159 Using Water & Oil...
My 159 JTDM 2.4, 125k miles, FSH, has started to consume 100ml and month, but more alarmingly 2 litres of coolant a week. I've had the cooling system pressure tested, no visable leaks, I fear the worst, any suggestions?
More diagnosis criteria, intermittent loss of power, turbo spools up ok and engine revs to 3200rpm no higher, but no power at all, lasts for approx. 1 minute max, then back to full power.
Could be Mass air flow meter sensor, Exhaust Gas Regeneration unit clogged?
It has rough idle at low revs coughing and jerking along if in traffic.
I had a dashboard fault show up recently “Anti-pollution filter clogged”!
No sign of mayonnaise.
Otherwise engine is just as powerful as always, except of course for the ever present turbo lag under 1500rpm.
Planning a 60 mile trip to see Lewis at Alfatecnico, when I can get time...
