Fiat Doblo 2005 Diesel MPV1.9 JTD Active.
Hi All,
Purchased early April to use as a runabout.
Solved a final problem ref Smoking Exhaust with a replacement MAF - now very clean running - considerable increase fuel economy - now circa 43 miles / gallon = 9.45 miles/ltre.
All was 'well with world' - ready for winter - then this morning - no start up.
MultiScan - shows Fault - Preheating Control Unit ( feedback) - 'low signal' - see Attachment Image 'NO START 1'
eLearn not showing much for that sort of thing.
Engine Started OK using squirt of EasyStart into Air Inlet System - first time I ever used - however product description states >>
"Warning: Diesel and petrol start must not be used for diesel engines with preheater" - 1st Question does the Doblo have preheater?
I have found images ref Heater Plugs and their placement on Doblo Engine - but as MultiScan states problem is a 'low signal' - see Attachment - can that be caused by Faulty Heater Plug/s or better to first look at wiring and connections?
Engine starts just fine now warm - just as always previously.
This morning was cold - but certainly previously colder mornings - however it was extremely wet/damp.
The Car has been a real 'winner' so far - especially since MAF incident - so wish to persevere.
Any advice more than welcome.
Best Rgds.
Steve
