Hi there,

As said before bought the car with electircal problem (the wet footwell syndrome) which i still havnt got round to fixing (this month hopefully)!!

Anyway, since owning the car although im a little heavy footed, i have never been quite sure whether tim getting the correct mpg. Also sometimes though power us there, the car can feel very unwilling and un responsive and other times it feels very willing and quick of the mark. Bought the car with intention on saving money and so i overlooked its faults to a degree and have tried to concentrate on saving money. Well the other day was looking through cars paperwork and found a diagnostic print out of when i got it diagnbostic checked when first bought it (i didnt even realise they gave me a print out). At the time they said they could find nothing wrong (This is bloody robin and days peugeot of bristol, SCAMMERS!) . Having looked on the print out i have seen that i states the following:

Engine ecu - remote permananet fault. Brake comntact signal. No communication. Intermittent fault. Fuel pressure regulator fault. Stop requested but regulator still active.

Engine ecu: ECU Fault code P1138. Engine speed: 450rpm Regulator current: 71ma. Measured fuel pressure: 118 bars. Engine status: cruise control off, power latch active, air conditioning cut off inactive, EGR not active. Regulator OCR: 5%

Engine ecu: fault code p0571, engine speed 0 rpm, accelerator position 60%, battery voltage 60%, ignition controlled positive information input: No.

Built in systems interface: presence of fualts: MFD: ECU HAS NOT REPLIED, RADIO: ECUE HAS NOT REPLIED. CD PLAYER: ECU HAS NOT REPLIED. iNSTRUMENT PANEL: PRESENCE OF FAULTS. air conditioning: ECU HAS NOT REPLIED. Engine ecu: NO FUALT FOUND. Power steering: THE ECU HAS NOT REPLIED.Anyone understand all that??? I can only guess, im only mechanically minded not electrically!

Oh yeah and at the time and still as it happens, the abs was not working so the po571 code is probably that. The reluctor ring snapped off and i havnt changed it yet!

With that many faults you have a bad connection to the body systems interface, with the wet footwell, searching on this site shows that this is a common fault.

PS I live in Bristol and like playing with cars.

Thanks poddack! the mot runs out on the 3rd of march and ive got a couple of things to do. With hopefully more advice off here and some more investigation ill try give everything ago myself but if i get stuck at all ill take you up on your offer cheers! Nice to know theres a fellow friendly "DIY" 406 owner nearby!

All that means absolutely nothing. Stored fault codes are only of use if you clear all them before taking a reading, which when it comes to engine-related stuff usually involves driving between the clearing and the reading.

Cheers. I have just take up carpet etc in drivers footwell and found where peugeot have previosly tried to clean up plugs, reconnect and then bag up to stop any more moisture getting in. Bag showed signs of moisture penetration inside and so did the plugs, though not as bad as some guys pics on an old topic off here. I guess chopping the plugs off and soldering them solid together as i ahve previously mentioned on a thread seems like the first step!

If you do chop them off and resolder them, get some self amalgamating tape to wrap them up in and put a dab of silicone sealant at each end of the joint before wrapping them and you will never have a problem with it again, it makes it waterproof enough to be used underwater
