General Car Chat / Re: Insignia 2012 Navi 900 Head Unit Part no. 23127750

« on: 01 October 2024, 10:32:24 »

May buy a Grandland X Elite Nav Auto to replace my wife's Insignia from dealer who is going to have a go at Head Unit- trade in value to be adjusted accordingly. A bit bothered about the wet cam belt issues you read about on various makes/models these days. But hey ho.

Drive Vauxhall have agreed to fit replacement unit - explained about codes etc - fingers crossed they can do it - albeit not til 14th October. Otherwise it may be ICEbox Auto Tesla Unit which should work as replacement. Didn't really want to spend much on 13 year old car.

Whole head unit, no sounds at all, no display, even no indicator click sound or parking sensor sound. Main dealer still debating whether to do it or not. The head unit if available would have been £1400. This one is £40 delivered!!

I have the code but the new unit wasn't divorced from donor vehicle. Hope Tech 2 will resolve.

Thank you - have asked breaker if there is a code. If the original unit is dead is it ok just to take out, put new unit in and then worry about code please?

A bit out of the blue I found a part at a breakers in Swindon which will arrive Friday with a one month warranty. Now trying to find someone to fit and code!!  Awaiting Eden Camberley but will likely get "we do not fit second hand parts".

Fuses fine and power to head unit but it is completely dead - looked at some alternatives but this model of Insignia with larger colour screen is proving difficult to get wiring harnesses to accommodate other units eg Pioneer.

Part no longer made by VX and have located one in EU but website reviews not good with faulty stuff being shipped and delays/no refunds.

Any assistance to source a used unit would be great thanks.

Steve - I have had my V90 Inscription for 5 years now and definitely best car I have had. See whether you can get a decent warranty out of the dealer. Careful check on where it is up to on service history. Good luck

No idea why. There seems to be quite a bit of work removing battery compartment according to a couple of you tubes but clearly no appetite from garages around here. We will just run it for now. Has behaved itself for last week.

Thanks both. Still waiting for a couple of sources to come back to me. Didn't expect it to be such a problem

General Car Chat / Insignia 6 speed auto gearbox oil change

« on: 20 July 2024, 10:12:37 »

Maybe 2 or 3 times a day, there is a slight shudder through the gears when slowing down. Car has done 100,000 miles and so I thought rather than go too deep with torque converser etc I would have the oil changed as per a couple of online how to's recognising you cannot get all the oil out in one hit etc. Local garages don't seem to want to take on and a transmission specialist garage says we don't just change oil. They want to change torque converter and oil (at least) without seeing vehicle. Am I getting something wrong here - I know these gearboxes are supposedly sealed for life but there is a drain plug and filler I believe on a 61 plate 2 litre diesel. Any thoughts please?

General Car Chat / Re: Understanding DPF issues

« on: 19 February 2024, 13:37:39 »

The 2.0 CDTi glow plugs also monitor the cylinder pressures, I suspect a faulty one would show a low compression fault code and might also cause a change in the idle. It sounds like this is a confirmed issue given the codes and the fact the cylinder pressure is measured as good so the first job should be to repair this.

DPF regen gets inhibited when many engine faults are active, this is done to protect the system/engine from overheating or bore wash during the active regen phase.

So change the glow plug, ensure the codes are cleared, check the live data to confirm cylinder pressures are good, and go for a good drive to regen the DPF (forces regen should be avoided if possible!), if it does not regen then do a forced one.

Not rocket surgery but, we all know how to many mechanics struggle with the basics these days

Thank you - glo plug changed and all good so far. Just a bit of a long way round to get there. I suppose with hindsight and knowing that only part of the glo plug will throw a code pointing to the glo plug then it would have been  an idea to swap a glo plug over from a cylinder which was not exhibiting a pressure issue. Anyhow - job done now.

Thanks guys - glo plug pressure sensor was the problem.
Basically the glo plug part was working but the pressure sensor part of it was faulty- hence it did not throw a glo plug code but because there was a fault in the system the regen would not work. All seems good and forced regen worked.

General Car Chat / Understanding DPF issues

« on: 17 February 2024, 10:01:37 »

Hi all - not had too many car issues in recent years but just hoping to get a bit of a strange one sorted today.

The Insignia 2.0 diesel auto (2012 93000 miles) has variable revs when at idle which has gone a little worse over last 3 weeks so that you now get a slight hesitation - again only noticeable at idle. The DPF warning came up just before this (say 4 weeks ago) so we gave it a run but haven't done any longish runs since. Took it to independent yesterday who read codes and showing DPF 86% blocked and cylinder low pressure. As they could not do forced regeneration they asked my permission to do cylinder leak test to which I agreed and later in day they came back with no issues and that the fault appears to be one glo-plug (type which has pressure sensor). I had googled all of this and Insignia sites have a lot of posts where this idling issue is prevalent - some have changed loads of parts, others ignore it.

Hoping today brings result but not sure why diagnostic wouldn't go straight to glo-plug fault?
