the new amplifier IC arrived yesterday and despite replacing it, just before going off to the dentist for a filling, the same fault remains :twisted:

So, back to some deeper fault-finding... I WILL fix it but I'll have to rig it up to run on my workbench rather than trying to fix it dead and just testing it in the car...

This wireless has now become a challenge!

Can you re-cap ( :roll: ) the symptoms?
A possibility is that a speaker wire is shorted somewhere.


Which would explain why I could get it to work by hitting the door (as I said) Jim :)

Also try flexing the PCB. Some of these single chip amplifiers have a feedback input... it's possible if that's gone astray due to a crack or dry joint that all sorts of mayhem could result... especially if it's proven to be affected by percussive maintenance before.

You may be right Mike... My research is leading that way as I believe the amplifier IC (a TDA8561Q) is going into protective shut-down on one of the four channels and hence the noise... The channel will switch on and off in square waves at a very audible frequency which sounds very much like 'motor-boating'. This all according to the IC data sheet...

All caps (always major suspects) checked good ;)

Oddly, the ex-Xantia temporary wireless does not show the same symptoms and all four speakers seem OK..

It's looking wet today so I may get more done on this today if too wet later to carry on with the Activa...

Yep, for that age of car there is a requirement to have at least one rear fog lamp and not more than two, and if one is fitted is must be either on the centre line of the car or off-side.... and time to get your vernier calipers out - for the distance between the rear fog lamp and stop lamp there must be at least 100mm between the "light-emitting surfaces of the lamps when viewed in a direction parallel to the longitudinal axis of the vehicle" :rofl2: :)
That makes full sense :) Thanks! The distance is good as fog and stop are at opposite ends of the cluster ;) I can rest happy on that score knowing I'm legal!

Tried that and checked very carefully... Touching one channel input on the amplifier IC effectively bypasses the input signal to earth and mutes that channel and allows the other three channels to perform normally... So not exactly percussive... More using finger resistance to damp things down!

Despite best laid plans I got nothing done on the Activa today :(

After spending a lot of the morning enjoying a moist and most excellent parkrun, Sally reminded me in no uncertain terms that she is very much a Citroen on the way home :twisted:

For a couple of days she's had an occasional hesitation and misfire when seemingly half-warm. This would be very brief an then clear, never to return until next time...

Today though was a different matter.. Leaving parkrun she started fine and for the first couple of miles ran like a dream. then she started to splutter, clear and the misfire and generally hesitate and feel well down. On reaching home she was idling very lumpily and almost cut out..

Stop, switch off and restart and she was fine again :? For a while at least...

The problem felt either like the coil was breaking down or she had fuel starvation.

I swapped the coil - I had a spare as she uses one identical to the Activa :)

No real improvement.

I swapped the fuel filter... Again, not a success...

Got the ELIT out and it recorded an intermittent oxygen sensor but live data showed it to be good :?

On another test drive, whilst watching live data, she almost cut out and this time the ELIT recorded a permanent throttle pot problem...

I then broke apart and cleaned the throttle pot connector and the engine ECU connector after disconnecting the battery and she then behaved perfectly on the next test drive of over 15 miles....

Typical feminine Citroen by the looks of it :lol: :twisted:

I'll know for sure how she is tomorrow as I'm going to trust her to take me to Nottingham for the Nottinghamshire Wheeler cycle sportive as I'm sure she won't let me down even if she does have another hesitation spell - switching her on an off seems to fix but I'm not going to risk the M1 - I shall go via the A1 up to Newark and head across to Southwell racecourse from there... Google maps says there's not much in it between the M1 and the A1 route time and distance-wise..

Last spanner job of the day was to check, service and prepare my bike for tomorrow.

Now to prepare my clothes and food for tomorrow ;)

I'm looking forward to tomorrow :) Maybe inn the afternoon I'll get a bit more done on the Activa - depends on when I get home and how tired I am after the ride...

If I were you Jim I'd also as a precaution just change all the vacuum hoses. Most of the "bolt on" injection systems like these are *ridiculously* sensitive to even the tiniest of vaccum leaks. At the very least I'd change out any that you can't readily see to examine, as Murphy's Law states that those are the ones that will leak.

This is from someone whose dealt with similar setups on several cars and really should know to follow my own advice by now, yet ended up chasing my own tail for a couple of weeks due to a vacuum leak a couple of months back...

