I've looked on the workshop manual with no joy ,and Haynes doesn't mention it, but I suspect I've lost a part of the fixing at the rear of the lower section of the air filter assembly  as I've now got a nasty rattle from the air filter box .

With the problems from starter I decided ( at long last ) to check out the trigger wire , and when changing the battery I took the chance to take out the battery tray, which means removing the air filter assembly .

As said I can't find any diagram on the workshop manual , so any picture /link to a diagram would be welcome. If as I suspect there's a second fillet etc which fits on the peg ,is this assembly similar to the polo ,and if so anyone got a part number. ( I've got the luxury of both a Skoda and VW dealer close to me . The VW place is as helpful as the Skoda place is unhelpful, but the VW stores lad needs parts numbers).

Looking at the rear of the assembly ,I'd suggest that it's designed to have a plastic insert slide in and attatch to a  peg on the  bodywork, with a soft rubber washer.

TIA .

 

AMF engine?

Again thanks, Lee- I couldn't find this diagram, but from a look at rear of filter assemble thought that there should be an additional bit between item 18 /26 and the lower body. The good news I got was that the "trigger" wire to the solenoid looks OK( but to my mind the gauge of the wire looks a bit small to carry the sort of current I'd expect on the trigger . ) , and possibly ( at moment) the problems I've had with what I thought was a sticky solenoid was down to not just an ageing ,but geriatric ( 9 year old )  battery. Extra good news from the diagram is that I haven't had any bits disappear into the black hole under the engine. All I've go to do is ( from the diagram ) fit item 18 into the lower body.
