OEM Part Number: confirm via VIN — tail light (aftermarket) Diederichs 2236091 / Alkar 2201138

Accuracy note: Covers the Volkswagen Up! (2011-) as listed in the UK aftermarket catalogues. Tail lights are handed (left and right are different parts) and the right one depends on whether your car has bulb or LED units, whether the cluster comes with its bulb holder, the body style and the facelift date. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives, and shown for the left-hand light with its right-hand pair where the catalogue names one. Carmakers rarely publish the genuine number against these, so order a genuine light against your VIN if you want a guaranteed match; if the unit on your car has a separate inner light on the tailgate, that is sold as its own part.

Confirmed: Why LED Tail Lights Fog Up More Than Old Bulb-Based Ones Ever Did — Volkswagen Up! Tail Lights

It's genuinely worth understanding why condensation in tail lights has become a more commonly reported complaint on modern cars than it used to be: LED tail lights simply don't produce anywhere near the heat that older incandescent bulbs did, meaning there's nothing inside the unit capable of evaporating moisture that finds its way in. Older filament bulbs ran hot enough to naturally dry out minor condensation on their own; LED units genuinely can't do this, so any moisture that gets in tends to linger considerably longer, particularly through autumn and winter. Light misting that clears on its own once the sun warms the unit is widely considered a normal characteristic of LED lighting rather than a fault — dealers commonly only consider a genuine fault confirmed when there's actual standing water or audible sloshing inside the unit, not simply a light misting on the inner lens.

A genuine, documented DIY fix worth trying if condensation persists: removing the light unit (typically a straightforward job of releasing the electrical connector and two retaining nuts) and using a hairdryer through the small access holes in the back of the unit can dry out trapped moisture directly, rather than waiting for sunlight to do it naturally. Before refitting, coating the foam gasket that seals the unit against the body with a thin layer of Vaseline helps it seat properly and can reduce the chance of the same moisture finding its way back in.

Volkswagen Up! Tail Lights: More Wiring Behind There Than Most People Assume

The Volkswagen Up!'s tail light unit typically bundles several functions into one housing — brake light, indicator, reversing light and rear fog light — which means a single electrical fault can affect more than one function at once, and a "faulty tail light" can mean several genuinely different things.

Volkswagen Up! Tail Lights: What It Does

Beyond basic rear visibility, tail light units on the Up! typically integrate brake lights, indicators, reversing lights and rear fog lights into a single housing. Higher trims may use LED units with a distinct light signature, which are not interchangeable with standard halogen units even if the physical mounting looks similar.

Tail light design changed between generations of the Up!, and facelifted versions within the same generation often use a revised light signature that isn't interchangeable with pre-facelift units. Always confirm the exact part for your specific model year before ordering. Whether you're sourcing a replacement tail lights for your Volkswagen Up! from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.
