weak or am missing something! Pipes are off in the engine bay and am replacing the header tank at the same time, but it is just that lower bolt!!
