Battery yet again.

There are no drainage points around the tailgate - the black plastic liner takes most of the run off and the rest just slides down the metal underneath.

As you only had the vents re-sealed, I suspect that these are the culprits - silicone has a tendancy to lift off, especially in cold weather (snow!) and so instead of providing a seal, it will eventually attract water through capillary action!

oh dear... so I have to have the bumper off again?!?!

But what better way to seal them than with silicone? Or do I need to pay the £180 and have Audi do it?
 
And thinking about it Mike the car was bone dry since I had it fixed and this only became apparent again AFTER the snow we had!!! Darn. But surely you can't replace silicone every time it gets cold?!

Audi also said that the A2 has a huge draw from the battery every time you start the car. In a normal modern car you need to drive for half an hour to just put back what you took from the battery by starting. In an A2 they maintain you MUST drive at least 45 minutes. Hmmm. In 8 years of having this car it was never a problem before and now it is...

I think that you should take that with a huge pinch of salt! We have an A2 1.2tdi which has auto stop-start. After starting out for work in the morning, I usually have to stop at some traffic lights about 1/2 mile from home. Unless it is too cold, which de-activates the stop/start, the engine always stops at the traffic lights. If the battery needed charging the auto stop/start would not function. It is a 1.2tdi, not a 1.4tdi but any difference is not equivalent to that between a few minutes and 45.

No, spend around £25 on 2 new vents and then have them fitted for the price of an hours labour, or do it yourself if you have axel stands.

The new vents have a wierd sealant on them - it's like a foam rubber but it's very supple and resilient and seemingly, it's the only thing that does the job.

You could try some lead flashing stuff i got some from Ebay, its like silicone, comes in a tube but its alot better, i had a leak on a water feature in the garden and used silicone that just kept lifting so used this stuff works a treat now. i will see if i can find anymore on there and post a link

Cheers Phil

Just seen Mikes post or do what he said lol
 
Thing is Phil, whatever you do, you've got to remove the bumper, which is the biggest part of the job.

Whilst it's off, you might as well fit proper replacement vents.

Cheers,

Mike
 
Yes i think i was answering at the same time as you then when i looked you had put about fitting new vents so i added that bit on the end
 
Thanks guys. Audi quoted me £179 for two new vents and the fitting. Hence me taking it to someone else who did it all for £50 - but just resealing the existing vents and not replacing them.

I will do as you suggest Mike. I'll get the vents from Audi (Sadly no more Martyn at VAG Parts :-( ) and have the same guy fit them.

So the new vents will come with the correct sealant? OR do I need to supply them with this sealant as well?

The new vents have the sealing gasket already in place Johann - it's like a thick 'O' ring all around the vent and as you clip it into the bodywork, it just presses enough to provide a seal against the elements.

Mike
