1- First of all, open the vacuum pump and clean its filter which tends to get clogged, then reassemble the vacuum pump. (essential step before accessing the turbo solenoid valve)
2- once the engine is running, disconnect the pipe connected to the turbo wastegate: check the change in position of the valve when removing the pipe and when replacing it.
3- still with the engine running, at the filter located at the end of the pipe (atmospheric air draw), insert an inflated transparent bag. Check when accelerating that the latter is empty of air.
If these two conditions are verified, then the solenoid valve is not faulty.
4- there is a circular filter inside the solenoid valve that it is advisable to clean.
Please is it the same on c4 Picasso 1.6hdi 110cv
Hello I have a problem with my c5 as soon as I accelerate the engine cuts out I restart I go up to about 2000 rpm and repeat and each time the same thing on the board it says it says pollution system defayan the fap is clean and I filled up with products what is it an orai an idea
Hello, I have a doubt about the operation of the turbo solenoid valve on my C5 1.6 hdi 110hp 2005 (c5 1 phase 2). Everything seems to be working, no loss of depression and proper operation of the turbo vane control valve at full load, the solenoid valve is clean, the small air filter is clean, the entire vacuum circuit has been checked and blown, no leaks, but despite everything when I "hit it" and exceed 3000 rpm the P0238 fault appears, switching to degraded mode and warning light on the panel. P0238 = too high boost pressure. Tested with the case (autcom delphi ds150e), I reach a pressure of 2495 mbars. So is it really a solenoid valve problem or something else? I don't know where to look anymore. The cleaning of the entire intake / disassembly and cleaning of the manifold and the supercharging hoses has been done. There is some improvement, but with the foot to the floor and more than 3000 rpm the fault returns. Thank you for your advice. Kind regards.
Your problem is the air temperature sensor which is clogged and not working properly.
Good morning,
Is there any learning to be done after replacing the solenoid valve (with the console)
