Red engine light, fault codes, egr and electrical problem
Posted: Tue Feb 26, 2019 10:54 am
Qashqai 1.6 diesel ntec
Had dpf cleared out maybe a year ago (was 98%) as I was driving 100 miles a day on cheap diesel for two years, but I haven't done that for a year now.
So two things, my red engine light came on today, car seems absolutely fine, fault codes found include
Glow plugs heater circuit
Pre-heater unit (same thing?)
Dpf (although regen 100 miles ago)
Rail fuel pressure too low (was found at >4000 at 3mph?)
Egr valve?
Ascd function
The breakdown guy seems to think its the egr valve or the dpf? How easy is the egr valve to get to? Any advice? He also suggested low fuel pressure could either be fuel filter or linked to glow plug circuit problem.
He had no idea what the Ascd function fault was.
Will be doing oil and filter change tonight.
Second problem
It can take a while to start the engine first thing in the morning, more so if cold eg 20 second turnover and 2 attempts.
When I accelerate the power sometimes disappears, it's very intermittent, some trips it happens at every set of traffic lights etc, other trips it might happen once.
It's done this ever since I've had the car (>2 years) but seems to be getting slowly more frequent.
I figured it could be a faulty earth because I constantly get static shocks from the car, the lights/audio everything cut out when it happens but it immediately fixes itself.
Car also goes through more headlight bulbs than I've ever experienced in any other car (linked to power issue/potential dodgy earth?!)
Also also, car no longer tells me when to change up/down gear and no longer has the clock display next to the weather/temperature display.
any ideas appreciated as no one seems to be able to help.
