We designed an engine bay panel cover for the VW MK4 in CAD - and had to make two versions because of the washer tank
Been working on an engine bay panel cover for the MK4 platform - Golf, Jetta, Bora, R32, all of them. Designed it in CAD, made it from 4mm ABS plastic, bolt-on with a bracket included.
Sounds simple, until we realized the MK4 came with two different washer fluid tank sizes depending on the market:
- 3L tank — North American spec (US/Canada)
- 5.5L tank — European spec
The tanks sit in different positions and take up different space, so one panel design doesn't fit both. We ended up modeling two separate versions to make sure the fitment is clean on each.
Works across all MK4 engines - 1.6, 1.8T, TDI, VR6, R32. No cutting, no modifications, just bolts in.
If you're not sure which tank you have — check the size printed on the reservoir itself, or just look at how much space it takes up in the bay. Happy to help figure it out if you drop your market/year in the comments 👇
