General Car Chat / Zafira 1.4 Turbo petrol - Shed or not?
« on: 21 May 2018, 22:47:10 »
My brother is considering buying one. 2015 model with 30k on the clock IIRC.

Any horror stories? Anything to look out for?

It's got climate control, so hopefully not fitted with the incendiary fan resistor.

General Car Chat / Troublesome Volvo V50 Tractor
« on: 08 January 2018, 16:24:16 »
As I mentioned a few weeks back, my brother has a V50 2.0D which is giving him some issues.

I had a look over the weekend. Unfortunately, it's been "Motor Traded" to the tune of about 2k before I got a look in, so no doubt that has caused some issues which need to be corrected before the real diagnosis begins. ::)

Symptoms are that it "surges" a bit under light load around the "normal" driving speed range (1.5k - 2.5k RPM). Often it will slip into limp-home with very poor performance (i.e. no boost) until restarted, whereby it recovers.. for a while.

It starts and idles perfectly fine. On full-bore acceleration the performance is probably about right and it pulls smoothly. No nasty noises, smells or smoke over and above the usual.

On taking a look at it, I discovered the following:

Intake air temperature sensor trouble code, and reads constant-30 Deg. C on live data. This is the post-turbo sensor in the intake manifold. Looks like a little bead thermistor that's completely open circuit.  Would have been eliminated by now if the muppets had sold me the right part. ::)

Apart from the above, ECU is happy.

Couple of connectors left off, Breather pipe disconnected from crankcase, some signs of bodging of the wiring around the DPF pressure sensor, which looks new. Yep, it's been in the hands of some muppets. None of this appears to be causing any issues, and didn't help once corrected.

Oil level is about 20-25mm above the max mark on the dipstick. I suspect some fuel has got in there! :o

I can imagine the limp-home issues might be to do with the temperature sensor, in that the ECU gets nervous when it's been on boost for a little while without induction temperature feedback and stops play, but it really doesn't seem to be the whole story.

I can't help thinking the surging under light load might be a fuel or boost pressure control issue. I've heard that fuel pump issues on these can cause the oil in the sump problem, and might cause fuel pressure fluctuations. On the other hand, fuel in the sump has also been blamed on failed DPF regenerations, and the latter has, apparently, been recently replaced (although god knows why they didn't sort out the oil level issue).

Surging manifests itself as a regular about 1 Hz cycling of torque output. If you hold it at about 2.5 K RPM fast idle, you can also see and hear the revs fluctuating +/- 200 RPM or so about once a second. You can hear the turbo whine cycling up and down in pitch a little at this rate too. Sticky wastegate / vane actuator perhaps? :-\

IAT sensor will be replaced ASAP, along with an oil change and correction of level. Any further ideas?

General Discussion Area / My first attempt at making a video
« on: 02 November 2017, 16:53:38 »
.. and not that kind, before you reach for the "Report to Moderator" button.

I got myself a GoPro before heading to the highlands this year on my usual gliding pilgrimage.

I've never shot any video before, less still attempted to edit it into something anyone would want to watch, but the blank looks from family and friends when I tell them about bore them with my gliding exploits prompted me to try and help them "get" it.

Anyway, I ended up filming a flight that turned out to be my best yet in terms of altitude reached, so here it is, with the boring bits speeded up.

I was working up the courage to sucker the camera to a wing, and would have tried it on my final day there, but the weather didn't cooperate, sadly.

General Discussion Area / Camping Gaz shocker
« on: 16 September 2017, 11:12:11 »
Without mentioning the "event", suffice it to say that we are well appraised of the potential dangers of this product.

I have just tidied up my camping cupboard and found 6 C206 gas cylinders which I'd forgotten about, one of which was installed in a camping lantern.

Following aforementioned "event" I decided to remove such items to the shed just in case, but clearly overlooked these.

I know for a fact that the cylinder in the lantern was not empty last time it was used. The other 5 cylinders were new and unused, easily verified because installation in an appliance causes the top of these cylinders to be punctured to let the gas out.

The cylinder in the lantern has no gas in it. :o

One of the brand new unused cylinders has no gas in it. :o

I could sort of understand the cylinder in the lantern being empty, given that the valve on the lantern might not have been properly closed, or been knocked slightly open since. But.. for a new unused cylinder to have lost its gas is unforgivable!

So, a reminder, in case you have any of these items lying around. Keep them somewhere that isn't going to upset or harm you if it gets converted into a smouldering crater. Better still, just avoid them. >:(

General Car Chat / Helicoils
« on: 04 July 2016, 14:36:55 »
I have a couple of M6x1.0 female threads in the engine block of a generator that need repairing.
This seems a textbook helicoil application but I've never used one before. Any recommendations?

Ambulances, fire engines, plod and the air ambulance have been past. Bored, but some poor sod a few hundred yards ahead is having a much worse day than i.  :(

General Discussion Area / Another hero gone
« on: 21 February 2016, 23:47:37 »
Yesterday evening I came across a podcast that I'd saved months ago, and not got round to listening to, so I put it on. It was Eric "Winkle" Brown on desert island discs. I listened to it fascinated. Probably the most accomplished pilot we will ever know, and so much more. Present at the liberation of Belsen concentration camp. On the panel that interrogated Goering and Himmler, amongst others, following the 2nd world war. Survived over 1400 carrier deck landings, 11 aircraft crashes and 1 shipwreck. Pilot of 487 aircraft types. Despite this, a wonderfully modest and endearing man to listen to, in my opinion.

By some coincidence, he passed away today. I've been watching BBC news channel for the last 90 minutes and nothing has been said about this remarkable man. I heard about his passing on an internet forum. It's all about Boris and the EU.  >:(

Well, rest in peace, Eric.   :'(

Hi All,

I'm after a front headlamp levelling sensor please - preferably one where the linkage hasn't started to seize up!

Also, the securing clips for the panels above the front footwells - plastic "push in and turn 90 degrees" type. Some car kit fitting gorilla couldn't be @rsed to put them all back so I'm after 4 of these please.

Cheers,

Kevin
