Davie's Activa Clutch

[daviemck2006]

Try sitting at 30 to 35 in 4th and give it full throttle. It does go off again and doesn't seem to affect it. Perhaps I'm maybe asking it to slog it out too much.

I think this is to do with the manual boost controller, and it running more boost than standard. I believe others have reported the same (non) issue in the past.

If it was overboost it would go into violent limp mode as the EML came on; you'd really know about it because it would feel as if the engine had cut out for a few seconds, a bit like if you hit the rev-limiter...

I'll see if I can find the old posts about it . It's not overboost, it's simply it detecting more boost than it should for a given situation, but it doesn't go over the limit set in the ECU.

I ran my ELIT across the car and no faults anywhere at all except for the 'normal' Hydractive one relating to the steering wheel position and that's cleared fine...

I could not provoke the EML to light on a lengthy test run either..

She's had an oil and filter change and is now ready to go home. She's officially discharged from the Activa hospital...

Job done!

Perhaps Jim has a stethoscope device that can be used for a couple of minutes to investigate the whirring noise that appears when my aircon is switched off - if Mrs. Ben allows me to take the Berlingo and not the C1! I'll be aiming to be at Luton for about 12:45 Davie, just email me a flight number I can track..

A whirring noise only present when the aircon is off is going to be the clutch bearing on the compressor pulley. The bearing is only turning when the aircon is off to allow the pulley to free wheel. When the clutch engages to turn the compressor the external pulley bearing is now no longer turning so a noisy bearing would be silenced.

This is a separate bearing to the one that supports the shaft in the end of the compressor - if that one was noisy it would be whirring when the aircon was on, and not when it was off.

Thanks Simon. Is it likely to seize and ruin my aux belt, and do horrible things to the timing belt, or am I safe to leave it for a while? Obviously I could just run the AC all the time too..

I'll take a listen on Tuesday... There's a big difference between a nasty grauncy one that's likely to fail and a smooth whine that might go on for years...

[Zelandeth]

Need any help giving the car any external cleaning, Jim?

Happy to help out with a polish, wax and plastic treatment etc. Have what feels like half a vanload of Autoglym stuff in the garage which I'm happy to share. Oh, and the clay mitt thing which is downright weird but astonishingly effective.

Wash, clay, polish, wax shouldn't take massively long, couple or three hours probably.

Zel, if you want you're more than welcome Not about now until the weekend and then furiously busy with something else...

Will be good to see you over the weekend or next Monday and I'm sure Davie would be delighted...

It was ordained that I'd finish the Activa yesterday as that evening Robyn said her 207 smelt a bit of petrol fumes...

I took a look and found she had a ruptured fuel line and fuel was spraying out in a fine mist

I immediately forbade her to use the car and she's now using my C1 whilst I get hers sorted...

Both of us felt she had a very lucky escape indeed. The leak is such that it could so easily erupted in a fireball... She had driven it to Surrey and back and then Oxford and back like it!

[Zelandeth]

Ouch...always surprises me how people will continue using a car that smells of fuel...for me that has always been a "pull over and immediately investigate" offence - learning to drive in a Metro where the fuel line passed the exhaust manifold by about an inch will do that I guess!

Will get in touch nearer the weekend regarding the Activa whether I drop by where or it drops by here (either work, all I need is water and a 13A power outlet ), seems best we send her back north as best we can!

Have to admit thaft I greatly enjoy making cars sparkly and clean...guess seven odd years at the garage rubbed off on me! Don't reckon I ever saw an Activa though...shedload of TDi and HDis, but don't remember an Activa...

[CitroJim]

I agree about the petrol smell Zel and what you should do but in fairness to Robyn it was not that strong in the car, it was strongest outside!

Gawd knows what would have happened if a smoker had been walking past...

I made up an emergency bandage last evening to stem the worst of the leak when the car was stationary and this morning it's all dry and free of fumes..

I can provide the tap and electricity even when not about
