Many thanks

In fact I was referring to Chinese replicas and it has been one and a half years since I purchased it and my friend uses it in his garage and scanning average 5 vehicles daily basis. You won't have the agent specific functions such as shematic diagrams and access codes and latest updates for 308, 4007s etc, but to surive with a 406, that is more than enough I would say.

Hi all,

I just had the codes read.

He came up with;

1. Intermittent fault. Supply to sensors short circuit to earth
2. Intermittent fault accelerator pedal. signal to circuit to + or earth
3. Accelerator pedal to coherence with pedal signal
4. Intermittent diesel High pressure. Lack of pressure
5. Crank and camshaft syncopation signal speed to sudden
6. Heating circuit pre-heat

looks like its an earth problem ... where to start??? lol

also can someone please tell me how to solve or what 4-6 means?

Thanks

6. Heating circuit pre-heat

This is possibly faulty glow plugs - If they need replacing don't go to Halfords - They are useless

Good luck

Thanks mate, Where would eryone else go? I normally get my parts from euoparts?

Dose anyone know about 4 & 5?

Got my Glow Plugs from EuroCarParts. Touch wood they have been ok

Paul.

Thanks mate, guess I will be making a trip to europarts.

Can anyone please tell me which area to look for a problem relating to "4. Intermittent diesel High pressure. Lack of pressure".

Many thanks

Hopefully it's not the lift pump going fubar!

Teamy could be right there - your best bet would be to hook it up to a PP2000 & watch the live data to see what's happening. The codes alone don't really give you the full picture.

While it does look like you have a glow plug problem, it definitely won't be causing the limp problem, you may be better leaving that bit for now.

Cool, thank you ..... now to track someone down with a PP2000 .... hummm

I had error P1352 on my 2001 HDI90 - This did cause the car to go into Limp Mode - Replaced with Glow Plugs from Halfrauds.
Fault cleared immediatey. 87 miles later went back into Limp mode - Code P1352 - Removed glow plugs, all distorted.
Halfrauds replaced them with a new set - These lasted less than 500 miles. Each time they failed car went into Limp mode
Halfrauds gave a refund. Went to EuroCarParts for a set, 3000 miles ago and still working ok.

Hence earlier post not to use Halfords glow plugs

Yeah I've herd bad things about halfords parts!! Shame they used to be quite good!

[mattyf]

Right .... quick update.

I managed to clear all of the electrical faults ..... there was few wires rubbing and caused them to short .. now sorted.

Yes the “Heating circuit pre-heat” fault was indeed glow plugs, so thanks to all!! Fires up a dream now!

The only fault now is “Intermittent diesel High pressure. Lack of pressure” which is now turned into “Intermittent diesel pressure sensor” . Has anyone had this problem? Is this the sensor attached to the bottom of the fuel rail? If so, can it be cleaned or will I need to buy a new one??
