Posted: Tue Nov 13 2012, 07:59PM Hi I own a C4 2004 2.0HDi VTS and had it for around 4 weeks. These error codes came up last week when I took the car for diagnostics and wondering if you could tell me more or if you have encountered the same errors on your car? The depollution light is on. I have put dpf cleaner in with diesel and took it for a blast which shifted one of the error codes (cannot remember the code) and I think the emissions are ok P0183 Fuel temperature signal open circuit or short circuit to the plus P2565 Turbocharger position copy signal : Voltage above the maximum threshold I am taking a guess that these are just sensors on the blink? I have got a MOT this weekend, will it pass or fail with this light on? Also with buying it only a few weeks ago from a dealer who trader from his home address with a VAT Number could I take it back to him even though it has no warranty? Thank you for your time Kind regards Barry |

The depollution warning is generic, and could be anything associated with the fuel or exhaust system. Generally speaking, additives are a waste of money - getting the system hot for a long time has probably sorted the exhaust side of things. The turbo charger error is more complex: From our table: P2565 Turbocharger position copy signal : Voltage above the maximum threshold Possible Causes: Turbocharger Vane Position Sensor faulty Possible Solutions: Check Turbocharger Vane Position Sensor Check Wiring from/to Turbocharger Vane Position Sensor Check Connector Check Fuse However, look for simple solutions first - checking and cleaning, &c. before tackling jobs like replacing and calibrating sensors &c. |

Apart from flashing lights on the displays is the car running normally? Car may just need a long fast run and/or someone to clear the error log. Turbo should noticeably kick in around 1200rpm. MOT should pass as they only check ABS lights. |

This sounds like a similar fault to what I had, I had the turbo vane actuator replaced by dealer after about 2 months of diagnostics, this may not be the case for yourself as my car was noticeably different after the repair ( as if it has been broken for the last 18 months) also I had two error codes with this certain part and the 3rd code I had was fuel cap switch (unrelated) If the vane actuator is defective you should notice a sharp drop off in power the higher in the rev range you go, I lost all power around 3000-3500 as if turbo had stopped spinning altogether, mine was seized solid when it was removed an was unresponsive to electronic actuation, new one was around £170 plus fitting (£150ish) and cars been sweet as nut since  hope this helps although try the cheap fixes first such as a 30min drive above 40mph (if possible)

There's a bulletin on that P2565. The other fault code won't give you any problems. Basically it'll be turbocharging pressure regulation valve - damaged from water ingress. So the sensor will be giving off an incorrect reading all the time - screwing with the ECU. It's quite a big job as the turbo on the 2.0HDI is buried down the back of the engine - so it's a subframe off job to reach. The new sensor is £170.00 (part only) |

Subframe off means it's quite a bit of labour to change it...... Even there is no 'paid' warranty, a trader is supposed to give something like 3 months warranty so yes, it's worth contacting him If he's obstructive, well, tell the tax man and Trading Standards that he's trading from home........................ |

I wouldn't say the job was big I was charged 3 hrs labour for mine to get changed and got the car back same day, not sure how they did it though as didn't stay but definitely didn't have the subframe off. | ||||

I will agree with Phil also i had the same Fault code P2562 problem were the turbo was dying and they replaced the turbo which did not solve the problem, eventually took it to a citroen specialist and they replaced the sensor at the back of the engine drivers side (Turbo Electovalve) problem was solved. | ||||

Official labour time is 4.8 hours and does include removal of subframe. I guess you could just about get up there with little arms and hands but extremely fiddly. It also isn't a simple straight forward replacement the new sensor needs to be vacuumed up, it's resistance values checked at a certain vacuum and adjusted with shims as necessary. | ||||

Ok so thanks for your responses but is this essential that I get this fixed? With it only being a sensor? |

When I had P2562 my turbo was not working at all, and the run up to that is that sometimes the turbo would stop working. As it was intermittent I decided to wait until it completely failed. My car was at a specialist for a total of nearly 2-weeks diagnosing the fault, which turned out to be the turbo electrovalve and the vacuum pipes associated with this. As already mention you are looking at 4-5 hours labour plus the cost of the electrovalve. There are 3 of these electrovalves on the 2.0HDi, and the one that fails is the one you can't see, which is why it is expensive in labour costs. Subframe had to be lowered by the garage on 2 occasions as I had to return the car after the first repair attempt failed. I would wait until the part fails or you could end up changing the electrovalve and then have the same fault occur as it was not that part. |
