Over time plastic parts inside diverter valve become brittle and can easily break apart or disintegrate. I fixed those broken parts temporarily using super-glue and reinforced them with araldite epoxy resin (see HERE) while waiting for a new VAG diverter valve ordered frm eBay (@RM180+).
Today, when I opened up the diverter valve for inspection and I accidentally dropped it the whole plastic internal parts disintegrated!
Luckily I already got VAG diverter valve ready in stock.
Now, I simply transfer internal components from VAG diverter valve assembly into the stock diverter valve as shown below to complete the "downgrading"*.
(Note: many ppl fail to do this just b'cos they did not remove plastic ring adjacent to the yellow O-ring).
* I use the word "downgrading" because VAG internal parts are inferior (and cheaper) in comparison with the original components designed by Pierburg for EP6DT engines (Peugeots, Citroens and Coopers).
I'm driving 308thp 6 speed. I had an indication of "engine fault repair needed" today. I sent my car to a workshop and found out the same problem like yours. It costs me RM630 to replace it! Now I know the alternate solution...
