Today I was having a quick look for something in my engine bay when I noticed some oil on the oil filter housing and some surrounding bits. Looks like it has come from the anti shudder valve as depicted in green below.
The engine is a 2.0 TDI 170, BRD engine code. EGR was replaced May last year with a new Siemens part and the car was then serviced last June. At those times there was no oil at all. So it's happened in the last 11-ish months, and to be fair there is not a lot of oil.
Looks like only 100-150ml has been lost in that time. However if you look at the pictures below where I have circled in red it looks like a seal has "popped" out between 2 mating surfaces. That's where it looks like the oil has come from.
Is that how it's supposed to be? I have seen some used genuine ones on eBay that have the same thing, but new Siemens parts that don't have that.
I plan to clean it up and keep a close eye on it. Is it simply a worn seal or something more sinister?
Any thoughts on the matter welcome.
