Codes P0200 and P0380 on my 2000 2.0 HDi Rapier 90 - Tad
Hi All

My Pug keeps randomly stopping and my engine light is on so I bought a code ready. the codes it came out with are:

P0200: Injector Circuit Malfunction
P0380: Glow Plug/Heater Circuit "A" Malfunction.

Could someone please explain in more detail what these codes mean? And what I can do about them, you know, what simple things I can check before taking it down to the local garage? Please explain things really simply - I'm not that technically minded ;0)

Many Thanks

Tad

An HDI can be a nightmare even for those that are technically minded; so don't rush in based on a couple of worthless codes.

P0200 is just as it says; some sort of unspecified malfunction with the injector circuits. As they are all totally separate; it's pointless.

P0380 is commonly found on these - one, or more, of the glow-plugs has gone. They don't use them for starting, just after-glow, so not a real problem.

You really need the codes read with a proper scan-tool. There may well be manufacturer-specific codes there that your tool will never access. EOBD P0xxx codes are dying-out fast; nearly every code is P1xxx or P2xxx now.

When does it cut out? At speed; or coming to rest?

Hi

Thanks for the reply.

It totally cut out this morning on the way to work and now won't restart. There was an accident on the motorway and for an hour I was just sat there ideling. Came off the motorway and at the first roundabout, when I was pulling off, it cut out and now won't restart.

Got towed to the garage!!!

Yay!!!

Thanks again for the reply

Sounds like the low pressure pump is on the way out to me.....

The fuel would have been getting hot [and thin] with all that idling and no airflow over the fuel cooler.

Taken with that P0200 code; [and I'll bet you've got P1112 and P1138 in there too] the likeliest cause [of many] is a cracked injector leaking back excessively and dropping the fuel-rail pressure. Might be the pump; but I've never seen that code come up before.

It'll probably start when it's cooled; get the garage to check the rail pressure; the injection variance figures and, above all, do a comparative leak-off test on the injectors.
