peugeot 307 power steering fault.

[slugger]

Intermittent failure / partial failure of the power steering which resets via the ign sw, all fuses checked , fluid changed , the garage has fitted a recon motor/ pump but the problem persists. Has any one had a similar problem I've run out of ideas and so has the garage.

Have you checked if the battery is fully charged ?

Hi Paul, yes there is a new battery and I am getting 14.3v from the alternator, however I feel that the fault is an electrical problem affecting the ECU.
I need to know how the inputs to the ECU perform ie built in systems interface , ABS , and the ignition sw supply. and how they control the motor starting sequence.

I have the same issue with my 307cc. Ive changed the 70amp fuse in the engine fuse box and cleaned the contacts as i had found this tip on several other sites but that didnt help. Ive now discovered that the power steering fluid actually needs to be overfilled due to some sort of manufacturer error so that is the next thing for me to check. After that I also found some advice saying that the connections to the pump can become dirty over time so I need to take the front passenger wheel and arch liner off then disconnect the connections. Clean them and the surronding area with appropriate cleaning solutions and then reconnect. If after all that, it still doesn´t work then I´ll possibly where you are now and out of ideas. So hopefully someone else sees this thread and can give some advice.

Hi Worthers ,the supplier of the recon pump has advised me to flush the system with 5 lt's of flushing fluid before using the correct fluid . the garage tried this to no avail. however it may work for you if you havent cured the fault. The recon pump is being sent to the supplier who is very helpful, to test it before returning it. I have checked all the inputs to the ECU and they seem OK, the ABS allows the pump to run when the engine is stopped providing the 12 volt to the motor is OK . hope this helps if you have a solution to the problem please let me know, I am considering scrapping the car due to the lack of information available.

Hi All, how do I identify a power steering pump? Can I use a 2003 pump to replace my 2006? I have found one in the scrap yard and would like some information.

Did you guys solve this issue?

My 307 14hdi, seems to be having the same problem. Occasionally my power steering pump fails and it returns to normal if I switch off and turn the car back on. Don't know if it’s a coincidence or otherwise but the problem persists more when the AC is on.

Fluid is ok.

Just a point worth mentioning although it may have no bearing on your cars at all. Intermittent power steering on older cars can be down to leaks of air into the intake side of the pump, caused by aged hardened hoses and failing seals at the intake port. That can result in air bubbles getting into the fluid and subsequent loss of pressure in the rack. After standing the system will self bleed itself as the air bubbles back up to the reservoir giving you back full operation until the leak builds up the air bubbles to the point where you detect failing again. Just an idea but worth checking the hoses and connectors to make sure it is not your problem!!

Thanks for the tip.

Regarding my problem it surely is electrical, since when I turn on the AC the problem is more evident.

Hi all, Ive recovered the Power steering pump from the 06 in the scrapyard bit of a struggle as the front wheel had a locking wheel nut ! However I will be fitting it tomorrow all being well, wish me luck!

Any update guys?

Hi all, I got round to fitting the PS pump from the scrap yard , much easier than removing it! Delayed for a while due to neck problems, however thee pump was fitted and and filled and lo and behold operated correctly at the first turn of the key!! I could'nt road test it due to MOT and tax which delayed my post but it has been working fine for the last 3 weeks. I suspect that if you are fitting a replacement motor make sure it is from the same year and keep all the part numbers etc from your motor to avoid any modifications electronically.
good luck,
