Volkswagen Up! Exhaust System: Specs, Fitment & Common Faults
If your Up! is a diesel that had the Dieselgate emissions software update, this is worth understanding — a documented pattern links the fix to accelerated EGR failure afterward.

Volkswagen Up! Exhaust System: OEM Part Number
| Front pipe with catalytic converter (petrol) | Genuinely a different part from the diesel front pipe below — confirm your exact engine code before ordering, since petrol variants use several distinct references across the range |
|---|---|
| Front pipe with diesel particulate filter (diesel, where fitted) | A genuinely different assembly from the petrol cat pipe — combines the catalytic and particulate filtration function in one unit on most diesel engines, not sold as two separate parts |
| Centre/intermediate pipe | A genuinely separate section from both the front pipe and rear silencer, confirmed in VW Group's own workshop documentation as a distinct assembly |
| Rear silencer, front-wheel drive | VW Group's own workshop manuals confirm a genuinely different silencer and mounting arrangement for front-wheel-drive cars versus 4Motion — the underbody routing differs enough that the two aren't interchangeable |
| Rear silencer, 4Motion | A genuinely different silencer and mounting from the front-wheel-drive version above, to clear the rear differential and driveshaft routing |
| GTI rear silencer | A genuinely different, larger-bore system from the standard TSI, and on some versions includes an active valve that changes the exhaust note by driving mode — not a like-for-like swap with the standard rear silencer |
Worth Knowing: A Documented Link Between the Emissions Fix and EGR Wear
Worth understanding if you own a diesel VW that received the emissions compliance software update following the 2015 "Dieselgate" scandal: a documented pattern of owner reports links this update to accelerated EGR valve and DPF wear afterward. The technical explanation given is that the software fix increased how frequently and heavily the EGR system was used to reduce NOx emissions, which in turn increases the rate of diesel particulate matter produced, shortening the working life of the EGR valve, cooler, and DPF compared with before the update. Independent reporting has documented numerous cases of the EGR valve or cooler failing within a relatively short time of the update being applied — VW's response in a number of these cases has reportedly included replacing the EGR unit itself, sometimes at no cost, treating it as a related consequence of the fix.
Separately, and relevant regardless of whether the recall applies to your car: the EGR cooler on many 1.6 and 2.0 TDI engines is mounted at the rear of the engine, making it a genuinely difficult and expensive part to access — independent garages and forum reports consistently describe this as an unreliable component that can fail again within a few years even after replacement, with labour-heavy repair quotes commonly exceeding £1,000. A blocked DPF, meanwhile, is overwhelmingly a short-journey problem — the filter needs sustained running at roughly 2,000-2,500rpm for 20-30 minutes to regenerate properly, and a diesel used mainly for short, low-speed trips may never complete this cycle, leading to warning lights, reduced power, and eventually a blockage requiring active intervention.
Volkswagen Up! Exhaust System: The Part That Announces Its Own Problems
Where a lot of Volkswagen Up! parts fail silently until you spot something visually wrong, this one tends to make noise first — a rattle, a drone, an audible change that wasn't there recently. That's a useful early-warning system if you're paying attention.
Volkswagen Up! Exhaust System: What It Does
Away from the engine, through the silencer, and often through a catalytic converter and particulate filter before reaching the tailpipe — that's the Volkswagen Up!'s exhaust job in three steps. Petrol and diesel versions frequently need different systems entirely, since their emissions treatment isn't the same.
