The initial problem was an Air Conditioner issue - on a Peugeot 308 Variant 10 1.6L 6SPA XSE 6 speed Sportium Hatch 2010 model. The car has only done 69000 km. The car is owned by an older family member (pensioner) and has spent approx. 18 months being run on sub-standard fuel – E10 and 91 RON. I am trying to assist the owner and have ensured that it has since been run on 98RON for the last 2 tank refills.
The initial problem occurred after 6 months of use of the sub-standard fuel where a combustion-related [i.e. an “engine management system faulty”] alarm occurred. Not long after that the air conditioner stopped working. I went to a local 'air conditioner specialist' who quoted $2500 for a new compressor - but I wasn't confident in his diagnosis, so I went searching for a Peugeot mechanical specialist. I could not find a local mechanic who is experienced in Peugeots so a journey of 120km away saw me attending a mechanical workshop (where European cars were advertised as their business). The mechanic indicated that the alarm was firstly D209H/53769 and 494H/1172 then upon reset became P1605 – he could not interpret these codes but recommended that the air conditioner pressure switch be changed. As this was a straightforward exercise, I purchased the unit and changed the old one but did not result in a fix. Consulting an electrical engineering mate, there was/is no electrical supply from the ECU supplying the compressor under normal operational conditions. The compressor can be operated with a temporary supply from the battery – so the issue is with the ECU responding to the “engine management system faulty” alarm.
Going back to the same mechanical workshop, the mechanic then replaced the thermostat assembly (apparently a common fault where the ECU doesn’t get a signal to switch the air compressor on) but surprise, surprise this also did not fix the fault.
Up to this stage, the car had been driving normally except for the non-functioning Air Con and that “engine management system faulty” alarm. More recently however, during a normal drive to the shopping centre, an “anti-pollution fault” has also occurred – the advent of this most recent issue has caused the car to go into ‘limp’ mode.
Here in the Newcastle, NSW [Hunter Valley], there is an extreme shortage of competent Peugeot factory trained diagnostic technicians (that I can find) so it has been a frustrating exercise to try to diagnose the root cause. Now in limp mode, it is problematic to use the car to visit possible mechanics in for example, the Sydney metro area.
The research I have done from this and other forums indicate that the issue could possibly be an exhaust or vacuum pipe leak, a faulty O2 sensor or even the catalytic converter.
The reason behind this post is to seek opinions from any Peugeot owner who has experienced a similar situation and if there is anyone out there in the Newcastle NSW area who being familiar with this type of Peugeot (and who perhaps has an Autel Scanner or similar) and would like to be employed to investigate the issue for us. All enquiries welcome ….
Thank you in advance, Jeff M.
