Hi, water leak from seam in firewall just behind brake pedal, fed a 10 foot cable in the gap to see where it came out below car or in engine bay , no luck, anyone any ideas on where the water is coming from and how to plug it from the outside, it is not water getting by the doors or leaking from the heater, scuttle is clear of debris and drainage holes are clear, liners were taken off last year and silt was removed, I don’t want to seal it from the inside of the car, thanks in advance, Conor, 2003 mk 1 Octavia 1.4 16v, 292000 miles, still going strong.

Hi Conor,

As you look into the engine bay, each side should be a small grommet if it's there, down by the bonnet hinges.

From my old L&K.

Every time it rained, my carpet was soaked, and it ended up ruining the underlay.

I had to rip everything out to try and dry the interior.

Under the scuttle panel, to the right of the cabin filter, I had this grommet missing. This was for left hand drive cars who had the bonnet latch wire coming through the firewall. UK cars have it on the right.

Purchase a load of bungs/grommets and sealed it over.

Never had a leak again.

Thanks very much for that detailed reply, I will have a look at sorting that out on Friday, really appreciate it, Conor
