Hi,
I recently serviced a 2011 Leon 1.6 diesel and a week later, whilst on open road driving, the owner reports a massive loss of power, with EML light/glow light coming on instantly. I won't be able to pop onto diag until tomorrow evening, but is there any common fault that could cause this? Had a scope about this forum, but got no joy, or maybe I just missed it. Any help appreciated.
