Hi all

Fiat fiorino Van 1.3 Multijet Diesel mnfctr 2008 registered 2009 67000 miles on the clock.
There is no DPF on this Van.

On checking oil, level is rising considerably.(Fuel In Oil)
Have ordered Back Leak Off Tester (testing Fuel Injectors)

Whilst hooking up to Scanner the following errors displayed on Multiecuscan.


P0110-15- Air Temprature sensor(air flow meter) open Circuit/short circuit at +V batt Light ON


P0100-15- Air Flow Meter Open Circuit/short circuit at +V batt Light ON I


P0504 Brake Signal

P2264 water in fuel filter sensor

Check engine light is ON

If i clear errors they just return.


Are any of these errors associated with the rise in oil level?

Is the open circuit/short circuit to do with the MAF or the wiring to it.?

So far have cleaned MAF Sensor (may renew). Seems to have made no difference.

In spite of all the above vehicle starts ok,runs ok and pulls ok.

Any advice Please.

Is there actual oil in the fuel system, do you have bunch of smoke coming out of your tailpipe? Checked actual oil levels with dipstick?
 
If the oil level is rising then something (most likely fuel) is getting into the sump. My Fiorino has just been diagnosed with three over fueling injectors, they tell me the usual cause for multiple failures this is contaminated fuel. I had no fault codes but as you have one for water in fuel this may be the root cause which has caused one or more of your injectors to go faulty and unburned fuel is getting past the piston rings into the sump.

My van was running fine performance wise, I just had diesel knock between 1300 to 2000 rpm and slightly higher fuel consumption, then on the day it went in it started hesitating at 1300 rpm.

Thanks for reply Folks
The Fuel is in the oil but the odd thing is that the engine appears to be showing better than normal MPG
It pulls good and drives as if there is nothing wrong. However it does show on the ODB diagnostic that a new air flow meter may be required .

Whilst this confuses the issue somewhat i am loathe to try a leak back test on the injectors until i get the Air flow meter issue sorted .

The error reports that i should test wiring to meter first .

Currently down to 3 issues .
1 Activating high beam turns the headlamps off (so possibly earthing problem there)
2 airflow meter as mentioned

3 Fuel in oil (light blue smoke on starting only)


Always grateful for any advice.

I will post as to how i get on with this

Big thanks gromit.

Are all the lights going out when you put the high beam on, i.e. side lights and tail lights? It might be worth checking the headlight bulb, it’s a H4 dual filament type bulb, when you turn the high beam on the dipped beam filament goes out. If the high beam filament has blown then the bulb should in theory go out when the high beam is switched on. However I suppose it would be unusual for both sides to have blown so it’s a long shot but worth checking.
 
Hi Folks
UPDATE!
Having found the last fuse in the box had blown all errors have disapeared.
Lights, High beam now working correctly

No more water in fuel filter warning
Brake light switch error gone .
Most importantly i did not fork out £120.00 for new air flow meter .

So just fuel in oil now.


2 things that were very noticeable after new fuse fitted
.
Scan on odb showed-:
desired air intake was 100mg/L less than actual before new fuse after they were almost on a par give or take 30mg/L
EGR was 2% open However that jumped to 65% when new fuse went in.

Hope that helps someone Gromit

Glad you got to bottom of the electrics :)


Which fuse was it...wattage..?

Is the level still rising?
 
Hi


Fuse was last one in box down the full row of fuses

Its described as controlling the water in fuel amongst other things
It is 7.5 amp

The fuel in the oil is still a problem and i keep promising myself to do a leak back test on the injectors.

 The one thing thats bothering me (because i dont understand injector correction figure )
the injector correction figures show all injectors on 0 yes zero at 3000 revs and above whilst parked. i would dearly like to know if that,s normal.
