On this video I will show you how to diagnose a misfire on a 2009 VW Tiguan 2.0 turbo, these engines are well know for bad injectors, coils and carbon deposits on the intake pockets. So stay tune.

      Great vid! Question, you said when you first did the leak down test it came out ok, zero leak down. Then you cleaned the carbon and redid the leakdown, and you got high leakdown in one cylinder? Why would carbon cause the engine to show no leakdown? I would think it would be the opposite, carbon would cause HIGH leakdown, due to carbon holding the valves open, then when you clean the carbon the valves should seal better?

      james mack in most cases your assumption would be correct. But this time it was so much that actually was stopping the pressure to leak down

      Hello good evening,

      I have 2009 VW Tiguan. Brought it to the dealer to get serviced and to check up as EPC light came on and off about 6000 miles ago. Car drives fine no misfire but the dealer is saying that there is a low compress in cylinder 4. Dealer says it’s 7 bar/ 101 psi is this low? He said may be due to carbon build up or possibly damage. If it’s damage can it be fixed? Thanks for your help. Tom

      Tom Moran well if that is cranking compression is very low. They should have perform a leak down test as well to give you a more conclusive diagnostic! Carbon built it is most likely the root cause but there is still a chance of piston rings as well. What is the mileage of the vehicle? Have you keep oil changes as they should time and mileage wise? What type of oil you use?

      Ok, I got confused when you wrote glow parks instead of spark plugs! LOL
      So a misfire on a specific cylinder it should be easy to correct. Have you done a compression test and leak down test to see if problem is mechanical?
      Why did you replace the injector?
      You need to find what is causing the misfire, it is fuel or spark related, it is low compression on the cylinder or valves not sealing when cold?
      It might even be a Vacumm leak affecting that cylinder only, so as you can see I need a lot more info to be able to help you.

      Great video, very detailed with good quality

      We have tiguan 2012 turbo. Have epc and check engine and power off issue
      Dealer is saying oil spotted in cyl 4 and to dig further they say $1200 to check engine

      What are the causes to find oil in cylinder or may be its not oil at all and its a sinple change of intake system

      Appreciate your help

      Why did you say in this vehicle the relative compressor test is not good idea?

      about 1 year ago
    • Maic Salazar Diagnostics
      Maic Salazar Diagnostics In reply to david cisneros

      david cisneros not that is a bad idea, it is just that in this engine is super simple to remove coils and spark plugs to do a real compression test. A relative compression test is not the same but when you work on a V6 or so that half of the engine is buried then is the fastest way.

      phil holbrook you better buy a Maxysis Elite. It is way better than Snap on and can do programming too. Plus coverage and by directional options are amazing. You can get it for $3000
