New turbo/ underboost/cruise control
Just fitted a new turbo but it seems whenever I use cruise control I get a turbo underboost fault P0299. Any ideas anyone please ? I do have a recurring EGR insufficient flow fault if that could be anything to do with it.
Thanks.
Thanks.

Re: New turbo/ underboost/cruise control
Fault 2099:
Description: Turbocharger pressure signal - Pressure too low in relation to the reference value. Difference negative for 5 seconds, between the turbo pressure reference and the measured turbo pressure. The pressure measured is lower than the reference, around 300 mbars for an engine speed above 2500 rpm.
Fault will be triggered:

Re: New turbo/ underboost/cruise control
Assuming this is the 1.6 Hdi in your profile and just guessing that it has the same engine as my old C5 X7
Have a look at Devil Car
Turbo solenoid valve, cheap as chips but depending on location within the 1.6 engine bay is a mare to get to but caused me no end of aggro but worth a look at

Re: New turbo/ underboost/cruise control
Thanks Marc, I have noticed when fitting the new turbo that there doesn’t seem to be as much clearance between the new oil feed pipe and the actuator rod as there was on the original turbo. I bought a replacement pipe to go with the new turbo.GiveMeABreak wrote: ↑14 Nov 2019, 15:31 Fault 2099:

Re: New turbo/ underboost/cruise control
Have you got the correct procedure for removing / fitting? It's a bit involved and there is a specific procedure you need to follow after connecting everything up before starting the engine? If you want me to post it up let me know . There may be something in there that you haven't followed...
Plus - did you fit the new banjo bolt with the revised filter / strainer? This was also a modification as the old type can clog and starve the turbo of oil.

Re: New turbo/ underboost/cruise control
Was fitted by a mechanic friend so I assume it was done correctly , however I did notice that he didn’t use one of the very small paper gaskets supplied with the turbo (not sure what it was for). I’ve alsi just noticed that there is a small oil leak (leaking at or onto the top of the actuator). No didn’t fit new banjo but old one was thoroughly cleaned out .

Re: New turbo/ underboost/cruise control
I have a bit of time, so will put it up anyway:
Removing / Refitting Turbocharger - C4 Picasso 1.6 HDi 110 FAP (DV6TED4)
Removing
Remove:
Checks:
Examine the engine air filtering system.
Check:
Check that the oil circuit unions are clean.
Note: Use the recommended bolts and nuts (heat resistant).
Replace:
Cautions:
Refit the catalytic converter and particle filter assembly.
Refit:
Precautions to be taken before starting the vehicle
Removing / Refitting Turbocharger - C4 Picasso 1.6 HDi 110 FAP (DV6TED4)
Removing
- Disconnect the battery.
- Remove the engine style cover.
- Protect the engine cooling radiator to prevent damage to the fins.
- Plug the turbocharger inlet and outlet openings.
Remove:
- The air inlet sleeve from the turbocompressor
- The turbocharger noise attenuator
Remove:
| Note: Keep the filling cylinder full. Uncouple the lubrication return pipe (5) ( as "b"). Note: When slackening the unions, ensure that they do not rotate (Support them if necessary) Remove the lubrication pipe (6), allen screws (4) and ring seals assembly. |
Note: Check there is no strainer present at "c" on the bolt (4b). Remove (If necessary) by means of a screwdriver. | Remove:
|
Remove:
|
Examine the engine air filtering system.
Check:
- The air hoses
- The condition and the correct positioning of the turbocharger vacuum pipe.
- Induction circuit
- Exhaust gas manifold (it may cause the destruction of the turbocharger when operating it)
Check that the oil circuit unions are clean.
Note: Use the recommended bolts and nuts (heat resistant).
Replace:
- The turbocharger mounting nuts
- The turbocharger lubrication banjo bolt copper seals
- The catalytic converter clips
Cautions:
- At refitting, all the removed seals must be replaced with new seals.
- When refitting : Remove the blanking pieces on the turbocharger at the last moment.
Replace the seals "d" and "e" of the turbocharger. |
Cautions: Clean the gasket faces with an approved descaling product. Do not use abrasives or sharp tools on the joint faces. The gasket faces must not have any traces of knocks or scores. Pre-fit the components of the turbocharger, in order to adjust their position (Before final tightening). Always replace: The nuts (8), (10) and the bolt (7). Couple the turbocharger to the exhaust manifold. Fix:
Tighten:
Couple up:
|
Method for tightening the upper union: Put a ("A" = 8,5 mm) diameter pin in place vertically, as indicated above Tighten the bolt (4a) supporting the union using the pin; Tighten to 3 ± 0,45 daN.m | Method for tightening the lower union: Put a ("B" = 7,5 mm) diameter pin in place horizontally, as indicated above Tighten the bolt (4b) supporting the union using the pin; Tighten to 3 ± 0,45 daN.m |
"C" Incorrect fitting of the lubrication pipe. "D" Correct fitting of the lubrication pipe . "F" Authorised angle of movement: 3° (0; +0,2). CAUTION: Placing the lubrication pipe under stress will result in engine oil leaks; After tightening the unions, check that the lubrication pipe moves freely; Otherwise, repeat the unions tightening operation and replace the seals. Couple up: The vacuum pipe (6) ( as "a"). CAUTION: Carry out a pre-fitting to adjust the position of the catalytic converter and particle filter assembly. |
Refit:
- The heat shield (2)
- The bolts (1)
- The turbocharger noise attenuator
- The air inlet sleeve from the turbocompressor
Tighten:
|
- Disconnect the connector of the diesel injectors.
- Turn the engine over with the starter motor for 15 seconds.
- Reconnect: The diesel injector connectors.
- Let the engine run at idle for 30 seconds before increasing the load.
- After switching on, check the sealing of the various unions.
- Clear the faults in the memory, using the diagnostic equipment.

Re: New turbo/ underboost/cruise control
Thanks yet again Marc, your knowledge of these beasts is amazing.
Please could you also tell me the part number for a replacement EGR valve, may aswell change that too, if only to eliminate it. Thanks.

Re: New turbo/ underboost/cruise control
Hello Marc
I am to take a turbo from an old c5 to put into my current c5, I'm going to get organised and gather up a few bits and pieces needed for the operation and try to get at it maybe next month, i will remove the turbo from my old car myself and give to a proper mechanic to fit.
Can I ask you about a few things on this.
What all new parts would you recommend i need? (seals,nuts bolts and gaskets? Would you have part numbers for each or where can i order from - could i order from a Peugeot garage because there is one close to where i live?)

Re: New turbo/ underboost/cruise control
One more thing, would it be advisable when I'm at it to take the dpf from old car, and get it cleaned and then put it into current car?
What's the removal procedure like?
Anybody any experience of getting DPF cleaned? Any good?

Re: New turbo/ underboost/cruise control
It won’t hurt to have a spare or swap them as you’ll be working around there anyway. But if you do this, remember to tell the engine ECU you have replaced the DPF under the repair menu, so it know this.

Re: New turbo/ underboost/cruise control
Any chance you have a removal proceudre for the DPF please, and can the whole unit be removed in one peice rather than just taking out the insides of the unit?GiveMeABreak wrote: ↑23 Feb 2021, 09:58 Ok, so these are the recommended parts to be replaced according to the procedure.
