VW Transporter T5, 2005, 2,5 l turbodiesel, automatic transmission. VW Eurovan
Dense white smoke often indicates coolant in the exhaust. Check for water in the crankcase by inspecting oil on dipstick. Milky coloring indicates water. Check the coolant reservoir, or under radiator cap (wait until engine is cooled down!), for oil in cooling system. If you see evidence of either water in oil or oil in coolant, you may have a blown head gasket, or a cracked cylinder head or block.
Testimonial: "Thank you very much for your answer! No, everything seems fine. By the way; I have no error lamps or error codes."
Update: Broken turbo and defective N75 valve. Replaced, cleaned up all the oil on the air side of the turbo, removed a lot of oil from the intercooler. Then everything was finally okay.

Take it to a workshop to check if head is not cracked the T5 s 2.5 have a problem with cylinder heads cracking where injectors seats
Testimonial: "Thank you! The problem was due to a turbo brake-down. Replaced turbocharger, cleaned up all the oil on the air side of the turbo, removed a lot of oil from the intercooler. The N75 valve needed to be replaced. Everything finally okay."

SOURCE: Transmission problem
If the S light is blinking, this indicates that there is an electrical problem somewhere it the TCM circuit. I have included a link that takes you to an excellent page which shows you how to read the codes and what they mean.

Also, The top solenoids are for the lockup clutch and the bottom ones are the shift solenoids.
As for the Immobilizer causing problems, if it was incorrectly wired to the TCM, then it could possibly cause a problem.
SOURCE: can't pass 3000 rpm
need to check codes and see if it has oil in it. and go from here.
if the computer sences low oil pressure it sets a rev limiter to try and save the engine. code P1259 i think. 4 or 6 cyl?

You have 2 solutions, either to get the TCU referbished/ repaired
or totally change the transmission system. I did the second one.
SOURCE: 05 Golf TDI sudden loss of power. Turbo issue?
ecu problem! go and find someone with VAG-COM and get it checked for fault codes. glad i could help!
SOURCE: 2000 TDI - Lots of white smoke at cold start.
Sounds like your injection pump timing is off, an injector is leaking or a bad seal on your IP.
VW dealers have a horrible reputation when it comes to TDI's. Check out the posts over at www.tdiclub.com Those guys are very knowledgeable - and the first thing they'll tell you is don't take it to a dealer.
You can probably find someone in your area that has a copy of Vag-Com (scantool software that vw uses) software that could look at your timing. It definitely sounds like your dealer was throwing parts at your car because they didn't know what your problem is. If I were you, I'd copy and paste your post from here over at www.tdiclub.com
