Electronic hi-jinks with the Partner today

First of all the ESP icon appeared, then the ABS and, later in the day an engine/gearbox one.

At various times it refused to change up a gear (auto) and the word auto, normally static, was flicking on and off. The cruise stopped working.

I got home by firstly stopping and switching off and on again, but that got very tedious and I discovered that if, with great care, I selected N then back to A(vance) it sensed the correct gear from the speed and selected it.

A friend who knows a thing or three suggests the ABS contacts on one or more wheel, and may not be serious.

Anybody recognise this and a possible solution?

It could well be abs/speed sensor or the wiring, it usually is on the passengers rear which will be the driver’s side here, inspect the wiring first as they can rub through making a contact on the metal of the suspension, then get the codes read which should tell you which sensor is throwing up a fault code.
It could be a broken abs ring but check the wiring/sensors first.

@Spardo There I thought you were talking about your OH David. :grin:

Thank you Colin, more or less in line with my mechano friend I think and I will get him to do a check as soon as he has time, but he is snowed under with work at the moment. I could go to the dealer who normally services it, but I know that they will just replace everything in sight at great expense.

@spj , You should see her laughing at the moment as she intones ‘chance would be a fine thing’. :laughing:


That is the problem now. Time was when we could do repairs ourselves or an under-the-arches guy would actually repair something. My first 25 years of car ownership involved ‘roadside engineering’. I once came across a pal setting the valve timing of his car in the street. I pointed out that it was a bit infra dig to be doing this oneself … to a 1950’s Bentey Continental Fastback


Now it’s simply ‘remove old, fit new’ - and that may not solve the problem.

My Peugeot 307 HDi has the fault warning light up, ‘anti-pollution system fault’ on the screen and goes into limp-mode on a long uphill climb in 5th. Peugeot put the gizmo on it and declared ‘new soot filter’. 900€ later - no change. Now they say, ‘new turbo - 1200€’.

I am certain I know what the problem is and how to fix it - remove turbo, clean out all the crap and free up the variable vanes stuck in over-boost, resulting from the previous owner’s last 3 years of 3000 miles p.a. short, slow, cold trips, but they will not do the job. I’ve asked but they refuse. Peugeot HQ won’t allow it.

I need someone who mends things. If anyone knows of such within a reasonable day return drive of St. Lo, please let me know.

If the ABS light is involved, it can be as simple as cleaning out the ABS sensors as they can clog with brake dust and stop tracking wheel rotation accurately, throwing everything into a panic.

Again I agree, also with Christopher.

This morning on the short trip to the shops, the ESP light came on but not the ABS so the automatic gearbox worked fine (also the cruise). Now also, since just before arriving home yesterday the anti-pollution light comes on. That is a rather alarming icon as it looks like an engine and to the uninitiated appears to predict impending doom.

On re-starting to return from the shops, only the anti-pollution light was on and everything was working fine. Not sure how long ago it was but this has happened before and I was told by the Peugeot garage that the reservoir needed topping up, a job only for them and the bloke lay flat on his back under the car to do it. Can’t remember how much it cost (if necessary I can check and when) or when it was, a couple of years ago I expect, maybe more. I asked when it would need topping up again and he said airily ‘never’. Amazed I pressed him and he said ‘oh 120,000 or so’. I told him that was hardly never to a car that averages 80,000 a year.

If that is needed again it is a bit sudden as it passed the pollution test on CT only a couple of weeks ago with almost no distance in between.

My young mechano doesn’t even have arches to work under, but he is a time served HGV electronics fitter and has done excellent work for me in the past. I think I will wait till he has the time to check it, I do very little mileage these days and may give up the dog journeys altogether soon.

That may also be the cause of some of the issues - I had a Peugeot 206 and it complained in regards to the anti pollution warning if i did not use it often enough. Usually it meant i needed to give it a good 30-45 minute drive in all gears to get it all warmed up and running properly - often the light would not come back on after a run. The other warnings may be electrical, possibly low battery can cause some weird errors on modern cars these days.

Sounds like something to do with the DPF.

Can be expensive if they fail and, yes, regular long runs are best for keeping them healthy.

I agree Paul (now have a diesel Volvo), the Peugeot was a petrol.

Oh, OK, wonder what the “pollution light” was then?

Petrol engines have a catylist and can still block, worst car you can have if you only do short journeys is a diesel, blocked dpf’s are common where a salesman sells a car that is only used for journeys backwards and forwards to the shops/pick up the pension once a week.

My garage suggested an O2 sensor - once I started to use the car regularly the errors did not re occur.

A catylist need to reach a temp between 200-400C to be effective.

All the above coincides with advice I am getting elsewhere.

What’s a DPF?

Diesel Particulate Filter - basically filters out the soot from the exhaust.

However they need to be “regenerated” - lots of short, cold, journeys mean more “active” regeneration which uses fuel, can result in unburnt fuel contaminating the lubrication oil (which can be catastrophic if regular oil changes are not carried out) and general bad stuff happening.

There are fuel additives available to help clean turbos, egr valves, oxygen/lambda sensors, dpfs and catalysers, fir both petrol and diesel engines. I’ve used them successfully in my FRRR (for egr sensors) and OH’s coccinelle (catalyst/lambda sensor). Worth a try, a lot cheaper than going to a garage/stealer.

Keeping modern diesels happy

  • Regular long runs, especially if most journeys short
  • Stick to the maintenance schedule like glue
  • Main dealer (OK, ouch, but a new DPF is a bigger ouch) or specialist independent (maybe slightly lower ouch) servicing.
  • Watch the oil level between schedule services - if rising might just need longer runs but early oil change will limit damage to turbo/DPF and/or causing engine runaway.

What is the vehicle David, Peugeot partner?
Have a look on youtube for the fault.
On the Renault Nissan 1.5 diesel the ABS and ESP lights come on when a small diameter pipe with a pressure switch on the end gets blocked with dirt from combustion. Nothing what so ever to do with the ABS or ESP systems

Yes it is John, and to Paul and Mark, the particulate filter was regenerated 120,000 kms ago not all that long after the anti pollution reservoir (or whatever) was topped up. That would be about 3 years ago, I haven’t done a great deal of mileage in the last 12 months.

This car has always been serviced by the agent spot on 20,000 kms since I bought it over 4 years ago, and exactly to the published schedule.
