VW Transporter Misfire Points to Intake Manifold Issue

As someone with decent experience working on VWs, I had a very similar issue with my 2003 VW Caravelle diesel. The symptoms you describe match exactly what I experienced, rough idle, engine performance issues and that distinct exhaust smell. After checking for vacuum leaks myself, I took it to my regular workshop where they diagnosed a scorched intake manifold. The air intake system was compromised, causing irregular fuel mixture and triggering the check engine light. The complete repair including parts and labor came to 1180€. The key symptoms that pointed to the manifold issue were: Rough idle and stalling, Drop in power during acceleration, Strong exhaust odors, Check engine light activation, Poor engine performance overall Before suggesting more specific advice, could you share: Current mileage on your Transporter, Any recent repairs or maintenance, Whether you notice the issues more during cold starts, If you hear any whistling sounds from the engine bay This information would help determine if your case matches what I experienced and whether there might be related issues to check. A proper diagnosis is crucial here as manifold problems can sometimes be confused with other air intake system issues.

Thanks for the detailed feedback. My Transporter has 69450km on the clock and had its last major service about 2 months ago. The intake manifold issue you described matches my experience perfectly. While no whistling sounds are present, the check engine light and rough idle persist despite the recent maintenance. The gasket leak symptoms definitely align with what you encountered. A loss in power is most noticeable during acceleration, suggesting the air intake system needs inspection. Based on your repair cost details, I will budget around 1200€ for the potential manifold replacement. Did your repair also include sensor replacements or was it purely the manifold and gaskets?

Thanks for those extra details about your Transporter. With my Caravelle repair, the 1180€ covered not just the manifold and gaskets, but also included replacing two sensors that had been damaged by the vacuum leak. The workshop found the original sensors were giving false readings due to excessive heat exposure from the scorched manifold. The absence of whistling sounds in your case is actually helpful for diagnosis, it suggests the gasket leak might be less severe than what I experienced. However, the engine misfire symptoms combined with power loss during acceleration strongly indicate an air intake issue that needs addressing before it worsens. A tip from my experience: have them check the intake manifold pressure sensor while they are doing the repair. In my case, a faulty sensor was contributing to the engine performance issues and rough idle. The complete fix restored normal operation and eliminated that persistent check engine light. Also worth noting that after the repair, my fuel efficiency improved noticeably, something to look forward to once yours is fixed. The repair completely resolved all the symptoms, particularly that rough running and stalling at idle that was so concerning.

Thanks for breaking down your Caravelle repair experience. The mileage on my Transporter is relatively low at 69450km, which makes the engine misfire even more concerning. Its good to know the repair resolved your idle and stalling issues completely. The absence of whistling makes me hopeful the vacuum leak isnt too severe, but the poor acceleration and rough idle are definitely impacting daily use. The gasket leak symptoms match what you described exactly. Ill make sure they inspect those manifold sensors during the repair, its helpful to know false readings from heat damage could be contributing to the problem. At 1180€ for your complete fix including sensors, that gives me a solid budget figure to work with. Since the air intake issues seem nearly identical to what you experienced, Ill get it booked in next week. The potential fuel efficiency improvement after fixing the manifold will be a welcome bonus. Thanks again for sharing the specific details of your repair, its given me confidence about the likely cause and solution.
