Picking this 1.6fsi up Monday.

Must be a thing with 1.4’s as our heater fan constantly hunts. Not had chance to investigate it yet.

The heaters are a bit random - of the five cars we've got at the moment three work and two definitely don't - but next week the ones that don't work will probably start working again :eek:

Annoying for sure and your very lucky if all of a sudden they start working mysteriously. ;) I believe it's the fan control module that's the culprit in these cases.

Also, vigorously exercising the flaps helps*. Finally, I have access to VCDS which you can run a cycle to help.

WOM did a wonderful job lubricating the flaps on both Baby Boomer and Project X.

*This is NOT a euphemism ;)
 
That last sentence of yours has all sorts of connotations. :eek:

How on earth do they Lubricate? I'm pretty sure our 1.4 has a faulty fan control module as it will all of a sudden work briefly when we go over a particularly bad rut in the road.

Ask Rob or Marcus ;) I know @Special edition has had a similar procedure done and he was happy with the results...

Anyone who has worked alongside me in a mechanical context knows full well that I can quote procedures very well, but I'm not at all practical ;)

I had the temperature control flap motor replaced Jeremy... I think that this fault may relate to the fan motor.

I agree with that.
This motor tends to "seize", thus its controller stops powering it to preserve it.
Dismantling the motor housing, then the motor from its housing and lubricating it is doable, although a bit fiddly. Plan 1 to 2 hours.
It has been done and reported here.
From experience, it's not a temporary fix, it lasts for a few years.
 
@Vorsprung durch Technik I just spotted this thread (not sure how I missed it). Did you get to the bottom of the FSi issue? was it as @BoxyA2 suggested the vacuum solenoid or was it the actuator at fault?

I've got a whole thead on my FSi diagnosis so the more information I can get the better. Lovely car BTW! Do you still have it?

Thanks, yes i still have it, seams i'm a rare breed on here in that i like to keep my cars for a long time. The Green Goddess

It explains in the thread what i had done to the car. I've seen your thread and am watching it intently as it's the most in depth how to thread on the why's and ware fores on the Fsi system. Keep up the good work! :)
 
Cheers buddy! I'll keep going until I get the answer, there is a lot to this but I'm dedicated as having had a beautiful FSi (the Blue colour storm) I can appreciate when they are going well they are quite literally the best A2 I have driven (including the remapped TDi 90). They cruise so well and pull hard when needed, all with excellent fuel economy.

Knowing you the FSi will be all fixed now, but I didn't see in the thread what you did to fix it?
 
At last a member of some years on here who truly appreciates the fsi. I've mentioned it before but the car feels like it has a small turbo charger in that you only have to push the accelerator peddle a few mm, hold it there, the car just keeps on pulling vigorously it's quite addictive, no need to bury the pedal for brisk acceleration.

At the time of buying the car i had no diagnostic equipment so couldn't read any codes or reset or evaluate any history of error codes, so have no idea if codes would return or not and at what intervals.We only ever experienced the engine light on, no flashing on hard acceleration that i've read elsewhere suggesting more deep seated problems within the system. The car did have a quite an induction roar, to me anyway, on light to medium acceleration which completely went after the fix. Obviously i've read about the lower intake manifold problems so rather than have it cleaned, as many do, i took the belt and braces approach of buying new figuring whilst in there it makes sense. This sorted the problem for us along with low misfire count on one injector it too replaced for new. I'm keeping my thoughts quiet on the fsi potential problems for now but will pm you later about it.

WOW

So you replaced both the full lower inlet manifold (flap, actuator and potentiometer) with a new one and then a new injector. Including labour that must have been a very pretty penny indeed!
