Suspension sinks on Sundays! C5 X7 that works hard + 206 GTi HDi (and 406 Coupe and 306 HDi). - MattBLancs

Trivial stuff first:
Reversing lights fault: (B) putting this down to the LED bulbs I've put in there. As per (G) car is happy they work - as are my eyes watching during above test.

Parking sensors: never worked as long as I've had the car.

Suspension faults are a bit odd, cleared will see if they come back.

Flow meter, cruise control, etc - it does knock the cruise control out semi regularly. If paused (having been in use earlier on same journey) when you come to "resume" via the pause button, instead you get a flashing " - - " and cruise control will not engage for rest of the trip.

Slight clutch slip at present if, sorry, when I am being heavy handed with the throttle. Did wonder if the engine speed Vs Road speed disparity during such slip events was behind some of the faults. But does not seem to be the trigger for cruise control falling over. Has never slipped when under the direction of the cruise control (as that tends to be gentle inputs obviously) only when I'm giving it some welly.

Not mentioned as yet, but will attempt to top up DPF additive tank at the weekend, have the rest of the stuff bought for the 308 SW, which "suits all 4 types of DPF".
It thinks there is "666.2" ml in there, we shall see!

[Huskyxantia]

666.2 or a split pouch, did a 207 last year it said ther was over 500 till i dropped the cover of the tank , wearing 2 pairs of gloves , nice thick treackle everywhere , split pouch sort of still half full .

LED bulbs not good , used them years ago caused weird stuff to happen

They are fine if you get the right ones. I had them as sidelights in the C5 as the tungsten bulbs lasted only weeks, LEDs lasted years and were still in when I scrapped it.
Same with the Civic, reversing lights for that and they were excellent although the placement of the reversing lights was rubbish.
That set even came with load resistors, not needed.

[Huskyxantia]

Mine were , led from the land of junk ... china made , rubbish ..

[myglaren]

Pretty sure that mine were Chinese too. Long gone now though.

[MattBLancs]

Thanks all, mine are cheap eBay items, no load resistors provided (not measured their current draw, but don't believe they've anything internal beyond what required to make the voltage suit the LEDs themselves)

I'm particularly inclined to put LEDs in the reversing lamps given the standard filament bulbs were melting their lenses, as per here:

viewtopic.php?p=750570#p750570


I did have cheap T10 type LEDs in front side lights but they were poor quality and did not last long. Much to my surprise as had them on another car on the past and lasted well.



Car run well today, no error messages. Must get to the bottom of the coolant losses, needs a top up frequently. Which obviously isn't a long term solution. Need to get it up in the air, nothing obvious from above that I can see

[Huskyxantia]

Coolant losses , i did read somewhere airlocks in the thermostat housing then this moves causing hot spots and coolant evaporation cant remember where i read this , but other places egr cooler can leak slowly , oil filter housing & passenger side footwell if wet is the heater matrix hoses there alloy with o rings and werid clamps these are know to have o ring failure, was the first repair i did to my 308cc.

If the parts Asia site is correct, then thankfully it's a proper tank rather than a silly, vulnerable pouch.

All good thoughts and suggestions thanks:

Heater matrix: hoping not. Have no signs of dampness inside, no condensation on windows, odd smells etc.

EGR cooler is well buried i think, down back of the engine, hoping it's not that.

Oil filter housing - interesting, will look there. (Rectangular heat exchanger thing bolted to the oil filter housing = molded seals between these two) that's front of block, so would be surprised if it's that but not visible.

To be honest, I'm generally surprised I have not been able to spot the source of the leak yet, it's loosing it at a fair rate when running (no puddles when parked up)

[Huskyxantia]

If egr cooler then windscreen scuttle panel needs removing it opens things up a tad, if its from the head gasket you would see the white fog cloud when driving off. If the oils clean then its not the head or no steam fog from exhaust then again head gasket should be ok. Mind you if your getting the risk of clogging dpf stuff that could be water/coolant. My picasso is due to be sorted this weekend , 2 friends are pulling the engine & gear box out in one lump , got a leaky head gasket ,1.6hdi plus a whistling thrust bearing. Hope to be all sorted by Sunday evening.

Brief update, some pictures and add the words on later

Wonky track rod end detached from hub.

Old and new. Flats (inline with my thumb) suit a 19mm spanner which is handy

Track rod, liberal copper grease

Driver's (right) side completed

A left hand side changed too (seemed ok for play)

Track rod end lock nut: 19mm
Track rod end itself has 19mm flats to allow you to grip it (great idea!)
Inner track rod has 13mm hex beyond the threads.

Track rod end cone nut (hub end) is M10 fine thread Nyloc. Original (with the weird plastic washer thing) is 16mm, replacement is 17mm

[MattBLancs]

Couple of arch liner fastening positions devoid of clips

Not happy with the look of this bush:

Another angle of view

Front Wishbone, rear bush, front left

Just for interest, I took the (intact and good condition) rubber boots off the old track rod ends. This is what counted for grease in the failed joint!

Mud? Or at least Crud!
