Weird fan like noise from engine on 1.6 Blue HDi 16 plate

[kingy1912]

Hi All,

I have another problem with my berlingo not sure if it is part of the same problem i had with my DPF? Anyway i got the DPF replaced for a new citroen one 6 weeks ago and now i seem to be having turbo issues. Car is sluggish if loaded turbo seems to lag and not kick in properly till 1900 rpm and its using oil there is also a swishing noise from the turbo when driving it. This noise has always been present but was always very quite and hardly noticed now its noticeable when driving when the windows are closed and gets louder the faster i drive.

So since this has occurred i now have a noise coming off the car from the engine area at idle. If the car has just stopped there is no noise just usual from the engine but after 20/30 seconds of idling there is a noise like a fan is working becomes apparent. However the cooling fan is not switched on and the aircon is off plus no regeneration. Is there a hidden fan unit on this cooling something else out the road of is this something else??? If you rev the engine a we bit once it starts it also switches off and returns after a short period of idling. Not sure if its me being paranoid and its maybe been something there all the time and im just noticing it with the turbo issues. I most definitely think my turbo is on its way out so getting it in to the garage to see what the deal is with it. Any advice on this would be appreciated.

Thanks

Does sound like you have a turbo issue.
It’s quite easy to remove the air pipe off the turbo & check for visible damage or play in the bearings.

Hi Kingy, I hope you'll forgive a newby here for a really daft suggestion: Have you moved the roof bars to the acrossways position ? I fretted for ages over a fan/whistling noise which became increasingly obtrusive above 50mph, it even caused me to "take it easy" ! When I needed to return the bars to fore and aft the noise disappeared. Just a thought. T.H.

Just curious have you checked the turbo bearings yet like Lighty suggested?

What mileage does the vehicle have on it? What is the service history?

Keep us posted - good luck

Sorry but I don’t have roof bars

Hi Polar,

Thanks for replying. The car has 235K on it with an perfect service history. It gets serviced at a honda  dealership but using a service kit and parts sent from the groups Citroen dealership so it’s all Citroen parts and total ineos 0W30 engine oil used in it.

The garage checked the turbo compressor fan and it’s got movement in it. The intercooler is also full of oil so worn oil seals and/or bearing have been diagnosed. New turbo is now fitted but it has an actuator fault coming up on it. As soon as power is applied the car jumps in to limp mode. This is a strange occurrence since it was not entering limp mode previously or had any kind of lights or codes at all. Codes have been checked and nothing except the actuator code is present. Citroen have told them to do a full cool down on it and re do the steps for programming the ECU that it has been fitted with a new turbo to see if that works. If not Citroen have requested that it is then sent up to them??

Not sure if I’m better starting a new thread for the actuator issue?

Okay so the turbo hasnt failed prematurely neither has the dpf, sound like fair wear and tear. Sounds like the turbo caused the dpf failure?

If the actuator problem did not exist before the new turbo and dpf were fitted its down to the honda dealer to sort out - did they replace or clean the intercooler and inlet pipework?

One more thing if its a pre 2010 vehicle are are the injectors leaking, psa modified the injector clamps after 2010 ish due to them being a flimsy design that if torqued to the psa spect can leak - there is a theory by some people that the injectors leak and this causes the turbo failure.

I have a 2008 1.6hdi with the flimsy injector clamps and mine were very loose from the factory.

Hi again Polar,

Thanks for replying once again. The garage believes the turbo is just wear and tear they also believe the DPF going about that time was just coincidence as the DPF was throwing out a DPF worn code so they think it was just at the end of its viable working life. 

The old turbo was not throwing out any codes nor was there codes from any other area of the car. The system the garage is using is a delphi which was very recently updated because it was not reading the DPF worn code to begin with. It was sent away to be u[pdated and when it returned it was able to read the codes ok. So not sure if it might be a code that it is not picking up on but all they have to go on is the codes they can find.

The intercooler was full of oil so recommendation was to switch for a new one which they did and all the hoses have been cleaned out.

It is a 2016 Adblue model used as a taxi with 235K on it and as said before service history is bang on and well maintained.

I will post a screenshot of the codes they are getting but they think its either 1) faulty actuator on the new one not communicating right with the ECU 2) the actuator is not set correctly from the factory 3) the settings for the old one were changed at sometime thus throwing off the new one 4) faulty wiring or connectors or 5) there is other codes they cannot find causing a cascading issue.

All vacuum readings have been checked with the live date and all would appear to be within the ranges they should be. when they add vacuum to the actuator manually it appear by eye to move all the way out.

The codes it is throwing out if you can make sense of them are on the following shot attached to the post
