Carbon buildup is rather normal, depends on the milage you put between cleaning. In regards EGR getting stuck- the mechanism for operating the valve is made out of plastic, hence some of the ''teeth'' within the valve guide gets broken/brittle due to excessive heat (your egr is circulating exaust gases after all) and with time the broken teeth causes the valve to get stuck. Make sure your coolant level is back to normal after changing the EGR, as EGR cooler runs on your engine coolant loop. Nice vid tho.

Brother, i have the v50 2009 2.0d. Because of this engine i can do most of the things by myself.. and with the help of your videos obviously. A real headache this engine. But actually it never let me down on the road actually.

Hi, the aftermarket is full of EGR valve manufacturers that have a different characteristic than the original EGR from the factory. Non-original parts cause pulsation of engine operation, increased fuel consumption and frequent DPF regeneration. In conclusion, any time the EGR valve is tampered with, it is necessary to perform an adaptation via diagnostics. If the adaptation is not performed the EGR may not function properly.

I had s40 with the same engine. It was a nightmare, when i remeber I have a headache. There was always something wrong with that car. You have good nerves, also your videos are very interesting and well produced.

What specific code you get? I have p1335 no matter what egr i put. After deleting it shows up again only after full stop engine and keys out. Can do start stop but leaving key in 1st position , no error then. This can i have is mental. Im so eager to find out what it causes