Zel, that's a very good point... Fortunately the Saxo is not too well endowed with vacuum pipes but there are enough to potentially cause issues... Those to the brake servo, the inlet air selector an the carbon canister stand out as good suspects...

Those will be checked and sorted on the next foray! Thanks for the prompt :D

I should know too.. They were a regular nightmare and source of no end of grief on the 205s...

^^ Love it! Especially the end where the narrator say it 'takes the sigh out of cycling...' Priceless :lol:

Thanks for that Steve!

It does indeed but it could not been a success as it's not seen now in any form. Perhaps a small derivative is though and that's oval chainrings and similar claims are made for them....

Sally and I have made it to Southwell Racecourse with no issues. She purred all the way to Grantham where we stopped for breakfast. Started off fine. She had a couple of little hiccups about a mile up the road and then fine all the way here. Very frugal on petrol too :D

Most odd... I'll see what ELIT says when I get home...

Meanwhile I have a cycle sportive to ride... As do several hundred others already here :) This looks to be a popular one and not only that, the weather looks good too :)

A most excellent Nottinghamshire Wheeler Sportive today and really enjoyed...

A fantastic finale to the season for me... A gorgeous ride ridden over lovely countryside in gorgeous weather... The sun shone from a clear blue sky :) A bit on the cool side though but for November - just wonderful :)

Here's the ride as captured by my Garmin...

https://connect.garmin.com/modern/activity/2296871733

The pre-ride safety briefing was delivered as a poem which I thought was a lovely touch ;)

And here's the bike posing with Sally just before the off...

Own Work
Sally performed magnificently on the way home, she never missed a beat and just purred all the way... I filled her tank just before home and she returned 52mpg :) Not bad when ylou consider 60 of the miles on that tank were spent testing and tracking down the hesitation and misfire problem. I reckon she's good for 55mpg...

I do love her and a finer small car I don't think exists. I used to think the 205 was the best small car ever but Sally is changing my opinion... She drives and rides beautifully as well as being supremely comfy :)

I popped the ELIT on her just now and her throttle pot problem is now intermittent along with an intermittent oxygen sensor (again). I'll replace both...

Still, to be returning 52mpg whilst cruising on a cold day at 60mph shows things can't be too far out...

I did carry a full kit of tools with me today, just in case but they weren't needed...

The tools normally live in the Pug of Love... She did this to me when I returned them to her boot :twisted:

Own Work
All because she has iffy tailgate struts and her tailgate does not full lift without assistance... I walked straight into it :(

Actually, I think she's jealous of Sally and this was her way of showing her displeasure :lol:

The wound keeps on opening up and is going to prevent me from swimming in the morning. That's the real tragedy of it :evil:

The ride was well rewarded. A medal, a tee, a pair of socks, a neck warmer - very useful on a day like today - and yet another drink bottle filled with edible goodies :)

Jim, and Hell Razor James (as he was present at the time) may recall me smashing myself in the face with the Berlingo tailgate last year. Was stood on a kerb when I shut it and the extra few inches of height I wasn't expecting caused a gash and a big bump in the centre of my forehead!

It's never fun. Another friend of mine can vouch for why I'm exceedingly careful of the (totally square, not at all curved) tailgate on the Lada. I cracked my head on his one once and darn near knocked myself out. Have never actually knocked myself out, but that's jointly level with a couple of other mishaps for being closest!

Gas struts are something which we really should just replace as soon as they start to struggle - saves us pain in the long run!

...Saab has had them on the to do list for about four years now...

I have. Hilariously so, apparently. Back in 2009 I'd been for a bike ride one evening. Back then I had to bring my bike through the house and out the patio doors to the shed.
Took bike out patio doors. Closed patio doors. Put bike in shed. It started to rain heavy so I ran back down the garden through the patio doors...

The patio doors, as you will have read above, were closed. Why the hell I forgot they were closed, didn't notice they were Closed, or didn't stop running shall forever remain a mystery. Suffice to say, 16 stone of Mike running into them and making contact with the head first resulted in Mike coming round a couple of mins later in a pile outside on the floor. Mrs Mike was sat looking straight through the patio doors and saw me come smashing into them.

Had a sore head, went to work the next day. Only realised what effect it had on me later in the afternoon when someone came to me and thanked me for all my help that morning and I had no idea what they were on about. Then I took the train home (I drove 2 days, trained 3 at that time)..
I'd driven to work that day, and had no recollection. Didn't even walk to the car park..
