Before you reply, just note that if you're the type of person who replies something like get a different car, although your mum says she finds you hilarious, nobody else has to pretend to love you, so maybe go somewhere else.

I have the following 7 fault codes, and not being a mechanic, all I would like to know is:

1. What generally helpful but simple maintenance should I do (fuel treatment recommendations, for example) with these in mind?
2. What specific repair work should I expect a mechanic to recommend?
3. If you're knowledgeable about any of these particular codes, certainly share anything useful about the conditions that typically lead to them.

P0098 - Intake air temperature signal (intake air manifold)
- Short circuit to positive, open circuit, or value too high
- Permanent
P1351 - Preheating relay controlled and glow plugs not supplied
- Permanent
P2562 - Turbo position signal. Position too far from the reference value. No enough
turbocharging
- Permanent
P0490 - EGR, insufficient opening of the valve
- Permanent
P0495 - Controlled cooling fan function (integrated in the engine ECU); consistency
between the fan speed and the setting
- Intermittent
P0401 - Air mass meter, too high flow
- Permanent
P2563 - Turbo position signal. Position too far from the reference value. Turbocharging
too great
- Intermittent

Why have you posted the thread twice?
Did you use a generic reader or the Peugeot system as there can be a big difference?
Accidental, I just thought the first hadn't gone through. I'll work out how to delete that. The hardware is a TCS CDP Pro.

P0098 ,P0401...sometimes these are both in the Maf sensor(sometimes the ait sensor is seperate, a new maf could could cure both(10 mins job, 2 jubilee clips and a plug usually)About £28 of fleabay or 40 plus for better one.

P2562/P2563 both turbo faults could be related to vacuum pipes or solonoid that controls turbo, common problem area and easy o test with vacuum guage,

P1351 common fault , could be one or more glow plug gone or relay, easy to test both and guides available online to do it with meter .

P0490 common problem egr coking up, some blank it off depends which engine how easy to do, others swear by egr cleaner both relatilvely cheap to do

P0495 dont know

could be other reasons ,or cures but nothing there would bother me ,
just depends which engine you have and a diagnosis on pp would help

just saw your other post with attachment
the RHR engine is the 136 hp,, glowplugs on that engine are a nightmare of a job as down back of engine, egr is also hard to get to

Telling us your ACTUAL symptoms would be helpful too as a list of fault codes does not give the full picture.

lack of oomph hard to start smoking etc are also useful diagnostic codes :)

Point taken, thanks. The practical symptoms are:

1. Not always a perfect start first time, for which one or more dodgy glow plugs may be responsible.
2. An intermittent change in the rev pattern. It's fairly consistent that normal to quick acceleration is fine, but during slow acceleration or constant speed, especially in lower gears at lower speeds, there's sort of an on/off thing going on with the accelerator. It's more of an annoyance and probably less than ideal fuel economy than a significant performance issue.
3. I do notice that turbo doesn't kick in as early as I think it should.

Glow plugs do NOTHING for starting on your engine they are used to help regens not starting on all modern diesels.

low boost can be caused by vacuum loss as can the surging feeling due to the turbo not being controlled correctly.

Surging and poor starting may be because you have a bad injector another common issue on this engine.

Check your DPF settings too as the DPF getting clogged can affect the running too.

You probably have more than 1 real issue causing all the symptoms.
