Volkswagen Golf IV - Vw golf mk4 engine warning light - kinger5542

Hi,

Got a very frustrating problem with my 54 plate golf tdi. It seems when it rains the engine warning light comes on and will not go off until the fault gets deleted. I am assuming there is a fault there as my mate used to work for vw for 6 years so he borrowed the 1552 from vw, plugged it it in but there was no fault found at all. so he goes through the process of deleting the codes (even though the 1552 didnt pick any up) and low and behold, the light goes out until it rains the next time and it will come on again!

It may just be very coincedental but it has happened 4 times and it has always been wet!

Also i have water leaking (slightly) from the passenger footwell from right behind the glove box. The inside of the glove box is dry. I can also not feel anything when i put my hand up behind the dash, it seems completely dry but every now and again you can see a few dribbles of water sliding down the mat in the passenger footwell.

ANy help with this would be very much appreciated.

Thanks, Matt

Take the bulb out, then just before you sell it put it back in again and get your mate to reset it again.

Probably a badly sealed pollen filter (just behind the glove box!)

Also check that the plenum drains aren't blocked

Water + car electrics dont mix.............

thanks for the reply. I have checked the pollen filter and it is completely dry inside and out. where are the plenum drains? are they at the side of that plastic thing at the bottom of the windscreen? I have also taken both door cards off and they are completely dry inside. i have noticed there was a little bit of water on the mat in the rear passenger side footwell!

thanks, matt
