Removing or cleaning the EGR system and intake manifold on VW TDI or Audi TDI If there is excessive carbon buildup on the intake manifold and EGR, it must be removed and cleaned. There is no set time, mileage, or factory recommendation on when to clean it since accumulation can vary according to type of engine oil used, driving style, quality ...

2015年5月4日 · Yeah, got the partsno. for vag plates 038 131 925 and gaskets 028 131 547, so will just buy them directly from my vw dealer. I've had a read on the egr wiki here, but the thing is the mk6 has the egr mounted in a rough spot, so would be great to get some photos from a mk6 to see what I'm dealing with in detail.

2014年4月29日 · The EGR cooler could leak coolant and go back into the intake through the EGR. Remove the intercooler and pressure test it underwater. Only other place coolant sees intake is the EGR cooler. Also, since you already have what looks like clean green coolant in there, don't mix it with pink VW coolant. It'll sludge and turn brown.

2015年10月10日 · They reduce the flow enough to improve low rpm pickup but not so much to make the ecu detect the egr as disabled (in the mk4 and mk5 ex. CR, the ecu reads the egr indirectly by expecting a decrease in the maf flow, as the recirculated exhaust will take the place of some of the fresh air, the maf readings will drop).

2015年9月3日 · For your 2005 Jetta...dump the EGR if your local inspection does not check. The VW system components are expensive and have very low reliability. The Dynamic tune does not rid you of these problems. The only benefit (if any) doing Dynamic over delete is that removing it requires another couple of miles driving for the engine to come up to full ...

2010年1月21日 · The difference between the 2009 and 2010 4 cylinder TDIs and earlier ones is the complex EGR and exhaust treatment system. Every once in a while, the diesel particulate filter does an active regen cycle by injecting fuel after the main combustion, which heats up the DPF and burns up accumulated soot.

2014年2月1日 · Exhaust Gas Recirculation (EGR) flow malfunction could be caused by a clogged Exhaust Gas Recirculation (EGR) valve or Exhaust Gas Recirculation (EGR) tube. Before replacing any parts try cleaning the Exhaust Gas Recirculation (EGR) valve, tube and passages. When is the code detected?: Low Exhaust Gas Recirculation (EGR) flow control is detected.

2023年2月26日 · Hi all, I replaced the DPF and EGR filter a couple of weeks ago in my 2011 Jetta TDI and shortly thereafter starting receiving a P0471 code concerning the sensor (directly behind the oil fill cap). I replaced that this weekend and idles and runs fine but …

2024年10月27日 · Any idea on good method for clearing the intake manifold runners of, at the lowest point, a 1/4” of nasty carbon buildup? Also interested in a viable method for egr bypass without triggering limp mode if possible. I’m sending the ecu out to programming for a manual swap soon, should I ask while it’s there about egr deletes?

Remove the single torx screw holding the turbo inlet adapter in place and rotate the black plastic adapter towards the firewall to remove. Remove the 3x T30 torx bolts holding the low pressure EGR tube and the 2x T30 holding the turbo outlet adapter (VW calls this a noise dampener).
