Peugeot 406 HDi - Limp home mode

£67.50 I was just quoted. Basically an hours labour. Jesus. How much do Peugeot technicians earn? £8-9 per hour?
I know.. Its a licence to print money.
I reckon they (the dealers) have become a lot more expensive since service intervals were extended. Our older oil burners used to require servicing every 6k. With some of our fleet now having 18k service intervals, the dealer is effectively missing out on charging for two services.
I guess that charging an hour labour for a 5 minute hook up of car to diagnostic box is an example of the dealer trying to recoup its losses anyway it can..

Just going to call my other (more experienced) spanner monkey. :fingerscrossed: and find out if he has the ability to perform pug diagnostics.
I will NEVER buy another Peugeot! These bloody things are non-stop faults. Skoda's on the other hand...
If it is an emission related failure then any diagnostic scanner will read via the J1962 socket. For example P0096 = IAT Sensor 2 (intercooler air temp.) circuit range /
performance.
By emission related, I mean any fault that restricts the engine from performing within legilative emission requirements. Having said that, a dealer is unlikely to provide you with the code so that you can get it fixed elsewhere

Firstly, if it is an emission related failure the OBD code will be read by ANY commercial or dedicated scanner. It is illegal to withold these codes.
Secondly, I doubt whether the 406 would have a particulate filter, but would suspect that perhaps the catalyst has failed - thus causing the limp home occurance.
Without the code you may never know.

The scan-tool I just purchased will even pull proprietary codes for many manufacturers.
As its a major fault code (has to be to put it in limp home mode), should show up at least which area the problem is located. On an aftermarket device.
The manufacturers don't technically withhold fault codes, OBDII has limited scope and the ECU can detect faults with more detail. Several faults could be grouped into one fault code as that is all that is offered. The detailed faults can only be accessed through bespoke software and interface. Thats why they get to charge you an arm and a leg.
Although I have heard of manufacturers not supporting all OBDII Codes even when they could.
Try your local garage, with my previous car I spoke to the guy at mine and he kindly read mine for free.
I have a bespoke one for my current car as I worked on the software.

may seem like a daft question, but are the brake lights working or staying on all th time??...
Not had anyone flash on the motorway or anything, so I presume not.
Update: Seems to be a valve in the Injection system that's coming up on diagnostics, and a glow plug is out. The valve section is £250 so I'd rather try the glow plug first, see if it makes the other fault less noticable.
Surely if the glow plug is out, it would be down on power and run sluggishly?
The other fault is clearly still there. We cleared the error code from the car, to see if it was a historical piece of data that was putting the car into LOS mode. Driving home last night it left me on the Hard Shoulder of the M2 for a while (it's not really fair to pootle at 30mph while your car has a hissy fit
) So I guess we need to check the code again and see if the injection fault is still listed, or if it's just a glow plug.
Thanks for all the replies so far

I'd have thought a duff glow plug would just make the thing harder to start. Once running, it should make no difference to performance whatsoever - and it certainly shouldn't trip the car into limp home mode.. SS2. said:

I do know that a diesel ignites through compression, but I thought a glowplug helped it along a bit...
Oh no! That means it's the expensive one

Only the 2.2litre 406 HDI had a particulate filter
- The 90 & 110 bhp engines disnt have a particulate filter on a Y plate It is quite possible that the low pressure pump (in the tank) has broken up internally, sending swarf into the HP pump / injectors.
If you open the diesel filter assembly in the engine bay, you may see swarf in there.
Glow plugs is a possibility - faulty glow plugs can cause limp-home
Also check that the pedal sensors (brake & clutch pedal) have not come loose
A long shot is poor ECU connectors (the silicone sealer in the plug can break up and give poor connections)- tho with 300K on the clock it could be anything !!
Compressions is also a problem - each pot should give the same readings, I've seen HDi's with melted pistons - especially if they have had petrol in them
Hope that helps
