silverb 0 Posted October 1, 2017 Hi everyone, I noticed a strong acidic smell from the exhaust, almost like ammonia, its unbearable when parked in the garage. any one any idea what this could be? its a 2011 2.0 Diesel, Just passed the NCT few days ago too. I had used some diptane last week, not sure if they are related. Quote Share this post Link to post Share on other sites
jimtaxi 3 Posted October 4, 2017 Noticed a strange smell just before the EGR valve failed in both my T25 2.2 D4D and T27 2.0 D4D it was more like a strong smelling paraffin. very strong when just parked after running. Quote Share this post Link to post Share on other sites
