Thanks Chris, having been fine on your BX, I'm sure should I ever need to replace the HG on my 405, the Multi-Layer will be fine. I think the BoL quotes four thicknesses of Gasket, but the differences are fractions of a millimetre; I'll get the thinnest multi-layer I can find if the job ever comes up

307 RESTYLING 5 DOOR SALOON 1.6 i 16v 110 (TU5JP4) 4-SPEED AUTOMATIC GEARBOX

P0606 is an uncharacterised Engine ECU fault - so nothing further on that one.
and C1381 is not present in any fault diagnosis I have, so very sorry, can't be much help on that front.

That ground lead in the background (yellow crimp-eye connector) is a DIY mod. Perhaps see where that black wire leads to, and you might get a clue what is was meant to do.

I'd change the Lambda sensor then clear the codes they are possibly related to the lambda

It looks very much like the Turbo Vacuum Solenoid Valve (item 1), you can see the 3 air unions (3, 4 & 5) on the diagram that correspond to the pipes that have been cut off in your picture.

Your choice of course, but not recommended when it comes to explosives in safety devices.

Second hand units can be got for a reasonable amount. A 206 driver airbag module - £10 (49 z?otys); a Comms Unit £34 (169 z?otys). What price safety?

I'd sooner forego an airbag rather than risk it going off at some random point that would likely cause a...

MAF cleaner would be better and don’t touch the wire.

I would make sure the injector clamp bolts are tight (and checked every service). Volvo (who use a derivative of the PSA 1.6 HDi engine) do this as a matter of course, and they don't appear to get the problem with 'coke' in the oil, blocking the various pathways and filters.

Thanks - Excuse to buy more tools as my normal torque wrench doesnt go...

It will be there, but it is hidden inside the exterior shell. You have to take that off to locate it.

I covered 60 miles on the new oil it's still a little notchy going down the gears especially until it's warmed up. I been reading online about a fix for this problem tho what the fix is I have no idea. When I changed the oil I put in 1.9l as I read 1.9L and 2L on different sites. Is 1.9 correct the VIN is VF3**************[VIN obfuscated, can be read by forum staff]. There's no whine from...

Hi, I'm no expert, but you could probably get some speaker cable and run it from the interior light to the door. This would include trying to route the cable out of sight through the rubber seal that the door closes onto. You may need to drill a small hole in the door to run the cable through but shouldn't be too big. Maybe use a grommet.

This is...

I drained 2lt ( which I put in a couple of years ago) and filled with 2lt fresh oil. 2lt is the volume stated in the Haynes manual - it that accurate enough or should I also do the level check?

Ive not had a chance to investigate this, it is working fine from the button on the key and there is no internal button so it must either be the button or a break in the wiring. I shall let you know

Ive not looked at nine yet, so if I need sensors i will learn from you David and get a genuine one!

Thanks mate

Citroen replacement part number: 1706Y5. Brand new OEM is £1145.72 inc. VAT
or they do an equivalent, part number: 1612916180 at £800.54

Item 10 which is shown with the heat shield on of course. Normally you would also replace the fitting clamps at the same time.

Sometimes the parts exploded views can be a great help, also ECP to find out compatability/sameness.

Corroded in pads seem more frequent these days. I service the pads ( remove, de rust, paint and lube ( the backing plate and where they sit/rest in the pad holders ) before and after winter. A hassle yes but worth doing if you have the kit and...

My Suggestion mate is to check and clean the Mas flow sensor with carb cleaner,it doesn t take a lot to throw a wobbly,cleaned and replaced one over 10yrs on an old Fronty, was a good car to me really. Had me stumped for a couple of hours,put a meter on the connection from ECU and rev it,if you get differences in voltage,ONLY about 5v MAX. if you...

Thanks for the replies. Sorry I've not been on line.
2 issues.
Black smoke up hills, not enough air or dodgy injector.
Slight oil leaks, which might be worsened by crankcase pressure.
Anyway, new development is blocked injector, can't remember code, and an ominous rattling ??
Sorry I completely forgot about those codes. Do you have your VIN, as I...

