I was working away yesterday putting bits on my new van and I was aware of a niff coming from the area nearby, a bit eau de shopdoorway on a Saturday night. It came and went and I looked for the source, expecting to find somebody had relieved themselves in my gateway, but no , the smell was not there. This smell came and went all day and it was a bit pervasive and annoying as I could not find the source.
It struck me later on the the smell of decomposing old urine was probably the Adblue (urea) in the engine compartment venting off as the temperature rose the hotter it got the more the smell. I checked to tank and it was tightish so it must come from the exhaust pipe as I could not figure anywhere else that it could be coming from. It would have been OK, but the area was sheltered with high fencing around it so it was a draught less suntrap. At least I know what to expect now. Phew!
