    I'm in the same EGR cooler P2002 struggle. Did you manage you find a how to guide? That cooler is buried behind the DPF and under the turbo.

    I couldn't manage to change it, so gave it to a local mechanic that specializes in german cars here in Limerick. He managed to get a second hand throttle body & told me he cleaned the EGR valve located beside the throttle body (~€300). Gave it back but there was still something wrong - no low end power. Eventually after a week, more lights came on.... finally replaced the EGR valve and its running all fine again (~€500). Hope this helps!

    You guys are lucky...at least someone is willing to do it. There are several garages where I live. There aren't that many VAG specialist garages, the ones that are seem to charge almost dealer-like prices. I saw a video on the internet a few weeks ago where the guy took the DPF off to get to the EGR. It's no tutorial but it gives you an idea of what you have to do. He took the whole front end off! If I had a week off work maybe I could have a shot at it but it's a big job regardless. One guy told me that he has to take the subframe off to get to it from underneath . Then when I told him to go ahead and do it, he said he didn't have the "manpower" to do it as it needed a second pair of hands.

    However, there doesn't seem to be any issues with mine at the moment. The DPF light comes on every other week though. I've been told that it's probably at end of life seeing as it's been on the car for 165k miles. After a short blast on the motorway at 3k rpm, it soon goes.

    I removed mine today and letting it soak tonight. I'll refit it tomorrow. 3 hours to get it out. No need for a ramp you can do everything from the top once you remove the bulkhead just behind the engine. Alot of pipes and brackets to remove and a few tricky bolts but doable.
    I removed the DPF while I was at it and that's gone for a full clean as VCDS said it was 3/4 of the way to max ash limit . Cars on 136k miles
