Water in Secondary Air Pump

[PeterGAH]

I was having the Secondary Air pump changed to cure a Engine light and they found the removed pump was full of water.

I have poured some of this water into a glass jar and it has a brown sediment that settles out. The sediment is attracted to a magnet and smells of rust.

 

In this forum there is a thread dicussing this problem and it was caused by a "combi Valve"

 

I have asked both my usual repairers to change the combi valve and both say they don't know what I am talking about.

 

My question is simple. What is a combi valve called in Motor Trade speak or the skoda Parts Catalogue?

If you look on Rob Clubley's excellent guide, there are pictures of the combi valve:

Eventually after seeing engine light with code 16795 on a regualr basis and asking this forum I concluded it was the combi valve stuck.

I asked the dealer to change it but they didn't want to do it.

I decided to try EGR valve cleaner from Halfords

Used this product with a friend keeping the revs up while I suqirted it into the intake tract (Filter removed).

 

Result !!!  after some initial very strange running for 50 miles or so I have now not seen the fault code come up in the last 4000 miles

 

I would say that is a result

 

I think it was Wynns EGR cleaner or Halfords own
