Car problems when cold (ran a scan)

[Misc]

I've a Bora 130 diesel and it's been great up until a month or so ago, the first problem was when at higher speeds the car would just lose power and pootle along, which I think was limp mode. Once restarted it was back to normal and the engine warning light would go after a day or so.

The next incident was when the engine would just cut out (driving in a straight line at around 60mph) No funny noises, smoke or smell, and again, if you pulled over and restarted or came to a complete stop the car would drive as normal.

in short my symptoms are

-Starts first time in the mornings, but after warming up, if you turned the car off and tried again it'll take a few cranks.

-Cuts out and loss of power which is reset by switching on/off the engine.



I've ran a demo of Vag-Com and the fault codes are as followed.


-19463 Camshaft Position Sensor (G40) No signal, Intermittent. P3007

-P0341

-P0322

-00668 Supply Voltage Terminal 30 - Implausible signal - Intermittent

-01314


Thanks

Misc, are you close to Maidstone?

I've got a full Palmer ODB2 reader/software if you want to double check any errors on there? Can't guarantee its going to show up much else but it may do.

VAG engines are notorious for the n75 (boost) valve to fail, have that and the egr valve checked, they can both be the source of limp mode, it could also be a turbo issue.

id put my money on maf sensor, if you get a full version of vagcom (torrent) you will be able to monitor the sensor same with the egr sensor, a problem like yours you need to monitor the live data whilst driving it as opposed to relying on a fault code as they can be misleading

Where to start?! Not very likely your going to fix this without taking it to a decent garage who know what they are doing.

Info on those codes https://wiki.ross-tech.com/wiki/index.php/00668

https://wiki.ross-tech.com/wiki/index.php/01314

Looks like you have an intermittant issue causing all if not most of those codes, a failing camshaft sensor would cause the hard starting for sure but with other codes like the 00668 terminal 30 supply and 01314 ecm communication error it could all be down to a wiring issue somewhere.
Has the car had any water ingress that you know of?

N75 is easy to check if its working, its just a solenoid, so put power across the pins and you should be able to blow through it, when you take the power off you shouldn't.

If you unplug the MAF sensor does it run better. if the sensor is unplugged it reverts to a default program, so if unplugging improves it then you have a bad MAF.

All your codes point towards a bad Camshaft Position Sensor. but your symptoms do not, usually a bad Camshaft Position Sensor will give you a check engine light and stalling/bad running at low RPM.

Knowing those, variable vane in the turbo seizing. Can be freed off.

Slight curve ball in the mix, have had very similar to this before a few years back, and again suffered just recently although on a TDCi engine.

Initial fault codes pointed towards cam sensor but after the guy went digging deep, resetting and running the car up the road again, finally deduced low fuel pressure at the higher revs kicking in the limp mode and fault light.

First idea was to change the fuel filter and run a bottle of redex or similar through it on half a tank, problem gone.

Check above mentioned,

Sticky VNT can (sometimes) be fixed by ragging it, got to push lots of air through to blow any crap out, as well as getting it hot, lots of short journeys without the occasional longer run can do it

Failing that innotec turbo cleaner

Camshaft position sensor went on my diesel X Type.

When it went it would randomly cut out and would restart only after a few cranks. Then one day it failed to start for a good few hours and i called the recovery truck who took me home. After getting the car off the truck i tried again and it started!

Went and bought the sensor which was about £15 and took 10 minutes to fit and touch wood, its not done it again in 6 months.

So, change the fucking sensor.

yeah all the speculation is useless when it's showing two intermittent faults which youre not fixing.

the fact that it's even telling you theyre intermittent and that your problem comes and goes tells you those are your problem. or at least your starting point

The fact its throwing a code isn't always a good reason to just throw new sensors at it.

If it is only used for short trips, Give it a long drive with a bit of ragging, It may help the VVT but may not.

On the flip side, Cam sensor won't be much, or hard on a 130 like that IIRC.

As with any fault that is intermitten with various causes, its hard to diagnose, Moreso via the internet!

Thanks everyone! And especially to Paddy for offering his service! May take you up on that in the future.

I ended up taking it to a garage who replaced the camshaft sensor, said it's common with these cars. Car seems to be fine which is all good.

Now I can get the thing sold.

On the polos its very easy, one 5mm bolt and its right on top of the rocker cover. Depends on the engine model as to where they are but cam sensors normally arent too hard to replace.
