Hi all, I have a problem that has developed on the wives 2009 A3 2.0 TDI CR that has done 113k. We had the glow plug light come on last week so took it to our normal Audi Specialist who said it was the EGR and that it was probably blocked. Instead of paying the £100+ for them to remove and clean it (plus they couldn't fit us in for a couple of weeks) I thought I'd have a go at it with my father in law. I bought the relevant gaskets and seals from Audi and set about it. Now I had seen a fair few guides and it seemed fairly simple. What I did fail to spot though were that most of these guides were for the older TDI engine and not the newer CR engine. We started undoing the bolts around the EGR and it was only when we were struggling that I looked in to it further and discovered I would need to remove the manifold also. Anyway we thought we'd give it a go still and to cut a long story short, 6 hours later we had removed it all, cleaned the EGR and put everything back together again. The actual EGR was mucky but nowhere near blocked however what I believe was the cooling valve on the side was completely encrusted in carbon and probably couldn't open hence the light. Anyway I nervously started it again and she kicked in straight away. I had a couple of warning lights (steering wheel one and ESP) but these went as soon as I pulled off. Apart from a tiny bit of coughing and spluttering on the initial start up the engine seemed to be running fine. However I took it for a short drive and as i put my foot down the engine makes a high pitched rattling/whooshing noise as it got above 2k rpm. It sounded like a permanently shaken maraca. To add to this the engine was reluctant to rev much past 2.5k rpm. Then as i took my foot off the accelerator there was a whooshing noise just like a dump valve on a boy racer car. However no warning lights! Does anyone have any ideas? My wife really needs the car as we have a 4 month baby but I'm wary of driving it. Thanks in advance!
