I only use the oil that meets that vw standard. 500.1 or whatever it is. Its been amsoil and one other brand the auto stores sell but they meet spec. The problem came from a bad get sensor while on a trip. Sensor 1 failed and I believe it caused the car to run rich. Also couldn't get the vw to cover the faulty exhaust flap which I would think would hinder regeneration.
Yeah ............my point exactly.........that's why I state what I do.......You are not alone.....
I like my way verse taking items off and deleting them which is another method I am not fond of at all.
Did you know that when preforming Regen that more NOX is created at this time than when during normal driving?
It has to run at that sweet spot to run lean/hot.......... which is also why it weakens the exhaust and components life with more frequent Regens.
Seems counter productive to me and I believe that there should be evacuation ports to service a PTF system or ash sump.
There is no feasible reason to weld it all shut......... so it can have such ridiculous costs for a rat maze rubix cube.
In 2009 models CBEA they make you buy the CAT and PTF as a complete assembly.......seems fair.....NOT!
I would like to further point out that these problems with //CAT are 99% of the time related to blow by gases.
A quick review of gas engines 05> with these complex remediation's for the blow by gases is a complete failure.
Just look at the rate of PCV in TFSI and TSI or 5 cylinder stories.
These same methods with even additional components ( unmonitored OBD for functions still
) to convolute the diagnostic process in block or .
These valves and diaphragms fail no differently in the TDI and are the main cause for and sensor or CAT issues.
If you only treat the effect you get the same problem over and over again.
Lets start with a correction of the effect by fixing the problems.
Anyone can read the repair manual verbatim or its warnings.........I am not saying to ignore them....I am saying analyze them because they are not always correct.
Otherwise we are trapped in the box.........think outside it.....FREE YOUR MINDS cheers!
Don't jump off a building either.