Thanks Picasso, no alignment marks in this case (forget where it was bought from as from my spares) Anti-Roll Bar is different on the 405, but aware that on the 306 its bolted to the wishbone

Appreciate the trouble.

Yes, the axillary adapter was recognised after connection without enabling as you suggested Marc - thanks Alex.

I told the wife I had left a wire off she said you're very stupid not much sympathy there. :rofl2: cracking

Great that you sorted it though,

Great, they went back in fine, thanks again Marc - Alex.

Ensure you have the correct brake switch too and don't forget to read the advisory section on using Diagbox first of all:

Diagbox Warning

Thanks Marc, it's not the timing belt I was replacing only the alternator drive belt. Apparently most of the 1.4's had a spring loaded tensioner some like mine have no tensioner and a stretchy belt. The bearings in the guide pulley are gone on mine at the minute it's just hand tight I didn't want to go down the really tight route in case I strip...

Thank you very much!

Also says pass air bag disconnected

Another 205td saved. :-D :-D

Excellent!

A heartening result, after a lot of forum head-scratching. A very instructive thread! :)

Brilliant, thanks Marc, it’s number 2...

I took out the battery and tray no relay apart from the one mentioned earlier. I then went to check the fuel pipes under the air filter and discovered 1 or 2 injector seals are gone everything is covered in gunk. I ordered new washers etc wont be available until Monday so I will clean up everything today. Maybe this is causing it to be hard to...

An update for those
interested. I have probed and tested and established that the ECU is now definitely receiving a signal from the clutch switch. I could even feel a difference on the test drive with engine rpm seeming to not fall off as rapidly when making a gear change, resulting in much smoother progress and easier shifting.

However...

It was the 'turning over quickly' that made me think there was low compression Chris, broken cambelt effect! though obviously not.

Peter

I feel kinda guilty about it. I changed the oil and filter after the switches and it's saying low oil level even though the level is perfect. So maybe that's karma? fast karma at that

Thanks Mark for your help and yes it will be filled with eolys 3rd generation tomorrow and system reset afterwards , regards Luis

There is no O ring according to Marc, Gibbo and Peugeot (parts Bristol). I fitted a new guide tube WITHOUT O ring and it seems fine.

So basically the header tank method? Drain the coolant from the bottom hose, refit hose open valve at heater maitrix and fill until there's no bubbles? Would I not need to drain the block to do a coolant change? What's a de-aeration chamber plug and where is it? Is there another bleeder on the engine? Sorry for all the questions and thank you very...

So I brought the car to a local mechanic but he can't scan it until Tuesday apparently he's on the top of his head but I'll wait as the scan is €30. Meantime I will attempt a coolant change can't do too much harm doing that!

Good shout! Is there a software version i should look for? The solenoids i swapped had the same part codes - is it possible they run at different hz ranges?

Thanks !

I would need this as there are several 1.8 engines and several 405s, so I would need that if you want clarification.

Thanks guys, mostly intended as a bit of a useful FYI for others.

As was said in another thread recently Sparksie, nothing worse than not using a car regularly.

Thanks Marc!

Thank you very much for you help Marc.

This is very useful information.
Actually, the cost on the website is almost same as the used one I have now but I have no idea about the cost of shipment.
Anyway, I will check. Thank you.

Makes sense, wouldn't that show up on the diagnostic?
The gauge in the instrument panel rises as it warms up & sits at just below 80Deg.

Ok, thanks gents! That’s very useful info! Will bring the update as soon as the problem will become sorted.

Its integrated into the com2000 unit, the lighting & wiper stalk module.

Still poking around under bonnet 16 pin black plug on fuse box lot of the wires have no continuity like I said when I live fuse 15 the fuel pump kicks in but won't start got to be broken wires doing my head in
