[OBD Diagnostics on a Renault Clio (04)]

I use vcds on a number of non vag cars and find as good at engine diagnostics as many more expensive code readers, gives lots of info

[Fabia vRS turns over but won't start]

I would definitely check timing belt first, cam sensor easy enough to change.

[Fabia vRS turns over but won't start]

If you cant hear fuel pump check fuses, to check if pump runs pull hose from filter and stick in a bottle turn on key switch and check for flow.

[Fabia vRS turns over but won't start]

Is the fuel pump in the tank running, you can hear it run for about 2 seconds when you turn the key switch on. If it does run switch it on 5 or six times to bleed the fuel system. Check for any diagnostic codes if you have a scanner.

Petrol or Diesel

[PAS light on start up]

You need to read the fault code with vcds, vcds lite is a free download and a cable can be bought for about £20 from somewhere like Gendan.

[Fabia vrs problem non start]

Only a scope would be able to tell you if number one inj.fuel solenoid was operating correctly allowing the inj.to fire instead of returning the fuel to tank.

[Fabia vrs problem non start]

You could check the injecter wiring harness, If it where mine I would use a oscilloscope to test injector solenoids, crank and cam sensor readings, also use a impulse sensor with the scope to check intake and exhaust readings.

[Fabia vrs problem non start]

I find that strange, not aware that pd engine has misfire detection, what's the code number

[Fabia vrs problem non start]

Injectors are adjustable, but they require a dti to set up, I would give it time to settlle down first and check all other sensors for correct readings first.

[Fabia vrs problem non start]

What other codes are you getting, does the engine start with easy start, is the fuel contaminated with water, are compression reading up to spec. Is the crank sensor working.

[MAF sensor wiring help needed]

Google vw maf sensor wirring, plenty of information

[Fabia vrs problem non start]

If your satisfied that tank pump is ok then tandem pump is faulty

[Fabia vrs problem non start]

Even crank pressure should be much higher than the reading you are getting, is the in tank pump delivery up to spec.

[Fabia vrs problem non start]

Tandem pump should be 3-5 bar at idling, tank pump about 15 psi and a delivery of about one litre a minute.

[Got another fabia vrs but not starting]

Fuel pressure at the tandem pump should be 3 bar at idling, in tank pump should deliver about a litre a minute

[Injector resistance - VCDS]

No way of checking pd injectors with vag com, oscilloscope used with a current clamp is book method of checking . They take about 20amps to operate solenoid valve with a 50% reduction in pwm once the solenoid is closed.

[Diagnostics...]

I believe carista will cover all modules on a 2015 Superb

[Fuse Box]

Standard size fuses,

[7 months later... Still a dead car! Yep you read that right 7 months and still not running CANBUS]

Again many thanks for sharing , a very informative video that explains testinhg of can bus signals, have learned a lot from it.

[Any electronics experts here]

Seems like they have given you a 180k ohm instead of 180 ohm.Take it back and change it.

[MK4 Golf GTI 1.8t AUM (same as mk1 octavia vrs?) - Fault Codes]

I think the clue is in the lasr fault code, system to lean, have a good look at all the vacuum hoses for leaks, put a vacuum gauge on the car at idle, you should see 18-21 inches of vac.holding steady. Test ccomponents before replacing them. VCDS is only a starting point in diagnostics dont take everything it tells you as gospel.

[Cold Starting Issues - Running out of ideas!]

This topic now has me wondering if my car has been screwed in the same way!! ive suffered cold start issues since my injectors were replaced by the recall... I ended up having the car back to the garage a few times for various checks as it just didnt seem right!! low down on power etc and every time just got told thats how it is... I now suspect the injectors but loathed to bother as i think im going to rid myself of the car and get something else instead...

Why not start a new thread with your problem, if you suspect your injectors to be loose or the seals have failed, it is an easy fault to diagnose.

[Cold Starting Issues - Running out of ideas!]

All the trying to point the finger of blame at someone someone else is not going to work, the starting fault was there before anyone placed a spanner on the vehicle.. Injectors coming loose on this engine is not unknown, have a look at some off the VW forum.

[Cold Starting Issues - Running out of ideas!]

After what you have already spent the last thing you want to do is a bodge job, it is possible to have the cylinder head bored out and sleeves shrunk in but I dont no what the cost would be against the cost of a new cylinder head,

You could also look round for a low milage replacement engine, needs a lot of careful thought, good luck with whatever you decide. You have certainly made for some interesting discussion on this forum.
