Yep, had the Tiguan in to our VW specialist for snows and a check engine light and he diagnosed a failed intake manifold. Again.

This will be #4 intake manifold for our 2010 Tiguan (150,000 km) and we are not amused. Original I.M. nuked itself in September 2013, replacement failed in September 2014 and now this, just over 1 year later.

Called the dealer who noted it was 22 days out of warranty(!) but they might be able to do something special for us. Luckily, I still have a letter from VW dated August 2013 extending our intake manifold and fuel injector warranty for 10 years or 193,000 km "under special conditions".

I will report back on "special conditions" decision.

How many times have they had to clean the valves (carbon buildup)?

They should cover the repairs for the life of the vehicle. It's their faulty design that is causing the failure.

the consumer shouldn't have to pay for their mistakes.

OK, spent 3 hours with the dealer today and they diagnosed the fault as (wait) a malfunctioning intake manifold. However, since I already had it replaced under warranty (last year) I can't have it replaced under warranty again. Because I already did......... Get it?

Chat with service manager pointing out that this will be our 4th IM in 5 years, that a recall notice is out on the part, and that the warranty for the IM and the injectors was extended to 193,000 km and 10 years. Deep thought, a call to regional HQ and voila, they will replace the unit but under "goodwill" not "warranty". Somehow it was important for me to see the distinction.

And yes, we paid $120 (I think) to get the carbon cleaned last replacement.

120 bucks for that manual service sounds too cheap. Are you sure they didn't just run some solvent in there for that price?

Maybe next year they'll replace it under "good will". Our do they only give you one of those?

Not sure I’m posting correctly but my 2012 Tiguan has the same issue. I took it in for the 70K service and they broke the news! My mechanic simply said “buy Japanese!” I’m going back to Toyota!
I’m in the US in California to be exact, what did this cost you? My mechanic directed me to the dealer.

It's a known problem for any VW with the 2.0L engine, I talked with the VW tech that was working on my CC, there is an electric motor that fails it's part of the intake manifold that's a non serviceable part. There are little flaps inside the manifold that's supposed to get the incoming air flow into the cylinder head to flow better, well it doesn't, it just makes the vehicle run like some left a shop rag in the intake. When they put the the system to sleep so I could drive it, it ran like a rocket. The black gummy crud is from the PCV system it mixes with some of the gas spray from the injectors that burns on the back of the intake valves, This part of the German Engineering Klaus or Hans designed isn't worth a crap. Use a good quality fuel and Injector cleaner to keep the debris off the intake valves.
