Hi
Bought this 2007 reg car privately last month. Everything seemed fine when I bought it except very low engine oil.

Few weeks later the car stalled randomly and then the engine light came on 10 mins later.

Took it to a garage. The error was to do with the turbo signal or something and they replaced the unit. A week later I stalled accidentally and then the engine light came on again about 10 mins later. Just took it to the garage again and they've rang me back saying the turbo sensor or something had oil on it. And that basically this will probably keep happening. And my engine oil will keep leaking as well. Also because of this the turbo won't work properly.

Does anyone else here know anything about similar problems and solutions?

PS. Acceleration from stop is very slow. It also has trouble accelerating at higher speeds. I'm sometimes in 4th gear until 60mph. Never drove a diesel before so not sure if this is normal?

Acceleration will be slow when the engine light is on.
You need to get a diagnostic from a garage that has Fiat experience or specialist.
1.9jtd should be quick, lots of torque.
What was the part they have actually fitted.?
Where did they suggest the oil was coming from.?
How many miles has the car done.?
If the oil they found was in the vacuum pipe to the turbo solenoid then my thoughts are that the oil could be getting in to the vacuum lines from the brake servo pump.

Sorry for the long delay in response. Thanks for replying

The engine management codes the first time I put the car in were
P0235 - Boost Pressure Sensor
P0095 - Air Temperature Sensor (Inside Supercharger Sensor)

So the part they replaced was the MAP (Manifold Absolute Pressure) sensor bosch.

A week later the light came on again and when I took it back to the garage the code was:
P0238 - Turbo Pressure

The guys said that one of the parts (can't remember which; I think the MAP) was getting soaked in oil. Don't know where from. I'll try and ask them this week.

The mileage on the car is almost 100k.

I'll probably have to take it to a specialist. There's only around central Manchester (Arnold Clark Fiat in Salford). But before I do, does anyone else have any ideas?

A few things that need checking :
Turbo boost pipes for splits.
Turbo impeller for excessive play and oil.
Wastgate operation. (Not seized)
If the turbo is vgt then check for sticking vanes.
Check the vacuum pipes condition to turbo boost control solenoid. Check for oil inside the vacuum pipes.
Check EGR valve ( clean out or blank off)
Check the inlet manifold swirl flap function. (The operating rod can come when worn or seized)

Any updates on this? I'm also getting code P0238.

Hi
I took the car to another garage in December and haven't had problems since.
He fixed up some loose/misplaced pipes and such.
Apparently the engine in the car may not have been the original engine and may have been put in by some cowboys.

Dirty EGR valve??
Notorious problems on the 1.9 multyjet

From what he told me, everything was dirty.

Of I was u I'd take of the EGR valve and give it a dam good clean.. cause it sounds like that it causing half your problems.. boost.. power.. dip in power etc.. all are down to the egr valve

I diagnosed my problem as sticking turbo veins. I sprayed a can of Wynn's Turbo Cleaner into the turbo and it transformed the car. It could be worth a try at only £13 a can?

Can you tell me exactly how u did this with the spray.?
I had the turbo boost error aswell.. but I plugged in the old machine and just cleared the fault codes. But it just don't feel right when I'm driving "turbo holding back on me"... the old sod

1) Remove the battery and battery tray.
2) Remove the bolt holding the top of the air box on.
3) Remove the turbo inlet pipe (if you can, optional), remove the MAF.
4) Jack the car up and Remove the passenger side front wheel. Remove the engine underside trays.
5) Undo the two bottom bolts for the airbox (if you are careful you can just lift the box over the bolts to save removing them.
6) Follow the instructions on the Turbo Cleaner as you are now able to spray it directly into the turbo.
7) Wear a mask as what comes out of your exhaust afterwards is terrible!
