I bought an immaculate 2011 outlander in April, no advisories on brand new MOT, late august got in to find wouldn’t start although turning over, tried jump start with no look as wouldn’t hold revs, had diagnostics which showed glow plug problem . Took to garage had diagnostics again they said new plugs plus modem, still wouldn’t hold revs, sent high pressure pump for diagnostics , tried also replacing this but still won’t hold revs.
Any ideas anyone, garage are baffled and car is still there
