Hi All, looks like I've just joined this exclusive "check vsc", engine management & traction/esp warning light club, with a dodgy temperature reading thrown in.
is220d, 2007, 70Kmiles - largely urban mileage in recent years, wifeys car, I've just started using it on my 90 mile round trip to work to keep the escalating mileage on my car down
1 week ago, check vsc, engine & traction control lights came on on motorway. pulled in shortly after as I noted the temp had entered the red! a quick phone assisted google and wife relayed the story of same warning attended by AA, advice was run it a 3000rpm. Did this, temp dropped and when I got home and restarted it, the warnings had cleared. (I knew the temp warning was phoney, as restarting the car 2 mins after stopping the temp reading was normal(ish) so quicker than the block would cool.)
2 days normality followed.
Then it re-occurred on my 90 mile round trip to work. got home and borrowed a reader.
OBD codes read and cleared
P0400 Exhaust Gas Recalculation Flow
P0117 Engine Coolant Temperature Circuit Low Input
(above according to google)
After clearing the car was fine for a few weekend urban short trips.
Back on the motorway this morning and returned.
Interested in your thoughts and feedback.
thinking at the moment would be to decoke the EGR (as per the video on page 1) and add some Diesel Fuel system cleaner to the mix....
