I got access to the servicebox too (i guess that's what you were talking about commie ?) ;

 

Nope, I use www.elcats.ru parts catalogue. Great source, but the registration is tricky and it's only in Russian (however, Google translate might help, I guess).

Pepper you are a Peugeot owner - any advice on getting rid of this car? I'm wondering if it has any value "parted out", rather than sent to the crusher. The engine and transmission are in perfect order and strong, hardly any signs of wear, but the electronics are hopeless. 

 

There's a Thai car breaker in Facebook specialising on French cars, but I couldn't find him via search, all lettering in his posts is in Thai ?

Updating this topic -  my friend in UK unexpectedly found and sent a Peugeot MAF to me (no idea if right one). Alas now it is in Lak Si Mail Center according to his tracker, so it seems likely it's captured by customs. Anyone have any experience with the automotive customs?

Spare parts usually go through with no charge, unless it's too many in one package or they are too bulky. Don't worry about it.

Update - no news yet about the part, as I've not been to the office to see if it or some customs notification came in. Today visited my mechanic, and I asked him if he knew of any salvage yards that focused on buying Peugeot or other hopeless brands for breaking up, but he took me behind his shop and showed me a similar 405 he said he'd been trying to sell for 5,000 baht for years, but no one wanted the parts. This was the potential donor he was thinking of for converting my car to carburetion, but it's the 1.9 liter while mines the 2.0 liter so it won't fit. 

BTW he seemed very tired of having the car at is shop, where it has been for a month or two, so I think I'll have to take it away somewhere.

This is a long shot but might be worth a try.

 

I would guess that the nest place for second hand Peugot parts would be at a breakers yard in France.

 

Using Google translate you could try to locate one via the internet and enquire about the MAS and shipping fee. Also look in French motoring magazines.

 

I also live in the boonies and had problems getting my rare car fixed. In the end it had to go and I replaced it with a cheap but clean Vios just to improve the spares availability problem.

Wow, totally unexpected development - I noticed an old  contact on my Line renewed today, under the name "Peugeot mechanic" - a guy I'd met driving a beautiful 406 about 2 years ago. At the time he said he'd come to Mahasarakham from Bangkok to work on a Peugeot, so I took his number. 

Anyway messaged him and he claims to have relevant parts, for example a solenoid for MAF just 500 baht:

Updating this topic again - I received the Bosch MAF at the local post office, with 880 baht in customs duty to pay. I showed it to the mechanic, but his current theory is that the MAF is fine, only the wires and solenoid feeding into it are bad. The Peugeot guy I put him in touch with was unable to find those parts, but he and the mechanic agreed some Audi parts can be substituted. So at this point we're waiting yet another week for these parts to be sent. Meantime he broke the cutch cable connector driving the car around the shop grounds - apparently a trouble spot with these cars, and it broke once before for me. Hopefully he'll figure out a way to fix that, as he broke it.

By coincidence , my check engine warning light came on a month ago. My mechanic used his trouble shooter on it and it said the MAS was the fault.

 

I ordered the correct cleaning spray from Lazada and cleaned the MAS. Check engine light stayed on. After checking YouTube I tried some other tests with no result. I began to sense the MAS was not at fault.

 

Back to my mechanic for another go on his diagnostic trouble shooter. He had lent it to somebody so he took me to another mechanic friend to use his instead.

 

New guy got to work and the diagnostics indicated a secondary MAS. As he disconnected this for an examination, one of the wires leading into it was found to be not connected and loose. They disassembled the MAS and re soldered the loose wire onto its metal socket.

 

Result ....fixed ! Engine warning light out.

 

It was only then that I figured out the probable chain of events.

 

A couple of months back I had stayed at a hotel in Bangkok and been obliged to park on the street. In the morning I decided to check the engine oil for the return trip. It was then I noticed that a rat had gotten into the engine and burrowed its way into the thick soundproofing under the hood leaving a pile of debris on top of the engine all over both MAS sensors. It now seems probable to me that the rat was standing on the MAS wiring while he was digging with his front claws and had loosened up the damaged wire.

 

Just returned from a long trip and everything normal again. Although I was able to drive before with the faulty MAS , fuel consumption had been worse and acceleration lumpy.

With that money you could have bought the service manual, and a DMM, found the solution yourself, and have the problem fixed.

Save chasing around trying to find parts - and skilled mechanics - in an endless merry-go-round.

You mean fix it myself? Impossible. Anyway even I were willing to get greasy and calloused, and spend thousands on wrenches and so forth, the essential problem is the same - no parts.

Interesting - it does sound like a similar problem to mine. However in my case "engine diagnostics" don't work. When they hook up that machine zero information is transmitted, instead they've been testing each component and wire piece by piece using a kind of electric meter - to see if current's getting through.

DMM means Digital Multi Meter. 200 baht. The service manual will give detailed troubleshooting charts to test each component, no tools except the DMM required, and the ability to read English.

This will narrow down what is wrong, instead of chasing parts that you have no idea - or your mechanic - if this will fix it.

But up to you. Must be fun as you keep on doing it the hard - and not very successful - way.

Weeeeeell, I can tell you that my 1988 Volvo 760 V6 Estate had the most complicated electrical system I have ever encountered, seemed to work on resistances...The car was fully controlled by tech....For sure a novice and me would be stuffed..

^^^ Hence the need for a service manual. If you can read, and insert 2 probes, check the display with the manual ...

All is revealed

I have made my recommendations. Shared my knowledge with what will find the problem.

Follow, don't Follow ... UP 2 U

I will continue to read the posts - and 555

That remind me of....?

Updating - just visited the shop, where he claims to have fixed the MAF related running problem, but due to the language barrier he couldn't explain how. The clutch cable remains unfixed as he says none are to be found in Thailand - and so it begins again. 

One reason I remain highly skeptical that he's actually fixed the MAF/momentary stalling problem is that without the clutch cable he is unable to test it *under load*.

Updating - he stated a couple of weeks ago that he had the replacement clutch cable, but that he could not "pull" the clutch cable. No progress since. Beginning to think he plans to just leave it in his yard forever as they do. 

He sounds like a bit of a plonker...?

Thank you. To live is to suffer, particularly when one owns a Peugeot. 

My mother had a Peugeot in the UK. She needed some electronic parts for same. Went to the main dealer and was told that the bit's I wanted weren't available anymore, I would have to go to a breakers yard. I couldn't believe my ears as the lump was less than 10 years old. EEEEEEEEEEEEEEEK.
