I have not been active on the forum for some time as I have been happily driving my 64 reg Qashqai Tekna AWD for over 5 years and 85000 miles.
The engine suddenly started with severe banging noise and loss of power. The banging just kept worsening quickly as we limped the short distance back.
My local mechanic, who is a friend was in the car when it happened.
There were no warning lights and all fluids were within normal range.
When we took the oil filler cap off smoke came out.
There were no faults when he plugged his analyser in.
He is pretty sure it is a piston that has gone but wants to take the sump off to check for metal to be sure.
The engine is the Renault built R9M 1.6 diesel which, up to now, has run well and been serviced at the recommended intervals.
I have not found anything similar on searching the forum and reviews appear to suggest it is a reliable engine.
Both of us are on holiday now so we will have to wait to be sure.
At least it didn't happen while on holiday.

What failed exactly? Did you experience any symptoms before engine failure? (change of engine sound etc.)
