Technical Loss power Fiat Scudo 2.0

[Jimji]

Hi,
I have a Fiat Scudo Multijet 2.0 128 CV Diesel (2012) and since a few months my engine warning light and the warning light are on. When I drive, sometimes the car had a lose of power and it wants to stall. Those problems are momentously, like the lose of power, but it comes back. I don't think that is the turbo because is only momentaneous. The engine warning light disappears sometimes but it comes back. Hope someone can help me.

Does sound more electrical, can you get the error codes read to give more information?
Apart from that when it is in neutral ticking over try waggling any wires or connections to see if there is a break somewhere causing the problem.

I think that the problem is electrical. Indeed the car tells me to stop and repair the engine. I have also a small leak of oil. I want to know why the warning light turn off sometimes, why the problem is not continuous.
Thanks

Need to get the error codes read ideally.

Hi, sorry I didn't see the message, so this is the code error that the car shows "Engine problem: please repair the vehicle" (sorry it's in french). Also, those are the lights that turn it n when I have the problem, they are surrounded in white. Hope someone help me. Thanks for your time.

There should be some error codes that can be read via the diagnostic port, but possibly in the direction of the DPF and what it uses to clean it Eloys fluid or Adblue etc. low may be a starting point.
I had a 2012 Citroen that had those issues but with many more miles on the clock. It is possible for the fluid to run out early and cause DPF problems often due to people putting a small amopunt of fuel in many times , rather than getting low and filling completely as is advised. This is due to the computer adding the additive by the amount of time the fuel cap is opened and so running out prematurely.
A proper code read should be able to guide you.

Hello, thanks for answering my questions.

So I bought the diagnosis machine today, and the error code P0238, can someone explain me what does it means and how to solve it.

It translates to "boost sensor circuit A high " rather than too much boost pressure it can refer to a voltage that is too high due to a short circuit or a bad connection /corrosion and in fairness can be many different things.
So if no obvious corroded connections etc. you may end up trying to find a good diagnostic specialist, it is easy for you to end up chucking bucket loads of money at some so called professionals, so check carefully.

Hello,

So I've changed the throttle body, because the joint was damaged. The problem was a leak of oil and a low pressure, but now, when I changed it I have again the leak of oil and a high pressure , the error code is P0238.


Can you help me to solve it.

 

[bugsymike]

Do you mean the oil was leaking from the throttle body, as in getting into the air intake via either the engine breather or a worn turbo bearings?

 

[Jimji]

Yes, the oil leak is from the throttle body. I've already changed it, but it doesn't stop. And I have de same problem P0238. Thanks for your help.

It may be worth taking the intake pipe of the turbo and seeing if wear in spindle, it was one of the many things wrong on my 1.6 Doblo Multijet and cured the oil smoke by fitting a turbo cartridge. Check also not excessive oil coming from engine breather caused by either a blocked breather or engine wear.

I put 5,25 L of oil 5W40 , is this the appropriated oil, and the capacity?

My AutoData book only goes up to 2012, do any of these engine series tie in with your vehicle?
